Diabetes mellitus is a metabolic disease of the endocrine system, characterized by chronic hyperglycemia resulting from insulin resistance or defective insulin production. Among the complementary and alternative medicines, diet-based approaches are gaining popularity worldwide for the management of it. Ficus carica, one of the oldest plants cultivated on the earth, is rich in phytochemicals including anthocyanins, phenolics, flavonoids, and organic acids. The present study was designed to analyze the therapeutic potential of dried fig and extract for their potential against hyperglycemia and related complication in the diabetic rat model. Diabetes was induced by using alloxan monohydrate and divided into five groups including Negative-, Positive-, standard drug- group, treated-I (given extract), and treated-II (given 10% dried figs). Fig extract was administered through the intragastric tube, and fig paste was mixed in the feed of the experimental group, and then rats were decapitated after 6 weeks to collect the blood and serum. At the end of the study, biochemical analysis such as fasting blood glucose (FBG), serum glucose, and insulin was performed. Histopathological study of the pancreas showed cell deformation in the positive control group whereas damage was reversed in treated groups. The pancreas was also saved for gene expression analysis. The results revealed that the positive control group has lower expression of INS-1, INS-2, Pdx-1, amylin, and GLUT-2 genes. Results revealed that serum glucose and FBG started to normalize after the administration of treatment (Glibenclamide, dry fig, and fig fruit extract), and insulin concentration also started to improve. 10% dried fig was more effective to control hyperglycemic conditions, which might be due to the presence of fiber. However, the gene expression was more modulated in the group treated with fig extract. The findings of current research suggested the utilization of fig and fig-based products because of their potential to reverse the damage induced by the alloxan or stressors of daily life.
糖尿病是一种内分泌系统的代谢性疾病,以胰岛素抵抗或胰岛素产生缺陷引起的慢性高血糖为特征。在补充和替代药物中,以饮食为基础的治疗方法在世界范围内越来越受欢迎。无花果是地球上最古老的植物之一,含有丰富的植物化学物质,包括花青素、酚类物质、类黄酮和有机酸。本研究旨在分析无花果干及其提取物对糖尿病大鼠模型高血糖及相关并发症的治疗潜力。采用一水四氧嘧啶诱导糖尿病,分为阴性组、阳性组、标准药物组、ⅰ组(给予提取物)、ⅱ组(给予10%无花果干)5组。实验组大鼠经胃管灌胃给予无花果提取物,并在饲料中混合无花果膏,6周后处死大鼠,采集血液和血清。研究结束时,进行空腹血糖(FBG)、血清葡萄糖、胰岛素等生化分析。胰腺组织病理学研究显示,阳性对照组细胞变形,而治疗组损伤逆转。胰腺也被保存下来进行基因表达分析。结果显示,阳性对照组INS-1、INS-2、Pdx-1、amylin和GLUT-2基因表达较低。结果显示,在给予格列本脲、无花果干和无花果果提取物治疗后,血糖和空腹血糖开始恢复正常,胰岛素浓度也开始改善。10%干燥的无花果对控制高血糖更有效,这可能是由于纤维的存在。然而,在用无花果提取物处理的组中,基因表达受到更多的调节。目前的研究结果表明,利用无花果和以无花果为基础的产品,因为它们有可能逆转由四氧嘧啶或日常生活压力源引起的损伤。

Poultry farming is a big business in Pakistan. Poultry farming is a substantial supply of eggs and meat in rural areas, as well as a reliable source of income. Therefore the goal of this study is to compare the Rhode Island red, barred plymouth rock, and their hybrids’ phenotypic traits and egg-laying capacities. The 100-day-old Rhode Island Red, Barred Plymouth Rock, and cross chicks were used in the study at Jaba District Mansehra, KP, Pakistan. The whole flock was sheltered, fed, ventilated, and immunized. Breed 3 (Jabba 21) was reported to have the longest shanks (3.78 inches SL), followed by breed 1 (Rhode Island Red) and breed 2 (Barred Plymouth Rock) (3.47 inches SL). Breed 2 is the broadest shank at 0.47 SW, followed by Breed 1 at 0.43 SW and Breed 3 at 0.30 SW (0.43 Inches SW). The breadth of the shinbone did not change substantially from week 8 to week 13 (p=0.05), although body weight changed from week 1 to week 18. Breed 1 consumed the most feed (2,112 g), followed by Breed 3 (1,452 g) and Breed 2. (990 g). Breed 2 acquired the greatest amount of weight (1,638.57 g), followed by Breed 1 (1,557.07 g) and Breed 3. (1530.3 g). From the first to the eighteenth week of observations, there was a significant (p0.05) difference between the three chicken breeds in weekly body weight gain. Breeds 1, 2, and 3 saw growth rates of 1st 63.59, 2nd 64.02 and 3rd 64.03 percent. This research gave us a fresh perspective on several products that might come to market and contend with one another. This study provides insight into what will work best for Pakistan’s poultry sector going forward in the future.
家禽养殖在巴基斯坦是一项大生意。家禽养殖业是农村地区蛋类和肉类的重要来源,也是可靠的收入来源。因此,本研究的目的是比较罗德岛红、条纹普利茅斯岩及其杂交后代的表型性状和产卵能力。100天大的罗德岛红鸡、条纹普利茅斯岩鸡和杂交鸡在巴基斯坦KP曼塞赫拉贾巴区进行了研究。整个鸡群都得到庇护、喂养、通风和免疫。据报道,品种3(贾巴21)的腿最长(3.78英寸),其次是品种1(罗德岛红色)和品种2(条纹普利茅斯岩石)(3.47英寸)。品种2的柄最宽,为0.47 SW,其次是品种1,为0.43 SW,品种3为0.30 SW(0.43英寸SW)。从第8周到第13周,胫骨宽度没有明显变化(p=0.05),尽管体重从第1周到第18周发生了变化。品种1消耗饲料最多(2112 g),其次是品种3 (1452 g)和品种2。品种2的体重最大(1,638.57 g),其次是品种1 (1,557.07 g)和品种3。(1530.3 g)。观察第1 ~ 18周,3个鸡品种的周增重差异显著(p0.05)。品种1、2和3的增长率分别为第1位63.59%、第2位64.02和第3位64.03%。这项研究让我们对几种可能进入市场并相互竞争的产品有了新的看法。这项研究为巴基斯坦家禽业未来的发展提供了最有效的方法。

The research facility of Avian Research & Training (ART) Center (Poultry Production), UVAS, Lahore was selected to investigate the effect of feeding organic and inorganic zinc in addition to vit-E on the growth performance of Japanese quail. for a period of 6 months. The diet formulated by the inclusion of ZnO + ZnI (mg)+VE(IU) as 0+0+0 (A), 25+0+0 (B), 0+15+0 (C), 0+0+12 (D), 25+15+0 (E), 25+0+12 (F), 0+15+12 (G) and 25+15+12 (H), respectively. The effect of zinc and vit-E on growth and slaughter traits of Japanese quail was significant (P<0.05) and it was perceived that in 6 weeks the broiler quails in groups H and F took higher feed (745.44 and 734.70 g/bird), with simultaneous effect on LBW of males (175.35 and 174.50 g), females (198.35 and 197.38 g), average (186.85 and 185.94 g), intestine filled (6.81 and 6.66 g) and empty weights (5.51 and 4.88 g), intestine length (44.87 and 44.75 g), cecal length (16.37 and 16.12 cm), the weight of carcass + giblets (142.01 and 141.48 g), carcass (130.88 and 130.25 g), heart (2.18 and 2.16 g), liver (5.02 and 5.06 g), gizzard (5.62 and 5.21 g), respectively. The dietary Zn + vit-E inclusion significantly (P<0.05) increased the relative length of gut segments, villi height, villus thickness, the villi height to crypt depth proportion in jejunum and ileum and the number of goblet cells in various parts of the intestine of quails. The meat production was significantly higher in female quails than the meat of male quails. This suggested that the organic Zn proved to be better than the inorganic Zn source in addition to vit-E to achieve physiology-related traits in quails.
选择拉合尔UVAS禽类研究与培训(ART)中心(家禽生产)研究设施,研究在饲粮中添加有机锌和无机锌以及维生素e对日本鹌鹑生长性能的影响。为期6个月。将ZnO + ZnI (mg)+VE(IU)分别配制为0+0+0 (A)、25+0+0 (B)、0+15+0 (C)、0+0+12 (D)、25+15+0 (E)、25+0+12 (F)、0+15+12 (G)和25+15+12 (H)。锌的影响和vit-E日本鹌鹑的增长和屠宰性状显著(P < 0.05),它被认为在6周肉用鸡鹌鹑在F组H和更高的饲料(745.44和734.70 g /鸟),同时影响激光焊的男性(175.35和174.50 g),女性(198.35和197.38 g),平均(186.85和185.94 g),小肠(6.81和6.66 g)和空重量(5.51和4.88 g),小肠长度(44.87和44.75 g),盲肠的长度(16.37和16.12厘米),胴体+内脏重量分别为142.01和141.48 g、胴体重量分别为130.88和130.25 g、心脏重量分别为2.18和2.16 g、肝脏重量分别为5.02和5.06 g、砂囊重量分别为5.62和5.21 g。饲粮中添加Zn +维生素e显著(P<0.05)提高了鹌鹑肠段的相对长度、绒毛高度、绒毛厚度、空肠和回肠绒毛高度与隐窝深度之比以及肠道各部位杯状细胞的数量。雌鹌鹑肉产量显著高于雄鹌鹑肉产量。这说明,除了维生素e外,有机锌比无机锌更有利于鹌鹑生理相关性状的实现。

The objective of the current research is to provide a systematic account of the variety of endemic plant species found in Pakistan, with a focus on family, distribution, and life form status. The existing research effort, which is based on a survey of the literature, field observations, and herbarium records, has identified 306 endemic plant species among 50 genera and 40 families. In accordance with an analysis of the life form or status of these plant species, herbs are dominant (n= 243 species, 80 %), while shrubs (n= 33 species, 11 %), under shrubs (n= 13 species, 4 %), trees (n= 10 species, 4 %), and grasses (n= 7 species, 2 %). The study revealed that Asteraceae is the most dominant family (n= 38 species), while Taraxacum is a dominant genus (n= 23 species). Distribution analysis revealed that the majority of species are distributed in mountainous areas of Pakistan. Khyber Pakhtunkhwa province is rich in endemism (n= 142 species, 37 %). The current study sheds light on Pakistan’s endemism situation. Further research that takes into consideration population levels and new risks is also required. The study will help policymakers in developing conservation strategies.

Tomato leafminer (TLM), Tuta absoluta (Lepidoptera: Gelechiidae), is a serious oligophagous pest of tomatoes. Although originated in South America, it has now been introduced and spread in almost all the tomato-growing areas of the globe. Therefore, studies were undertaken to determine the infestation of T. absoluta on tomato parts at various locations of six main tomato growing areas of Sindh i.e., Badin, Thatta, Mirpur Khas, Hyderabad, Sanghar and Shaheed Benazirabad. Five tomato fields (locations) were randomly selected from each district to determine the infestation of TLM based on its characteristic mines on tomato leaves and fruits. Tuta absoluta infestation was recorded on tomato leaves and fruits observed at all the sampling locations of six districts with significant differences among plant parts, locations, and districts. The highest infestation on leaves (19.36±0.92 %) and fruits (1.36±0.28 %) was observed from location one of Mirpur Khas district. District-wise, overall, the highest infestation of T. absoluta on tomato leaves (17.04±0.38 %) and stems (1.10±0.11 %) was recorded at Mirpur Khas, whereas Shaheed Benazirabad and Hyderabad districts suffered the lowest infestation on leaves (4.18±0.22 %) and fruits (0.26±0.04 %), respectively. The highest infestation of T. absoluta at Badin (14.10±0.28 %), Thatta (11.10±0.27 %), Sanghar (8.22±0.34 %), Hyderabad (5.32±0.18 %) and Shaheed Benazirabad (4.18±0.22 %) was also recorded on leaves. Therefore, early monitoring and management should be taken by growers to restrict the losses of T. absoluta on tomatoes, whereas government should adopt strict quarantine measures on the movement of tomato nurseries to restrict its spread.
番茄切叶螨(Tuta absoluta,鳞翅目:姬蝇科)是严重危害番茄的寡食害虫。虽然它起源于南美洲,但现在已经被引入并传播到全球几乎所有的番茄种植区。因此,在信德省六个主要番茄种植区的不同地点,即Badin、Thatta、Mirpur Khas、Hyderabad、Sanghar和Shaheed Benazirabad,进行了研究,以确定绝对番茄螟对番茄部位的侵染情况。在每个区随机选取5个番茄田(地点),根据其对番茄叶片和果实的特征地雷确定其侵染情况。在6个区所有取样点均记录到番茄叶片和果实侵染,且植株部位、地点和地区间差异显著。以米尔布尔卡斯区1号地点的叶片(19.36±0.92%)和果实(1.36±0.28%)侵染率最高。从地区来看,米尔布尔区和海得拉巴区分别以番茄叶片(17.04±0.38%)和茎部(1.10±0.11%)的侵染率最高,叶片(4.18±0.22%)和果实(0.26±0.04%)的侵染率最低。巴丁(14.10±0.28%)、塔塔(11.10±0.27%)、桑哈尔(8.22±0.34%)、海得拉巴(5.32±0.18%)和沙希德·贝纳齐拉巴(4.18±0.22%)的叶片侵染率最高。因此,种植者应采取早期监测和管理措施,以限制番茄上的绝对白僵菌的损失,而政府应对番茄苗圃的流动采取严格的检疫措施,以限制其传播。

The highest infestation on leaves (19.36±0.92 %) and fruits (1.36±0.28 %) was observed from location one of Mirpur Khas district. District-wise, overall, the highest infestation of T. absoluta on tomato leaves (17.04±0.38 %) and stems (1.10±0.11 %) was recorded at Mirpur Khas, whereas Shaheed Benazirabad and Hyderabad districts suffered the lowest infestation on leaves (4.18±0.22 %) and fruits (0.26±0.04 %), respectively. The highest infestation of T. absoluta at Badin (14.10±0.28 %), Thatta (11.10±0.27 %), Sanghar (8.22±0.34 %), Hyderabad (5.32±0.18 %) and Shaheed Benazirabad (4.18±0.22 %) was also recorded on leaves. Therefore, early monitoring and management should be taken by growers to restrict the losses of T. absoluta on tomatoes, whereas government should adopt strict quarantine measures on the movement of tomato nurseries to restrict its spread.","PeriodicalId":36960,"journal":{"name":"Proceedings of the Pakistan Academy of Sciences: Part B","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41624039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asiatic black bear (Ursus thibetanus) is widely distributed in various countries of Asia including different areas of Pakistan such as District Mansehra, Swat, Kohistan, Battagram, Gilgit Baltistan, and Azad Jammu and Kashmir. The present research was conducted in District Battagram, Khyber Pakhtunkhwa, Pakistan where new and abundant evidence of the Asiatic Black bear was reported. Data were collected during field reports, questionnaire-based surveys and oral interviews, and discussions with the local community from March 2022 to December 2022. The black bear was encountered by local peoples at a low elevated area (1259 m) of Jesol village (N 34o 41' 53" E 73o 03' 05") and was killed collectively (May 12, 2022). During such an encounter, a young man was also injured in conflict. Within one day, local people carried every part of the bear’s body and left the remaining skeleton. The wildlife department of Khyber Pakhtunkhwa took immediate action against the involved people. Similarly, the second black bear was also observed in the same village after one week but this time local people did not take any action against the black bear due to strict enforcement of wildlife law implemented by the wildlife department. On the other hand, questionnaire-based surveys and oral interviews were conducted in different areas of Battagram such as Baliga, Chail, and Shumlai about the black bear population. According to the perception of the local community, a quite good population of bears n=14 (6 males, 4 females, and 4 cubs) are present in the entire district. During the field survey, bear signs were also observed in Balija Mountain such as pug marks, track routing in snow, scat samples, and setting place. Bone samples collected from a killed black bear will be genetically identified for further genotypic study. The black bear population could be conserved by the strict implementation of rules and regulations by the government and conservation agencies. Awareness among the local community also plays an important in black bear conservation.
亚洲黑熊(Ursus thibetanus)广泛分布在亚洲各个国家,包括巴基斯坦的不同地区,如Mansehra区、斯瓦特、Kohistan、Battagram、Gilgit Baltistan和Azad查谟和克什米尔。本研究是在巴基斯坦开伯尔-普赫图赫瓦的巴特格拉姆区进行的,在那里报告了亚洲黑熊的新的和丰富的证据。从2022年3月至2022年12月,通过实地报告、问卷调查和口头访谈以及与当地社区的讨论收集数据。黑熊是当地人在Jesol村(n34o 41' 53" e730 03' 05")的低空高地(1259米)遇到的,并被集体杀死(2022年5月12日)。在这样的遭遇中,一名年轻人也在冲突中受伤。一天之内,当地人把熊身体的每一部分都搬了出去,只留下了剩下的骨架。开伯尔-普赫图赫瓦省野生动物部门立即对涉案人员采取了行动。同样,一周后,在同一村庄也观察到第二只黑熊,但由于野生动物部门严格执行野生动物法,这次当地人没有对黑熊采取任何行动。另一方面,在巴利加、查伊和松莱等巴特格拉姆不同地区对黑熊种群进行了问卷调查和口头访谈。根据当地社区的看法,整个地区有相当多的熊(n=14)(6只公熊,4只母熊和4只幼熊)。在野外调查中,在巴力加山还观察到熊的标志,如哈巴狗的痕迹、雪地上的路线、粪便样本和设置地点。从被猎杀的黑熊身上采集的骨骼样本将进行基因鉴定,以进行进一步的基因型研究。通过政府和保护机构严格执行规章制度,黑熊的数量可以得到保护。当地社区的意识在黑熊保护中也起着重要作用。

Fifty samples of female genital secretions were collected from a group of women whose age ranges from 15 to 50 years old at Al-Batool Hospital for Maternity and Children. The isolates Escherichia coli, Staphylococcus aureus, Candida albicans, and Staphylococcus epidermidis were found in the fungal and bacterial cultures of the samples, with percentages of (45, 31, 13, 11), respectively. Positive samples were isolated at the highest rate of 87 percent for samples isolated from people aged 30 to 40. In the case of pregnancy, there is an increase in the infection rate with fungal and bacterial species, with a percentage of 60 % compared to women. The results of testing the effect of plant extracts (marjoram, chamomile, thyme, peat, and thuja) on isolated bacterial and fungal species showed inhibition diameters (20, 16, 15.5, 13, 10, 10) mm at concentrations (25 %, 50 %, 75 %, 100 %). We discovered that different concentrations of Marjoram, chamomile, thyme, peat, and thuja extracts (25 %, 50 %, 75 %, 100 %) were associated with increased inhibition rates of fungal and bacterial infection with different diameters (10, 12, 15, 16, 20 mm).

Vitamin E (Vit. E) is primarily responsible for the increased antioxidant capacity observed in animal studies. The present research aimed to investigate vitamin E’s effect on haematological and serum biochemical parameters in Kail sheep. Eighteen (18) Kail breed ewes older than two years but not yet pregnant were chosen for this experiment. The animals were randomly divided into three groups (Control, T1, and T2). During the entire experiment, the control group had access to pure water. Vitamin E was administered orally to both groups of ewes daily for 30 days, with Group T1 receiving 150 mg/kg body weight and Group T2 receiving 200 mg/kg body weight. Blood samples were collected on days 0, 15, and 30. The results revealed a significant increase in blood biochemistry parameters such as RBC, HGB, RDW %, WBC, LYM concentration, and LYM (%) in sheep fed Vitamin E. The serum concentration of albumin, globulin, total protein, and AST was significantly increased (P< 0.05). We conclude that the haematological and serum biochemical parameters in Kail sheep were enhanced after an oral dose of vitamin E.
维生素E(维生素E)E)是动物实验中观察到的抗氧化能力增强的主要原因。本研究旨在探讨维生素E对凯尔羊血液学和血清生化指标的影响。本试验选用18只2岁以上未怀孕的鹌鹑母羊。实验动物随机分为对照组、T1组和T2组。在整个实验过程中,对照组只喝纯净水。两组母羊每天口服维生素E, T1组给予150 mg/kg体重,T2组给予200 mg/kg体重,连续30 d。在第0、15和30天采集血样。结果显示,饲粮维生素e显著提高了绵羊血液生化指标RBC、HGB、RDW %、WBC、LYM浓度和LYM(%),显著提高了血清白蛋白、球蛋白、总蛋白和AST浓度(P< 0.05)。由此可见,口服维生素E能改善凯尔羊的血液学和血清生化指标。

Every year, disaster strikes, and led to thousands of casualties and deaths around the world. A meteorological disaster such as a flash flood is a multifaceted hydro-meteorological phenomenon that can cause a huge loss of human life and can create severe economic problems. In this study, techniques based on Geographic information systems and Remote sensing were used to get the flood susceptibility map for District Shangla, Pakistan. For the susceptibility of flash floods, geo morphometric ranking model was used. Various causative factors were considered including; topography, river pattern, and flow accumulation. ALOS PALSAR digital elevation model was used for calculating the required causative factors. Eleven different sub-basins were delineated in the Shangla basin. A total of eighteen morphometric parameters were studied. The morphometric ranking approach (MRA) score was determined with a range of 1 to 5. Rank 5 represents high risk while rank 1 exhibits low risk. The results of the model were categorized into five flood vulnerability classes; very low, low, moderate, high and very high. The total population of Shangla district is 757,810 with a population density of 480 persons per sq km2, and results from this study revealed that 23 % of the total geographic area (364.11 km2) of the district is vulnerable to high flash floods.
每年,世界各地都会发生灾难,造成数千人伤亡。山洪等气象灾害是一种多方面的水文气象现象,可能造成巨大的生命损失,并可能造成严重的经济问题。本研究采用基于地理信息系统和遥感的技术,绘制了巴基斯坦尚格拉地区的洪水敏感性图。对于山洪的易发性,采用了地形地貌分级模型。考虑了各种致病因素,包括:;地形、河流格局和流量积聚。ALOS PALSAR数字高程模型用于计算所需的成因因素。尚格拉盆地划分出11个不同的亚盆地。共研究了18个形态计量学参数。形态计量学分级方法(MRA)的评分范围为1至5。等级5表示高风险,而等级1表示低风险。该模型的结果分为五类洪水脆弱性;非常低、低、中等、高和非常高。Shangla区总人口757810人,人口密度为每平方公里480人,研究结果显示,该区总地理面积(364.11平方公里)的23%易受高山洪的影响。

Economic concern over fossil fuel reserves, extensive increase in CO2 emission, and change in the world climate due to the combustion of carbon sources have been driving the attention of both commercial and academic researchers towards new sustainable fuel routes to encounter rapidly growing worldwide population demands. In the present study, we have focused on catalytic transesterification towards the environmentally friendly biodiesel synthesis which is low cost, easily implemented and best alternative source of fossil fuels. Herein three triorganotin(IV) carboxylates derivatives namely trimethylstannyl cyclopentanecarboxylate, tributylstannyl cyclopentanecarboxylate and triphenylstannyl cyclopentanecarboxylate were resynthesized according to our reported procedure and theoretically investigated through DFT by applying LANL2DZ as functional with B3LYP basis set (level of theory) to calculate Molecular Electrostatic Potential (MEP) to determine electrophilic center of complexes and Lewis acidity. Owing to the Lewis acid character, the synthesized complexes were then used as catalysts in the transesterification reaction of castor oil. Different reaction parameters were also optimized to obtain maximum biodiesel yield. Synthesized castor oil biodiesel (COB) was characterized and confirmed by employing multitude spectroscopic techniques. The present study evaluated that these complexes can be potential candidates for biodiesel conversion from non-edible and cheap feedstock.
对化石燃料储量的经济关注、二氧化碳排放的广泛增加以及碳源燃烧导致的世界气候变化,促使商业和学术研究人员关注新的可持续燃料路线,以满足快速增长的全球人口需求。在本研究中,我们重点研究了催化酯交换法合成环境友好型生物柴油,这是一种低成本,易于实现的化石燃料的最佳替代来源。本文按照本研究的方法合成了三有机锡(IV)羧酸衍生物三甲基锡基环戊烷羧酸酯、三丁基锡基环戊烷羧酸酯和三苯基锡基环戊烷羧酸酯,并以LANL2DZ为泛函,以B3LYP基集(理论水平)计算分子静电势(MEP),确定配合物的亲电中心和Lewis酸度,通过DFT进行了理论研究。由于所合成的配合物具有Lewis酸的性质,将其用作蓖麻油酯交换反应的催化剂。并对不同的反应参数进行了优化,以获得最大的生物柴油产率。采用多光谱技术对合成的蓖麻油生物柴油(COB)进行了表征和鉴定。本研究评估了这些配合物可以从不可食用和廉价的原料转化为生物柴油的潜在候选物。
