Field experiment was conducted during 2016-17 and 2017-18 to study the response of rice genotypes on Growth and morpho-physiological parameters under three nitrogen levels 120 kg N ha-1, 80 kg N ha-1 and 40 kg N ha-1 as main treatments and twenty rice genotypes as sub treatments, which was carried out at experimental site of Department of Plant Physiology, IGKV, Raipur (C.G.) with Split plot design along with two replications. In the present investigation among the nitrogen treatments, application of 120 kg N ha-1 recorded significantly higher values for growth and morpho-physiological parameters such as plant height, number of tillers/plant, number of effective tillers/ plant, number of panicle/m2, panicle length, flag leaf area, specific leaf area and specific leaf weight. Among the genotypes, DXD (124)-17-193 followed by DXD (124)-17-192 and DXD (124)-3-28 recorded the maximum grain yield even under all the treatments, which also gives better result on the other growth and morpho-physiological parameters. This indicated that maximum yield can be attributed to maximum number of panicles, more photosynthetic rate, more tillers and effective tillers, more flag leaf area, maximum specific leaf weight and minimum specific leaf area.
本试验于2016-17年和2017-18年在赖布尔省IGKV植物生理研究所试验点采用2个重复的分割小区设计,研究了不同水稻基因型在120 kg N ha-1、80 kg N ha-1和40 kg N ha-1 3个氮肥水平下对水稻生长和形态生理参数的响应。在本研究中,施用120 kg N hm -1显著提高了植株的生长和形态生理参数,如株高、分蘖数、有效分蘖数、穗数/m2、穗长、旗叶面积、比叶面积和比叶重。各基因型中,DXD(124)-17-193、DXD(124)-17-192和DXD(124)-3-28在各处理下均取得最大产量,在其他生长和形态生理参数上也有较好的表现。这表明,最高产量可归因于最大穗数、更高的光合速率、更多的分蘖和有效分蘖、更大的旗叶面积、最大比叶重和最小比叶面积。

An Ionic Liquid Based Ultrasonic Assisted Extraction (ILUAE) was developed for profitable extraction of diosgenin from fenugreek leaves. Imidazolium based ionic liquids (ILs) differing in their anions was used as catalytic agent for extraction procedure in order to optimize the diosgenin extraction. Five ionic liquids, concentration of ILs, reaction time and solid to liquid ratio were optimized on one at the time procedure. The particle size was considered the same for all experiments [BMIM]HSO4 was selected as the best IL and in the final optimized condition, the extraction efficiency increased from 0.77 to 10.24 (mg g-1dw) diosgenin. The method was also used to evaluate the concentration of diosgenin in different 13 accessions of Iranian fenugreek cultivated in the same place. The highest concentration of diosgenin with 20.2 and 20.1 (mg g-1dw) were found in the Khash and Qaen accessions, respectively. Accession of Mashhad showed the lowest concentration with 6.8 (mg g-1dw) diosgenin. After the reaction, the ILs from the media was also recovered using SPE column with more than 75% of yield. The result of this study showed that the optimized condition could extract the diosgenin almost five times more than the conventional method which could introduce fenugreek especially the best accession, as a new potential crop and source of diosgenin in the pharmaceutical industry
研究了离子液体超声辅助提取胡芦巴叶薯蓣皂苷元的方法。以阴离子不同的咪唑类离子液体为催化剂,对薯蓣皂苷元的提取工艺进行了优化。对五种离子液体、il浓度、反应时间和料液比进行了一次优化。在各实验粒径相同的条件下,选择[BMIM]HSO4作为最佳IL,在最终优化条件下,薯蓣皂苷元的提取率由0.77 (mg g-1dw)提高到10.24 (mg g-1dw)。并采用该方法对同一地区栽培的13个不同品种胡芦巴中薯蓣皂苷元的含量进行了测定。薯蓣皂苷元的最高含量分别为20.2 (mg g-1dw)和20.1 (mg g-1dw)。加入的马什哈德薯蓣皂苷元含量最低,为6.8 (mg g-1dw)。反应后,介质中的il也可以用SPE柱回收,收率达75%以上。结果表明,该工艺提取薯蓣皂苷元的提取率是常规方法的近5倍,可将胡芦巴尤其是胡芦巴的最佳添加物作为薯蓣皂苷元的新作物和新来源推广应用

The article describes the synthesis and characterization of Ni-flavonoid complex, Cu-flavonoid complex and Znflavonoid complex. The complexes and the flavonoid extracts were characterized using FTIR and UV-Visible spectrophotometer. The results for FTIR spectra clearly showed the formation of complexes as the bands assigning to the carbonyl group C=O shifted to the lower wave number when compared with that of the free ligands. The complexes and the flavonoids extracts when analyzed using UV-Visible spectrophotometer, most of the spectra of the complexes were absorbed at the range of 200 nm to 400 nm and all the spectra of the flavonoids extracts were also absorbed between 200 nm to 400 nm. These results revealed that complexes were formed at slightly acidic condition between the pH values 3.51 to 4.65. In general the results revealed that the conductivity values of Niflavonoid complexes A‹Â‚Cu-flavonoid complexes A‹Â‚Zn-flavonoid complexes. The lowest conductivity of all the complexes was obtained from Zn-flavonoid complexes as a result of its largest surface area, weak bonding and being far away from the nucleus. Therefore, Ni-flavonoid complexes had higher conductivity because of their small surface area and are closer to the nucleus and having stronger bonding than Cu-flavonoid complexes and Znflavonoid complexes. The highest melting point of all the complexes was obtained from Zn-flavonoid complex of Ocimum gratissimum while the lowest melting point was obtained from Ni-flavonoid complex of Moringa oleifera. Niflavonoid complex of Moringa olifera had shorter time to be melted than all the complexes and weak bonding exist in the complex but Zn-flavonoid complex of Ocimum gratissimum had strong bonding and take longer time to be melted
本文介绍了镍类黄酮配合物、铜类黄酮配合物和锌类黄酮配合物的合成和表征。利用红外光谱(FTIR)和紫外可见分光光度计对配合物和黄酮类提取物进行了表征。FTIR光谱结果清楚地表明,与自由配体相比,羰基C=O的波段向低波数移动,从而形成了配合物。用紫外可见分光光度计对配合物和黄酮类提取物进行分析时,在200 ~ 400 nm范围内吸收了配合物的大部分光谱,在200 ~ 400 nm范围内吸收了黄酮类提取物的所有光谱。结果表明,在pH值为3.51 ~ 4.65的微酸性条件下,配合物形成。总体结果表明:类黄酮配合物A′Â、类黄酮配合物A′Â、类黄酮配合物zn′Â的电导率值。类黄酮锌配合物的电导率最低,因为它的表面积最大,成键弱,离原子核远。因此,ni -类黄酮配合物比cu -类黄酮配合物和zn类黄酮配合物具有更小的表面积和更接近细胞核、更强的键合能力,因此具有更高的导电性。所有配合物的熔点最高的是木犀草锌类黄酮配合物,熔点最低的是辣木镍类黄酮配合物。辣木ni黄酮配合物的熔化时间短于其他配合物,存在较弱的键合,而木锌黄酮配合物的熔化时间长

This investigation aimed to evaluate the wound healing and antioxidant potentials of the novel Poly-herbal Formulation (PHF) in diabetic rat’s models and in-vitro antioxidant assays respectively. The wound models viz., excision, incision and dead space by using wistar strain albino rats were adopted for this investigation. The free radical scavenging assays were employed for investigation of Antioxidant potential. The constraints studied for assessment of wound repair were percentage closing percentage of wound, tensile strength of repaired tissue, breaking strength of granulation tissue and valuation of hydroxyproline content on dried tissue. The histopathological sections of granulation tissues obtained in dead space wound model were studied for the distribution of collagen and other histopathological changes. Four groups were used in this study with six animals each. Group I and Group II acts as normal control and diabetic control whereas Group III and Group IV was used as glibenclamide treated (1 mg/kg b.w.), and PHF (500 mg/kg b.w.) treated group respectively. On the other hand the various antioxidant assays like DPPH, scavenging assays, hydrogen peroxide assay etc. were investigated. The PHF has been significantly healing the wounds in diabetic rats within 18 days, while diabetic control rats healed the wound about 86.12 %. Significant (p<0.01) increase in wound breaking strength as well as epithelialization and the level of hydroxyproline was observed in PHF treated animals comparison with diabetic control group. PHF has also shown significant antioxidant potential in in-vitro assays. All these investigations indicate the significant wound healing and antioxidant potential of PHF.
本研究旨在评价新型复方中药(PHF)在糖尿病大鼠模型中的创面愈合和体外抗氧化能力。实验采用wistar毒株白化大鼠的伤口模型:切除、切口和死腔。采用自由基清除法研究其抗氧化能力。评价创面修复的约束条件为创面闭合率、修复组织的抗拉强度、肉芽组织的断裂强度和干燥组织的羟脯氨酸含量。取死腔伤模型肉芽组织的组织病理切片,观察胶原蛋白的分布及其他组织病理变化。本研究分为四组,每组6只。I组和II组分别作为正常对照组和糖尿病对照组,III组和IV组分别作为格列苯脲治疗组(1 mg/kg b.w)和PHF治疗组(500 mg/kg b.w)。另一方面,对DPPH、清除、过氧化氢等抗氧化实验进行了研究。PHF对糖尿病大鼠创面有明显的愈合作用,创面在18 d内愈合,而糖尿病对照组创面愈合率为86.12%。与糖尿病对照组相比,PHF处理动物创面断裂强度、上皮化和羟脯氨酸水平均显著(p<0.01)升高。PHF在体外试验中也显示出显著的抗氧化潜力。这些研究表明,PHF具有显著的伤口愈合和抗氧化潜力。

The leaf of Ficus vogelii is commonly used as a green-leafy vegetable in Northern Cross River State of Nigeria. Its ethanol extract is used by adults for well-being, while its aqueous extract is used for weaning children and for treatment of pediatric anemia. In this study, the methanol and n-hexane fractions of the leaves were analyzed for volatile organic composition using GC-MS in order to determine the class of constituents that may be responsible for the amelioration of anemia and sustenance of well-being in adults. GC-MS analysis of n-hexane and methanol fractions revealed the presence of several organic constituents including twenty-one (21) volatile compounds in nhexane fraction and thirty-five (35) compounds in methanol fraction. The dominant compounds in the n-hexane fraction included, Hexadecanoic acid (3.14%), n-Nonadecanoic acid (17.81%), Phytol (38.45%), Oleic acid (21.20%) and E-2-Octadecadecen-1-ol (4.77%); while the dominant compounds in methanol fraction included, Glycerin (8.44%), Dimethyl sulphoxide (7.44%), 2(R), 3(S)-1,2,3,4-Butane tetrol (6.47%), 17α-OH-17 β-Cyano-Preg-4-en-3one (3.10%), Ethyl-β-d-glucopyranoside (7.25%), Bicyclo [3.1.0] hexan-3-ol (10.11%); n-Hexadecanoic acid (15.42%) and Oleic Acid (21.40%). It was concluded that the presence of Palmitaldehyde diisopentyl acetate (2.52%) in the n-hexane fraction may contribute significantly to the pleasant flavor of the extract fraction and its nutritional acceptability. It was also concluded that the high content of oleic acid and phytol in the plant may be responsible for the cardiovascular benefits the plant confers on the populations consuming it, as both compounds are known to lower blood cholesterol lipids in adult humans.
在尼日利亚的北克罗斯河州,无花果的叶子通常被用作绿叶蔬菜。它的乙醇提取物被成年人用于健康,而它的水提取物被用于断奶儿童和治疗儿科贫血。在这项研究中,使用气相色谱-质谱分析了叶子的甲醇和正己烷部分的挥发性有机成分,以确定可能对改善贫血和维持成年人健康负责的成分类别。正己烷和甲醇组分的GC-MS分析显示,正己烷组分中存在21种挥发性化合物,甲醇组分中存在35种挥发性化合物。正己烷馏分中主要化合物为:十六烷酸(3.14%)、正壬烷酸(17.81%)、叶绿醇(38.45%)、油酸(21.20%)和e -2-十八烯-1-醇(4.77%);甲醇馏分中主要化合物为甘油(8.44%)、二甲基亚砜(7.44%)、2(R), 3(S)-1,2,3,4-丁烷四醇(6.47%)、17α-OH-17 β- cyano - preg -4-烯-3one(3.10%)、乙基-β-d-葡萄糖吡喃苷(7.25%)、双环[3.1.0]己烷-3-醇(10.11%);正十六酸(15.42%)和油酸(21.40%)。结果表明,正己烷馏分中醋酸棕榈醛二异戊酯(2.52%)的存在可显著改善提取馏分的风味和营养接受度。研究还得出结论,这种植物中油酸和叶绿醇的高含量可能是食用这种植物的人群对心血管有益的原因,因为已知这两种化合物都能降低成年人的血胆固醇。

Starting from immemorial time; peoples traditionally used herbs and plants to treat different human and animals ailments. This initiated scientists to investigate on traditional medicinal plants and herbs for biological activities by checking through bioassay and then isolating the bioactive constituents from biologically active medicinal plants and herbs. The different parts of Carissa carandas have been used for various human ailments. It has been used by traditional healers in the treatment of scabies, intestinal worms, pruritus, biliousness, snake-bite/poisoning, astringent, anemia, stomachache, diarrhea, rheumatism, earache, anthelmintic, female libido, hyperdipsia, anorexia, intermittent, mouth ulcer and sore throat, syphilitic pain, burning sensation fever, biliary dysfunction and also used as appetizer, antimicrobial, anti-fungal, analgesic, anti-inflammatory and anti-scorbutic. Its biological activities have been reported by different researchers as hepatoprotective, neuropharmacological, anticancer, antioxidant, anticonvulsant, antiulcer, anthelmintic, analgesic, anti-inflammatory, cardiovascular, antinociceptive, anti-diabetic, anti-pyretic, cardiotonic, histamine releasing, DNA damage inhibition, constipation, anti-diarrheal, antihyperlipidemic, antibacterial, antiviral, cytotoxic potential and diuretic. Its phytochemical constituents which impart medicinal value to the plant was reported as alkaloids, carbohydrates, glycosides, unsaturated sterols, phenolics, saponins, flavonoids, steroids, triterpenoids, tannins, proteins, cardiac glycosides, phytosterol, phlobatannins, leucoanthocyanin, chalcones, coumarin, anthracyanin, emodin, minerals acids, vitamins and anthraquinone glycosides. So far 14 compounds have been isolated from roots, 40 compounds from fruits and 19 compounds from leafs. These compounds include phenolic, alkaloids, sterols, terpenoids, simple acids, simple ester, sesquiterpenes, carboxylate, amino acids, glucose and galactose, sterols glycosides, phenolic lignin. Hence we reviewed the traditional uses, extraction methods, pharmacological uses and phytochemical constituents of Carissa carandas.

Rind and aril of pomegranate (Punica granatum) were freeze-dried and extracted using solvents of varying polarity: petroleum ether, dichloromethane, ethyl acetate, methanol and water. Phytochemical investigations included qualitative detection of phytochemicals including phenols and tannins, flavonoids, anthocyanins, coumarins, quinones, saponins, steroids, triterpenoids, and alkaloids. Total phenolic and flavonoid content of each extract were determined quantitatively. Methanolic and aqueous pomegranate rind extracts showed highest amount of phenolic and flavonoid content. The presence of gallic acid in pomegranate rind and aril was determined by GCMS. Medicinal studies comprised of evaluating the antioxidant, antidiabetic and antibacterial potential of the prepared extracts. According to 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay for antioxidant potential, methanolic and aqueous extracts of pomegranate rind and methanolic extract of pomegranate rind showed antioxidant activity of above 80%. Aqueous extract of pomegranate aril showed highest inhibition of alpha-amylase which was taken as antidiabetic activity according to 3,5-dinitrosalicylic acid assay (DNSA assay). Methanolic and aqueous extracts of pomegranate rind were most effective in inhibiting the growth of a number of bacteria according to the disc diffusion method.
