The study is regarded for standardization of aerial parts of the plant Phyllanthus maderaspatensis L., phytochemical investigations, isolation of flavonoids and evaluation for thrombolytic activity of alcoholic extract and butanolic fraction of alcoholic extract. Standardization study includes macroscopy, microscopy and determination of proximate values and phytochemical investigations include extraction of coarsely powdered herb with exhaustive alcoholic and aqueous extractions and successive extraction with petroleum ether, chloroform and alcohol. The extracts were subjected to qualitative chemical analysis, chromatographic studies [Thin Layer Chromatography (TLC) and High Performance Thin Layer Chromatography (HPTLC)] were performed for flavonoids detection in alcoholic extract. Isolated two flavonoids from butanolic fraction of alcoholic extract by column chromatography and preparative TLC, their partial characterization was done with Proton Nuclear Magnetic Resonance (PNMR) and Fourrier Transform Infrared (FT-IR) spectral data. Thrombolytic activity of alcoholic extract and butanolic fraction of alcoholic extract (20 and 10 mg/100 µl) were evaluated in incubated blood. An attempt made to standardize aerial parts of P. maderaspatensis L., was successful. Two flavonoids were isolated; the alcoholic extract showed significant thrombolytic effect in comparison with thrombosis control in comparison with standard thrombolytic agent streptokinase (30000 unit/100 µl).

Helminthiasis causes losses in livestock production, and anthelminthics are used to treat helmintic infections. Resistance has necessitated the need for development of more effective alternatives. Plants offer a promising alternative and, in Meru County, traditional plant-based treatments for helminthiasis have been used, although there is a lack of scientific proof of their efficacy. The aim of this study was to investigate efficacy of Bridelia micrantha, Aframomum zambesiacum, Hagenia abyssinica, Rubus apetalus, Thespecia garckeana, Physalis peruviana and Caesalpina volkensii against Haemonchus contortus. It entailed screening of methanolic extracts of these plants against Haemonchus contortus, from sheep farms in Muguga Kenya. Their efficacy was tested in-vitro using eggs and larvae of Haemonchus contortus. Egg hatchability was determined after 48-h incubation with extracts while larvae survival was determined after six days incubation. Physiological saline was the negative control while albendazole was the positive control. One-way ANOVA was conducted followed by Tukey’s test. P. peruviana and R. apetalus, inhibition percentages of 95.24±0.54, 90.00±1.00, 88.24±0.66 and 96.55±0.45, 85.71±0.79, 82.14±0.76 at 50, 25 and 12.5 mg/ml respectively was achieved with no significant difference (P<0.05) in egg hatchability with the positive control. The highest larvicidal mean percentage of 100.00±0.00 was achieved by R. apetalus and H. abyssinica across the three dosages with no significant difference between them and albendazole. GC-MS analysis revealed compounds such as terpenoids were conspicuously present which accounted for some of the activity. This observation lenders support to the traditional use of the plant extracts for the treatment of suspected helminthic infections.  Key words: Haemonchus contortus, anthelmintic, essential oil, monoterpenoids, terpenes.
寄生虫病给牲畜生产造成损失,驱虫药被用来治疗寄生虫感染。由于抗药性的存在,有必要开发更有效的替代品。植物提供了一种很有希望的替代方法,在梅鲁县,人们已经使用了传统的基于植物的治疗寄生虫病的方法,尽管缺乏对其有效性的科学证明。研究了薇甘菊、赞besiacum、Hagenia abyssinica、无瓣草、The especia garckeana、Physalis peruviana和Caesalpina volkensii对弯血螨(Haemonchus conttus)的药效。它需要筛选这些植物的甲醇提取物,以对抗来自肯尼亚穆古加绵羊农场的弯曲血蜱。用扭曲血蜱卵和幼虫进行体外药效试验。提取液孵育48 h后测定卵的孵化率,孵育6 d后测定幼虫的存活率。生理盐水为阴性对照,阿苯达唑为阳性对照。采用单因素方差分析,然后进行Tukey&rsquo检验。在50、25和12.5 mg/ml浓度下,紫花田鸡和无瓣田鸡的抑菌率分别为95.24±0.54、90.00±1.00、88.24±0.66和96.55±0.45、85.71±0.79、82.14±0.76,卵孵化率与阳性对照无显著差异(P<0.05)。无瓣田鼠和深草田鼠在3个剂量下的平均杀虫率最高,为100.000 ±0.00,与阿苯达唑无显著差异。气相色谱-质谱分析显示,萜类化合物明显存在,这占了一些活性。这一观察结果为传统上使用植物提取物治疗疑似寄生虫感染提供了支持。关键词:血蜱,驱虫药,精油,单萜类,萜烯类

Dracaena steudneri Engl. (family Dracaenaceae) has been used in managing various health conditions. This study evaluated its pharmacognostic, physicochemical and phytochemical parameters. The physicochemical analysis was done using WHO recommended parameters such as moisture content, ash values (total ash, water soluble ash, acid insoluble ash) and extractive values. Phytochemical screening was done by methods described by Sofowora, Kokate and Prashant. The morphological studies exhibited the macroscopic characters while the microscopic study showed the presence of various characteristics such as vascular bundles, calcium oxalate crystals and paracytic stomata. Physicochemical evaluation indicated 13.7% total yield, 9.13% moisture content, 0.17% water soluble ash, 0.17% acid insoluble ash, 3.41% water insoluble ash, 0.84% acid insoluble ash, 16.25% acid soluble extractive value and 20% water soluble extractive value. The qualitative phytochemical screening revealed the presence of alkaloids, flavonoids, terpenoids, saponins, tannins, glycosides and phenols in the extract. The pharmacognostic characters described in this study will help in identifying the plant and crude drug. The standardization parameters obtained will ensure the efficacy of the drug and also distinguish the drug from its adulterants. Key words: Dracaena steudneri, physicochemical, phytochemical, organoleptic evaluation.

This work was carried out to evaluate the total phenolic content and antioxidant potential (2,2-di-phenyl-1-picrylhydrazyl [DPPH] and ferric reducing antioxidant power [FRAP] methods) of Bauhinia monandra through its organs (leaves, stems and roots). The results showed fluctuating contents with a dominance in the leaves of total phytophenols in the crude hydromethanolic and selective AcOEt extracts (57.344 ± 12.35 and 48.165 ± 4.77 mg EAG/g DM, respectively) and of total flavonoids in the AcOEt extract (100.588 ± 12.06 mg EQ/g DM). The evaluation of antioxidant activity shows that the AcOEt extract of the stems is the most active with a CR50 = 23.442 µg/ml (DPPH method) and 44.34 ± 0.1 µg EVc/100 g DM and 182394.94 ± 406.09 µg EFeSO4/g DM (FRAP method).
本研究通过紫荆叶、茎、根等器官对其总酚含量和抗氧化能力(2,2-二苯基-1-苦基肼[DPPH]和铁还原抗氧化能力[FRAP])进行了评价。结果表明,黄芪提取物的总酚含量(57.344±12.35 mg EAG/g DM)和黄芪提取物的总黄酮含量(100.588±12.06 mg EQ/g DM)在叶片中占主导地位,黄芪提取物的总酚含量(57.344±12.35 mg EAG/g DM)在叶片中占主导地位。抗氧化活性评价结果表明,茎部AcOEt提取物的抗氧化活性最高,CR50 = 23.442µg/ml (DPPH法)、44.34±0.1µg EVc/100 g DM和182394.94±406.09µg EFeSO4/g DM (FRAP法)。

Bioactive evaluation for wound healing of stem back extracts of Acacia nilotica Linn. (Fabaceae) 刺槐茎背提取物伤口愈合的生物活性评价。(豆科)
Pub Date : 2022-11-30 DOI: 10.5897/jpp2022.0621

Acacia nilotica (Linn) is an important medicinal plant, found in Africa, the Middle East, and the Indian subcontinent as well as in Sokoto State, Nigeria. It has been utilized to treat wounds and intestinal disorders among other uses. It has been estimated that nearly 6 million people suffer from chronic wounds worldwide. Even though several conventional drugs are known to increase healing in different kinds of injuries, most are complicated, expensive, and limited in activity. Hence, in this study the stem back crude methanolic extract of A. nilotica was evaluated for wound healing activity using the wound excision model. The plant's stem bark was extracted by maceration using distilled water and methanol to obtain a crude methanol extract (CME). The CME was screened phytochemically and prepared into ointment before subjecting to wound healing assay using the excision wound model in Wister albino rats. The results showed the presence of rich phenolic phytoconstituents, especially of tannins and saponins which were attributed to aid wound healing based on literature. Consequently, the wound healing activity of 10% CME was comparable significantly (P<0.05), to that of povidone-iodine (5% w/w), while that of 2. 5 and 5% were less. The study demonstrated that topical application of CME hastens wound healing and thus provided proof of its folklore use for wound healing
尼罗卡相思是一种重要的药用植物,在非洲、中东、印度次大陆以及尼日利亚索科托州都有发现。它已被用于治疗伤口和肠道疾病等用途。据估计,全世界有近600万人患有慢性创伤。尽管已知有几种传统药物可以促进不同类型损伤的愈合,但大多数药物都很复杂、昂贵,而且疗效有限。因此,在本研究中,我们采用伤口切除模型来评估尼罗卡茎背粗甲醇提取物的伤口愈合活性。用蒸馏水和甲醇浸渍法提取该植物茎皮,得到粗甲醇提取物(CME)。经植物化学筛选后制成软膏,应用Wister白化病大鼠切除创面模型进行创面愈合试验。结果表明,黄芪中含有丰富的酚类植物成分,尤其是单宁和皂苷,文献认为其具有促进伤口愈合的作用。因此,10% CME与聚维酮碘(5% w/w)的创面愈合活性具有显著性差异(P<0.05);5%和5%更少。研究表明,局部应用CME加速伤口愈合,从而提供了民间使用其伤口愈合的证据

Adansonia digitata is a tree plant used in west African local pharmacopoeia. This work aimed to evaluate the wound healing properties of its trunk bark’s hydroethanolic extract in wistar rats. The model of excision wound was used. Wistar rats were treated post-excision topically with neutral carbopol gel (Control), carbopol gels containing 2.5 and 5% of A. digitata hydroethanolic trunk bark extract (ADHE) and L-Mesitran. Pictures were taken post excision for analysis. Biopsies were realized for histological examination of the skin excised and for hydroxyproline determination. In vitro membrane stabilization anti-inflammatory test, DPPH and FRAP antioxidant tests, and phytochemical tests were performed. The results show a better rate of contraction in ADHE 2.5 and 5% animals (+56 ± 0.52% and +68 ± 0.24% respectively) as earlier as on day three post-excision. The hydroxyproline assay confirmed a better collagen production in ADHE 2.5% and 5% animals (+102.5 ± 2.9%, and +107 ± 3.0% respectively). Histological analysis showed a rapid re-epithelialization in ADHE animals. The anti-inflammatory test indicated an IC50 of 16.521 ± 0.525 µg/mL, very close to Aspirin (16.826 ± 0.341 µg/mL), showing a possible anti-inflammatory activity of ADHE. The extract reduced DPPH radical (IC50 of 344.985 ± 17.139 µg/mL) and ferric ions (EC50 = 178.689 ± 0.250 µg/mL). Phytochemical investigations revealed the presence of alkaloids, terpenoids, and polyphenolic compounds. Flavonoids in particular, with an amount of 51.694 ± 0.174 mgER/g, should explain the wound healing activity observed, making the hydroethanolic extract of A. digitata a potential remedy for excision wounds.
adansononia digitata是西非当地药典中使用的一种乔木植物。本工作旨在评价其干皮氢乙醇提取物对wistar大鼠的伤口愈合性能。采用切除创面模型。Wistar大鼠切除后局部注射中性卡波波凝胶(对照)、含2.5和5%马地黄氢乙醇树干树皮提取物(ADHE)的卡波波凝胶和l -美西坦。切除后拍照分析。对切除皮肤进行组织学检查和羟脯氨酸测定。体外膜稳定抗炎实验、DPPH和FRAP抗氧化实验以及植物化学实验。结果显示,ADHE浓度为2.5和5%的动物在切除后第3天收缩率较好(分别为+56±0.52%和+68±0.24%)。羟脯氨酸实验证实,ADHE 2.5%和5%的动物胶原蛋白产量更高(分别为+102.5±2.9%和+107±3.0%)。组织学分析显示ADHE动物可快速再上皮化。抗炎实验显示,ADHE的IC50值为16.521±0.525µg/mL,与阿司匹林的IC50值(16.826±0.341µg/mL)非常接近,提示ADHE可能具有抗炎作用。提取物降低DPPH自由基(IC50 = 344.985±17.139µg/mL)和铁离子(EC50 = 178.689±0.250µg/mL)。植物化学研究发现了生物碱、萜类和多酚类化合物的存在。其中黄酮类化合物的含量为51.694±0.174 mgER/g,可以解释所观察到的伤口愈合活性,使马地黄水乙醇提取物成为治疗切除伤口的潜在药物。

Cancer is one of the major public health problems of the 21st century. Its incidence is increasing in both developed and low-income countries. This trend is justified by the change in people's lifestyles. Cancer of the prostate is one of major cancer types affecting male population. The present study focused on the use of methanolic extract of Striga hermonthica (Delile) Benth. to evaluate total phenolics and flavonoids contents, antioxidant activities, anti-proliferative and anti-migratory effects, using ATCC prostate cancer cell lines (22RV1, DU145, C4-2 and RWPE-1). Total phenolics and flavonoids content were estimated using spectrophotometric methods. Antioxidant potential was evaluated using three methods while cytotoxicity assay, anti-migratory assay and western blot analysis were used for the determination of extracts anti-proliferative activity on prostate cancer cells. Therefore, to assess apoptosis induction in prostate cancer cell lines, the effect of S. hermonthica (Delile) Benth. methanolic extract was investigated on procaspase-3, procaspase-8, and cyclin-B 2 expression. A range of half-dilution concentrations beginning from 500 µg/mL have been prepared to determine the IC 50 in the various tests. Antioxidant compounds were shown to be promising biomolecules, with particular interest in cancer management. Among plant derivative compounds, phenolics and derived molecules have endorsed antioxidant capacities and potential anti-proliferative activities. The best inhibition was obtained on C4-2 cells with an IC 50 = 65.76 µg/mL and a selectivity index of 2.35. The results obtained from this study could partially justify the traditional indications of this plant in the treatment of prostate cancer.
癌症是21世纪主要的公共卫生问题之一。其发病率在发达国家和低收入国家都在增加。人们生活方式的改变证明了这种趋势是合理的。前列腺癌是影响男性人口的主要癌症类型之一。本研究主要研究了白刺草(Striga hermonthica, Delile) Benth)甲醇提取物的应用。以ATCC前列腺癌细胞(22RV1、DU145、C4-2和RWPE-1)为研究对象,评价其总酚类物质和总黄酮含量、抗氧化活性、抗增殖和抗迁移作用。用分光光度法测定总酚类和总黄酮含量。采用细胞毒性试验、抗迁移试验和western blot法测定提取物对前列腺癌细胞的抗增殖活性。因此,为了评估其对前列腺癌细胞的诱导凋亡作用,本研究采用紫花苜蓿(Delile) Benth。研究甲醇提取物对procaspase-3、procaspase-8和cyclin- b2表达的影响。已准备了从500微克/毫升开始的半稀释浓度范围,以确定各种测试中的ic50。抗氧化化合物被证明是有前途的生物分子,特别是在癌症管理方面。在植物衍生物中,酚类化合物及其衍生分子具有抗氧化能力和潜在的抗增殖活性。对C4-2细胞抑制效果最好,ic50 = 65.76µg/mL,选择性指数为2.35。从这项研究中获得的结果可以部分证明这种植物治疗前列腺癌的传统适应症。

Laurus nobilis, commonly known as bay, is used in folk medicine as a remedy for many ailments. The present study investigates the protective effect of L. nobilis leaves extract against high fat diet-induced type 2 diabetes in rats. Animals were divided into group 1 (control), groups 2, 3, and 4 (bay leaves aqueous (AQ) extracts; 50, 100, and 250 mg/kg of body weight, respectively), and groups 5, 6, and 7 (bay leaves methanol/acetone (MeAc) extract; 50, 100, and 250 mg/kg of body weight, respectively). Animals were fed an isocaloric high fat diet for four weeks. The intake of bay leaves extracts was associated with a significant decreases in serum levels of glucose (AQ, 100 and 250 mg/kg; MeAc, 50, 100, and 250 mg/kg) and serum triglyceride (AQ, 250 mg/kg; MeAc, 100, and 250 mg/kg) as well as lower abdominal fat (all AQ and MeAc groups) and body weight gain (MeAc groups only). In conclusion, L. nobilis leaves extract intake provides a protective remedy against high fat diet-induced type 2 diabetes.  Key words: Laurus nobilis, type 2 diabetes, bay leaves, high fat diet.
