Compositional analysis and in vivo anti-diabetic activity of wild Algerian Marrubium vulgare L. infusion     

Boudjelal A  Henchiri C  Siracusa L  Sari M  Ruberto G 《Fitoterapia》2012,83(2):286-292

Marrubium vulgare (Lamiaceae) is a plant traditionally used for the treatment of diabetes in Algeria. Compositional analysis of the aqueous infusion revealed the presence of fifteen metabolites, all belonging to the class of polyphenols. Particularly, seven flavonoids have been detected, together with 5-caffeoylquinic (chlorogenic) acid in small amounts; the extract is dominated by the presence of a series of complex molecules, characterized as verbascoside (acteoside) derivatives. Concerning the anti-diabetic effectiveness a series of in vivo experiments were carried out on albinos Wistar rats. Diabetes was induced in the animals by intra-peritoneal injection of alloxane; they were treated twice a day with aqueous extract from aerial part infusion (100, 200 and 300 mg/kg body weight) and glibenclamide (5mg/kg body weight) for 15 days. Oral administration of 200 and 300 mg/kg body weight of aqueous extract the Marrubium vulgare induced an significant effect antidiabetic and antihyperlipidemic (dose-dependent effect). A decrease in blood glucose by 50% for the dose 100 mg/kg and more than 60% for doses 200 and 300 mg/kg, as well as a significant lowering of total lipids, triglycerides, and total cholesterol levels in treated animals, compared with diabetic controls group (p<0.001), have been observed. Glibenclamide was used as reference and showed similar effects.  相似文献

Chemical composition and anti-Candida potencial of the extracts of Tarenaya spinosa (Jacq.) Raf. (Cleomaceae)     

《Comparative immunology, microbiology and infectious diseases》2019

Phytochemical prospecting was performed by HPLC-DAD. The Inhibitory Concentration of 50% of mortality the microorganisms (IC₅₀) was determined and a cell viability curve was obtained. Minimum Fungicidal Concentration (MFC) was determined by subculture in Sabourad Dextrose Agar. The effect of the combination extract/fluconazole was verified by microdilution, with the extracts in subinhibitory concentrations (MFC/16). Caffeic acid was the major compound of both extracts, representing 6.08% in the aqueous extract and 7.62% in the ethanolic extract. The extracts showed a fungistatic effect (MFC ≥ 16,384 μg/mL). The IC₅₀ results demonstrated that the combination of the extracts with fluconazole were more significant than the products tested alone, with values from 4.9 to 34.8 μg/mL for the ethanolic extract/fluconazole and 5 to 84.7 μg/mL for the aqueous extract/fluconazole. The potentiating effect of fluconazole action was observed against C. albicans and C. tropicalis. In C. krusei the aqueous extract had an antagonistic effect.  相似文献

双向固体发酵后雷公藤菌质化学成分研究   总被引：4，自引：0，他引：4  

张普照  舒任庚  谢小梅 《中国食用菌》2008,27(1):41-42,47

目的：在前期药理实验基础上,分析双向性固体发酵后雷公藤菌质的化学成分。方法：采用高效液相色谱法和薄层色谱法,研究雷公藤药材和不同发酵时间药性菌质的化学成分动态变化规律。结果：药性菌质的雷公藤甲素含量低于原药材低;分别在218nm和250nm波长下,高温灭菌药材和发酵30d的药性菌质的液相图谱有3处明显的变化;乙酸乙酯提取物的薄层层析发现有一蓝色斑点为发酵后新增成分,而甲醇提取物薄层层析发现有2个斑点随发酵时间的延长含量降低。结论：雷公藤经药用真菌发酵后化学成分发生变化,其中一些化学成分的变化规律与药理实验结果存在相关性,可作为发酵终点判断标准。  相似文献
