Antidiabetic Potential of Roots: In Vitro Pancreatic Beta Cell Protection, Enhancement of Glucose Consumption, and Bioassay-Guided Fractionation.

By using the streptozotocin- (STZ-) induced cytotoxicity in -TC3 cells as an assay model, a bioassay-guided fractionation study was employed to isolate and characterize the potential antidiabetic principles of roots of A combination of open column chromatography on reverse-phase silica gel using a water-ethanol gradient (10 : 90 to 100 : 0) followed by HPLC-based fractionation led to an active compound that appears to be composed of carbohydrate/sugar. When cell viability under STZ was reduced to 49.8 ± 4% (mean ± SD), treatment with the active compound at the concentration of 0.

Bioassay-guided Isolation of Neuroprotective Fatty Acids from against 1-methyl-4-phenylpyridinium-induced Neurotoxicity.

Objective: Parkinson's disease, a slowly progressive neurological disease, is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine. The main aspects of researches are the protection of normal neurons against degeneration. Fatty acids (FAs), the key structural elements of dietary lipids, are carboxylic straight chains and notable parameters in nutritional and industrial usefulness of a plant.

Protective effect of bioactive compounds from against cisplatin-induced oxidative stress and apoptosis in the PC12 cell line.

Objectives: The present study aims to evaluate the protective effect of the compounds isolated from () against oxidative stress and apoptosis induced by cisplatin (CIS) in PC12 cells.

Materials And Methods: Six compounds were isolated as quercetrin-3---D-glucopyranoside (QUE), osthol (OST), verbenone-5---D-glycopyranoside (VER), Isoimperatorin (ISO), kaempferol-3---D-glucopyranoside (KAM), and echinophorin B (ECH). For this study, we used MTT reduction assay for detection of protective effects of isolated compounds on CIS-induced cytotoxicity in PC12 cells.

Ethanolic Extract of Berberis Vulgaris Fruits Inhibits the Proliferation of MCF-7 Breast Cancer Cell Line Through Induction of Apoptosis.

Background: As it is obvious, there is much documentation that shows the importance of breast cancer treatment in patients. High expressions of P53 and Bcl-2 are associated with breast cancer, which are reliable factors to follow up the breast cancer. Berberis vulgaris is used as a traditional medicine in cancer.

New polyacetylenes from Echinophora cinerea (Boiss.) Hedge et Lamond.

Echinophora cinerea aerial parts are used in folk medicine to cure gastric diseases and as a food seasoning in cheese and yogurt. Besides several pharmacological effects have been assigned to Echinophora spp., there is no phytochemical investigation on this genus other than our previous publication on flavonoids.
