Phenolic Constituents from Sarcopyramis Nepalensis and Their Α-glucosidase Inhibitory Activity
Background: This study was carried out to fully investigate the phenolic chemical constituents of Sarcopyramis nepalensis and determine their α-glucosidase inhibitory activity. Materials and Methods: S. nepalensis was extracted using the ultrasonic assistant extraction (UAE) method and further fractionated with petroleum ether (PE), chloroform (CHCl3), ethyl acetate (EtOAc) and n-butanol (n-BuO...
متن کاملα-Glucosidase inhibitory constituents from Acanthopanax senticosus harm leaves.
A new triterpene glycoside, 3-O-[(α-L-rhamnopyranosyl)(1→2)]-[β-D-glucuronopyranosyl-6-O-methyl ester]-olean-12-ene-28-olic acid (1) and a new indole alkaloid, 5-methoxy-2-oxoindolin-3-acetic acid methyl ester (5) were isolated from the leaves of Acanthopanax senticosus Harms along with six known compounds. The structures of the new compounds were determined by means of 2D-NMR experiments and c...
متن کاملPotential Anti-obesity Effects of some Medicinal Herb: In vitro α-Amylase, α-Glucosidase and Lipase Inhibitory Activity
In this study, in vitro inhibitory activity of methanolic and chloroform extracts of some medicinal plants including C. wightii, T. ammi, N. sativa, C. arabica, L. usitatissimum, C. cyminum, and R. Graveolens was evaluated toward α-glucosidase, α-amylase, and lipase comparing with acarbose and orlistat as the standard inhibitors. Our results revealed that both methanolic and chloroform extracts...
متن کاملAntiseptic activity and phenolic constituents of the aerial parts of Vitex negundo var. cannabifolia.
Four phenolics, salviaplebeiaside (1), γ-tocopherol (2), chrysosplenol-D (4), and isovitexin (5), along with α-tocoquinone (3) and β-sitosterol (6) were isolated from the aerial parts of Vitex negundo var. cannabifolia. The isolation was performed using bio-assay tracking experiments. The structures of compounds 1-5 were established by spectroscopic means. The antibacterial activities of the co...
متن کاملIn vitro α-amylase and α-glucosidase Inhibitory and Cytotoxic Activities of Extracts from Cissus cornifolia Planch Parts
CONTEXT Hyperglycemia is the hallmark of type 2 diabetes mellitus, and its prevention will go a long way in managing the disease and its associated complications. Reduction of postprandial hyperglycemia through retarding carbohydrates digesting enzymes is one of the major therapeutic approaches used in the management of diabetes. OBJECTIVE The aim of the present study was to investigate the a...
