Compounds from the Petroleum Ether Extract of with Cytotoxic, Anticholinesterase, Antioxidant, and Antimicrobial Activities.

is a folk medicine used in many Asian countries to treat various ailments. Earlier investigations reported that the petroleum ether extract of the plant has potential biological activity, but the compounds responsible for activity are not yet completely known. Therefore, the current work was designed to isolate and characterize the compounds from the petroleum ether extract and to study their bioactivities.

Isolation of two new triterpene glycoside from the fruits of and their and studies.

Two new triterpene glycoside, Arjunoglycoside VI and Arjunursglycoside I alone with five previously known analogues were isolated from methanolic extract of the fruits of . The structures were elucidated by extensive spectroscopic studies (1 D and 2 D NMR and mass). Compound and showed moderate activity on α-chymotrypsin enzyme inhibition with IC values 53.

Evaluation of cholinesterase inhibitory and antioxidant activity of Wedelia chinensis and isolation of apigenin as an active compound.

Background: Wedelia chinensis has been reported as a folk medicine for the treatment of different diseases including neurodegenerative disease. Although the plant has been studied well for diverse biological activities, the effect of this plant in neurological disorder is largely unknown. The present study was undertaken to evaluate the cholinesterase inhibitory and antioxidant potential of W.

New ursane triterpene from the fruits of Terminalia arjuna.

A new ursane triterpene, torment (2 alpha,3 beta,19 alpha-trihydroxyurs-12-en) (1), was isolated from the fruits of Terminalia arjuna along with four known ursane and oleane triterpenes. The structures were established on the basis of extensive NMR (1D & 2D) and MS (EI & ESI) studies. Tormentic acid (2), 19 alpha-hydroxy asiatic acid (3) and olean-12-en-2 alpha,3 beta-diol (4) were isolated for the first time from this species.
