Abstract

A new phenolic glycoside, sinapic acid 4-O-beta-d-(6'-sinapoyl)glucopyranoside (1) and a new sucrose ester, 6,6'-di-O-sinapoylsurcose (3), were isolated from the roots of Cynanchum amplexicaule (Sieb. et Zucc.), along with two known compounds, 6-O-[E]-sinapoyl-d-glucopyranoside (2) and sibricose A1 (4). Their structures were elucidated on the basis of both chemical and spectroscopic methods.

Abstract

Four new dammarane-type triterpene saponins, 1-4, were isolated from the aerial parts of Gynostemma pentaphyllum (Thunb.) Makino. Their structural elucidations were accomplished mainly on the basis of spectroscopic methods, such as IR, HR-TOF-MS, and NMR. Compounds 1-4 showed moderate cytotoxic activities against cancer cell lines HL-60, Colon205, and Du145 in vitro. [ABSTRACT FROM AUTHOR]
