Abstract

A new phenolic glycoside, tinosinen (1), was isolated from the fresh stems of Tinospora sinensis Merr. The structure was established on the basis of acid hydrolysis and spectral data (IR, NMR, mass) as (E)-1-(3-hydroxy-1-propenyl)-3,5-dimethoxyphenyl 4-O-β-D-apiofuranosyl-(1→3)-β-D-glucopyranoside.

Key words

Tinospora sinensis - Menispermaceae - phenolic glycoside - tinosinen
