BUMALDOSIDES A, B AND C FROM THE LEAVES OF STAPHYLEA BUMALDA

摘要

Two new aliphatic diglycosides and a phenolic glucoside (4, 5 and 7) have been isolated from leaves of Staphylea bumalda DC, together with three known compounds, benzyl and phenethyl alcohol glycosides (1 and 2), and zingerone β-D-glucopyranoside (6). 2-Ethyl-3-methylmaleimide N-glucopyran-oside (3) was first isolated as a free form. Their structures were determined on the basis of spectroscopic analysis.
