摘要
Two new benzophenone glucosides were isolated from the 60% ethanol extract of the dried stems of Cratoxylum cochinchinense. The structures were elucidated as 3-O-β-D-glucopyranosyl-2＇,4,6＇-trihydroxy-benzophenone and 3-O-β-D-glucopyranosyl-2＇,5,6＇- trihydroxybenzophenone on the basis of spectral and chemical methods.
