Further acylated flavonol bisdesmosides from Sinocrassula indica

Abstract

Further investigation on the whole herbs of Sinocrassula indica (Crassulaceae) led to the isolation of four new acylated flavonol bisdesmosides, sinocrassosides A₁₃ (1), B₆ (2), B₇ (3), and D₄ (4), together with kaempferol 3-O-β-d-(6-O-acetyl)glucopyranosyl-7-O-α-l-rhamnopyranoside (5). Their structures were established by spectral and chemical methods.

Keywords:
