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.
