Further acylated flavonol bisdesmosides fromSinocrassula indica
摘要:
Further investigation on the whole herbs of Sinocrassula indica (Crassulaceae) led to the isolation of four new acylated flavonol bisdesmosides, sinocrassosides A(13) (1), B-6 (2), B-7 (3), and D-4 (4), together with kaempferol 3-O--d-(6-O-acetyl)glucopyranosyl-7-O--l-rhamnopyranoside (5). Their structures were established by spectral and chemical methods.
