摘要：

The structures of two new flavonoid triglycosides isolated from leaves of Buddleja madagascariensis have been established as hesperetin and diosmetin 7-O (2",6"-di-O-alpha-L-rhamnopyranosyl)-beta-D-glucopyranosides using mass and NMR spectroscopy. Scutellarein 7-glucoside is reported from this plant for the first time. (C) 1998 Elsevier Science Ltd. All rights reserved.
