Phenolic glycosides from the aerial parts of Buddleja macrostachya Benth.

Abstract

From the aerial parts of Buddleja macrostachya eight compounds, including: salidroside (1), echipuroside A (2), darendoside A (3), decaffeoylacteoside (4), 9-O- α -L-rhamnopyranosyl-4-hydroxy-cinnamic acid (5), 8-hydroxylinalool 3-O- β -D-glucopyranoside (6), acteoside (7), and martynoside (8) were isolated. Their Chemical structures were identified by NMR and MS spectroscopic analysis combined with a comparison to the reported values in the literature. This is the first time to report the isolation of echipuroside A, darendoside A, decaffeoylacteoside 9-O- α -L-rhamnopyranosyl-4-hydroxy-cinnamic acid, and 8-hydroxylinalool 3-O- β -D-glucopyranoside from the genus Buddleja.
