Phenolic glycosides from the aerial parts of Buddleja macrostachya Benth.

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 .
