Phenolic glucosides from Oxytropis myriophylla.

Three phenolic glucosides were isolated from Oxytropis myriophylla. On the basis of spectral analyses, their structures were elucidated as 2-methoxy-4-(3'-hydroxy-n-butyl)-phenol-1-O-beta-D-glucopyranoside (1), syringin (2), 2-methoxy-4-(3'-hydroxy-propenyl)-phenol-1-O-beta-D-glucopyranoside (3). Compound (1) is a new phenolic glucoside named myriophylloside A, the other two compounds are isolated from this plant for the first time.
