Two new phenolic glycosides from the stem of Zanthoxylum armatum DC.
Two new phenolic glycoside, 2-methoxy-4-hydroxylphenyl-1-O-α-L-rhamnopyranosyl- (1″ → 6')-β-D-glucopyranoside. (1) and threo-3-methoxy-5-hydroxy-phenylpropanetriol-8-O-β-D-glucopyranoside (2), were isolated from the stems of Zanthoxylum armatum. The compounds 1 and 2 showed weak scavenging activity in DPPH free radical assay with IC50values of 323 and 114 mM, respectively.
