Abstract

Two new sesquiterpenoid glycosides as dihydrophaseic acid 4'-O-[6″-O-(4″'-hydroxy-3″', 5″'-dimethoxy) benzoyl)]-β-D-glucopyranoside (1) and dihydrophaseic acid 4'-O-[6″-O-(3″'-methoxy- 4″'-hydroxy) benzoyl)]-β-D-glucopyranoside (2), were isolated from the stems of Zanthoxylum armatum in the study. The compound 1 and 2 showed moderate scavenging activity in DPPH free radical assay with IC50 values of 241 and 264 μM, respectively.

Keywords: Zanthoxylum armatum; scavenging activity in DPPH free radical; sesquiterpenoid glycoside.
