Two new sesquiterpenoid glycosides from the stems of Zanthoxylum armatum DC

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.
