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.
