摘要:
Three new compounds, 4-{erythro-2-[3-(4-hydroxyl-3-methoxyphenyl)-3-O-??-D-glucopyranosyl-propan-1-ol]}-O-medioresinol (1), (7???E,9???E,1???R*,3???S*,5???R*,6???S*)-5-O-caffeoyl-3-O-dihydrophaseicoylquinic acid (2), and (7???E,9???E,1???R*,3???S*,5???R*,6???S*)-5-O-caffeoyl-4-O-dihydrophaseicoylquinic acid (3), were isolated from Chinese folk herb Erycibe obtusifolia together with six known compounds (4??“9). Their structures were elucidated on the basis of comparisons of literatures and extensive spectroscopic analysis, including UV, IR, HRMS, and 1D and 2D NMR techniques. Further, the cytotoxicities of these compounds were evaluated against five cell lines (HCT-8, Bel-7402, BGC-823, A549, and A2780), but they were inactive against these tumor cell lines (IC
