摘要

A new dihydroflavone, 2()-isookanin-4'-methoxy-8----glucopyranoside (), and a new polyacetylene glucoside, (10)-tridecane-2-ene-4,6,8-triyne-1-ol-10----glucopyranoside (), along with seven known compounds (), were isolated from the herb of Willd. The structures of all the extracted compounds were elucidated by HR-ESI-MS, 1 D and 2 D NMR spectra, as well as circular dichroism (CD).
