Phytochemical study on ethyl acetate fraction of Lepidium obtusum Basin.

Three undescribed compounds (1-3), including two butenolides and one indol alkaloids. Together with twenty-one known compounds (4-24) were isolated and identified from Lepidium obtusum Basin. Their structures were elucidated by spectroscopic analysis and ECD calculations.

Two new glucoside derivatives of truxinic and cinnamic acids from mill.

A phytochemical investigations on the -butanol fraction of Mill. residues resulted in the isolation of ten compounds, including two new ones, 4,4'dimethoxy-2,2'di---d-glucopyranosyl-truxinate () and 2-(-d-glucosyloxy)--cinnamic acid butyl ester (), along with eight known compounds. The structures of compounds were confirmed by NMR and HR-ESI-MS techniques and comparison with published data.
