概要
OBJECTIVE
To study the chemical constituents of Chondrilla piptocoma.
METHODS
The chemical constituents were isolated and repeatedly purified on silica gel column and the structures were elucidated by the NMR spectra and physico-chemical properties.
RESULTS
Seven compounds were obtained and they are identified as luteolin, 5,7,4'-trihydroxy-3'-methoxy flavone, luteolin-7-O-beta-D-glucoside, apigenin, beta-sitosterol, stigmasterol, ursolic acid.
CONCLUSIONS
All the compounds were obtained from C. piptocoma for the first time.
