[Studies on the chemical constituents of Carduus crispus L]
Objective:
To study the chemical constituents of Carduus crispus.
Method:
Using chromatographic methods to isolate compounds and using chemical and spectral methods to elucidate the structures of the isolated compounds.
Result:
Eight compounds were elucidated as beta-amyrin palmitate, taraxastery acetate, luteolin-7-O-alpha-L-rhamanopyranosyl-(1-->2)-beta-D-glucopyranoside, luteolin-7-O-beta-D-glucopyranoside, triacontanic acid, beta-sitosterol, stigmasterol and stigmast-7-en-3 beta-ol.
Conclusion:
All the compounds were obtained from this plant for the first time.
