Eclalbasaponin I has anti-oxidative, and antitumor activities, it reduces oxidative stress-induced neural cell death by autophagy activation, it can dose-dependently inhibit the proliferation of hepatoma cell smmc-7721 with the IC(50) value of 111.1703 ug

Four fractions (water, 30% ethanol, 60% ethanol and 90% ethanol) were obtained. Four compounds, wedelolactone (I), Eclalbasaponin I (II), luteolin (III) and luteolin-7-O-glucoside (IV) were purified and their structures were identified by the interpretation of spectroscopic analyses including MS, (1)H and (13)C NMR. Antitumor activities of extracts (total fraction), four fractions and the isolated compounds were assessed using hepatoma cell smmc-7721 as an in vitro assay system. The 30% ethanol fraction and Eclalbasaponin I dose-dependently inhibited the proliferation of hepatoma cell smmc-7721 with IC(50) values of 74.2399 and 111.1703 μg/ml, respectively, more strongly compared with 5-fluorouracil positive control group with the IC(50) value of 195.3131 μg/ml. Antitumor activities of other fractions and compounds were lower than positive control.
