Effect of Different Extracts of Smilax China L. on the Activity of Ovarian Cancer Cells / 中国药师

ABSTRACT

Objective: To investigate the effects of different extracts of Smilax china L on the activity of ovarian cancer cells. Methods:Solvent extraction method was used to extract the active ingredients of Smilax china L. , and CCK-8 assay method was ap-plied to detect the influence of different Smilax china L. extracts (0, 50, 100, 150 and 200μg·ml-1 ) on the survival rate of ovarian cancer cells including low invasiveness A2780 cells and high invasiveness HO-8910PM cells. At the same time, the status of the two kinds of ovarian cancer cells at different time points (24, 48 and 72 h) was observed. Results:The IC50 of N-butanol extracts (SCR-B) on HO-8910 and A2780 ovarian cancer cells was 47. 5 μg· ml-1 and 69. 2 μg· ml-1 , respectively, and that of ethyl acetate ex-tracts (SCR-E) on A2780 and HO-8910 cells was 147. 9 μg· ml-1 and 166. 0 μg· ml-1, respectively. Smilax china L. extracts had the inhibition against both A278 and HO-8910PM ovarian cells in a dose-and time-dependent manner. Conclusion:The inhibitory activity of SCR-B against ovarian cancer cells is stronger than that of SCR-E, and SCR-B has stronger inhibition against A2780 cells than against HO-8910 cells. SCR-B has better inhibition against ovarian cancer cells.
