Abstract: OBJECTIVE:The aim of this study was to investigate the toxicological activityity of total flavonoids from Xinjiang semen Nigellae,the unique national drug resources of Xinjiang,in human cervical cancer cell lines to investigate the mechanism by using. METHODS:Two humna cervical carcinoma cell lines,SiHa and HeLa,were treated with different concentrations of the total flavonoids from the semen nigellae(2.5,5,10,15,20,25,50 μg/mL). Their toxicological activities were detected using the MTT assay which determined the effective concentrations and IC50. Anti-migration effects were detected by cell scratch assay. Apoptosis rates were detected by flow cytometry. RESULTS:Compared with the control group,proliferation of the treated cervical cancer cells was inhibited in a concentration-dependent manner. The IC50 of total flavonoids was 16.935 μg/mL for SiHa and 18.366 μg/mL for HeLa. By comparing the scratch widths before and after the treatments,the relative migration distance of tumor cells in the SiHa cell line control group was (223.333±13.868) px,and that in the treated group was (56.333±10.970) px. The relative migration distance of the HeLa cell control group was (360.667±15.308) px,and that in the treated group was (13.000±3.606) px. Total flavonoids also induced apoptosis in both cervical cancer cell lines. The apoptosis rates in the 10,15 and 25 μg/mL treatment groups were (8.5±0.5)%,(35.9±1.3)% and (85.7±1.6)% for SiHa,and were (5.3±0.4)%,(11.4±0.8)% and (85.9±1.9)% for HeLa. The differences were significantly different from that of the control (P < 0.05). CONCLUSION:The total flavonoids from Xinjiang semen nigellae demonstrated anti-proliferation anti-migration activities in vitro and induced apoptosis in human cervical cancer cell lines.
