Objective: To study changes of NF-κB activity in colon carcinoma cell lines treated with different crude extracts of abrotani herba obtained through solvent extraction methods. Methods: Crude extracts of abrotani herba were extracted with ligarine, chloroform, acetoacetate and n-butanol in separating funnel. Exposure concentration of crude extracts were obtained through detecting viability of HT-29 cells by MTT. Then HT-29 cells and Lovo cells were treated with different crude extracts respectively. Changes of NF-κB activity in HT-29 cells and Lovo cells using different crude extracts were observed by EMSA. Results: Successfully extracted different crude extracts of abrotani herba and called them ligarine extract, chloroform extract, acetoacetate extract, n-butanol extract and remaining extract for short. NF-κB activity was significantly inhibited in HT-29 cells treated with chloroform extract, there were no significant differences in other groups compared with the control. The same change of NF-κB activity was observed in Lovo cells using different crude extracts of abrotani herba. Conclusion: NF-κB activity can be inhibited in colon carcinoma HT-29 cells and Lovo cells treated with chloroform extract obtained from abrotani herba through the method of solvent extraction. 展开更多
