Objective To discuss the antitumor effects of ethanol extracts from Ligularia jaluensis and Ligularia intermedia in vitro,and to provide references for the development of antitumor drugs as well as the comprehensive utilization and development of Ligularia genus resources in Changbai Mountain. Method The inhibiting effects of ethanol extracts from Ligularia jaluensis and Ligularia intermedia on the multiplications of 2 kinds of tumour cells (Hela,A549) were determined by MTT colorimetric assay in vitro. Flow cytometry was applied to test cell apoptosis. The effects of ethanol extracts from two kinds of ligularia genus plants on the clearance of Hydroxy free radical( ) and superoxide anion free radical ( O-2 · ) were measured by Phenanthroline and Pyrogallol autoxidation methods. Results The A549 and Hela cells were treated with different concentrations of the ethanol extracts for 48 hours, and the inhibition rates increased remarkably with increasing of concentration. For the clearance of ,the IC50 of FXEtOH,XBEtOH and Vc were 73. 34,335. 30 and 79. 31μg/mL,respectively. For the clearance of O-2 ·, the IC50 of FXEtOH, XBEtOH and Vc were 64. 81, 131. 89 and 191. 62 μg/mL, respectively. Conclusion Both the ethanol extracts of Ligularia jaluensis and Ligularia intermedia possess the antineoplastic activity in vitro and good comprehensive antioxidant capacity which may be one of their possible mechanism on antitumor.
