Antitumor effects of extract from Ligia exotica(Roux) / 中国海洋药物

ABSTRACT

Objective To study the antitumor activities of extract from Ligia exotica(Roux).Methods The dried powder of total Ligia exotica(Roux) was extracted by 37 ℃ water.The solution was concentrated in vacuum,and then was freeze-dried to afford crude extract.The inhibitory effect of the extract on tumor cells proliferation was assayed by MTT method,and transplant tumor model of sarcoma 180(S180) was used.Results The extract from Ligia exotica displayed obvious proliferation inhibitory effect on HeLa,7901,NCI cells,and no growth inhibitory effect on 929 cells in vitro.After administration at the doses of 0.25,0.50,1.00 g?kg-1,ip,for 7d in tumor-bearing mice with S180,The extract caused 26.9 %,45.3 %,64.6 % inhibition rates,respectively.Conclusion The extract from Ligia exotica showed significant antitumor activity.
