Tripterygium wilfordii is a medicinal plant that plays a crucial role in health care programs, especially in developing countries, and had anti-tumor, anti-inflammatory, anti-fertility, anti-bacterial, and other therapeutic effects. This study was designed to determine the anti-proliferative effects of methanolic extract of T. wilfordii on the WRL-68 cell line and the function of polycystin-1 (PC-1). The half-maximal inhibitory concentration (IC50) values were recorded in WRL-68 and AsPC-1 cell lines as 193 µg/ml and 149.2 µg/ml, respectively, at 2-2.55 and 2-2.2 µg/ml methanolic plant concentrations. The maximum cytotoxic activities of the extract on the growth inhibition of WRL-68 and AsPC-1 were generally observed at 97.64% and 95.94% at extract concentrations of 50 µg/ml and 25 µg/ml, respectively. The pharmacognostic profile of T. wilfordii extract was found to be alkaloids, tannins, terpenoides, flavonoids, glycosides, and phenols. The extracts of T. wilfordii were tested through gas chromatography-mass spectrometry showing four peaks representing mostly of 3-Oxobutanol; ethyl acetate; acetic acid ethyl ester; chlorbromuron; 1-(methylthio)-, (E)-; n-Hexadecanoic acid; tetradecanoic acid; and 9-Octadecenoic acid. Therefore, the results of this study revealed that the methanolic extract of T. wilfordii was more potential in inducing anti-proliferative activity of WRL-68 and AsPC-1 human cell lines than the control. In addition, the current study was the first study that reported the anti-proliferative potential of T. wilfordii in the treatment of human embryonic liver WRL-68 cancer cells.
