We investigated the cytotoxicity effects of Lycii fructus (LF) on HePG2, MCF7 and C6 cell lines by the MTT assay. We extracted the methanol (LFM) and fractionated to five partition layers. Among partition layers, the ethylether partition layer (LFMEE) was showed the strongest cytotoxic effects on all cancer cell lines. The hexane partition layer (LFMH) also was showed significant cytotoxic activities on Hela and MCF-7 cell lines. We also determined the induction of intracellular quinone reductase (QR) activity on HepG2 cells. Among various partition layers of Lycii fructus; LFMH was showed the most effective such induced effect such as 1.85 to the control value of 1.0. And we also determined the enhancement of anticarcinogenic effect by combination of Lycii fructus with vitamin C on all cell lines. These results suggest that potentially useful anticarcinegenic chemicals could be isolated from LFMEE and LFMH of the Lycii frutus and also we found the enhanced effect by the combination of various partition layers of LFM with vitamin C.
