Abstract

The effect of garlic extract and vitamin C mixture on the various cancer cell lines in vitro and in vivo have been examined. Proliferation of human colon cancer (HT-29), human rectal cancer (HRT-18) and human hepatoma (HepG2) cells was inhibited by garlic extract and vitamin C, respectively. Based on the cytotoxic activity, mixture of garlic extract and vitamin C was demonstrated to possess a synergistic growth inhibition on HT-29, HRT-18 and HepG2 cancer cells. Mixture of garlic extract and vitamin C significantly arrested G2/M phase cells in the HepG2 cell cycle. Oral administration of mixture of garlic extract and vitamin C to sarcoma-180 tumor-bearing mice prolonged survival time compared to that of control group. These results suggested that addition of vitamin C enhances anticancer activity of garlic extract in vitro, and mixture of garlic extract and vitamin C has antitumor effect in vivo.
