Stephania delavayi Diels. (S. delavayi Diels.) has been used as a drug for pain-relieving and acute gastroenteritis treatment in China. Because the major therapeutic mechanism of anti-inflammatory drug is to inhibit the cyclooxygenase (COX)-2 and because COX-2 proteins inhibit apoptosis, COX-2 inhibitor has been thought as the anticancer drug candidate. For this reason, we examined S. delavayi Diels. as an anticancer drug. S. delavayi Diels. was fractionated with methanol and then partitioned with ethyl acetate, n-butanol and water. The antioxidant activity was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and reducing power. DPPH radical scavenging activities of the crude fractions at the concentration of 1,000 §¶/mL were 75.23% (n-butanol), 68.11% (methanol), 63.58% (ethyl acetate), and 50.13% (water). The reducing power increased according to the concentration in dose-dependent manner. Also, when the antiproliferation effects of each fraction against human breast cancer cell-lines MDA-MB-231 and MCF-7 were examined, methanol extract, n-butanol fraction and ethyl acetate fraction exhibited cell proliferative inhibition effects in both cell-lines whereas water fraction did not. Among the crude fractions, the n-butanol fraction exhibited the most potent anti-proliferation effect. In conclusion, fractions from S. delavayi Diels. are promising anticancer drug candidates.
