Studies on Anti-tumor Activity of Crude Drugs. I. The Effects of Aqueous Extracts of Some Crude Drugs in Shortterm Screening Test. (1)

Abstract

Experiments by in vitro screening test were made concerning many kinds of crude drugs, to determine anti-tumor activity in tissue cultured cell lines, such as human cancer cell (JTC-26) and a human normal embryonic cell (HE-1) lines. Consequently a group with high selective toxicity, in which the crude extracts of some traditional drugs inhibited the growth of the cancer cells in 500-120 μg/ml, but not normal cells, was shown.
