Abstract
The cellular growth inhibition of 20 natural products was screened using SRB (sulforhodamine B) assay against 4 human cancer cell lines(SNU-1, SNU-C$_{4}$, Hep3B, Kato III). Ethanol extracts of Salvia miltiorrhiza, Saussurea lappa and Chelidonium majus showed potent anticancer activity among them, and further, it was fractionated into methylene chloride, hexane and methanol. Methylene chloride and methanol fraction of Salvia radix showed significant inhibitory activity against 4 human cancer cell lines. The effect of Salvia miltiorrhiza on anticancer activity in vitro models was evaluated with methylene chloride fraction of Salvia miltiorrhiza. Life span of ICR mice implanted with sarcoma-180 was increased by 40-61% and BDF$^{1}$ mice implanted with L1210 was increased by 66-89% upon intraperitoneal administration with methylene chloride fraction of Salvia miltiorrhiza. Based on these result, we suggested that Salvia miltiorrhiza showed anticancer activity on the in vivo and in vitro models
