인체암세포주에 대한 천연자원의 세포독성 검색 (I)

For the search of new antineoplastic agents from natural resources, two hudred and one kinds of oriental medicinal drugs were extracted with petroleum ether/ether(1:1), ethyl acetate and methyl alcohol, successively and their cytotoxicities were evaluated against A549 (human lung carcinoma) and SK-OV-3 (human ovary adenocarcinoma) cell lines. Among them, thirty kinds of ether extracts, forty-one kinds of ethyl acetate extracts and nine kinds of methanol extracts showed significant cytotoxic activities (above 70% inhibition) against A549 cell lines at a concentration of $40\;{\mu}g/ml$. And also, twenty-four kinds of ether extracts, thirty-one kinds of ethyl acetate extracts and six kinds of methanol extracts showed significant cytotoxic activities against SK-OV-3 cell lines at the same concentration.
