Summary

Cytotoxic Effect of Alkaloids from Euphorbia thymifolia Burm. Grown in Vietnam

From 96% ethanol extract of Euphorbia thymifolia Burm. collected in Nam Dinh province, four compounds (1-4) were isolated by various chromatographic methods. These compounds were identified as haemanthamine (1), lycorine (2), 3-epimacronine (3) and 6-O-methylpretazettine (4) by spectroscopic methods including IR, MS, and NMR. These compounds were isolated from Euphorbia thymifolia Burm. for the first time. Compounds 1 and 2 showed potential cytotoxic activity against epithelial cancer cells (KB) with IC50 values of 4.22 and 3.97 μM, respectively, and liver cancer cell lines (Hep G2) with IC50 values of 3.65 and 3.41 μM, respectively.

Keywords: Euphorbia thymifolia Burm., Euphorbiaceae, Cytotoxicity, Haemanthamine, Lycorine.
