The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhibition of cell growth in the hepatoma cell line and the cytopathological changes were studied. GC-MS analysis showed the presence of fifty compounds in the methanolic extract of C. longa. The major compounds were ar-turmerone 20.50 %, β-sesquiphellandrene 5.20 % and curcumenol 5.11 %. Curcumin was identified using IR, 1H and 13C NMR. The inhibition of cell growth by curcumin IC50 = 41.69 ± 2.87 µg mL–1 was much more effective than that of methanolic extract IC50 = 196.12 ± 5.25 µg mL–1. Degenerative and apoptotic changes were more evident in curcumin-treated hepatoma cells than in those treated with the methanol extract. Antitumor potential of the methanolic extract may be attributed to the presence of sesquiterpenes and phenolic constituents including curcumin 0.051 %, 511.39 µg g–1 dried methanol extract in C. longa rhizomes.
