Effect crude aquatic extract of leaves Ocimum basilicum on caner and normal cell lines in vitro

Abstract

Leaves of Ocimum basilicum were extracted with distilled water to prepare aquatic crude extract, five concentration from this extract (1000, 500, 250, 125, 62.5)µg/ml were used to study the effect of extract on cancer cell lines(Larynex carcinoma hep-2, cervix carcinoma Hela and mammary gland adenocarcinoma AMN-3) and the time exposure 24 and 48 hours as well as the effect of aquous extract on normal cell line for embryonic mice fibroblast(MEF) was studied in vitro at 48hrs. exposure. The result showed that aqueous crude extract of Ocimum basilicum leaves has different effects on cancer cell lines with significante p<0.05 the high concentration 1000 µg/ml has more inhibitory effect on cancer cell line Hep-2 compared with low concentration at 24and 48 hrs.while the Hela cancer cell line has hormetic effect which recognized by contrast in low concentration inhibitory effect as compared with high concentration at 24 and 48 hr.that low ones inhibit cell proliferation while in high ones cell proliferation continue, but AMN-3 cancer cell line more affected by low concentrations from high concentrations. Normal cell line show no significant effect for all concentrations used of aquatic crude extract of Ocimum basilicum leaf except 62.5 µg/ml with high cell inhibition 16%.
