Cancer still remains leading cause of deaths in the world. Traditional plants are valuable source of
novel cytotoxic agents and are still playing greater role in health care. Chloroform, butanol and ethyl
acetate extracts of Symplocos racemosa bark were prepared and their cytotoxic activity determined using
the MTT salt based cytotoxicity assay in 96- micro plate format against three cancers and one normal cell
line. Cyclophosphamide was used as positive control. Absorbance was measured after 48 h at 450 nm. Of
total 3 extracts evaluated, butanolic and ethyl acetate extracts demonstrated strong cytotoxic potential
overall. Assay showed dose depended inhibition of cell growth. Butanolic extract was displayed
cytotoxicity against HL 60(Human leukemia cell line, IC50=13058 ng/ml), HeLa(Human cervix cancer
cell line, IC50=17155 ng/ml), U-937(Human myeloid lymphoma cancer cell line, IC50=16493 ng/ml), and
HEK 293T(Normal human erythrocyte kidney cell line, IC50= 31579 ng/ml) Ethyl acetate extract
displayed cytotoxicity against HL60 (IC50=206157 ng/ml), HeLa(IC50=47785 ng/ml) and
HEK293T(IC50=267116 ng/ml), and U-937 (IC50=31095 ng/ml). Chloroform extract was inactive against
all four cell lies.
