BACKGROUND
Portulaca oleracea Linn. (Portulacaceae) is commonly known as purslane in English. In traditional system it is used to cure diarrhea, dysentery, leprosy, ulcers, asthma, and piles, reduce small tumors and inflammations.
OBJECTIVE
To assess cytotoxic potential of chloroform extract of P. oleracea whole plant against human colon adenocarcinoma (HCT-15) and normal (Vero) cell line.
METHODS
Characterization of chloroform extract of P. oleracea by Fourier transform infrared (FTIR) spectroscopy was performed. Cytotoxicity (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay was used for assessment of cytotoxic potential of chloroform extract of P. oleracea. The concentrations of 1000-0.05 μg/ml were used in the experiment. Doxorubicin was considered as standard reference drug.
RESULTS
FTIR spectrum showed the peak at 1019.52 and 1396.21 center. The 50% cell growth inhibition (IC50) of chloroform extract of P. oleracea and doxorubicin was 1132.02 μg/ml and 460.13 μg/ml against human colon adenocarcinoma and 767.60 μg/ml and 2392.71 μg/ml against Vero cell line, respectively.
CONCLUSIONS
Chloroform extract of P. oleracea whole plant was less efficient or does not have cytotoxic activity against human colon adenocarcinoma cell line. It was not safe to normal Vero cell line. But, there is a need to isolate, identify, and confirm the phytoconstituents present in extract by sophisticated analytical techniques.
