Antiproliferative, apoptotic, and antimutagenic properties of stem bark and seed fractions of (Roxb.).

Aims: The aim was to compare the anticancer and antimutagenic potency of Polyalthia cerasoides seeds and stem bark.

Aim Of The Study: The aim of this study was to investigate the antiproliferative, apoptotic, antioxidation to DNA, and antimutagenic activity of alcoholic (PS-1 and PS-3) and petroleum ether (PS-2 and PS-4) stem bark and seed fractions of P. cerasoides.

Methods: P. cerasoides stem bark and seeds were extracted with ethanol: water mixture (9:1 ratio v: v) and fractionated with petroleum ether. Fractions were investigated for antiproliferative effect using cell by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide, a tetrazole assay (cell line used liver [HepG2] and cervical [HeLa] cancer cell lines), DNA damage protection using hydroxyl radical and antimutagenic effect using chromosome aberration test.

Results: PS-1 (IC50 10 μg/ml) and PS-3 (IC50 11 μg/ml) showed maximum antiproliferative activity against HepG2 cell lines, whereas, PS-1 (IC50 10 μg/ml), PS-2 (IC50 24 μg/ml), and PS-3 (IC50 11 μg/ml) showed better antiproliferative activity against HeLa cell lines. PS-3 and PS-4 were protective against oxidation to the supercoiled DNA molecule. Further, petroleum ether extract of both seed (PS-2) and stem bark (PS-4) showed good antimutagenicity as revealed by the less chromosomal aberrations compared to PS-1 and PS-3 fractions.

Conclusions: This study demonstrated the beneficial effect of fractions against oxidation of DNA, antiproliferative, apoptotic, and antimutagenic activity. Probably, this property would be attributable by their phenolic and steroid constituents. Therefore, this plant could be used as a potential source of nutraceutical agents.
