Investigation of Antioxidant and Antibacterial Properties of Leaf, Root, Fruit and Stem Extracts of Trichopus zeylanicus from South India

Abstract

Objective: To investigate the total phenols, flavonoids and carotenoids content, antioxidant and antibacterial potential profile of leaf, root, fruit and stem extracts of the Trichopus zeylanicus with five major solvents, that is, water, methanol, chloroform, ethyl acetate, and petroleum ether. Results: The total phenols, flavonoids and carotenoids contents of fruit methanol extract of T.zeylanicus was found to be 85.15±0.223 mg catechol equivalent per gram, 165.5622±1.236 mg quercetin equivalent per gram and 84.47273 ±0.531 mg β-Carotein equivalent per gram respectively which are higher than the activity of other extracts. The methanol extracts showed more reducing power, metal chelating activity, hydrogen peroxide scavenging and phosphomolybdenum assays than other extracts and their activity increased with increasing concentration of extracts. The hydroxyl radical scavenging activity of fruit methanol extract is quite comparable to the standard mannitol of the assay and its antibacterial potential is the best way to cope with infectious action of bacteria. Conclusion: The remarkable activity showed by the plant extracts could be attributed to the synergic effect of the active compounds present in it. Among the extracts, methanol was found to be the better solvent to extract natural products to get maximum medicinal benefits.
