Abstract: 

Prunus nepalensis (L.), locally known as Sohiong, is an important indigenous plant in Meghalaya, India. The plant has been underutilized besides having high nutritive value. The present investigation was carried out with the objective to valorize different parts of P. nepalensis as natural sources of antioxidants and antibacterial agents for food and pharmaceutical industry. Fruit, leaf, stem and seed extracts of P. nepalensis were prepared in aqueous and organic solvents (methanol, ethanol and acetone) and analyzed for phytochemical screening and in vitro antioxidant activity. The antibacterial activity of the extracts was performed using agar well diffusion method. Results confirm the presence of alkaloids, flavonoids, tannins and others phytochemicals in different extracts obtained. Ethanolic leaf extract revealed highest TPC (803.43 ± 7.76 mg GAE/ 100g DM). Methanolic leaf and stem extracts exhibited the highest radical scavenging activity (16.565 ± 0.334 and 16.679 ± 0.371 mg AEAC/g DM, respectively) whereas aqueous extract of fruit exhibited highest FRAP value (21.593±0.914 mmol AEAC/ 100g DM). Agar well diffusion test revealed good antibacterial activity of the extracts. Our findings suggest that P. nepalensis have great potential therapeutic values that need to be fully exploited.
