Evaluation of nutritive value, phytochemical screening, total phenolic content and in-vitro antioxidant activity of the seed of Prunus domestica L.

Prunus domestica L. is a member of the Rosaceae family that shows many biological activities including antioxidant, antimicrobial, antihaemolytic, anti-inflammatory, hepatoprotective activity and many other activities. In the current study, we evaluated nutritive value, phytochemical screening, total phenolic content and antioxidant activity by DPPH and FRAP method for the different extracts obtained by successive soxhlet extraction using the different solvents based on their polarity. Results show that it is a good source of energy. Phytochemical screening revealed the presence of many secondary metabolites which include alkaloids, carbohydrates, glycosides, protein, steroids and terpenoids, fixed oils and fat as well as phenolic compounds. The highest total phenolic content was found in the ethyl acetate fraction. Highest antioxidant activity by DPPH method is reported in ethyl acetate fraction (IC50 =1837.399±0.377µg/ml) while the ferric reducing antioxidant power was maximum for diethyl ether (56.032±0.985µM/ml FRAP value = 0.325±0.002)
