Evaluation of total phenolic content and antioxidant activity of different solvent extracts of Egyptian purslane leaves .
Abstract: Egyptian purslane (Portulaca oleracea L.) is a green plant which has been known since times of the ancient Egyptians rarely found now in Egypt. The objective of this work was carried out to evaluate the total phenolic content and antioxidant activity of different solvent extracts of Egyptian purslane leaves using different assays. Purslane leaves extracted by four different solvents: ethanol, methanol, cold water and hot water. The total phenolic and total flavonoid contents were determined in all extracts. The antioxidant activity was determined using total antioxidant capacity, reducing power, DPPH radical scavenging, nitric oxide scavenging, hydroxyl radical scavenging and Fe+2chelating activities. The results revealed that the highest amount of phenolic content was found in methanol extract (326.80±31.22 mg/g purslane leaves) while the lowest amount was found in hot water extract (228.27±58.06 mg/g purslane leaves). The purslane extracts exhibited antioxidant activity in all assays. The methanol extract possessed the highest antioxidant activity among purslane extracts could be associated with its content of phenolic compounds. The result was concluded that the purslane and purslane extracts are an excellent source of natural antioxidant, which has biological impacts on human health and could be used for food and nutraceutical applications.
