Antioxidant Activity, Phenolic And Flavonoid Content of Passion Fruit Seed Oil

Abstract

Passion fruit (Passiflora edulis Sims.) is a tropical plant that grows widely in South East Asian region, including on Sulawesi Island. The plant is important in the food sector and for medicinal purposes. The fruits of the Passion plant are made as a popular syrup beverage in Makassar produced by several companies. The production process results in an unusable seed containing potential natural oil. Passion Seed Oil (PSO) has several benefits in health and cosmetics. The oil contains chemically active compounds such as phenolic and flavonoids with antioxidant activities. This study was performed by comparison of several solvents acetone, ethyl acetate, chloroform, methanol, and n-hexane. The antioxidant activity, total phenolic and flavonoid content of all extracts were then examined by the researchers. The potential antioxidant activity of PSO was shown by a methanol extract of 71.67 µg/mL. The highest flavonoid content was ethyl acetate extract of 35.40 mg RE/g crude extract, and phenolic was acetone extract of 193.80 mg GAE/g crude extract.
