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

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.
