Antioxidant Test, Phenolic And Flavonoid Content Ethanol Extract And Ethyl Acetate Fraction Of Purple Passion Fruit Peel (Passiflora edulis Sims.)
MetadataShow full item record
Purple passion fruit (Passiflora edulis Sims.), Passifloraceae family. In order to conduct a research for the utilization of purple passion fruit peel as an eye remedy, antioxidant test phenolic and flavonoid content to ethanol extract and ethyl acetate fraction of passion fruit (Passiflora edulis Sims.) peel should be examined. The peel of the fruits is macerated with 96% ethanol, then fractionated using ethyl acetate. Ethanol extract and ethyl acetate fraction were tested for their antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl. To determine the phenolic content and flavonoid content were calculated as Gallic Acid Equivalent (GAE) with Folin Ciocalteu and Flavonoid as Quercetin Equivalent (QE) with AlCl3 by using colorimetric method. The results showed that both ethanolic axtract and ethyl acetate fraction were had antioxidant activity and medium phenolic content and flavonoid content.
