Phytochemical, antioxidant capacity and antifungal property screening of passiflora edulis seed ethanolic extract

Passion fruit seeds are byproduct from juice production and abundant in nutritional and health benefits. The objective of this study was to evaluate total phenolic content (TPC), antioxidant capacity and antifungal activities of ethanolic extract of passion fruit seeds. The seeds were grounded and extracted with 50% and 70% ethanol. The TPC was evaluated by Folin-Ciocalteau assay. Antioxidant capacities were measured by free radical scavenging activity (DPPH; 2,2-diphenyl-1-picrylhydrazyl), ferric reducing antioxidant power (FRAP) and antifungal acvity against Aspergillus niger using the radial growth technique. Results showed that the TPC and antioxidant capacities of the crude extraction using 70% ethanol are significantly higher than that of the 50% ethanol. Moreover, the ethanolic extract of P.edulis seed cake showed antifungal activities against important fungal foodborne pathogen ( Aspergillus niger). Conversely, the concentration of the solvent did not influence the crude yield. These findings demonstrated that the 70% ethanol would be an appropriate concentration for extraction of passion fruit seeds. However, further investigation is recommended using higher concentration of ethanol and other solvents to maximize the nutritional value of passion fruit seed.
