ANALYSIS OF PASSION FRUIT RINDS (Passiflora edulis): ISOORIENTIN QUANTIFICATION BY HPTLC AND EVALUATION OF ANTIOXIDANT (RADICAL SCAVENGING) CAPACITY

ANALYSIS OF PASSION FRUIT RINDS (Passiflora edulis): ISOORIENTIN QUANTIFICATION BY HPTLC AND EVALUATION OF ANTIOXIDANT (RADICAL SCAVENGING) CAPACITY. The content of isoorientin in passion fruit rinds (Passiflora Mulls fo. flavicarpa O. Degener) was determined by HPTLC (high performance thin layer chromatography) with densitometric analysis. The results revealed a higher amount of isoorientin in healthy rinds of P edulis (92.275 +/- 0.610 mg L-1) than in rinds with typical symptoms of PWV (Passion fruit Woodiness Virus) infection (28.931 +/- 0.346 mg L-1). The HPTLC data, allied to assays of radical scavenging activity, suggest the potential of P Mulls rinds as a natural source of flavonoids or as a possible functional food.
