| Summary: | ABSTRACT: Passion fruit Passiflora elegans (P. elegans) is an abundant and underused species present in South America, with few studies on its phytochemical composition and bioactive potential. The objective of this research was to evaluate the composition of volatiles present in P. elegans leaves by gas chromatography and mass spectroscopy, as well as to determine the antioxidant potential of the leaves and their behavior by in vitro gastrointestinal digestion. In total, 13 volatile compounds were identified. The main component found in percentage of area was (R)- (-)-(Z)-14-methyl-8-hexadecen-1-ol, followed by hexadecanoic acid, tert butyldimethylsilyl ester and 9-eicosyne. Regarding antioxidant potential, extraction with water was more effective in obtaining an extract rich in phenolics and with antioxidant potential compared to methanolic and ethanolic extraction. In vitro gastrointestinal digestion did not alter the stability of phenolic compounds, and increased the antioxidant potential by 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) test. Concluding, the volatile composition of P. elegans evidenced presence of compounds with promising bioactive potential. In addition, the aqueous extract of P. elegans leaves has excellent potential for application in bioassays and nutraceutical or food formulations, and more phytochemical and bioactive informations should be sought in the future. |
