SABOGAL-PALMA, Angie C et al. Biological characteristics of Passiflora maliformis from South Colombian Massif. Bioagro [online]. 2016, vol.28, n.1, pp.003-012. ISSN 1316-3361.

This study set out to recognize and evaluate the chemical and biological characteristics of the seeds, pulp (aryl) and peel (pericarp) of Passiflora maliformis (cholupa) from the South Colombian Massif, thus contributing to the determination of their bioactive and/or agro-industrial potential, in comparison to Passiflora edulis var. Flavicarpa (passion fruit). The fruits were obtained in the Municipality of Rivera-Huila, and their initial phytochemical analysis showed abundant content of tannins, anthocyanic pigments, and nature terpene constituents. When evaluating the antioxidant functionality it was found that the compounds of the peel and seed of cholupa have a slight ability to scavenge free radicals and block the oxidation chain, ability that increased as extract concentration increased, reaching the maximum capacity in a time of 6 to 11 minutes. It was revealed an important antimicrobial activity of the fruit ethanolic extracts which was maximum at the concentration of 10,000 µg·mL^-1, and responds to the abundance of secondary metabolites and other bioactive compounds and shows the cholupa with high bacteriostatic potential, being the seed the part with greater activity. The bacterium Klebsiella pneumoniae was the most sensitive strain to the action of the compounds present in the fruit. Not even at their maximum concentrations, products derived from peel and seed of P. maliformis exceeded 10 % toxicity in humans.
