Abstract

WONDRACEK, Daniele Cristina et al. Saponification influence in carotenoid determination in cerrado passion fruit. Quím. Nova [online]. 2012, vol.35, n.1, pp.180-184. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422012000100031.

This work describes the evaluation of the effect of saponification process in the carotenoid's content of three species of passion fruit. The results indicated the saponification of the extract was necessary to obtain cis-violaxanthin, trans-violaxanthin and β-cryptoxanthin hydrolyzed. These compounds were found in fruits of commercial P. edulis and yellow wild P. edulis. However, the extract saponification did not permitted to obtain free carotenes in fruits of wild purple P. edulis and P. setacea, and to trans-violaxanthin of P. cincinnata, therefore saponification was not indicated in the carotenoid analysis of these three accessions of passion fruit.

Keywords : Passiflora; carotenoids, passion fruit.
