Evaluation of Solvent Effects on NMR Metabolic Profiling of Passiflora cincinnata Mast. Cv. BRS Sertão Forte

Resumo

Passiflora cincinnata Mast. is a native species from the Caatinga biome (Brazil), commonly known as
“maracujá-do-mato” and “maracujá-da-Caatinga”. P. cincinnata leaves were subjected to microextraction
with 70% ethanol-water mixture as follows: 1.5 mL of the solvent mixture was added in 50 mg of powdered
leaves and sonicated for 15 min. After solvent removal, the samples were analyzed by nuclear magnetic
resonance (NMR). Besides signals from primary metabolites, the chemical profile revealed the presence
of isovitexin, vitexin-2”-O-xyloside, and trigonelline. Tracking these compounds might be of interest to
metabolomic studies.
