C-glycosyl flavones in <em>Passiflora incarnata</em>

Brazil has a diversity of plant species and many them are medicinal plants used in the production herbal medicines. Passiflora incarnata is popularly known as passion fruit, its fruits aerial parts have anxiolytic sedative properties. Recent studies shown that P. several bioactive compounds such indole alkaloids, cyanogenic glycosides, maltol flavonoids. Among substances identified species, vitexin action on Central Nervous System, interfering with functioning gamma-aminobutyric acid. Thus, objective study was to identify quantify present ethyl acetate fraction fruit. For this, were submitted extraction ethanol, followed by fractionation organic solvents, obtaining hexane, dichloromethane fractions. The presence verified Thin Layer Chromatography (TLC) total flavonoid content colorimetric reaction spectrophotometer. quantification performed High Performance Liquid (HPLC). 5.34 mg/g 960 µg/g fraction. Studies like this contribute development new pharmaceutical formulations from substance vitexin.
