Fitoconstituintes isolados da fração em diclorometano das cascas do tronco de Scutia buxifolia Reissek

Fracionamento cromatográfico da fração em diclorometano obtida do extrato etanólico das cascas do tronco de Scutia buxifolia Reissek (Rhamnaceae) conduziu ao isolamento de lupeol, β-sitosterol e estigmasterol. As estruturas foram identificadas através de técnicas espectroscópicas usuais, além da comparação com dados relatados na literatura. Os compostos isolados são relatados pela primeira vez para a espécie S. buxifolia.Fractionation of the dichloromethane soluble fraction from the ethanol extract of the stem bark of Scutia buxifolia Reissek (Rhamnaceae) led to the isolation of lupeol, β-sitosterol and stigmasterol. The structures of the isolates were elucidated by spectroscopic analysis and comparison with literature data. The isolated compounds are reported for the first time to the species S. buxifolia.Colegio de Farmacéuticos de la Provincia de Buenos Aire

HPLC analysis and phytoconstituents isolated from ethyl acetate fraction of Scutia buxifolia Reiss. Leaves

Fractionation of the ethyl acetate soluble fraction from the ethanol extract of the leaves of Scutia buxifolia (Rhamnaceae) led to the isolation of quercetin, quercetin 3-0-rhamnoside (quercitrin), quercetin 3-0-glucoside (isoquercitrin) and rutin. The structures of the isolates were elucidated by spectroscopic analysis and comparison with literature data and analyzed for high performance liquid chromatography (HPLC). The isolated compounds are reported for the first time to the species S. buxifolia.Colegio de Farmacéuticos de la Provincia de Buenos Aire
