Otimização e avaliação do extrato hidroalcóolico de Schinus terebinthifolius Raddi obtido por ultrasom.

Schinus terebinthifolius Raddi is a plant family Anacardiaceae, native to Brazil. Have been isolated from this plant several secondary metabolites: terpenes, lectins, saponins, tannins, phenolics, flavonoi ds and alkaloids, responsible for various biological activities: antibacterial, antiviral, antifungal, anti - inflammatory, anticarcinogenic, antihypertensive and hypolipidemic. The objective is to evaluate and optimize the extraction conditions of active su bstances present in leaves of Schinus terebinthifolius Raddi ultrasound. The leaves of Schinus terebinthifolius Raddi (100 g) were placed in ethanol at 50, 70, 80 and 96% for extraction by ultrasound. The extracts were analyzed by GC - FID and had a higher c oncentration of α - pinene (0.0225 mL / mL) and limonene (0.1475 mL / mL) in the alcohol content of 80% and 70% respectively. These extracts were evaluated by physical - chemical parameters of pH (4.85, 4.96, 5.36 and 5.79), dry (0.0546 g, 0.0653 g, 1.2074 g a nd 1.0501 g), density (0.9253, 0.9185, 0.9037 and 0.8546) and refractive index at 20 ° C (1.3620, 1.3622, 1.3653 and 1.3657), respectively. Most obtaining the dry residue was extracted in 80% ethanol. We use this alcoholic with different proportions of the drug (10, 20 and 30%) and obtained the highest concentration of α - pinene (0.0037 mL / mL) and limonene (0.0473 mL / mL) in 30%. To optimize the extraction conducted an extraction kinetics in proportion and alcohol content for a period of 5 to 60 minutes. The best time to extract the α - pinene (0.02024 mL / mL) and limon ene (0.15911 mL / ml) was 10 minutes. Knowledge of the extraction conditions and the chemical behavior of the constituents of a plant represents a key step in the evaluation of an extract.
