Ultrasound-Assisted Extraction of Betalains from Opuntia Fruit Pulp of Different Color Varieties

چکیده
Betalains are water-soluble pigments that have exhibited important pharmacological properties such as antioxidant, anticancer, antilipidemic and antimicrobial activity. These compounds been isolated in numerous purple plants or fruits, is the case of wild species under Opuntia genus. The fruits these often disregarded because their small size well frequent presence prickles. Based on this, this research has its objective optimization a method based ultrasound-assisted extraction to obtain extracts enriched with betalains from (Opuntia dillenii (Ker Gawl.) Haw.). Four variables (%EtOH solvent, temperature extraction, ultrasound amplitude cycle) were selected using Box–Behnken design. quadratic interaction %EtOH %EtOH–cycle proven be influential at 95% confidence. conditions highest betalain concentration 100 mg pulp 20 mL (60%:40% EtOH:H2O) solvent °C 24% 0.2 cycle for 10 min. suitability reliability evaluated repeatability intermediate precision tests obtaining CVs <5%. Finally, developed employed analysis five commercial samples obtained significant antioxidant activity extracts, confirming applicability.
