Sequential separation process of antioxidant polyphenols from umbu-cajá (Spondias bahiensis P. Carvalho, Van den Berg & M. Machado) leaves by ultrasound-assisted pressurized liquid extraction

Abstract The present study aimed to evaluate the effects of ultrasound-assisted pressurized liquid extraction (UAPLE) to obtain phenolic compounds from umbu-cajá leaves using solvents with distinct polarity. Based on the results of only one-step extraction with hexane, ethyl acet...
