| Popis: | ABSTRACT The aim of this study was to obtain extracts from soursop pulp that were obtained with different solvents (chloroform, methanol, ethyl acetate and water) and different extraction methods (soxhlet, sonication and microwave), and analysed their extractable polyphenol content, antioxidant capacity and qualitative presence of acetogenins. The most efficient extraction method to obtain extractable polyphenols with high values of scavenging capacity by DPPH was sonication followed by microwave when methanol was used. The acetogenins were detected only in chloroform and ethyl acetate extracts obtained by the three extraction methods. Sonication or microwave was effective to obtain acetogenins or phenolic extracts in greater quantity than reported in soursop pulp, in a short time and few solvent. |
