Composição de ácidos graxos e atividade antioxidante do óleo da semente da romã cv. ‘molar’.

Abstract

Since ancient times, pomegranate has been widely used as a universal therapeutic agent due to the presence of biological active ingredients in different parts of the plant. Pomegranate seed oil is considered a precious nutraceutical because of its rich composition. In this sense, the present work had as objective to study the main changes in the composition of fatty acids and antioxidant activity of the pomegranate seed oil (cv. Molar) in different stages of fruit development. The seed oil was extracted from a sample of 20 fruits at different stages of development at 60, 70, 80, 90 and 100 days counted from the start of the anthesis. When analyzing the general composition of the oil of pomegranate seeds cv. In this study, it was observed that, regardless of the stage of development of the fruit, the oil takes the order of SFA> PUFA> MUFA, with a higher content of saturated fatty acids, followed by polyunsaturated fatty acids (omega 3 and 6) and monounsaturated, and at lower concentrations of total transisomers. Regarding the composition of fatty acids in the pomegranate seed oil cv. 'Molar', it is verified that the best periods for the consumption of the oil of the pomegranate seed are between 80 and 90 days, due to the higher amount of unsaturated acids, and lower concentrations of palmitic acid. The method of DPPH, with extractor of methanol, can identify the antioxidant activity of pomegranate seed oil, however not efficiently.
