摘要

Buritirana (Mauritiella armata) is a palm tree belonging to the Aceraceae family, which, despite being little explored, presents unique sensorial, chemical, and nutritional characteristics. In this study, supercritical fluid extraction (SFE), pressurized liquid extraction (PLE), 70% ethanol (70:30 v/v), and subcritical water extraction (SWE) using a single step and a sequential process (SFE → PLE → SWE) were used for obtaining extracts from buritirana pulp. These extractions were compared to Soxhlet-hexane. The kinetic and extraction yield were obtained for SFE, PLE, and SWE. The composition and quality of buritirana pulp oil obtained by SFE, as well as extracts by PLE and SWE, were evaluated. Extraction with supercritical fluid (40ºC/1.0 kg CO2 h−1/20 MPa/180 min) was the best condition for extracting oil from buritirana pulp (23.09 g 100 g−1), with 75% of efficiency when compared to Soxhlet. Oleic (54 – 55.39%) and palmitic (35.45 – 35.67%) were the main fatty acids in the oil. PLE and SWE extracts were rich in phenolic compounds and showed high antioxidant potential. The main phenolics in buritirana pulp were protocatechuic (32.31 – 361.15 µg g−1), vanillic (13.60 – 320.77 µg g−1), and ferulic (11.86 – 232.24 µg g−1) acids; catechin (0.76 – 386.92 µg g−1); and rutin (51.73 − 6.19 µg g−1). Resveratrol (5.48 – 1.37 µg g−1) in buritirana pulp was reported for the first time in the literature. Sequential extraction was efficient for recovering extracts with high concentrations of bioactive compounds, especially the extracts obtained by SWE at 130ºC. Sequential processes are a high-yield alternative to recover the oil and phenolic fractions from buritirana pulp.
