Fatty acids of Euterpe oleracea Mart seeds were analyzed in hexane and diethyl ether extracts. The hexane extract contained dodecanoic acid (3), tetradecanoic acid (4), hexadecanoic acid (7), and 9-octadecenoic acid (10). The diethyl ether extract contained (10). The oil of Mart seeds was obtained firstly by methanol extract and further extracted with diethyl ether. The hexane and diethyl ether extracts were then analyzed for antioxidant effects. Both extracts demonstrated a 1,1-diphenyl-2-picrylhydrazyl radical elimination effect similar to that of α-tocopherol and an active oxygen inhibition effect. Significant quantities (0.6212 mg/mL) of polyphenol, in comparison to the standard rejected gallic acid, were found in the extract oil of Mart seeds by the methanol extraction.
对巴西莓（Euterpe oleracea Mart）种子中的脂肪酸进行了己烷和乙醚提取物分析。己烷提取物含有十二烷酸（3）、十四烷酸（4）、十六烷酸（7）和9-十八碳烯酸（10）。乙醚提取物含有（10）。首先通过甲醇提取物获得巴西莓种子油，然后用乙醚进一步萃取。接着对己烷和乙醚提取物的抗氧化作用进行了分析。两种提取物均表现出与α-生育酚类似的1,1-二苯基-2-苦基肼自由基清除作用以及活性氧抑制作用。通过甲醇萃取发现，巴西莓种子提取油中含有大量（0.6212 mg/mL）的多酚，与标准品棓酸相比。
