Recently, studies on the by-products from the food industry, such as passion fruit seeds, have significantly increased, as these can have an added value, due to their properties, such as potential antioxidant activity. This study was conducted to determine the presence of piceatannol and resveratrol in various extracts of passion fruit () seeds from Madeira Island and a commercial passion fruit oil was used as reference. The commercial oil and the extracts that were obtained by traditional Soxhlet method with ethanol and acetone did not reveal the presence of the two stilbenes, piceatannol and resveratrol. However, the extracts that were obtained by the ultrasound method showed significant amounts of piceatannol and resveratrol when compared with the commercial oil. The presence of these compounds indicates that this oil could have potential application in cosmetic and pharmaceutical industries, due to their proven antioxidant and anti-aging properties.
最近，对食品工业副产品（如西番莲种子）的研究显著增加，因为这些副产品因其潜在的抗氧化活性等特性而具有附加值。本研究旨在测定来自马德拉岛的西番莲（）种子的各种提取物中白皮杉醇和白藜芦醇的存在情况，并以一种市售西番莲籽油作为参考。通过传统索氏提取法用乙醇和丙酮获得的市售油和提取物未显示出这两种芪类化合物（白皮杉醇和白藜芦醇）的存在。然而，与市售油相比，通过超声法获得的提取物显示出大量的白皮杉醇和白藜芦醇。这些化合物的存在表明，由于其已被证实的抗氧化和抗衰老特性，这种油在化妆品和制药行业可能具有潜在应用。
