In this study, the effect of the extraction method (mechanical pressing, MP and organic solvent, OS) and the specie (Cucurbita argyrosperma Huber, CA; and Cucurbita moschata Duchesne, CM) on the content of bioactive compounds and antioxidant activity of oil from pumpkin of Yucatan, Mexico was investigated. Between the two extraction methods, the oil extracted by MP obtained the highest values for total phenolic compounds (TPC), total carotenoids, squalene, quercetin, β-carotene, fucosterol, stigmasterol and antioxidant activity (DPPH, ABTS and reducing power). Between the two species, the CM oil extracted with MP or OS exhibited the highest values for carotenoids, sterols and antioxidant activity (DPPH and ABTS). Thus, it can be concluded that the method and specie affect the composition of bioactive compounds and antioxidant activity of the pumpkin oil. This information is useful for the extraction of pumpkin oil with a higher content of compounds, of interest for the industry.
在这项研究中，研究了提取方法（机械压榨，MP 和有机溶剂，OS）和物种（墨西哥尤卡坦半岛的南瓜 C. argyrosperma Huber 和 C. moschata Duchesne）对南瓜籽油中生物活性化合物含量和抗氧化活性的影响。在这两种提取方法中，MP 提取的油获得了总酚化合物（TPC）、总类胡萝卜素、角鲨烯、槲皮素、β-胡萝卜素、岩藻甾醇、豆甾醇和抗氧化活性（DPPH、ABTS 和还原能力）的最高值。在这两个物种中，MP 或 OS 提取的 CM 油表现出最高的类胡萝卜素、甾醇和抗氧化活性（DPPH 和 ABTS）。因此，可以得出结论，方法和物种会影响南瓜籽油中生物活性化合物和抗氧化活性的组成。这些信息对于提取具有更高含量的工业感兴趣的化合物的南瓜籽油很有用。
