Pumpkin seed oil (PSO), a rich source of nutrients, is extracted from the seeds of different pumpkin varieties for food and medicines. This article aims to provide an evidence-based review of the literature and to explore the extraction technologies, nutritional properties, and biological activity of PSO. From previous literature, PSO contains a large proportion of unsaturated fatty acids, with linoleic acid as the main component, and an amount of tocopherol, phytosterol, and phenolic acids. Some differences in the yield, composition, and physicochemical properties of PSO can be associated with the pumpkin's cultivars and the extraction methods. Some novel technologies involved in supercritical fluid extraction, enzyme-assisted aqueous extraction, and ultrasound-assisted extraction have been replacing the conventional technologies gradually as promising methods for the safe, non-polluting, and effective recovery of PSO. This healthy vegetable oil was reported by several in vitro and in vivo studies to have potential protective roles in oxidative stress, inflammation, cancer, and cardiovascular diseases. © 2023 Society of Chemical Industry.
南瓜籽油（PSO）富含营养成分，是从不同南瓜品种的种子中提取出来用于食品和医药领域的。本文旨在对相关文献进行循证综述，探讨南瓜籽油的提取技术、营养特性和生物活性。从以往文献来看，南瓜籽油含有很大比例的不饱和脂肪酸，其中亚油酸为主要成分，还含有一定量的生育酚、植物甾醇和酚酸。南瓜籽油在产量、成分和理化性质方面的一些差异可能与南瓜品种及提取方法有关。超临界流体萃取、酶辅助水相萃取和超声辅助萃取等一些新技术已逐渐取代传统技术，成为安全、无污染且有效提取南瓜籽油的有前景的方法。多项体外和体内研究表明，这种健康的植物油在氧化应激、炎症、癌症和心血管疾病方面具有潜在的保护作用。© 2023 化学工业协会。
