对含有有益不饱和脂肪酸和植物化学物质的潜在未充分利用的油类资源——中国胡子籽油的特性研究文献有限。本研究对3个栽培品种大黄果实和种子的化学成分、制备的大黄果实和种子油的理化性质、化学成分和抗氧化能力进行了研究和比较。结果表明，不同品种的菝葜果实、种子及其精油的化学成分含量存在不同程度的差异。果仁蛋白质含量较高（14.38±1.24 ~ 14.88±0.85%），油脂含量较高（19.68±0.68 ~ 20.27±1.33%）。果油和籽油中亚油酸（分别为51.41±1.18-53.76±3.01%和74.82±3.14-75.58±2.32%）和油酸（分别为15.00±1.04-15.59±2.06%和12.68±1.15-13.44±1.08%）等不饱和脂肪酸含量较高。大黄籽油含有大量的生育酚/生育三烯醇、植物甾醇和多酚，因此抗氧化能力明显高于果油。本研究的结果表明，胡麻籽和油可作为膳食食品和营养补充剂行业的优质原料和原料。
There is limited literature available regarding the characteristics ofRhus chinensisMill fruit and seed oils, which are potential underutilized oil resources with beneficial unsaturated fatty acids and phytochemicals. In this study, chemical compositions of three cultivars ofRhus chinensisMill fruits and seeds, as well as profiles of physicochemical properties, chemical compositions, and antioxidant capacities of the preparedRhus chinensisMill fruit and seed oils were investigated and compared. Results suggested that the contents of chemical components of theRhus chinensisMill fruit and seed and their corresponding oils varied to different extents with the certain cultivars.Rhus chinensisMill seeds exhibited relatively high protein contents (14.38 ± 1.24–14.88 ± 0.85%), whereas the oil contents of the fruits were relatively high (19.68 ± 0.68–20.27 ± 1.33%).Rhus chinensisMill oils were abundant in unsaturated fatty acids such as linoleic acid (51.41 ± 1.18–53.76 ± 3.01% and 74.82 ± 3.14–75.58 ± 2.32% for the fruit and seed oils, respectively) and oleic acid (15.00 ±1.04–15.59 ± 2.06% and 12.68 ± 1.15–13.44 ± 1.08% for the fruit and seed oils, respectively).Rhus chinensisMill seed oils contained high contents of tocopherol/tocotrienol, phytosterol, and polyphenol, thus resulting in significantly higher antioxidant capacities than the fruit oils. The results observed in the present work illuminated that theRhus chinensisMill fruit/seed and oil can be regarded as high-quality sources and ingredients for dietary food and nutritious supplement industries.
