| 中文摘要: |
| 采用索氏抽提仪、气-质联用仪、高效液相色谱仪、紫外分光光度计对云南11种油料作物油脂中植物甾醇、角鲨烯、维生素E、类胡萝卜素和总酚含量进行测定分析。结果表明：植物油脂中的植物甾醇均以β-谷甾醇为主，β-谷甾醇含量最高的为菜籽油，总植物甾醇含量最高的也为菜籽油；橄榄油中角鲨烯的含量最高，达0.637%，明显优于其他植物油脂；红花籽油中维生素E含量最高，达19.90 mg/100 g（以α-生育酚计）；花生油中类胡萝卜素含量最高，达18.10 mg/100 g；菜籽油中总酚含量最高，达247.91 mg/kg。通过主成分分析并对11种植物油脂的主要功能性成分综合得分进行排序，得分由高到低为菜籽油>橡胶籽油>花生油>红花籽油>橄榄油>大豆油>青刺果油>油茶籽油>油藤果油>核桃油>澳洲坚果油。因此，如果仅从脂溶性成分来看，菜籽油最优，橡胶籽油次之 |
| 英文摘要: |
| Phytosterols, squalene, vitamin E, carotenoids and total phenols contents in oils from eleven oil crops in Yunnan were determined by Soxhlet extractor, GC-MS, HPLC and UV spectrophotometer. The results showed that β - sitosterol was the main phytosterol in vegetable oil, and the contents of β - sitosterol and total phytosterol in rapeseed oil were the highest. The content of squalene in olive oil was the highest, up to 0637%, which was significantly superior to other vegetable oils. Safflower seed oil had the highest content of vitamin E, reaching 19.90 mg/100 g(α-tocopherol). Peanut oil had the highest content of carotenoids, up to 18.10 mg/100 g. The content of total phenols in rapeseed oil was the highest (247.91 mg/kg). The comprehensive scores of the main functional components of eleven kinds of vegetable oils were ranked by principal component analysis, and the highest score was rapeseed oil, followed by rubber seed oil, peanut oil, safflower seed oil,olive oil,soybean oil, prinsepia utilis royle oil, oil-tea camellia seed oil, Sacha Inchi oil, walnut oil and macadamia oil. Therefore, if only considering the fat soluble components, rapeseed oil was the best, followed by rubber seed oil. |
