| 海南岛油茶籽油品质独特，为促进海南岛油茶资源开发利用并为油茶籽油品质性状育种提供参考依据，选取海南岛不同油茶主产区的油茶籽，对油茶种仁含油率及油茶籽油理化指标、无机元素含量、脂肪酸组成和生物活性物质含量进行测定，并对考察指标进行相关分析、品质综合评价和聚类分析。结果表明：海南岛油茶籽种仁平均含油率为49.13%；油茶籽油无机元素含量丰富，不饱和脂肪酸含量在90%左右，角鲨烯含量为78.33~96.23 mg/kg,茶多酚含量为64.78~77.36 mg/kg,维生素E含量为430.7~484.4 mg/kg;某些考察指标之间存在显著或极显著的相关性；定安和海口产油茶籽油综合得分较高，琼海油茶籽油综合得分最低；通过聚类分析，海南岛油茶籽油主产区可分为3类，其中定安为一类，屯昌、琼海、澄迈、临高为一类，海南中部山区、海口为一类。综上，海南岛油茶籽油品质较高，各油茶主产区油茶籽油有其自身特点。 |

| The quality of oil-tea camellia seed oil originated from Hainan Island is unique. To promote the development and utilization of oil-tea camellia resources and further provide a reference for the quality traits breeding of oil-tea camellia seed oil in Hainan Island, oil-tea camellia seed samples from the main oil-tea camellia producing areas in Hainan Island were collected. The oil content in oil-tea camellia seed kernel, the physicochemical indexes, contents of inorganic elements, fatty acid composition and bioactive substances contents in oil-tea camellia seed oil were determined. Subsequently, data on these traits were submitted to do correlation analysis, comprehensive quality evaluation and cluster analysis. The results showed that the average oil content in oil-tea camellia seed kernel was 49.13%. The oil-tea camellia seed oil was rich in inorganic elements, and the contents of unsaturated fatty acid, squalene, tea polyphenol and vitamin E were about 90%, and 78.33-96.23, 64.78-77.36, 430.7-484.4 mg/kg, respectively. Significant or extreme significant correlations were found between some traits. The comprehensive scores of oil-tea camellia seed oil originated from Ding′an and Haikou were relatively higher, while that from Qionghai was the lowest. According to cluster analysis, the main producing areas of oil-tea camellia seed oil in Hainan Island could be divided into three categories, Ding′an into one category, Tunchang, Qionghai, Chengmai and Lingao into one category, and the central mountains and Haikou into one category. In conclusion, the quality of oil-tea camellia seed oil originated from Hainan Island is high, and the oil-tea camellia oil in each main producing area has its own characteristics. |
