  • Camellia chekiangoleosa Hu,Camellia reticulata and Camellia semiserrata,which are cultivated on a large scale in China,were selected as materials in order to study qualities of main Camellia chekiangoleosa seed oils systematically.Oil content of seeds was determined.Physicochemical indexes,nutritional ingredients and fatty acid profiles ofoils were analyzed. Gray correlation method and principal component analysis were used to make a comprehensive evaluation.Results showed that oil content of Camellia chekiangoleosa Hu was up to 68.53%,being the highest of these three kinds. The comprehensive evaluation scores of physicochemical indexes and main nutritional ingredients of it were 0.892 and 1.000,respectively,also proved to be the highest. There were minor differences between fatty acid profiles of Camellia chekiangoleosa seed oils,and oleic acid was the main ingredient with the contents of 79.1%,72.3%,75.7% in Camellia chekiangoleosa Hu,Camellia reticulata and Camellia semiserrata seed oils respectively. Total unsaturated fatty acid contents were found relatively higher in Camellia chekiangoleosa Hu and Camellia semiserrata seed oils,being 86.7% and 86.9%.Comprehensively,quality of Camellia chekiangoleosa Hu seed oil was better.
