摘要： 用化学分析法测定红花油茶果的果皮、茶籽壳、茶籽仁中的主要成分,用毛细管气相色谱法分析红花油茶籽油的脂肪酸组成,并对茶籽仁的子叶细胞形态进行观察 。结果表明 :红花油茶籽仁(干基)中粗脂肪含量为60.3 %,粗蛋白质含量为8.8 %,茶皂素含量为10.3 4% ;红花油茶籽壳(干基)中粗蛋白质含量为2.5 %,粗纤维为73.4 %,茶皂素含量为4.0 8% ;红花油茶果的果皮(干基)中粗蛋白质含量为4.0 %,粗纤维为31.1 %,茶皂素含量为20.0 5% ;红花油茶果子叶细胞平均大小为64.2μm×60.8μm,细胞壁平均厚度为3.0 3μm,细胞壁厚度与细胞大小的比值为7.7 6×10-4,细胞内脂体为椭圆形,大小为1.0～1.3μm 。以上数据表明,红花油茶果可用作食品、化工和化妆品工业原料。对油脂的脂肪酸组成测定表明,红花油茶籽油属油酸型油,油中不饱和脂肪酸含量高达84.8 3%,其脂肪酸组成符合现代保健油脂的标准。
Abstract: The proximate composition of Camellia chekiangoleosa Hu fruit was determined by chemical analysis,and its oil fatty acids were measured by capillary gas chromatography . The morphological structure of C . chekiangoleosa cotyledon cells was observed under the microscope . The results showed that C . chekiangoleosa kernel contained 60.3 % crude fat,8.8 % crude protein and 10.3 4% camellia saponin on dry basis . C .chekiangoleosa testa held2.5 % crude protein,73.4 % crude fiber,and4.0 8% camellia saponin on dry basis . C .chekiangoleosa pericarp had4.0 % crude protein,31.3 % crude fiber,and20.0 5% camellia saponin on dry basis . The average size of C . chekiangoleosa cotyledon cells was 64.2μm×60.8μm . The average thickness of their cell wall was 3.0 3μm and the ratio of cell wall thickness to cell size was 7.7 6×10-4 . The lipid bodies observed in C.chekiangoleosa cotyledon cells were elliptic with a particle size of1.0 to1.3μm . The data suggested that C .chekiangoleosa fruit could contribute to the industries of food,chemistry,cosmetic,etc. In addition,the analysis of capillary gas chromatography showed that C . chekiangoleosa seed oil belonged to oleic acid-type oil with 84.8 3% unsaturated fatty acids,indicating its fatty acid composition was coincided with the modern standards for a healthy vegetable oil .
