八种山茶属植物种子油脂的脂肪酸分析

分析了山茶属中茶、窄叶短柱茶、香花糙果茶、大白山茶、博白油茶、越南油茶、大果红山茶和油茶8种山茶属植物种子的出籽率、出仁率和出油率,并用GC-MS分析了油脂的脂肪酸组成及含量。实验结果表明,茶、窄叶短柱茶、油茶和越南油茶出籽率较高,油茶、窄叶短柱茶、越南油茶、大白山茶和茶的出仁率较高,油茶、窄叶短柱茶、越南油茶和香花糙果茶4种植物种子的出油率均高于40%。8种油脂中油酸含量为44.20%~81.07%,总不饱和脂肪酸含量为69.60%~86.28%。综合分析,与已作为油料资源的油茶相比,7种山茶属植物都可作为新的油料,其中窄叶短柱茶和越南油茶最具开发前景。

Fatty acids analysis of seeds oil from eight kinds of Camellia plants

The seed yield and kernel yield of eight kinds of Camellia plants(C.sinensis,C.fluviatilis,C.suaveolens,C.albogigas,C.gigantocarpa,C.vietnamensis,C.magnocarpa and C.oleifera) were analyzed.The oil yield of plant seeds were determined,and the fatty acid compositions were analyzed by GC-MS.The results indicated that the seed yield of C.sinensis,C.fluviatilis,C.oleifera and C.vietnamensis were high,the kernel yield of C.oleifera,C.fluviatilis,C.vietnamensis,C.albogigas and C.sinensis were high.The oil yield of C.oleifera,C.fluviatilis,C.vietnamensis and C.suaveolens were beyond 40%.The oleic acid contents of these plant oils were 44.20%~81.07%,the unsaturated fatty acid contents were 69.60%~86.28%.Compared with C.oleifera,the other seven plants can be used as new oil plants,among them C.fluviatilis and C.vietnamensis are more hopeful.
