八种山茶属植物种子油脂的脂肪酸分析 . Fatty acids analysis of seeds oil from eight kinds of Camellia plants

Abstract

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.
