摘要
对南方红豆杉种子 (种仁 )的化学成分分析表明 :南方红豆杉干重 (DW)种子粗蛋白、粗脂肪、淀粉、可溶性糖的质量分数wDW分别为 9.92g (10 0g) -1,72 .86g (10 0g) -1,4 .15g (10 0g) -1,0 .38g (10 0g) -1;氨基酸的wDW为 9.10g (10 0g) -1,其中必需氨基酸占总氨基酸量的 2 8.0 5 % ;种子油脂肪酸组成以不饱和的油酸和亚油酸为主 ,其相对含量为 4 8.4 %和 4 2 .2 % ;种子元素质量分数分别为 :wDW(N) =15 87.2mg (10 0g) -1,wDW(P) =5 6 5 .4mg (10 0g) -1,wDW(K) =2 6 1.1mg(10 0g) -1,wDW(Ca) =18.4mg (10 0g) -1,wDW(Mg) =35 0 .5mg (10 0g) -1,其余微量元素含量由多到少依次为Zn >Fe>Na>Cu >Mn .表 4参
The chemical composition in the seed of Taxus chinensis var. mairei was reported in this paper. The constituents in 100 g seed (DW) of T. chinensis var. mairei contained protein 9.92 g, fat 72.86 g, starch 4.15 g, soluble carbohydrate 0.38 g and 9.10 g amino acids of the protein. The ratio of essential amino acids to total amino acids was 28.05 %. Oleic acid and linoleic acid accounted for 48.4 % and 42.2 % in seed oil, respectively. The macronutrients in 100 g seed (DW) included N 1 587.2 mg, P 565.4 mg, K 261.1 mg, Ca 18.4 mg and Mg 350.5 mg. The order of the micronutrients contents in the seed was Zn>Fe>Na>Cu >Mn.
