自制粗茶多糖呈灰白色粉末状,用葡萄糖做标准曲线,蒽酮-硫酸法测定其含量为15%。
The crude TPS, extracted from green tea in this laboratory, was a kind of powdery and gray material, and contained polysaccharides about 15% by anthrone-vitriol method employed glucose as standard.
结果用此方法测定多糖的标准曲线,其相关系数为0。9997,平均回收率为99。62%,相对标准偏差为1。
Results The correlation coefficient of standard curve was 0.999 7, the recovery rate was 99.62 % and RSD was 1.94 %.
