摘要
采用比色法 ,以三氯化铁 -冰醋酸 -浓硫酸的混合溶液为显色剂 ,测定娑罗子总皂甙含量 ,r=0 .9993,线性范围为 2 4～ 4 70μg。
A colorimetric method was described for estimation of total saponins in Semen Aesculi.The color reagent was a mixture solution of ferrum trichloride,glacial acetic acid and concentrated sulfuric acid.The correlation coefficient was 0.9993.The linear range was between 24 μg and 470 μg.
