摘要
采用薄层层析-紫外分光光度法测定了党参中党参甙Ⅰ的含量,回收率99.92%,变异系数1.77%。同时测定了几种不同党参样品含量,发现霜冻后采取的党参其含量比一般党参高近一倍。
A method of thin layer chromatographic separation and ultraviolet spectrophotometric determination of tangshenoside Ⅰ in Codonopsis pilosula is described. A comparison of the contents in various samples is made. The contents of tangshenoside Ⅰ in frosted sample have been found to be twice as much as in normal drug. The recovery of tangshenoside Ⅰ is 99.92% and the coefficient of variation of eight samplings is 1.77%.
