本文研究用脉冲极谱法测定中药谣羊藿中总黄酮的含量,并研究了不同电解质底液中滔羊藿甙的极谱行为,在0.05mol/L硫酸铵底液中,于-1.51V(vs Ag/AgCl)处出现一良好峰形,在1.28 3.85×10~(-6) mol/L范围,浓度与峰电流呈线性关系。生药用70%乙醇提取后,取一定量提取液直接加入底液中进行测定,方法快速简便。 In this paper, pulse polarography was used to determine the total flavonoids content in Chinese traditional medicine, and the polarographic behavior of yangneng in different electrolyte base fluids was studied. In 0.05 mol/L ammonium sulfate base solution, the value was -1.51V. There is a good peak at (vs Ag/AgCl), in the range of 1.28 3.85×10 -6 mol/L, the concentration is linear with the peak current. After crude drug is extracted with 70% ethanol, a certain amount of extract is directly added to the bottom solution for measurement. The method is quick and easy.
