This paper deals with the quantitative determination of the total alkaloids in Radix Gelsemii and its preparation by colorimetric method with acid dye. It is shown that the mean contents of total alkaloids in Radix Gelsemii and its alkaloids injection were 0.621% and 5.02 mg/ml respectively, and the mean recovery was 96.87%.
