Abstract:
Objective:To establish an Ehrlich reaction-colorimetry method for determining furostanol saponins in saponins extract from Radix Asparagi.Methods: Based on the coloration reaction between furostanol saponins and p-dimethylaminobenzaldehyde,a colorimetry method was established to determine the content of furostanol saponins in saponins extract from Radix Asparagi at 510 nm.Saponins AC-9 was measured as reference in the determination.Results: The standard curve of saponins AC-9 showed good linearity in the range of 0.08-0.40 mg and the average recovery was 99.79%(RSD=(1.05%).) Conclusion: This method is rapid,accurate and easy to be carried out,and it can be used to control the quality of Radix Asparagi.
