| 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 |
