| Abstract: | Objective To optimize the extraction technology of the rehmanniae radix. Methods Central composite experimental design and response surface methodology were applied to optimize the best extraction conditions. Extracting time, water to raw material rati- o,number of extraction were the main factors to influence the yield of catalpol and polysaecharide. Results The optimum extraction con- ditions were determined as follows：extraction time 120min,number 4 and water to raw material ratio at 14. Conclusion The method is simple, reasonable, stable, and suitable for industrialized production. |
