Abstract:
Objective:To Study on the best extraction method of huperzine A.Methods:Using the single factor inspection and the orthogonal design of experiment,take contents of huperzine A as the target,inspect the condition of extraction process.Results:The best extraction condition is using 10 times of pH=1 sulfur acid pickling and lixivia- ting 12h,then extracting 30 min for 2 times with ultrasonic extraction,adjusting solution for pH=9 with NaOH alka- lize.Conclusion:The extraction method is scientific and practical...
