Title: Research the Extracting Technology of Nuanqigao
Abstract: Objective:To investigate the extracting technology of Nuanqigao.Methods: An orthogonal experiment was designed and carried out.The contents of Imperatorin in the extracts of Nuanqigao under different conditions were detected with HPLC.The contents of Imperatorin and the weights of dry paste in the extracts of Nuanqigao were choosed as indexes to evaluate and judge the optimum extracting technology of NuanQiGao.Results: The optimum extraction condition was as follow: extracting 3 times(1hours /time) by hot reflux with 8 time amount of 75% alcohol.Conclusion: The proper process of extracting Nuanqigao is set up.It is feasible,stable and suitable to industrialized production.
