Abstract

OBJECTIVE:To optimize the extraction technology of Radix Arnebiae gel.METHODS:Orthogonal design was carried out to optimize the extraction technology of Radix Arnebiae gel using the concentration and amount of ethanol and extraction time as factors and using the content of shikonin as index.RESULTS:The optimal extracting technology was as follows:16-folds 95% alcohol for 3 hours.The content of L-shikonin was 5.672 mg·g-1.CONCLUSION:The extraction of L-shikonin is stable and feasible for the extraction of Radix Arnebiae from Radix Arnebiae gel.
