Optimization of extracting enzymolysis technology for the Geranium

OBJECTIVE To optimize the extracting enzymolysis technology for the Geranium.METHODS The content of tannin was as the index,orthogonal design method was used for optimization.RESULTS The optimum extracting enzymolysis technology for the Geranium was as follows:the cellulase amount was 10 U/g,the enzymolysis temperature was 60 ℃,and enzymolysis time was 60 minutes.CONCLUSION The optimized extracting enzymolysis technology for the Geranium is simple,steady and high extracting rate.
