摘  要:
To optimize the extraction technology for ursolic acid of Folium Ilicis Cornutae by cellulase.The extraction technology for ursolic acid of Folium Ilicis Cornutae was optimized by single factor and orthogonal experiment with the use of the extraction rate of ursolic acid as the assessment index.The optimal enzymolysis conditions were as follows: the pH of extracting media was 5.2,the amounts of cellulose was 6 mg/g,the enzymolysis temperature was 50℃and the enzymolysis time was 3 h.It was shown by an approval test that the optimized technology was stable,feasible and suitable for the extraction of ursolic acid of Folium Ilicis Cornutae.
