Abstract
On the basis of single factor experiment, orthogonal test method for 2-α hydroxy for optimizing the extraction technology of ursolic acid, choose L9 (34) orthogonal experiment was carried out to 2-α hydroxy yield of ursolic acid as index, at room temperature (25 øC) under ultra-high pressure, holding time, b Alcohol volume fraction and solid liquid ratio (g: mL) on 2α- hydroxyursolic acid yield. Get the best process conditions for ultra-high pressure 300 MPa, the holding time for 5 min, volume fraction of 90% ethanol, and solid-liquid ratio 1:15, extracting 3 times.2- α hydroxyursolic acid to obtain rate can be Up to 0.415%
