Method of extracting oleanolic acid and ursolic acid from pawpaw

The invention relates to a method of extracting oleanolic acid and ursolic acid from a pawpaw. The method of extracting the oleanolic acid and the ursolic acid from the pawpaw includes that a fresh pawpaw is dried in the sun, grinded, and boiled in water to get extracting solution, concentration of the extracting solution is adjusted, the extracting solution is filtered to get supernate, and the supernate is separated by macroporous resin. Through the method of extracting the oleanolic acid and the ursolic acid from the pawpaw, extractive which is high in content of effective elements can be achieved, the method of extracting the oleanolic acid and the ursolic acid from the pawpaw is without large scale equipment, short in extraction time, high in production efficiency, simple in processing steps, moderate in conditions, safe and non-toxic in reagent, and environmental friendly. The method of extracting the oleanolic acid and the ursolic acid from the pawpaw is provided with wide industrial application value
