The extraction process of maslinic acid (MA) and oleanolic acid (OA) from Olea europare L. pomace as raw material has been studied. The optimum conditions of extracting MA and OA was optimized with orthogonal experiment method by taking extraction rate of MA and OA, total extracts yield as index. The optimum extractions conditions were 10 volumes of φ=90% ethanol reflux extraction 3 h. In the above conditions, extraction rate of MA and OA were 91.27%, 94.73% respectively, and total extracts yield was 23.38%.
