油橄榄果渣中山楂酸和齐墩果酸的提取工艺

Extraction Technology of Maslinic Acid and Oleanolic Acid from Olea europare L. Pomace

摘要:

以油橄榄果渣为原料，对其主要有效成分山楂酸和齐墩果酸的提取工艺进行研究。以MA、OA的提取率和浸膏得率为评价指标，采用正交实验优选油橄榄果渣中MA、OA的最佳提取工艺。最佳条件为：以10倍量φ=90%的乙醇回流提取3 h，提取1次。MA、OA提取率分别为91.27%、94.73%，浸膏得率为23.38%。

Abstract:

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%.
