忍冬不同器官多糖提取工艺优化及抗氧化活性研究
Optimization of Lonicera japonica polysaccharide extraction process and antioxidant activity of polysaccharide extracts from different organs
摘要
Abstract
[Objective]To develop the medicinal and food resources of Lonicera japonica,improve the yield of polysaccharides,determine the antioxidant activity of different organs,and reduce the waste of natural Chinese medicine resources.[Methods]Different organs of L.japonica are utilized as raw materials,with polysaccharide yield as the primary investigation index.The response surface method is used to determine the optimal extraction process.The in vitro antioxidant activity of different organs is assessed and analyzed by metrological methods.[Results]The optimal extraction conditions are as follows:solid-liquid ratio of 1∶25(g/mL),ultrasonic temperature of 80℃,ultrasonic time of 60 min,ultrasonic power of 190 W.Under these conditions,the polysaccharide yield is as high as 7.01%.The antioxidant activity results demonstrate that different organs of L.japonica exhibit antioxidant effect,with the strength ranking as:leaves≈flowers>vines>fruits.Cluster analysis shows that L.japonica leaves and flowers are classified into one category,making them preferred resources for extracting L.japonica polysaccharides.[Conclusion]The ultrasound-assisted method for extracting L.japonica polysaccharides achieves high yield,and the extracts from different organs maintain high antioxidant capacity.关键词
