目的:优化野菊花多糖的提取工艺。方法:采用单因素试验和L9(34)正交试验法考察了提取时间、提取温度和料液比对野菊花多糖得率的影响。结果:影响野菊花多糖得率的主次因素为提取温度、提取时间及料液比。最佳提取工艺条件为提取温度90℃,料液比1∶20,提取时间为4 h。结论:在此最佳工艺条件下野菊花多糖得率为3.32%。
Objective: To optimize the extraction process of wild chrysanthemum polysaccharide. Methods: The effects of extraction time, extraction temperature and solid-liquid ratio on the yield of Chrysanthemum morifolium polysaccharides were investigated by single factor test and L9 (34) orthogonal test. Results: The primary and secondary factors influencing the yield of Chrysanthemum morifolium were extraction temperature, extraction time and solid-liquid ratio. The optimum extraction conditions for the extraction temperature of 90 ℃, solid-liquid ratio 1:20, extraction time of 4 h. Conclusion: Under the optimal conditions, the yield of wild chrysanthemum polysaccharide is 3.32%.
