摘要
目的:研究桑叶黄酮和多糖成分的提取工艺,通过正交实验获得最佳提取方案。方法:通过单因素实验筛选对提取有显著影响的因素进行正交实验,获得最佳提取方案。结果:黄酮最佳提取方案:固液比1:30,温度80℃,pH=8。多糖的最佳提取方案:固液比1:40,温度70℃,pH=7。结论:用水提法,对桑叶黄酮和多糖共同进行提取是可行的,并通过大孔树脂可以实现将二者有效地分离。
Object: To optimize the extracting and separating process for flavonoids and polysaccharides from mulberry leaves. Methods: Pass the single factor experiment to get the factors that show the important influence and by orthogonal design to the factors to optimize the extracting and separating process. Results: The optimum extracting and separating conditions were 1:30 the solid to liquid, 80℃ extracting temperature and pH=8 extracting and separating process for flavonoids, and were 1:40 the solid to liquid, 70℃ extracting temperature and pH=7 extracting and separating process for polysaccharides from mulberry leaves. Conclusion: The optimized process is stable and highly efficient with the water to extract and separate with macroeticular resin flavonoids and polysaccharides from mulberry leaves.
