摘要
目的:研究微波辅助提取小石花菜多酚的工艺条件及多酚抗氧化活性。方法:实验讨论了微波辐射功率、微波提取时间、甲醇浓度以及液固比对小石花菜多酚提取率的影响,并对小石花菜多酚的抗氧化能力进行测定。结论:提取小石花菜多酚的最佳条件如下:微波辐射功率800w,甲醇浓度15%,液固比(mL/g)25,微波辐射时间30s。结果:微波辅助提取小石花菜多酚具有省时、高效等优点。
Objective：To investigate microwave-assisted extraction of polyphenols from Gelidium divaricatum Marteus and antioxidant activity of polyphenols. Methods： The effect of power of microwave,microwave treatment time,volume ratio of methanol,ratio of solid to liquid on extraction of polyphenols were studied,respectively. Results： The optimum process conditions obtained are as following：microwave power is 800w,15% methanol as extracting solvent,ratio of liquid to solid is 25（g/ml）,microwave extraction time is 30 seconds. Conclusion：Microwave-assisted extraction of polyphenols from Gelidium divaricatum Marteus is an efficient method.
