| 摘 要： | 研究了常规热水法、超声波、微波、超声波预处理-热水提取和超声波-微波联用5种方法提取菊花总糖的工艺。结合苯酚-硫酸显色法,以菊花总糖提取量为考察指标,采用SAS软件对5种方法的提取结果进行统计分析。结果表明:超声波-热水法、超声波-微波法与常规热水法相比,结果差异显著(P>0.05),提取率大于常规法;超声波法、微波法与常规热水法相比,提取率差异不显著(P<0.05),其中超声波-热水处理法提取率最高。在菊花质量为5 g,料液比(g/mL)为1∶25,超声波功率500 W,温度60℃的实验条件下,先用超声波预处理30 m in,再在85℃的热水中回流提取30 m in,菊花总糖得率最高达到9.86%,比热水法的提取率高1.94%。这种提取方式提取效率高,安全可靠。

| Abstract: | The five methods of hot water,ultrasonic,microwave,ultrasonic pretreatment-hot water and ultrasonic-microwave combination to extract polysaccharides from Chrysanthemum were studied.The content of polysaccharides in the Ch.was determined with the method of phenol-sulfuric acid,and the software of SAS was used to analyze the data.The results showed that: the extraction rates of Ch.saccharides by the ultrasonic pretreatment-hot water method and the ultrasonic-microwave method were remarkable higher than that b... |
