中文摘要: 罗汉果中黄酮类化合物含量高。选取提取温度、提取时间、料液比3个因素,在单因素试验的基础上,采用响应曲面法研究了超声波提取罗汉果渣中的黄酮的最佳工艺条件,结果表明,当超声温度50.65℃,料液比为1∶34.75(g/mL),超声时间为29.2 min,此时黄酮得率最高,为2.25%。采用超声波辅助法能够有效的提取罗汉果渣中黄酮,方法简单,时间短,效率高。

Abstract:Siraitia grosvenorii is rich in flavonoids.On the basis of single factor test,the response surface method was designed to study the effects of extraction temperature,extraction time,and material liquid rate on flavonoid extraction rate from mare of Siraitia grosvenorii so as to optimize experimental conditions.The results showed that the optimum condition for ultrasonic-assisted extraction of flavonoids was as follows:extraction temperature of 50.65℃,material liquid rate of 1∶34.75(g/mL),and ultrasonic processing time of 29.2 min. Under this condition,the extraction rate of flavonoids was 2.25%.Ultrasonic-assisted method which was simple and efficiency could effectively extract flavonoids from mare of Siraitia grosvenorii.
