多频超声波辅助提取山茱萸多糖工艺研究

Research on extraction of polysaccharides from Macrocarpium offcinalis by multi-frequency ultrasonic

采用多频超声波技术对山茱萸(Macrocarpium offcinalis)多糖的提取工艺进行研究。结果表明,超声波辅助提取能有效提高山茱萸多糖的提取率,影响因素主次关系依次是超声频率>浸提温度>浸提时间>料液比。双频组合超声波优于单频超声波,最优工艺为超声频率双频28/45 kHz,浸提温度52℃,浸提时间80 min,料液比1∶6,山茱萸多糖提取率可达18.92%。

The extraction technology of polysaccharides from Macrocarpium officinalis was studied by multi-frequency ultrasonic.The results showed that ultrasonic-assisted extraction could effectively improve the extraction rate of Macrocarpium offcinalis polysaccha⁃rides,and the order of influencing factors was ultrasonic frequency>extraction temperature>extraction time>solid-liquid ratio.Du⁃al-frequency combined ultrasound was superior to single-frequency ultrasound.The optimum extraction condition was ultrasonic fre⁃quency of 28/45 kHz,extraction temperature of 52℃,extraction time of 80 min,and solid-liquid ratio of 1∶6.The extraction rate of Macrocarpium offcinalis polysaccharide was 18.92%.
