摘要
由于藜芦生物碱在藜芦根茎里容易以盐的形式存在,通过碱化使生物碱游离出来,实验证明浓氨水的碱化效果最佳。本文分别用溶剂法,超声萃取法和超临界CO2萃取法萃取藜芦生物碱,实验证明超声萃取法效果最好,萃取条件为:样品用浓氨水碱化1 h,超声波频率为45 kHz,萃取时间为1 h。
As the vertrine easy to mot in veratryl in form of salt, the vertrine freeout by alkalization. Experimental proof： alkalization of concentration of ammonia is the best. In this paper, vertrine was extracted by solvent, ultrasonic extraction and supercritical CO2 extraction respectively.Experimental proof： ultrasonic extraction is the best. Conditions of the extraction： sample was alkalizated by concentration of ammonia for lh, Frequency of ultrasonic extraction is 45 kHz, time of extraction is 1h.
