摘要
采用超临界CO2流体技术对虎杖中白藜芦醇进行萃取,获得了初步萃取条件:萃取釜压力25MPa,温度50℃;解析釜压力5.7MPa,温度46℃,用无水乙醇及CY(自制)作为改性剂,同时用HPLC对萃取物进行白藜芦醇含量测定,可知CY作为改性剂效果最佳.
Reveratrol,a microactive factor for preventing Hunan cancer, is successfully extracted from Polygonum cuspidatum by supercritical fluid (SF) CO2.The extraction pressure used in the experiments is 25 MPa and the temperature is 50 ℃,the pressure of separator is 5.7 MPa the temperature 46 ℃,0.2 mL CY and ethanol as modifier. Resveratrol in extraction is analyzed with HPLC.
