【摘要】 绿原酸具有抗氧化、清除体内自由基、抑制突变与抗肿瘤等多种生理活性。对超临界CO₂萃取葵粕绿原酸的影响因素（夹带剂种类、浓度、用量、萃取温度、压力、时间以及CO₂流量）进行了详细的分析和讨论。结果表明,以上因素对绿原酸萃取率都有一定的影响,在各单因素试验条件下选择乙醇作为夹带剂、乙醇浓度70%、乙醇用量400 mL/100 g、萃取温度50℃、萃取压力30 MPa、萃取时间5 h和CO₂流量3.5 L/h为好。更多还原

【Abstract】 Chlorogenic acid has many physiological activities such as antioxidation,removing vivo free radicle, suppressor mutation and antitumor.Influencing factors of supercritical CO₂ extraction of chlorogenic acid from sunflower seeds,including modifier category,concentration,dosage,extraction pressure,temperature,extraction time and CO₂ flow rate,were analyzed and discussed in full.Results showed that all factors had some effects on extraction yield of chlorogenic acid.On the basis of results of single-factor experiments,modifier category, concentration,dosage,extraction pressure,temperature,extraction time and CO₂ flow rate was alcohol,70% alcohol,alcohol dosage 400 mL/100 g,extraction tempresure 50℃,extraction pressure 30 MPa,extraction time 5 h and CO₂ flow rate 3.5 L/h,respectively.更多还原
