    摘要:

    為研究超臨界CO2萃取胡柚皮總黃酮的工藝，在夾帶劑試驗(yàn)和單因素試驗(yàn)的基礎(chǔ)上,，采用四因素三水平正交試驗(yàn)設(shè)計(jì),，以萃取壓力,、萃取溫度、動(dòng)態(tài)萃取時(shí)間、CO2流量為考察因素，優(yōu)選了超臨界CO2萃取胡柚皮總黃酮的最佳工藝,。結(jié)果表明：該試驗(yàn)無(wú)需使用夾帶劑，各因素對(duì)得率的影響大小依次為：CO2流量,、萃取時(shí)間,、萃取壓力、萃取溫度,。最佳萃取工藝條件為：萃取壓力35MPa,，萃取溫度45℃，靜態(tài)萃取40min后動(dòng)態(tài)萃取60min,，CO2流量3L/min,，此條件下胡柚皮總黃酮的得率可達(dá)1.01mg/g。

    Abstract:

    Extraction method of Changshanhuyou peel total flavonoids by supercritical carbon dioxide fluid was studied. On the basis of entrainer test and extraction pressure, extraction temperature, dynamic extraction time, CO2 flow rate, orthogonal experiment was carried out. The results showed that entrainer was unnecessary and the optimum extraction pressure was 35MPa, extraction temperature was 45℃, extraction time for dynamic extraction was 60min after static extraction for 40min, and the flow rate of CO2 was 3L/min. Under above process conditions, the extraction yield of Changshanhuyou peel total flavonoids reached to the maximum of 1.01mg/g.
