摘要
为研究超临界CO2萃取胡柚皮总黄酮的工艺,在夹带剂试验和单因素试验的基础上,采用四因素三水平正交试验设计,以萃取压力、萃取温度、动态萃取时间、CO2流量为考察因素,优选了超临界CO2萃取胡柚皮总黄酮的最佳工艺。结果表明:该试验无需使用夹带剂,各因素对得率的影响大小依次为:CO2流量、萃取时间、萃取压力、萃取温度。最佳萃取工艺条件为:萃取压力35 MPa,萃取温度45℃,静态萃取40 min后动态萃取60 min,CO2流量3 L/min,此条件下胡柚皮总黄酮的得率可达1.01 mg/g。
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 35 MPa, extraction temperature was 45℃ , extraction time for dynamic extraction was 60 min after static extraction for 40 min, and the flow rate of CO2 was 3 L/min. Under above process conditions, the extraction yield of Changshanhuyou peel total flavonoids reached to the maximum of 1.01 mg/g.
