- 摘要:
- 以灵芝真菌为试材，在单因素试验基础上，采用L9（34）正交实验研究了CO2超临界萃取灵芝真菌菌丝体中灵芝酸的最佳工艺条件。结果表明：萃取压力对灵芝酸提取量影响显著，而萃取温度、CO2流量影响不显著，3个因素的适宜组合为萃取压力30 MPa、萃取温度30℃、CO2流量1.6 L/min，经试验验证，该条件下，灵芝酸萃取量为(23.93±1.85) mg/g，表明此条件较为适宜于灵芝中灵芝酸的提取。
- Abstract:
- Taking Ganoderma lucidum as material,the optimization of Ganoderic acids from Ganoderma lucidum after fermentation were studied by supercritical fluid extraction methed.On the basis of single factor experiment，L9(34)orthogonal was used to optimize the extraction conditions.The results showed that the extraction pressure was significant factors，while extraction temperature and CO2 velocity had no significant effect on the yield of ganoderic acids.The optimization conditions was as follows：30 MPa extraction pressure，extraction temperature 30℃，CO2 flow 1.6 L/min，the content of Ganoderic acids reached (23.93±1.85) mg/g under the conditions,so the optimization conditions was suitable for the Supercritical fluid extraction of Ganoderic acids from Ganoderma Lucidum after fermentation.
