摘要
目的:考察广藿香的超声辅助提取工艺。方法:以提取时间,乙醇浓度和液料比为影响因素,以广藿香醇的含量为指标,利用单因素法考察广藿香超声辅助提取工艺,并采用GC-FID法测定提取物中广藿香醇的含量。结果:确定的最佳提取条件为:超声时间30 min,乙醇浓度为95%,液料比20∶1 mL·g-1。在该工艺条件下,广藿香醇的提取率为32.75%,含量为0.15%。结论:该提取方法工艺简单、提取率高,适合工业化生产。
Objective: To investigate the ultrasound-assisted extraction process of Pogostemon cablin. Methods: Taking the extraction time(min), ethanol concentration(%), and liquid-solid ratio(mL · g-1) as influence factors, patchouli alcohol(PA)content as index, single-factor test was applied to the investigation of extraction-process of Pogostemon cablin. By ultrasonic-assisted extraction, the GC-FID was used to determine the PA content in extract. Results: The optimal extraction conditions were as follows: the ultrasonic time was 30 min, the ethanol concentration was 95%, and liquid-solid ratio was 20∶1 mL·g-1. Under this condition, the extraction rate and the content of PA were 32.75%, and0.15% respectively. Conclusion: This extraction method is simple, but has higher extraction rate. It is suitable for the industrial production.
