ABSTRACT
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.
