ObjectTo study the application of ultrasonic circulation technique for the extraction of triterpenoids from Ganoderma lucidum (Leyss.ex Fr.) Karst. Methods On the basis of conventional method, the processing steps of ultrasonic circulation treatment were added. Results The comparative experiments showed that less amounts of various solvents and shorter extraction time were needed for ultrasonic circulation extraction, with the product ratio of about 40 percent higher than that of conventional method. Furthermore, a good consistency of the target product analyzed by HPLC was found between two different extraction methods. Conclusion The ultrasonic circulation technique has a potential application to the extraction of triterpenoids from G. lucidum.
