Objective:
To explore the best ultrafine vibration extraction technology of Rhizoma Chuanxiong.
Method:
Using the content of ligustrazine hydrochloride and ferulic acid as determination indexes, quadrature test was used to choose extraction times, time, solvent amount and to compare with the result of conventional extraction technology.
Result:
The best condition of the Rhizoma chuanxiong was with 90% ethanol of 4 times volume, extracting 2 times in 25 degrees C, 15 minutes each time. Comparing with conventional extraction technology, extraction time of UVET was 1/6, solvent amount was 4/7, the extraction rate of marker components was 1.19 and 1.09 times, respectivley.
Conclusion:
UVET can improve the extracting rate of effective constituents, reduce the time and solvent amount and be used in industrialization.
