ABSTRACT
Objective:
To ascertain the condition for extracting tetramethylpyrazine from Rhizoma Chuanxiong with alcohol.Methods:
With the transferring rate of tetramethylpyrazine as index, the optimum extraction condition for the first time was selected by uniform test, and the times of extraction was studied.Results:
Taking 80% alcohol as solvent, Rhizoma Chuanxiong was extracted two times with 8 and 6 times volume of alcohol for 2hr and 1.5hr, respectively. In this condition, tetramethylpyrazine could be effectively extracted.Conclusion:
The experimental results provided the basis for the ascertainment of extraction process of Rhizoma Chuanxiong preparation.
