Objective: To optimize the extraction techniques of Geli Weiyanxiao. Method: The selection of optimum proess was investigated by L9(34) orthogonal design with the Geli Weiyanxiao as the observation index. Result: Water extraction process: to smash the best size for coarse particles
plus 10 times the volume of water
from 1 hour
3 times. Ethanol extraction process: to smash the best size for 10 mesh number
adding10-fold 70% ethanol
eatracting for 2 times
2 hours for each extraction; In consideration of cost-saving and the results of various indexes
the optimal process condition was selected as follows: the best size for coarse particles
plus 10 times the volume of water
from 1 hour
3 times. Conclusion: The optimal extraction technique for Geli Weiyanxiao is stable and reliable.
