[Studies on the extraction process of Cryptoporus volvatus oil by orthogonal design method].
OBJECTIVE
To choose the best extraction process of Cryptoporus volvatus oil by orthogonal design method.


METHODS
The process was studied by orthogonal design method with the extraction ratio of the oil as criteria, and three factors were chosen, including the soak time, the decoct time and the water amount.


RESULTS
The best extraction process was as follow: The crude drug was soaked for 1 h and decocted for 8 h and 10 times water was added.


CONCLUSIONS
The extraction process is simple and easy to produce.
