Abstract

OBJECTIVE To study the extraction technology for the Rehmannia glutionsa bibosch the optimum extraction process was selected with orthogonal design. The extracting rate was referred as index for checking, the catalpol was referened only.The best extraction process was set up.METHODS The L 9(3 4) orthogonal method. RESULTS The extracting times is the best effect of the extraction technology for the Rehmannia glutionsa bibosch the optimum extraction process. CONCLUSIONS Adding 4 time amount of 60% alcohol into the Chinese medical mreterials and extraction 3 times, 6 days for each time is the best extraction process.
