| Abstract: | OBJECTIVE:To study the bset extracting conditions of robdosia rubescens hemsl in the cold - soaked way.METHODS:A orthogonal test method was used,the solvent dosage,extracting time and extracting times are the three factors in the experiment. And we choose three levels of each factor to do the experiment. RESULTS: The actor A and B has conspicuous effect on the concent of oridonin, the factor C has only certain effect. CONCLUSION: The best extracting process is A3B3C2,i e.extracting twice by using ten times of EtOH(95%) ,six days once. |
