AIM: To Structure a series of diversifying combination of ginsenoside in order to provide the different samples for the pharmacological and pharmacodynamics experiments. METHODS: UNIFAC group contribution method is used for simulating the liquid liquid extraction, the proper extractants are chosen to carry out the experiments, and then the contents of the ginsenosides obtained with different extractants are detected through HPLC. RESULTS: The contents of the main ginsenoside varied with the change of the e...
