| Abstract: | In connection with the low-level valid extract from ginkgo-tree's leaves in the current marketplace,this paper provides a systemic extract-separated method,which adopts fully extracting in similar dissolving principle to gain high level extract. The critical point in the experiment lies in the selection of extraction agent and manipulating process. |
