【Abstract】 Object: To look for an extraction of Scutellaria baicalensis from which Baicalin and Baicalein can be extracted in a designed ratio. Methods: Utilizing the biological enzyme coexisted in the raw material of Scutellaria baicalensis, the extract which contains Baicalin and Baicalein in a certain ratio was obtained by a mildly enzymic hydrolysis of the Baicalin to Baicalein. Results: The ratio of the glycoside and its gene in the extract can be aimed by controlling the condition of enzymic hydrolysis.Conclusion: This article provide a useful reference to extract Scutellaria baicalensis flexibly.更多还原
