Method for efficiently extracting ginkgetin |
| abstract |
The invention discloses a method for efficiently extracting ginkgo flavone, which adopts a semi-bionic enzyme method to extract total flavone components in ginkgo leaves, and obtains extractum by crushing, dipping, enzyme extraction and drying. The invention selectively extracts active ingredients by simulating different pH environments of the medicine in a human body; seed powder is used as an enzyme raw material to destroy the cell wall of the ginkgo leaf so as to achieve the purpose of accelerating the extraction of flavone. The method has the advantages of high extraction rate, mild extraction conditions, simple operation, environmental friendliness and suitability for industrial production. |
