| titleOfInvention | Preparation method for and application of esculetin in microsorum fortunei |
| abstract | A method for preparing esculetin in Microsorum fortunei, mainly comprising: crushing dried stems and leaves of Microsorum fortunei, extracting using an ethanol solution, ethyl acetate, separating by means of silica gel column chromatography, separating by means of MCl column chromatography, separating by means of Sephadex LH-20 column chromatography, separating by means of medium pressure reversed phase silica gel column chromatography, and then concentrating and drying to obtain a target product. Experiments show that in terms of an in vitro anti-hepatitis B virus effect, the esculetin in Microsorum fortunei obtained in the present invention is effective and has low toxicity, and has a better effect than the positive control lamivudine, thus having prospects in preparing anti-HBV drugs. |
