| titleOfInvention | Metasequoia glyptostroboides bark extract, preparation method thereof and uses thereof |
| abstract | The invention discloses a Metasequoia glyptostroboides bark extract, a preparation method thereof, and uses thereof. The preparation method comprises the following steps: 1, extracting Metasequoia glyptostroboides bark powder in an extraction solvent at a temperature in a range from 25DEG C to a reflux temperature for 2-24h, and filtering out residues to obtain an extract solution; 2, cooling the extract solution, filtering, and concentrating the resulting filtrate to obtain a first concentrate; and 3, extracting the first concentrate with ethyl acetate, degreasing with petroleum ether or chloroform, and drying to obtain the Metasequoia glyptostroboides bark extract; or carrying out macroporous adsorption resin column chromatography on the first concentrate, collecting the resulting eluate, and concentrating and drying the eluate to obtain the Metasequoia glyptostroboides bark extract. The method has the advantages of simple operation, low cost, and no need of special devices, and is suitable for industrialized production. The Metasequoia glyptostroboides bark extract contains abundant proanthocyanidin and polyphenol components, and has a strong free radical removing effect, a strong antioxidation capability, a tyrosinase inhibition effect, an alpha-glucosidase inhibition effect and a cardiovascular protection effect. |
