| titleOfInvention | Purslane extract and preparation method thereof |
| abstract | The invention belongs to the technical field of traditional Chinese medicines or cosmetics, and particularly relates to a purslane extract and a preparation method thereof. The extract is prepared by the following steps: drying taken purslane; with 95% ethanol as an entrainer, carrying out CO2 supercritical fluid extraction, adding 1,3-butanediol to an extract, completely recovering a reagent from an organic layer, and drying the reagent to obtain an extract A; carrying out enzyme hydrolysis on residues after supercritical extraction, adding water to extract, filtering and adding activated carbon and clay to the extract liquid, centrifuging and drying the extract liquid to obtain an extract B; and mixing the extract A with the extract B evenly. According to the preparation method provided by the invention, the extract A is rich in alpha-linolenic acid. The polysaccharide content of the extract B is high. Compared with the purslane extract in the prior art, the purslane extract obtained by the extraction method has better antibacterial, anti-inflammatory and anti-irritation effects. |
