The invention provides a preparation method of a
purslane extract as well as a product and application of the
purslane extract, and belongs to the technical field of
cosmetics. The preparation method comprises the following steps: (1) preparing purslane
powder; (2) performing ultrasonic-assisted extraction on the
mixed solution, and filtering to obtain filtrate 1 and filter residues; (3) performing enzymolysis extraction, and filtering to obtain filtrate 2; (4) mixing the filtrate 1 and the filtrate 2, adding a
clarifying agent, stirring, standing and filtering to obtain an extracting solution; and (5) decoloring the obtained extracting solution, carrying out rotary
evaporation concentration, and freeze-
drying to obtain the
purslane extract. The
portulaca oleracea extract obtained by the method provided by the invention is high in yield, relatively high in total flavone and total
polyphenol content and extremely low in
protein content, so that the
portulaca oleracea extract has better anti-inflammatory and anti-
allergy effects, can better relieve
skin inflammation when being used in
cosmetics, and achieves the anti-inflammatory, repairing and soothing effects.
