Centella asiatica extract and application thereof in preparation of anti-inflammatory cosmetics

The invention discloses a centella asiatica extract and application thereof in preparation of anti-inflammatory cosmetics. The method comprises the following steps: S1 taking a centella asiatica medicinal material, cleaning, drying, and crushing to 50 to 100 meshes to obtain centella asiatica powder; S2 degreasing the centella asiatica powder with an organic solvent to obtain degreased centella asiatica powder; S3 adding the degreased centella asiatica powder into a 60 to 80% ethanol solution, performing ultrasonic extraction at 65 to 80 DEG C, repeating the operation for 2 to 3 times, combining extracting solutions, performing centrifugation, and performing filtration to obtain supernate; S4 decolorizing the supernate with activated carbon, centrifuging and filtering to obtain a decolorized solution; and S5 carrying out chitosan flocculation impurity removal, centrifugation, filtration, vacuum concentration, filtration and drying on the decolored solution to obtain the centella asiatica extract.
