Abstract

The invention belongs to the technical field of extraction of Chinese herbal medicine, and particularly relates to a herba centellae extract with anti-inflammation and anti-sensitivity effects. The herba centellae extract is prepared by adopting the following preparation method: S1. adding ethanol into herba centellae powder for extraction, carrying out ultrasonic assisted extraction, then centrifuging or filtering, and collecting a filtrate; S2. adding activated carbon to the filtrate obtained in step 1 for decoloring, centrifuging, and collecting a decolored filtrate; S3. concentrating the decolored filtrated obtained in step 2, adding a chitosan liquid for decontamination, filtering, and collecting a decontaminated filtrate; S4. adding macroporous adsorption resin to the decontaminated filtrate for purification, and eluting with ethanol to obtain an eluent; S5. concentrating, desalting and drying the eluent obtained in step 4 to obtain the herba centellae extract, wherein in S1, the concentration of ethanol is 60-90%, the ultrasonic power is 228W-380W, and the material-to-liquid ratio is 1:20-80. The herba centellae extract provided by the invention has remarkable anti-inflammation and anti-sensitivity effects, is prominent in oxidation resistant and free radical removal effects, and can be widely applied to skin care products with anti-inflammation and anti-sensitivity effects.
