This invention relates to a *
Truffle* extract with repairing effects and its applications, belonging to the field of
plant extraction technology. The *
Truffle* extract is prepared by a method comprising the following steps:
reflux extraction of *
Truffle*
raw material, concentration of the extract,
alcohol precipitation of the concentrate,
filtration, resolution, low-temperature water
precipitation,
centrifugation to collect the supernatant, and concentration and
drying to obtain the *Truffle* extract. In this invention, the innovative use of a three-step extraction method of "
water extraction-
alcohol precipitation-low-temperature water precipitation" results in a synergistic effect, effectively promoting the release and
dissolution of relevant active ingredients in *Truffle*, significantly increasing the content and purity of polysaccharides in the extract, and significantly enhancing its repairing effects. Simultaneously, this extract also possesses moisturizing, soothing, firming, and nourishing effects, making it suitable for preparing
cosmetics with these effects.
