Lychee seed composition as well as preparation method and application thereof

The invention discloses a lychee seed composition as well as a preparation method and application thereof. The preparation method comprises the following steps: washing lychee seeds, drying and crushing for later use; adding water, heating and performing water extraction; after filtering, adding water into filter residues again for water extraction; filtering, and combining the two water extraction filtrates; concentrating the filtrate, and adding into ethanol for alcohol precipitation; and after alcohol precipitation, centrifugally separating, washing the precipitate for 2-3 times, and freeze-drying to obtain the lychee seed composition. According to the technical scheme, lychee seeds are used as raw materials, a water extraction and alcohol precipitation method is adopted for extracting the composition, the extraction process of the lychee seed composition is optimized, the product composition is obtained, the composition is applied to preparation of moisturizing masks of daily chemicals, a good effect is a
