Embodiment 1

[0095] Embodiment 1: the preparation of kudzu root extract

[0096] The kudzu root was sufficiently dried and finely chopped, and then 100 g of the dry weight was placed in a flask and extracted by cold immersion in 1000 g of an extraction solvent (distilled water) for 3 days. The extract after the cold soaking was filtered through a filter having a pore size of 0.2 μm to prepare a kudzu root extract.

Embodiment 2

[0097] Embodiment 2: the preparation of kudzu root flower extract

[0098] The Pueraria lobata flower and flower buds were fully dried and finely chopped, and then 100 g of the dried weight was placed in a flask and cooled for 3 days with 1000 g of an extraction solvent (distilled water) to perform extraction. The extract after the cold soaking was filtered through a filter having a pore size of 0.2 μm to prepare a kudzu root flower extract.

Embodiment 3

[0099] Embodiment 3: the preparation of compound

[0100] There is no particular limitation on the way to obtain compounds 1 to 3, which can be chemically synthesized according to methods known in the art or commercially available substances can be used for experiments.

Abstract

The present invention relates to a composition for improving skin comprising an extract of Pueraria thomsonii or a compound derived therefrom. The composition provided by the invention has excellent effects of reducing melanin, resisting inflammation, promoting collagen synthesis and anti-glycation, and can be effectively used for skin whitening, acne improvement, skin elasticity enhancement or wrinkle improvement, oxidation resistance, and skin moisturizing. Therefore, the composition of the present invention can be used as a cosmetic composition, a food composition, and a pharmaceutical external composition which are safe to the skin and have an excellent effect of improving the state of the skin.

Description

technical field [0001] The present invention relates to a cosmetic composition, a food composition, or a quasi-drug composition comprising an extract of Pueraria lobata or Pueraria lobata, or a compound derived from the extract, as an active ingredient. [0002] Specifically, it relates to a composition for skin whitening, acne improvement, skin elasticity enhancement or wrinkle improvement, antioxidation, or skin moisturizing, which contains the above-mentioned substance as an active ingredient. Background technique [0003] The color of human skin depends on various factors such as the activity of melanocytes, the distribution of blood vessels, the thickness of the skin, and the presence or absence of pigments in and out of the human body. In particular, the presence of tyrosinase in melanocytes The black pigment called melanin, which is produced by the action of enzymes such as cyanide, is very important. Melanin exists in the skin and plays an important role in protecti...
