Embodiment 1

[0040] Measure 1 g of Sophora flavescens, 34 g of bamboo leaves, 34 g of Acanthopanax fruit, and 31 g of Lycium barbarum, soak and extract once at 30°C with 20 times the amount [solution volume (ml): medicinal material weight (g)] of 80% ethanol aqueous solution, Soak for 2 hours each time to prepare an ethanol extract;

[0041] The ethanol extract was filtered and concentrated 10 times, purified with a macroporous adsorption resin, eluted with 95% ethanol aqueous solution, and collected the eluate after elution;

[0042] After the eluent is concentrated 10 times, add 3 times the volume of 1,3-butanediol, stir evenly, let stand for 24 hours, and collect the supernatant;

[0043] The supernatant is centrifuged to obtain the centrifuged supernatant, which contains the active ingredient required in the formula of the present invention, that is, the plant extract composition with whitening effect.

Embodiment 2

[0045] Measure 33g of Sophora flavescens, 34g of bamboo leaves, 32g of Acanthopanax fruit and 31g of Lycium barbarum, soak and extract 2 times at 40°C with 10 times the amount [solution volume (ml): medicinal material weight (g)] containing 10% ethanol aqueous solution, Soak for 48 hours each time to prepare an ethanol extract;

[0046] The ethanol extract was filtered and concentrated 50 times, purified with a macroporous adsorption resin, eluted with 75% ethanol aqueous solution, and collected the eluate after elution;

[0047]After the eluate is concentrated 15 times, add 0.5 times the volume of 1,3-butanediol, stir evenly, let stand for 36 hours, and collect the supernatant;

[0048] The supernatant is centrifuged to obtain the centrifuged supernatant, which contains the active ingredient required in the formula of the present invention, that is, the plant extract composition with whitening effect.

Embodiment 3

[0050] Measure 34 g of Sophora flavescens, 1 g of bamboo leaves, 33 g of Acanthopanax fruit and 32 g of Lycium barbarum, soak and extract 3 times at 50 °C with 5 times the amount [solution volume (ml): medicinal material weight (g)] containing 50% ethanol aqueous solution, Soak for 24 hours each time to prepare an ethanol extract;

[0051] The ethanol extract was filtered and concentrated 30 times, purified with a macroporous adsorption resin, eluted with 10% ethanol aqueous solution, and the eluate was collected after elution;

[0052] After the eluate is concentrated 13 times, add 1 times the volume of 1,3-butanediol, stir evenly, let stand for 12 hours, and collect the supernatant;

[0053] The supernatant is centrifuged to obtain the centrifuged supernatant, which contains the active ingredient required in the formula of the present invention, that is, the plant extract composition with whitening effect.

Abstract

The invention belongs to the field of cosmetics and specifically relates to plant extract composition with a skin whitening effect, a preparation method and application. The plant extract compositionis prepared from extracts of plants of radix sophorae flavescentis, bamboo leaf, pyracantha fortuneana fruit and fructus lycii. The plant extract composition can be applied to skin care and especiallycan be applied to skin whitening cosmetics. According to contents of all plant extracts, the content of the radix sophorae flavescentis is 1 to 34%, the content of the bamboo leaf is 1 to 34%, the content of the pyracantha fortuneana fruit is 1 to 34%, and the content of the fructus lycii is 1 to 34%. The composition compounded from the plant extracts can reduce skin melanin from varieties of ways and further has varieties of functions on the skin, so that the composition can play a skin whitening effect more effectively.

Description

technical field [0001] The invention belongs to the field of cosmetics, and specifically relates to a plant extract composition with whitening effect, a preparation method and an application. The plant composition is composed of plant Sophora flavescens, bamboo leaves, Pyracantha, and Lycium barbarum extracts, which can be used for skin care, especially Skin whitening cosmetics. Background technique [0002] Asian women have always pursued skin that is as white as fat. However, due to the influence of internal and external factors such as fast-paced work, high psychological pressure, endocrine disorders, and environmental pollution, the skin will also appear dull and pigmented, so whitening is one of the most important topics in skin care. The so-called melanin mainly refers to eumelanin and pheomelanin. Modern aesthetic medicine shows that melanin is formed through a series of oxidation reactions: the participation of three enzymes at different stages: tyrosinase, dopachr...
