Embodiment 1

[0034] Embodiment 1: A kind of preparation method of natural material whitening composition

[0035] (1) Preparation of mountain cherry extract

[0036] Take 5g of fresh mountain cherry pulp, put it in a round bottom flask, add 75ml of 70% ethanol, heat and reflux in an electric heating mantle at 90°C for 1.5h, filter the filtrate, recover ethanol with a rotary evaporator, concentrate to 2g / ml for extraction solution, add 3% powdered activated carbon, and decolorize by ultrasonic vibration at pH 3.0 and 60°C for 30 minutes to obtain the extract of mountain cherry.

[0037] (2) Preparation of Salvia Leaf Extract

[0038] Take 5g of fresh Salvia miltiorrhiza leaves, add 60ml and 40ml of water respectively, decoct on the electric stove twice, each time for 1h, filter and combine the filtrate, concentrate to a certain volume, add 3 times the amount of 60% ethanol and let it stand for 24h, filter the filtrate, and recover the ethanol , concentrated to 1g / ml, that is the extract o...

Embodiment 2

[0042] Example 2: Determination of tyrosinase inhibition rate of natural material whitening composition

[0043] 1. Test material

[0044]Levodopa (L-DA), purchased from Shanghai Jinsui Biotechnology Co., Ltd.;

[0045] L-tyrosine was purchased from Shanghai Jinsui Biotechnology Co., Ltd.;

[0046] The mountain cherry extract, salvia miltiorrhiza leaf extract, Agrimony extract and natural substance whitening composition prepared in the above embodiments.

[0047] 2. Test method

[0048] Using L-DA as substrate, detect tyrosinase activity. Take 2ml of the solution to be tested, add 2ml of 0.075% L-dopa reaction solution and mix with 2ml of tyrosinase (200IU), immediately place it on a spectrophotometer to measure the absorption value at a wavelength of 475nm, record continuously for 20min, and obtain the product- time curve. With pH6.8 phosphate buffer as blank control, the same method is used to measure, and the tyrosinase activity inhibition rate is calculated according ...

Abstract

The invention relates to a natural substance composition and application of the same in a whitening cosmetic. The natural substance composition is composed of extracted essence of Manchu cherry, extracted essence of red-rooted salvia leaf and hairyvein agrimony extract in a ratio of 3-5 to 2-6 to 1-5. The composition has substantial inhibitory effect on the activity of tyrosinase, so the composition can inhibit formation of melanin; and the composition can be added into the whitening cosmetic according to a mass percentage of 1 to 10%, and the composition is natural, nontoxic and non-irritant and makes skin to be white and glossy.

Description

technical field [0001] The invention relates to a natural material composition, more specifically to a composition of mountain cherry extract, salvia leaf extract and Agrimony extract and its application in whitening cosmetics, belonging to the field of cosmetics. Background technique [0002] Because of the traditional beauty concept of "one white covers one hundred ugliness", oriental women have never stopped pursuing whitening. A report on the whitening status of Asian women shows that 80% of Asian women dream of having whitening skin, and more than 60% of women use whitening products.
