Problems solved by technology

However, the current natural sunscreens have a single way of sunscreening. Although some can be used for sunscreening from multiple aspects, the comprehensive sunscreening effect is not very satisfactory.

Embodiment 1

[0019] S1. Raw material formula of traditional Chinese medicine: 15 parts of chrysanthemum, 15 parts of Perilla, 15 parts of Tsao Guo, 20 parts of Poria cocos, 15 parts of sage, 20 parts of wolfberry, the above parts are parts by weight.

[0020] S2. Pulverize the above-mentioned traditional Chinese medicine raw materials, mix them evenly after passing through a 40-mesh sieve, add 7 times the volume of ethanol aqueous solution with a mass fraction of 65%, heat and reflux at 70°C for 2 extractions, each extraction for 1.5h, combine the extracts, and use Activated carbon decolorization, filtration, the filtrate is concentrated under reduced pressure to the extract, that is.

[0021] The traditional Chinese medicine extracts were tested for their ability to resist ultraviolet rays, inhibit tyrosinase activity, and scavenge superoxide anion free radicals. The determination methods are as follows:

[0022] Anti-ultraviolet measurement: Scan the Chinese medicine extract of the above...

Embodiment 2

[0037] S1. Raw material formula of traditional Chinese medicine: 8 parts of chrysanthemum, 20 parts of Perilla, 16 parts of Cao Guo, 25 parts of Poria cocos, 14 parts of sage, 17 parts of Chinese wolfberry, and the above parts are parts by weight.

[0038] S2. Grind the above-mentioned traditional Chinese medicine raw materials separately, mix them evenly after passing through a 40-mesh sieve, add 5 times the volume of ethanol aqueous solution with a mass fraction of 60%, heat and reflux at 80°C for 3 times, extract for 1 hour each time, combine the extracts, and use activated carbon Decolorize, filter, and concentrate the filtrate under reduced pressure to an extract, that is.

[0039] According to the test method of Example 1, the average ultraviolet absorption rate of the Chinese medicine extract is 94.9%, the inhibition rate of tyrosinase is 46.37%, and the free radical scavenging rate is 55.7%.

Embodiment 3

[0041] S1. Raw material formula of traditional Chinese medicine: 20 parts of chrysanthemum, 10 parts of Perilla, 13 parts of Tsao Guo, 17 parts of Poria cocos, 25 parts of Sage, 15 parts of Lycium barbarum, all the above parts are parts by weight.

[0042] S2. Grind the above-mentioned traditional Chinese medicine raw materials separately, mix them evenly after passing through a 40-mesh sieve, add 9 times the volume of ethanol aqueous solution with a mass fraction of 70%, heat and reflux at 70°C for 2 extractions, each extraction for 2 hours, combine the extracts, and use activated carbon Decolorize, filter, and concentrate the filtrate under reduced pressure to an extract, that is.

[0043] According to the test method of Example 1, the average ultraviolet absorption rate of the Chinese medicine extract is 95.3%, the inhibition rate of tyrosinase is 50.2%, and the free radical scavenging rate is 61.4%.

Abstract

The invention belongs to the technical field of cosmetics, and particularly discloses a traditional Chinese medicinal sunscreen composition as well as a preparation method and application thereof. The traditional Chinese medicinal sunscreen composition is prepared by extracting the following traditional Chinese medicinal raw materials in parts by weight: 5 to 25 parts of chrysanthemum, 10 to 20 parts of perilla leaf, 10 to 20 parts of amomum tsao-ko, 15 to 30 parts of tuckahoe, 10 to 30 parts of sage and 10 to 25 parts of medlar. The traditional Chinese medicinal sunscreen composition disclosed by the invention can be used for strongly absorbing ultraviolet rays, so an excellent sunscreen efficacy is realized; besides, the traditional Chinese medicinal sunscreen composition can be used for removing excessive free radicals caused by ultraviolet irradiation and inhibiting the activity of tyrosinase, so the efficacy of preventing the skin from being sunburnt and suntanned is realized.

Description

technical field [0001] The invention relates to the technical field of cosmetics, and more specifically relates to a traditional Chinese medicine sunscreen composition and its preparation method and application. Background technique [0002] The ultraviolet rays in sunlight are divided into three sections according to their wavelengths, short-wave ultraviolet UVC (200nm-290nm), medium-wave ultraviolet (290nm-320nm), and long-wave ultraviolet UVA (320nm-400nm). Only a very low dose of UVA and a very small dose of UVB can reach the earth, and UVC cannot reach the surface of the earth at all, so sun protection is mainly anti-UVA and UAB. UVB is the most harmful to the human body. It is the main band of photobiological effects caused by solar radiation on the skin, causing skin erythema and stimulating skin cancer cells. UVA is the most penetrating to the skin and mainly causes skin tanning. [0003] The commonly used sunscreens mainly include physical sunscreens, chemical sun...
