Problems solved by technology

However, the boiling method requires a longer extraction time and lower production efficiency
The solvent method requires the use of some organic solvents such as carbon dichloride, which are likely to remain in the sample, so it is obviously not suitable to be used as a functional raw material for cosmetics
Supercritical extraction is a high-tech extraction method, but the production cost is high

Embodiment 1

[0047] A preparation method of cinnamon bark extract, comprising the following steps:

[0048] (1) The cinnamon bark is pulverized by a traditional Chinese medicine grinder, passed through a 60-mesh sieve, and dried at 45° C. to constant weight to obtain cinnamon bark powder;

[0049] (2) Mix the cinnamon bark powder with ether (the mass ratio of cinnamon bark powder: ether is 1:60), stir for 1 hour, filter, and dry the filter residue at 45°C to constant weight to obtain degreased cinnamon bark powder; Diethyl ether in the filtrate is recovered and reused by distillation;

[0050] (3) In a container, mix 120mL of 40% by volume ethanol aqueous solution with 3.0g of degreased cinnamon bark powder, seal it, conduct ultrasonic extraction with 400W ultrasonic power at 40°C for 1h, filter, and let the filtrate stand for stratification , take off the lower layer clear night, obtain the crude extract of cinnamon bark; the content of tannic acid in the crude extract of cinnamon bark i...

Abstract

The invention belongs to the technical field of cosmetics, and discloses a cassia bark extract and a preparation method thereof and an application of the cassia bark extract to cosmetics. The method comprises: (1) degreasing cassia bark powder with a solvent, performing filtration, and drying the filtered residue to obtain degreased cassia bark powder; (3) mixing an ethanol aqueous solution with the degreased cassia bark powder, performing ultrasonic extraction and filtering, allowing the filtrate to stand, taking the subnatant out, and performing vacuum concentration and freeze-drying treatment to obtain a powdery cassia bark coarse extract; and (5) dissolving the cassia bark coarse extract with an ethanol aqueous solution having the volume fraction being 5-15%, performing purification with a macroporous resin gel column, performing elution with an ethanol aqueous solution having the volume fraction being 30-90%, and performing vacuum concentration and freeze-drying to obtain the purified cassia bark extract. The obtained cassia bark extract is high in extraction rate and good in oxidation resistance and whitening effect, and can be used as an anti-aging or a whitening agent in cosmetics.
