Oriental cherry flower extract and extraction method and application thereof

Abstract

The invention provides an oriental cherry flower extract and an extraction method and application thereof. The extraction method comprises the following steps: extracting oriental cherry petals by adopting an extracting agent to obtain the oriental cherry flower extract, wherein the extracting agent comprises a composition of C3-C6 small molecular polyhydric alcohols, ethanol and water. The extraction method is simple in process route, large-scale industrial application is easily realized, and the obtained oriental cherry flower extract contains rich high-activity active ingredients, has an excellent hair-blacking effect, can be applied to hair-blacking cosmetics of multiple dosage forms such as aqueous solution and emulsion and is wide in application range. The oriental cherry flower extract is mild and non-irritating, is capable of activating tyrosinase, repairing damaged melanocytes and promoting growth of the melanocytes and generation of melanin, regulation and repair are performed from a melanin formation pathway, the aims of blacking hair and improving gray hair and white hair are achieved, the hair can be effectively blacked after the oriental cherry flower extract is usedfor 15 days, and the oriental cherry flower extract has excellent effects.

Description

technical field [0001] The invention belongs to the technical field of plant extracts, and in particular relates to a cherry blossom flower extract and its extraction method and application. Background technique [0002] Cherry blossoms are deciduous trees of the family Rosaceae, also known as mountain cherry blossoms, Fukushima cherry blossoms, black wild cherry blossoms, or blue-skinned cherry blossoms. They are umbel-shaped, not only have high ornamental value, but also can extract cherry blossom pigments from petals for food processing , and has a variety of medicinal value. Cherry blossom leaves and cherry blossoms are traditional Chinese medicinal materials, which have the functions of relieving cough, relieving asthma, moistening intestines and hangover. In recent years, cherry blossom extract has been widely used in cosmetics as a skin conditioner to exert its effect. [0003] Cherry blossom is a cosmetic plant raw material, and the extracts of its flowers, bark and...

AI Technical Summary

Problems solved by technology

The preparation method is simple and easy to operate, can effectively extract cherry blossom polysaccharide components, has a significant antioxidant effect, and can be used for pharmaceutical preparation; however, this method can only obtain cherry blossom polysaccharides, and the extraction effect of other functional components in cherry blossom petals is relatively low. Difference

[0006] CN1572755A discloses a cherry tree leaf extract and a preparation method thereof, the preparation method comprising: putting dried cherry leaf powder into an extraction container, adding a content of 70 ~99.7% ethanol, carry out continuous stirring and extraction, the solution obtained by extraction is separated and concentrated to obtain the cherry leaf extract, which can be used in pharmaceuticals, health products, cosmetics, food and wine; however, the preparation method The extraction efficiency is not high, resulting in waste of plant raw materials, and the extraction is carried out with ethanol with a content of 70-99.7%, and the prepared cherry tree leaf extract is less polar, which is difficult to apply to water-based products, and the application range is narrow

This extraction method has little damage to the functional components and good extraction effect, but the extraction kettle and supercritical carbon dioxide used in the extraction method are not easy to obtain, which greatly increases the extraction cost of the active components of cherry blossoms

[0008] The cherry blossom extract preparation process disclosed in the prior art still faces the problems of poor extraction effect and low utilization of plant raw materials, and a large amount of waste liquid will be generated during the extraction process. Further increase the preparation cost; while the supercritical carbon dioxide extraction method relies on complex equipment and high-cost extraction agents, and the process route is complicated, which is also not conducive to the large-scale preparation of cherry blossom extracts

More importantly, the existing extraction process cannot obtain multi-category, high-activity, and wide-ranging active ingredients, resulting in the efficacy of cherry blossom extracts failing to meet the application requirements in cosmetics
