Problems solved by technology

As far as the current general separation and preparation methods are concerned, they mainly rely on traditional thin-layer chromatography and column chromatography to separate and prepare, but the separation capacity of thin-layer chromatography is very low, and the separation effect of column chromatography is not high, especially in the separation process. Using a large amount of organic solvents pollutes the environment and wastes costs, and the extraction time is not economical

Abstract

The invention provides a method for preparing a camellia extract and its application. The method comprises the following steps: A. selecting fresh, non-damaged and disease-free camellias, and drying them by adopting a refraction window drying technique to obtain dried camellia products; B. After the dried product of camellia is ultrafinely pulverized and sieved by airflow, it is added into a quaternary system deep eutectic solvent for ultrasonic extraction to obtain an extraction mixture; C. Mix the extraction mixture with deionized water, adjust the pH, and then add enzymes for enzyme solution; D, after enzymolysis, place it for a certain period of time, and then filter to obtain the camellia extract. The method adopts the refraction window drying technology for drying, ultrafine pulverization, and uses non-toxic deep eutectic solvent as the extraction agent. The production process is simple, efficient, safe and green; it overcomes the need for a large amount of toxic organic solvents and Complex column separation process. The obtained extract has skin repairing effect, antibacterial effect, strong antioxidant capacity and is safe and non-irritating.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and relates to a preparation method and application of a camellia extract. The obtained extract has skin repairing and antibacterial effects. Background technique [0002] Epicatechin belongs to catechins, and catechins are important phenolic substances. In addition to tocopherol, ascorbic acid, carotenoids, and alkaloids among the natural antioxidant components in plants, phenolic substances are the most widely distributed, most diverse and most abundant components. Studies have shown that epicatechin has a variety of biological activities such as scavenging free radicals, inhibiting tumors, anti-mutagenesis, anti-virus, inhibiting microorganisms, reducing fat and helping digestion, skin care and beauty. [0003] Epicatechin is insoluble in water, and traditional extraction methods often use organic solvents (such as methanol, ethanol, ethyl acetate, chloroform, n-butanol, et...
