By adopting the technical scheme, the active ingredients in the cellular fluid of the kapok are extracted from the kapok through the ethanol water solution by taking the kapok fresh flowers as the raw materials, wherein the active ingredients comprise anthocyanin, volatile oil, bioactive water and the like, so that the extract has the fresh fragrance of the kapok, and has the effects of moisturizing, diminishing inflammation and relieving skin.

The preparation method has no sun drying process or concentration drying and solvent removing purification process, and retains anthocyanidin, volatile oil and other active ingredients in flos Bombacis Malabarici to the maximum extent.

In addition, the preparation method directly uses the ethanol water solution as an effective component in the extract, so that the extract is deeply disinfected, viruses and bacteria are effectively killed, an additional high-temperature sterilization and disinfection process is saved, the extract has an antiseptic function, and can be stored for a long time without deterioration; the ethanol water solution with the mass concentration of 70-80% is selected, the disinfection effect in the concentration range is excellent, if the concentration is too low, the disinfection effect cannot be achieved, if the concentration is too high, the disinfection effect can also be influenced, because the surface of a pathogen is instantaneously denatured to form a protein protective layer when the concentration of the ethanol is too high, the ethanol cannot enter the body of the pathogen to influence the disinfection effect, and in addition, after the concentration of the ethanol exceeds 80%, a protective film can be formed on the plant cell wall or cell membrane to prevent active substances from dissolving out, so the ethanol solution with the concentration of 70-80% is selected to improve the extraction rate.

Detailed Description

Because fresh kapok is easy to contain worm eggs and germs, the kapok can be used as a medicinal material in the form of dry flowers, the dry flowers of the kapok are generally adopted as raw materials in the existing preparation method of the kapok extract, and the dry flowers need to be subjected to a high-temperature sun-drying or drying process. The inventors have found that the active ingredients in kapok are sensitive to heat, such as anthocyanins, volatile oils and bioactive moisture in kapok.

The anthocyanidin has antioxidant and free radical scavenging effects, and can inhibit inflammation and prevent allergy; the kapok volatile oil contains alcohols such as 4-hydroxy-2-butanone, dodecanal, tetradecanoic acid and heptyl acetate, aldehydes, acids, phenols, propiophenones, terpenes and other active substances, and has the effects of moisturizing and diminishing inflammation; the bioactive water comprises free water and absorbed water, and is also helpful for moisturizing the skin. However, the structure of the anthocyanidin is damaged after heating, volatile oil is easy to volatilize and run off in the sun-curing or drying process, and bioactive moisture is also volatilized in the drying process and the concentrating process, so that the loss caused by the fact that the active ingredients originally possessed by the kapok are not applied by taking the dried flowers as the raw materials, and the effects of moisturizing and relieving the kapok are neglected.

Based on the defects, through a great deal of research, the inventor finally creatively adopts a mode of directly extracting the fresh kapok flowers by using the ethanol water solution, so that the active ingredients of the kapok are reserved to the greatest extent, the kapok extract with the effects of moisturizing and relieving is obtained, and the ethanol water solution is directly used as the component part of the kapok extract, so that ova and germs in the kapok can be effectively killed, and the quality guarantee period of the kapok extract is prolonged.
