Method for extracting carthamin yellow from safflower carthamus

The invention relates to a method for extracting carthamin yellow from safflower carthamus and in particular relates to a method combining a flash extraction technology with an enzymolysis process. The method comprises the following steps: a, putting safflower carthamus subjected to impurity removal into a container, adding an ethanol solution, and crushing the safflower carthamus on a traditional Chinese medicine extractor for extraction; b, adjusting the pH value of extraction liquid to be 4.5-5.5, adding cellulose which accounts for 0.3wt%-0.5wt% of the raw material, and performing enzymolysis at 40-60 DEG C for 2.0-3.0 hours; c, inactivating at the high temperature; d, adjusting the pH value of the solution to be 7, filtering, and performing reduced pressure concentration; e, purifying concentrated liquid by adopting macroporous adsorption resin, eluting by an ethanol solution, and collecting eluate; and f, performing reduced pressure concentration and spray-drying to obtain carthamin yellow. According to the method, the safflower carthamus is adopted as the raw material, the flash extraction and enzymolysis combined process is fully utilized, carthamin yellow in the safflower carthamus is dissolved out to the maximum extent, the extraction time is greatly shortened, the cost is relatively low, the environment is well protected, and the industrial production is facilitated.

Oil-control and hair loss-prevention composition, oil-control and hair loss-prevention product and preparation method of oil-control and hair loss-prevention product

The invention provides a composition for controlling oil and preventing hair loss. The composition is prepared from fructus lycii, fructus ligustri lucidi, fructus tribuli and lotus seeds. The composition further comprises one or more of carthamin yellow, emodin and gingerol. The carthamin yellow can promote blood circulation and improve the hair follicle environment; the composition comprises carthamin yellow, emodin and gingerol, the carthamin yellow can inhibit 5 alpha-reductase and excessive secretion of male hormone, the gingerol can resist bacteria and diminish inflammation, inhibit dandruff growth and prevent alopecia/hair growth, and when the content of the carthamin yellow in the composition is 1-10%, the content of the emodin is 0.05-0.3% and the content of the gingerol is 0.2-3%, the content of the carthamin yellow in the composition is 0.05-0.3%, and the content of the gingerol in the composition is 0.05-0.3%. The composition for controlling oil and preventing alopecia can reduce the concentration of dihydrotestosterone, eliminate cell inflammation, regulate the resting period of hair follicles, control oil, prevent alopecia, promote growth, promote scalp blood microcirculation, improve the hair follicle environment, nourish hair roots and improve the allergic reaction of independent substances to the skin by reducing the concentration of dihydrotestosterone. The oil control, hair loss prevention and hair growth effects are jointly and synergistically completed through the composition in a specific proportion.
