Technical Field

The invention relates to the technical field of wormwood essence, and particularly relates to wormwood essence stock solution and a preparation method thereof.

Background

For the past, most of products with the effects of removing miliaria, relieving itching, preventing mosquitoes, relieving and the like aiming at skin care of infants in summer in the market adopt plant extracting solutions such as honeysuckle, wild chrysanthemum, liquorice and the like, and the extracting solutions are limited by technologies and have the problems of dark color (yellow brown or black), unpleasant smell, unstable effect and the like.

The folium Artemisiae Argyi is a Compositae plant, and has pungent, bitter, and warm nature, and enters liver, spleen, and kidney meridians. The dried leaves have effects of warming channels, stopping bleeding, dispelling cold, relieving pain, regulating menstruation, preventing miscarriage, eliminating dampness, relieving itching, dredging meridian passage, etc. The research shows that the wormwood extract has the pharmacological effects of resisting bacteria, viruses, allergy, bleeding and the like. Due to the advantages of high survival rate, easy planting and the like, the application of the wormwood and the wormwood extract can be traced to an earlier stage.

The most common uses, such as bactericidal action. Research by Song Jianyong et al in the document "Experimental observation of sterilizing effect of mugwort leaf compound disinfectant" shows that by acting a stock solution of disinfectant containing mugwort extract at 20-25 deg.C for 2-10min, more than 99.99% of various bacteria and fungi in the suspension can be killed. The disinfectant can be used for wetting the surfaces of telephone and refrigerator door handle, and can kill natural bacteria by over 99.83% after 5 min. The compound disinfectant stock solution is placed at 54 ℃ for 21 days, the effect of killing staphylococcus aureus is not obviously reduced, and the property is stable; the influence of organic matters is small; acute oral LD50 of white mouse is larger than 11000 mg-kg^-1(ii) a Skin irritation tests show that the disinfectant is free of irritation, so that the disinfectant is safe to use.

Here, the use of wormwood and its extracts for skin care products is also a current focus of research.

For example, patent CN107760489A discloses a preparation method of wormwood essence cold soap capable of clearing damp, dispelling cold, reducing swelling and resolving hard mass, which is prepared by the following steps: taking a proper amount of wormwood, adding water, decocting and filtering to obtain wormwood extract for later use; preparing alkali liquor: dissolving folium Artemisiae Argyi extract in pure water, and mixing alkali with the water phase mixture until alkali is completely dissolved; (III) preparing grease; (IV) mixing alkali oil: mixing the grease with the alkali liquor, and rapidly stirring clockwise; (V) pouring the film; and (VI) demolding. The essence cold soap disclosed by the invention can thoroughly clean skin and pores; the extracted and concentrated wormwood essence acts on the thoroughly cleaned skin surface, and can effectively eliminate dampness, remove rash, remove miliaria, sterilize and relieve itching through transdermal absorption; can effectively reduce the pigmentation of the face, lighten the black spots of the face, improve acne, expel toxin and beautify the face; after long-term use, the skin care product can eliminate dampness and dispel cold, reduce swelling and eliminate stagnation, improve the skin condition and enable the skin to be more moist and fresh.

Of course, the use of mugwort extract for the prevention of mosquito bites has also been suggested. For example, patent CN104224598A discloses an folium artemisiae argyi extract essence for preventing mosquito bite of infants, which mainly comprises folium artemisiae argyi extract essence, folium eucalypti globueli extract essence, pinus sylvestris extract, flos lonicerae extract, flos chrysanthemi indici extract, elemi, mint, juniper berry extract, and vitamin B1; through mixing, sealing, soaking, stirring, extracting, purifying and other steps. The essence extracted from pure natural plants is compounded, so that the wormwood essence is extracted for preventing mosquito bites of infants, the eucalyptus leaf extract essence and the pinus sylvestris extract are fused, the skin health of infants is improved, the infants are cooled, detoxified and prevented from biting, and the wormwood essence is particularly suitable for newborn infants, calms and soothes, prevents various skin discomfort in links, and is also suitable for pregnant and lying-in women. However, the mosquito bite preventing agent is added with a large amount of mint, so that the odor is heavy and the infant is relatively rejected.

In addition, the folium artemisiae argyi extract in the above-disclosed folium artemisiae argyi-containing products is prepared by a conventional extraction process, and most of the folium artemisiae argyi extract contains stable flavonoids and polysaccharides, but the content of volatile components is low. In order to exert the efficacy and effect of the wormwood to the maximum extent and improve the utilization value of the wormwood, the preparation of the wormwood product containing volatile components and stable components is the key point of current enterprise research and development.
