The magnolia officinalis total phenol derivative prepared by the invention has good water solubility, is colorless and transparent after being dissolved, has obvious inhibition effect on common gram-negative bacteria, gram-positive bacteria, fungi and the like, and can be used as a green natural preservative to be applied to the fields of foods, medicines, cosmetics and the like.
Description
Technical Field
The invention relates to the field of magnolia officinalis total phenol derivatives, in particular to a composition of magnolia officinalis total phenol derivatives and a preparation method and application thereof.
Background
The food, the medicine and the cosmetics are rich in a large amount of water and various nutritional ingredients, a good growth environment is provided for microorganisms, and the microorganisms are difficult to invade in the production and use processes of the cosmetics, so that the cosmetics are extremely easy to decay, the quality of the products is reduced, and the health of users is threatened. The addition of preservative in cosmetics is an important means for protecting products from microbial contamination, prolonging the shelf life of the products and ensuring the safety of the products.
Currently, many kinds of preservatives are used in foods, medicines and cosmetics, most of them are chemical preservatives, and dozens of them are commonly used, including acidic preservatives (benzoic acid), ester-type preservatives (parabens) and the like. However, with the development of science and the increasing awareness of consumer safety, it is gradually discovered that some chemical preservatives have adverse effects on the human body, cause skin allergy, decrease in physical functions, and cause environmental pollution, although the preservative effect of the chemical preservatives is good. Therefore, natural preservatives are urgently needed by various industries, and a natural preservative with low toxicity, low irritation and high performance has great significance in the fields of food, medicines, cosmetics and the like.
Cortex magnoliae officinalis (Magnolia officinalis cortex) is dried bark, root bark and branch of Magnolia officinalis wils, belonging to important traditional Chinese medicinal materials and is listed as a high-quality product in the Shennong herbal classic. Cortex Magnolia officinalis is bitter and pungent, and warm in nature, and has effects of activating qi-flowing, eliminating dampness, warming spleen and stomach, relieving pain, lowering adverse qi, and relieving asthma. The main chemical active ingredients of the magnolia officinalis are lignans, magnolol, honokiol and the like. The phenols in cortex Magnolia officinalis have antibacterial, antitumor, analgesic, and antiinflammatory effects. But because the water solubility is poor, the mangnolia officinalis total phenols are easy to oxidize and deteriorate, and the application of the mangnolia officinalis total phenols in foods, medicines and cosmetics is greatly hindered. Generally, the general surface active agent and the emulsifier can be used for solubilizing the total magnolol, and in this case, the dosage of the required surface active agent and the required emulsifier is very large, and even if the total magnolol is applied to an aqueous formulation, the total magnolol can be separated out from the aqueous formulation, so that the whole system becomes white and turbid, and the use is seriously influenced. In addition, a small amount of alkali can be added into a formula system to change the total phenols of the magnolia officinalis into salts and increase the water solubility of the total phenols of the magnolia officinalis, and the total phenols of the magnolia officinalis formed by the method are extremely unstable and easily become golden yellow, so that the conductivity of the system is increased and the bacteriostatic ability is reduced. The above method has very high requirements on the pH of a product formula system and the dosage accuracy of a thickener and an emulsifier, so that the method is basically difficult to process and apply.
The traditional method for improving the solubility of the total phenols of the magnolia officinalis introduces impurity compounds into a protosystem, and enables the thick total phenols to be unstable after being dissolved in an aqueous agent system, so that the system is easy to deteriorate, and the bacteriostatic ability is reduced. Therefore, the modification of the structure of the total phenols of the magnolia officinalis improves the solubility and the bacteriostatic ability of the total phenols of the magnolia officinalis in water, and is a problem to be solved urgently when the total phenols of the magnolia officinalis are used as natural preservatives to be applied to foods, medicines and cosmetics.

TABLE 4
TABLE 5
As can be seen from the results in Table 1, in the solubility qualitative test, the solubility of the magnolia officinalis total phenol derivative prepared by the invention in 100g of solvent water is more than 1g, namely, the sample prepared in the example is completely dissolved, while the magnolia officinalis total phenol extracted from the plant is not soluble in water; the data in table 3 show that the magnolia total phenol derivative prepared in example 3 has significant bacteriostatic action on escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, candida albicans and aspergillus niger, and the bacteriostatic effect is superior to that of the traditional chemical preservatives, namely methyl paraben and phenoxyethanol; the spray formulation of Table 4 provides a very suitable environment for the survival of bacteria and fungi, and it can be seen from the data in Table 5 that under such harsh conditions, the sample prepared in example 3 of the present invention exhibited excellent bacteriostatic ability, as tested by the preservative challenge test for the 28 day spray formulation, and the Magnolia bark total phenol derivative in example 3 as a preservative passed the preservative challenge test.
Because the total phenol of the magnolia officinalis is not dissolved in water, the bacteriostatic effect is difficult to test. The 10% magnolia officinalis total phenol ethanol solution has a good antibacterial effect, but the national standard has strict limitation on the dosage of ethanol in cosmetics, and when the magnolia officinalis total phenol ethanol solution is applied to a water system, magnolol and honokiol can be separated out from ethanol, so that the magnolia officinalis total phenol ethanol solution cannot be applied industrially.
The magnolia officinalis total phenol derivative obtained by modifying the magnolia officinalis total phenol by adopting the method has good water solubility, and the solubility of the magnolia officinalis total phenol in water is effectively improved; the magnolia officinalis total phenol derivative has obvious inhibition effect on common gram-negative bacteria, gram-positive bacteria, fungi and the like.
The preferred embodiments of the present invention have been described above in detail, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention, including combinations of various technical features in any other suitable way, and these simple modifications and combinations should also be regarded as the disclosure of the invention, and all fall within the scope of the invention.
