Description

Plant composition and preparation method and application thereof

Technical Field

The invention relates to the field of plant extraction research, and particularly relates to a plant composition and a preparation method and application thereof.

Background

The bidirectional fermentation of Chinese medicine is a new high-tech Chinese medicine preparing technology combining modern microbial engineering with the research result of microecology. The 'bidirectional fermentation' is characterized in that traditional Chinese medicinal materials or herb residues with certain active ingredients are used as a medicinal substrate to replace a traditional nutrient substrate, and optimized strains are added into the medicinal substrate for microbial transformation, so that a fermented composition formed by the medicinal materials or herb residues is called medicinal mycoplasm. The bidirectional property is realized in that the medicinal matrix provides nutrition required by fungi, and simultaneously is influenced by enzymes in the fungi to change self tissues and components to generate new flavor functions. Therefore, the microbial fermentation of the traditional Chinese medicine is environment-friendly, high in extraction efficiency and good in effect, can be applied to multiple industries such as food and medicines, but is less in application in cosmetics, can provide a way for expanding new components and new effects in the field of cosmetic raw materials, and has a very wide application prospect.

The patent (CN 107898931A) discloses a regulator of clock gene expression and a preparation method thereof, wherein the regulator is a dendrobium extract. The dendrobium extract is found to promote the expression of Clock gene for the first time. However, studies (Sun, BMAL1/CLOCK regulation of keratinocyte apoptosis, DNA damage and immunity under UVB irradiation [ D ]. Tianjin university, 2018.) show that (i) under normal culture conditions without UV irradiation, small RNA-mediated silencing of CLOCK gene can promote keratinocyte proliferation and induce differentiation of primary keratinocytes; secondly, the silencing of the Clock gene can prevent the apoptosis of primary keratinocytes and HaCat cells caused by UVB; thirdly, in keratinocytes, silencing Clock can effectively inhibit the high expression of the cell factor caused by UVB; in primary keratinocytes, Clock gene silencing strongly inhibited the increase in total p53 protein and phosphorylation caused by UVB. In conclusion, the promotion of Clock can cause adverse reaction on skin, inhibit the expression of Clock gene, and effectively reduce keratinocyte apoptosis and resist the adverse reaction of UVB on organisms.

Aiming at the fact that the single dendrobium extract promotes the expression of Clock gene and the adverse reaction on skin, it is necessary to develop a plant composition which has high active ingredient content, can inhibit non-enzymatic glycosylation reaction, inhibit the expression of Clock gene and inhibit the activity of tyrosinase, and has the effects of resisting aging and whitening skin.

2. Non-enzymatic glycosylation assay

One of the main features of skin aging is skin yellowing and the appearance of age spots, mainly due to lipid peroxidation and non-enzymatic glycosylation reactions. The non-enzymatic glycosylation reaction in organisms refers to that under the condition of no enzyme catalysis, the aldehyde group or ketone group of reducing sugar and the amino group of macromolecules such as protein and the like undergo Maillard reaction to generate yellow brown glycosylation end products (AGEs).

By inhibiting the nonenzymatic glycosylation of proteins, the inhibitory effect of substances on the deposition of brown pigment can be reflected. The specific test method is as follows:

0.5mol/L bovine serum albumin solution (BCA) and 20mg/mL fructose solution are mixed in equal volume to obtain BCA-fructose reaction solution. The reagents were added sequentially in the order of Table 7 and mixed by vortexing after addition. After incubation for 5 days at 37 ℃ in the dark, the fluorescence intensity was measured at an excitation wavelength of 370nm and an emission wavelength of 440 nm. The inhibition degree of the sample to be tested on the non-enzymatic glycosylation reaction is calculated according to the Fluorescence intensity (RFU, Relative Fluorescence Unit), and is shown in the formula (1).

3. Inhibition of tyrosinase assay

Skin pigmentation is caused by the accumulation of melanin in the epidermis, and excessive melanin synthesis causes skin pigmentation, formation of spots, and dullness of the skin. Generally, the higher the tyrosinase activity, the more melanin synthesis. By inhibiting tyrosinase activity, the rate of melanin synthesis can be controlled. The whitening effect of the substances applied to cosmetics was evaluated by the tyrosinase activity inhibition rate, and the experimental reaction system is shown in table 8. After the sample addition, incubation was carried out at 25 ℃ for 30min, and the absorbance was measured at 475 nm.
