Description

Callus culture medium and extract of rosa tenuifolia, preparation method and application
Technical Field
The invention relates to a callus culture medium and extract of rosa tenuifolia, a preparation method and application thereof.
Background
Plant callus cells are widely applied to the industries of foods, medicines and cosmetics due to the abundant secondary metabolites, naturalness, environmental friendliness and controllable conditions. Taxol, an anticancer component obtained by using plant cell culture technology, was approved by FDA in 2000, and apple stem cells were used by many cosmetic brands for their cell protection function. The plant extracts of Rosaceae are used in foods and cosmetics, and have effects of improving skin color, regulating water-oil balance, and enhancing skin activity. The rosa tenuifolia (Rosa graciliflora Red. Et Wils) is a scarce rosaceae plant resource, is mainly distributed in the partial areas of Yunnan, sichuan, tibet and Shaanxi, and the roots and fruits of the rosa tenuifolia can be used as medicines, have the effects of improving immunity, converging and detumescence, and are rosa tenuifolia which is worthy of attention and development.
In recent years, various documents report that vitamin C, nicotinamide, tranexamic acid and hydroxypropyl tetrahydropyran triol have the effects of whitening skin, protecting skin cells, brightening skin color and the like, and are widely applied to cosmetic products. Studies show that vitamin C has the functions of resisting oxidation and assisting collagen synthesis in human skin, and can resist aging, reduce wrinkles, inhibit melanin generation and the like. The nicotinamide has the effects of inhibiting skin surface pigmentation and whitening skin, and the whitening mechanism is possibly related to the inhibition of transfer of melanosomes from melanocytes to keratinocytes, so that the nicotinamide can reduce percutaneous moisture loss, reduce sebum secretion, enhance skin barrier function, increase the cohesiveness and thickness of stratum corneum and increase the maturity of the stratum corneum when the nicotinamide is externally used. Tranexamic acid, also known as tranexamic acid, is a plasmin inhibitor that is associated with abnormal fibrinolysis and is able to reduce blood loss, in theory any damage to the formation of the stratum corneum may cause hyperpigmentation by the PA activation system, whereas tranexamic acid may inhibit the synthesis of melanin by inhibiting PA. Hydroxypropyl tetrahydropyran triol is a derivative of xylose extracted and separated from beech tree, and has the main effects of promoting synthesis of mucopolysaccharide and proteoglycan, promoting synthesis of collagen, restoring dermis-epidermis connection in aged skin, helping dermis maintain elasticity and promoting regeneration of damaged tissues. The functional components of the cosmetics are widely applied in the cosmetic industry at home and abroad, and are popular in recent years. However, no report on the use of the components for callus culture is available at home and abroad.

1. Effect of the extracts of Rosa tenuifolia cells obtained from different combinations of media on the free radical scavenging Rate
1, 1-diphenyl-2-trinitrophenylhydrazine (DPPH) is a stable nitrogen-centered organic radical. DPPH method was proposed in 1958 and is widely used to measure the anti-aging capacity of biological samples, classified substances and foods. The method is based on the fact that DPPH free radical has single electron, has strong absorption at 517nm, and the alcohol solution is purple. When the free radical scavenger exists, the free radical scavenger is paired with single electron to make its absorption gradually disappear, and its fading degree is quantitatively related to the number of electrons accepted by the free radical scavenger, so that a spectrophotometer can be used for quick quantitative analysis to detect the free radical scavenger, thereby evaluating the anti-aging capability of the sample.
Adding 0.1mL of extract sample solution into a test tube, adding 0.1mL of DPPH ethanol solution, mixing, reacting at room temperature in dark place for 30min at room temperature in dark place, measuring OD value at 525nm, and calculating clearance according to the following formula: clearance I (%) = [1- (T-T0)/(C-C0) ] ×100%, wherein: t0: absorbance of 0.1mL sample solution plus 0.1mL 95% ethanol; t: absorbance of 0.1mL sample solution plus 0.1mL ldpph solution; c0: absorbance of 0.1mL water plus 0.1mL 95% ethanol; c: absorbance of 0.1mL water plus 0.1mL DPPH solution.
As is clear from the results in Table 7, the DPPH clearance of the cell extracts of Rosa tenuifolia in examples 1 to 4 and examples 6, 10, 15 and 17 was lower than that of the control group.
TABLE 7 DPPH clearance of different cell extracts of Rosa tenuifolia
2. Effect of the extract of Rosa tenuifolia cells obtained from different combinations of culture media on skin cell proliferation
Keratinocytes are the most important cells in the epidermis and participate in the formation of the physical barrier of the skin, preventing invasion of adverse factors such as physical, chemical and microbial factors, and protecting the skin. One of the main characteristics of skin after aging is the thinning of the epidermis and the slow rate of wound healing, which is mainly caused by the reduced regenerative capacity of keratinocytes in the epidermis layer and the reduced proliferative capacity of the keratinocyte system. Human skin fibroblasts are the most important cells in the dermis reticulation layer of the skin, and are one of the main repair cells after skin aging and cell damage. It not only can promote migration, proliferation and differentiation of epidermal cells, but also can secrete a large amount of collagen, elastin and various cell repair factors, and has strong self-renewal capacity, so that aged skin can be repaired.
The prepared samples are prepared into a solution by deionized water, added into human immortalized epidermal HaCat cells or human primary Fibroblast (FB) culture solution, and the solvent without the samples is taken as a blank control. After 48 hours of culture, the cells were stained by MTT method, absorbance at 550nm was measured by an enzyme-labeled instrument, the proliferation rate of the blank control was 100%, and the effect on HaCat or FB cell proliferation was evaluated by reference to the blank control.
As is clear from the results shown in Table 8, the extract of fine rose cells obtained by culturing the following combination medium has a certain proliferation promoting effect on both skin cell epidermis HaCat cells and fibroblasts, and the promoting effect of examples 1 and 3 and examples 10, 15 and 17 is stronger than that of the medium A group, and the promoting effect of example 1 is the best.
TABLE 8 Effect of different combinations of Rosa tenuifolia cell extracts on skin cell proliferation
3. Protective effect of Rosa tenuifolia cell extracts obtained from different combinations of culture media on oxidative damage of skin cells
The free radicals can cause various irreversible oxidative damages to organisms at the cellular level, the molecular level and even the tissue organ level, accelerate the aging process of organism cells and even the whole organism, and induce various diseases related to aging. Hydrogen peroxide (hydrogen peroxide, H) 2 O 2 ) Is an important oxygen free radical in cells, and can cause direct oxidative stress reaction and oxidative damage caused by oxidative stress to human skin cells. In vitro utilization of H 2 O 2 Can induce and accelerate aging process of cells caused by oxidative stress, and simulate pathological process of oxidative damage in vivo.
Human immortalized epidermic HaCat cells or human primary Fibroblasts (FB) are planted in 96-well plates, cultured for 24 hours, and then added with drugs and H 2 O 2 (1 mM) culture medium for 24 hours, and MTT method was used to measure cell viability. By not adding H 2 O 2 Treated as a control group, the cell viability of the control was 100%, the control was referenced to the control, and H was evaluated 2 O 2 And the effect of sample processing on cell viability.
From the results shown in Table 9, the cell extracts of examples 1 to 4 have an obvious protective effect on the cell oxidative damage caused by hydrogen peroxide, and the cell extracts of examples have an obvious protective effect on the cell oxidative damage caused by hydrogen peroxide in the HaCaT cell model, and the protective effect is stronger than that of the culture medium A group. Among the two cell oxidative damage models, the protection effect of the combination of the four effective components is best. In combination with the DPPH clearance test result, the clearance rate of the control group is higher than that of the test group, and it is speculated that the extract of the rosa tenuifolia cells cultured by adding other functional components into the culture medium may have different antioxidant pathways compared with the culture medium A.
TABLE 9 protection of skin oxidative damage by different combinations of Rosa tenuifolia cell extracts
4. Ultraviolet injury protection effect of Rosa tenuifolia cell extracts obtained from different combination culture mediums
Aging of skin is classified into endogenous aging and exogenous aging, and sunlight, particularly Ultraviolet (UV) irradiation, is a major factor in the formation of exogenous aging, so exogenous aging is also called photoaging. Associated with skin photoaging are mainly UVA (320 nm-400 nm) and small amounts of UVB (280-320 nm). Many data indicate that 95% of the uv light that is irradiated to the skin is absorbed by keratinocytes, and that exposure of the skin to UVA radiation generates ROS and causes various damage, including oxidative stress. Ultraviolet UVB directly acts on epidermal cells, and the skin barrier function is further affected by the induction of oxidative stress and inflammatory processes, so that photodamage is formed. We therefore established a model of photodamage to skin by irradiation of dermal Fibroblast fibroblastist cells with UVA/UVB, and used this model to evaluate the protective effect of actives on skin uv damage.
Human immortalized epidermal HaCat cells or human primary Fibroblasts (FB), seeded in 96-well plates at 37 ℃ with 5% CO 2 Culturing in a cell culture box for 24 hours. Then adding the mixture into the whole culture medium containing the drug or solvent control for culturing for 24 hours. The medium was replaced with PBS and subjected to UVA/UVB irradiation at a dose of 10J/cm 2 Or 40J/cm 2 . After PBS was removed, the culture medium containing the sample to be tested was added and the culture was continued for 24 hours, and the MTT method was used to measure the cell viability. The non-UVA/UVB-irradiated group was used as a blank control group (UVA-/UVB-), and the UVA/UVB-irradiated group was used as a control group (UVA+/UVB+). Cell viability of the blank was100%, reference blank, assess the effect of UVA/UVB and sample treatment on cell viability.
As is clear from the results in Table 10-1, the cell extracts of Rosa tenuifolia obtained from the different combinations of the following media had less cell damage to UVA than the group A media, and had no significant protective effect on UVA.
TABLE 10-1 protection of skin UVA injury by Rosa tenuifolia cell extract

TABLE 10-2 protection of skin UVB lesions by different Rosa tenuifolia cells
5. Whitening effect of rose cell extracts obtained from different combination of culture media
Recent studies have demonstrated that pigmentation is caused by ultraviolet light activating melanogenesis enzymes in melanocytes in the epidermis, producing pigment. Melanocytes in basal lamina in the human epidermis are in contact with and associated with surrounding keratinocytes to form "epidermal melanocytes," where melanin is a nitrogen-containing complex synthesized in melanosomes. Generally, the amount and quality of melanin in the skin is an important factor in determining the skin color. In the melanin production process, tyrosinase converts tyrosine into dopa, and dopaquinone is polymerized into macromolecular melanin through non-enzymatic oxidation. Thus, by inhibiting tyrosinase activity, melanin production can be restricted and skin pigmentation can be improved.
The skin color is derived from melanin stored within keratinocytes. Generally, people with increased storage melanin are darker in their skin and are also more protected from solar radiation. The amount and quality of melanin is an important factor in determining skin color in skin melanin. Tyrosinase is a copper-containing oxidoreductase with a complex structure, and is widely used in microorganisms, animals, plants and human bodies. Tyrosinase is a key enzyme in the synthesis of melanin by the skin in humans.
The inhibition of tyrosinase by the samples was determined by L-Dopa oxidation. The melanoma B16 cells of the mice are planted in a 96-well plate, after 24 hours, the complete culture medium containing the drugs is added for culturing for 48 hours, the complete culture medium is washed by PBS for 2 times, 1 percent TritonX-100 (in PBS) is added, and the mixture is quickly placed in a refrigerator at-80 ℃ for 30 minutes. Thawing at room temperature or 37 ℃, lysing cells, and shaking and mixing uniformly. Adding 0.2% dopa water solution, shaking and mixing, reacting at 37 ℃ for 3 hours, and measuring OD490nm. The enzyme activity was calculated as follows: tyrosinase inhibition ratio = [1- (experimental group OD value/control group OD value ] ×100% ], a group without extract addition was used as a blank control.
From the results shown in Table 11, the extract of the cells of Rosa tenuifolia of example 1 and example 17 has an inhibitory effect on the tyrosinase activity of the B16 cells of melanoma in mice, and the inhibitory effect is stronger than that of the group A culture medium.

Taken together, the results show that, compared with the culture medium A, examples 1-4 are significantly improved in terms of resisting oxidative damage to both HaCaT skin cells and FB skin cells, while examples 5-19 are not improved in terms of resisting oxidative damage to both HaCaT and FB skin cells. The example 1 is superior to the culture medium A in promoting the proliferation of the fine-stalk rose cells, and the fine-stalk rose extract has the effects of promoting the proliferation of HaCaT and FB skin cells, resisting oxidation injury, inhibiting tyrosinase activity and the like, and has a slightly improved UVA resistance to the HaCaT cells.
