Description

Technical Field

[0001] The present invention relates to a composition for improving blood flow and a composition having a cold symptom improving effect. Background Art

[0002] Cold syndrome is one of the self-reported symptoms caused by autonomic nervous system disorders, etc. It is a symptom confirmed in a wide range of generations from young to old, and is particularly common in women, with one in every two women said to suffer from cold syndrome.

[0003] It is believed that one of the main causes of cold syndrome is that stress and irregular lifestyle lead to decreased function of the autonomic nervous system, constriction of peripheral blood vessels, and decreased blood flow. In addition to organic symptoms such as headaches and back pain, cold syndrome may also cause systemic symptoms such as fatigue and decreased immunity.

[0004] Various studies have been conducted on ingredients that have the effect of improving cold symptoms. For example, cinnamon extract (Patent Document 1), black ginger rhizome extract (Patent Document 2), Indian gooseberry fruit (Patent Document 3), and piperine spike extract (Patent Document 4) have been reported to be effective in promoting peripheral blood flow and improving cold symptoms.

[0005] However, there is still a need for an ingredient that has a sufficient effect on improving cold symptoms.

[0034] The present invention will be described in more detail below with reference to Examples and Test Examples, but the present invention is not limited to these Examples and the like.

[0035] Example

[0036] Test Example 1

[0037] Adenosine A 2A Receptor agonist activity test:

[0038] The reporter cells were cultured in DMEM supplemented with 10% FCS and penicillin / streptomycin. The cells were freed using trypsin-EDTA and suspended in DMEM containing 10% dialyzed FCS. The suspended cells were seeded in a 96-well white microplate at 24,000 cells per well. The cells were cultured at 37°C for 1 night in the presence of 5% CO2 to allow the seeded cells to adhere to the bottom of the microplate.

[0039] Plasmids expressing GPCR, Gα protein, and luciferase reporter gene were mixed, and a total of 100 ng was transfected per well using a transfection reagent (FuGENE6, Promega), and cultured at 37°C overnight in the presence of 2.5% CO2.

[0040] 2 ml of DMSO was added to 180 mg of each of the powder of jujube seeds, perilla leaves, and mixed powder of jujube seeds and perilla leaves, and the solution was homogenized by ultrasonic treatment. After centrifugation (10,000 rpm, 10 minutes), the supernatant was recovered and filtered (0.45 μm) to prepare a crude drug extract.

[0041] The crude drug extract was diluted to 7 times the final test concentration using DMEM containing 10% dialyzed FCS, added to each well, and cultured at 37°C for 6 hours in the presence of 2.5% CO2. After aspirating the culture medium, a luciferase quantitative reagent (Steady-Glo, Promega) was added to the wells, and the luminescence of luciferase was measured using a microplate reader (Victor Nivo, Perkin Elmer).

[0042] Data analysis The Hill equation was approximated by nonlinear least squares method. The parameters were set as EC50, Hill coefficient, curve bottom, and curve top. The results are shown in Table 1. Figures 1 to 3 .

[0043] [Number 1]

[0044]

[0045] [Table 1]

[0046] Hill coefficient EC50(μg / mL) EC80(μg / mL) Chinese date seed 1.3 130 392 Perilla leaves 1.4 126 341 Ziziphus jujuba seeds + Perilla leaves 2.4 106 191

[0047] From these results, it was confirmed that the combination of wild jujube seeds and perilla leaves increased the Hill coefficient, which is a reactivity index, by about 80% compared with the use of each alone, showing a synergistic effect.

[0048] Example 1

[0049] Preparation of tablets containing spiny jujube seeds and perilla leaves

[0050] Add 10 times the amount of purified water to the cut raw materials of Chinese jujube seeds and Chinese perilla leaves, heat to 95-100°C under stirring, and extract for about 60 minutes. After the extraction, separate the extract into solid and liquid, concentrate the separated liquid under reduced pressure, and then spray dry to obtain dry Chinese jujube seeds and perilla leaves extract powder.

[0051] The obtained Ziziphus jujuba seed and Perilla leaf extract powders are mixed with lactose, microcrystalline cellulose and magnesium stearate, and tableted using a tablet press to produce tablets containing 1.85 g of Ziziphus jujuba seed and 0.18 g of Perilla leaf in terms of crude drug weight per 3 tablets (containing 52 mg in total as Ziziphus jujuba seed extract powder and Perilla leaf extract powder).

[0052] Test Example 2

[0053] Human trials

[0054] Thirty healthy women aged 35 to 50 were selected as subjects in each group. The tablets prepared in Example 1 were taken once a day for 12 weeks, and VAS (Visual Analogue Scale) was used to evaluate "coldness of fingers" and "coldness of toes" 4, 8, and 12 weeks after the start of intake (herbal medicine group). As a control, tablets without the extract powder of Ziziphus jujuba and Perilla leaf were taken and evaluated in the same way using VAS (control group). The results are shown in Figure 4 and Figure 5 .

[0055] As shown in this result, it was confirmed that the coldness of the extremities such as the hands, feet, and toes can be significantly improved by taking the wild jujube seeds and the perilla leaves together, and the effect is enhanced over time.

[0056] Industrial Applicability

[0057] By taking the composition of the present invention, peripheral blood flow is promoted and the effect of improving cold symptoms can be obtained, and it is useful as a medicine, food, etc. for improving cold symptoms.
