[0009] Describe GABA (gamma-aminobutyric acid):
[0010] GABA was discovered in mammalian brain extracts by the group of Roberts and Awapara in 1950 and identified as an inhibitory neurotransmitter in the elongation receptors of crustaceans. In addition to its nerve-calming effects, GABA is attracting attention as an excellent functional material possessing various physiological activities, such as inhibiting blood pressure elevation, anti-stress effects, promoting brain metabolism, improving liver function, and regulating growth hormones; it is currently widely used as a food additive both domestically and internationally. In particular, regarding its nerve-calming function, tablet-type products mixed with vitamins are predominant, and various forms of products ranging from cosmetics to pharmaceuticals are also being released and sold.
[0011]
[0012] Describe Myricetin:
[0013] Myricetin is a natural flavonol also known as 3,3',4',5,5',7-hexahydroxyflavone, cannabiscetin, myricetol, and myricitin. It is found in large quantities in the form of glycosides, mainly in tea, grapes, onions, broccoli, apples, and other foods. Pure myricetin is a yellow-beige crystalline powder.

[0037] Solution Principle: Enhancing GABA efficacy with myricetin
[0038] GABA receptors are receptors that respond to GABA, a neurotransmitter that is a major inhibitory compound in the central nervous system of mature vertebrates. There are two classes of GABA receptors: GABAa and GABAb. GABAa receptors are also called ligand-gated ion channels or ionotropic receptors. GABAb receptors are G protein-coupled receptors, also known as metabotropic receptors.
[0039] Myricetin does not act directly on GABA receptors, and Ca 2+ Involved in channels, intracellular Ca 2+ It increases ions to activate CaMK-II (calcium / calmodulin-dependent protein kinase II), and CaMK-II phosphorylates GABAa receptors, thereby exposing intracellular GABAa receptors to the surface. The exposed GABAa receptors diffuse close to the presynapse, Cl - As ions increase within the cell, the cell membrane potential is maintained at a low level, thereby stabilizing the nerve.
[0040] The solution principle of the present invention is to further enhance the efficacy of GABA with myricetin by providing a method for preparing a composition containing both GABA and myricetin and a composition made by said method.
[0041]
[0042] Preparation Example 1. Processing of Rock Rose Extract: Conversion to Myricetin
[0043] FIG. 1 relates to a method for converting myricitrin contained in a rock rose extract into myricetin by acid hydrolysis. Myricetin is prepared using rock rose (Cistus incanus). Myricetin is prepared by concentrating an extract obtained from the leaves and stems of rock rose and then performing acid hydrolysis. Hot water or ethanol is used as the extraction solvent. In a preferred example, a primary extract is prepared by chopping the leaves and stems of rock rose and then extracting them in 10 times their weight in distilled water at 50 to 80°C for 3 to 4 hours. Next, the primary extract is acid hydrolyzed to prepare a rock rose extract in which myricitrin is converted into myricetin.
[0044]
[0045] Preparation Example 2. Preparation of a composition for stress improvement comprising GABA and rock rose extracts as active ingredients
[0046] GABA is a type of non-protein amino acid found in nature and is an inhibitory neurotransmitter that improves cerebral blood flow, increases oxygen supply, and promotes brain cell metabolic function. It is known to have nerve-calming effects, help relieve stress, improve memory, and alleviate insomnia, as well as effects on lowering blood pressure, alleviating depression, and preventing stroke and dementia.
[0047] The GABA used in the present invention may be natural GABA or synthetic GABA, but is not limited thereto. GABA can be administered to animals at a concentration of 20 to 500 ppm per 100g of body weight to enhance erythropoietin expression, preferably at 50 to 200 ppm, but is not limited thereto.
[0048] Preparation Example 2 according to the present invention is to prepare a composition comprising GABA and the processed rock rose extract of Preparation Example 1. A preferred example is to provide a composition comprising GABA and rock rose extract in an amount of 1 / 10 to 1 / 5 relative to the GABA content.
[0049]
[0050] Experimental Example 1. Analysis of Erythropoietin Enhancement
[0051] (Patent Document 1) is a registered patent held by the applicant. The analysis of EPO increase in rat serum described in (Patent Document 1) was used. During the rearing period, experimental groups were established in which GABA was consumed at a rate of 100 ppm per 100 g of body weight via drinking water for 3 weeks (100 ppm, G100), GABA was consumed together with a rock rose extract at a ratio of 1 / 10 of the GABA content (110 ppm, G100+R10), and GABA was consumed together with a rock rose extract at a ratio of 1 / 5 of the GABA content (120 ppm, G100+R20). After correcting the NC and G100 values to the values of (Patent Document 1), the EPO increase in the presence of rock rose extract was confirmed.
