The present invention relates to a method for producing an Acanthopanax koreanum Nakai) stem extract, a fraction thereof, or a compound isolated therefrom as an active ingredient, to a cosmetic composition, a food composition and a pharmaceutical composition for antioxidant, anti-inflammation or antimicrobial use.

Oxygen is essential for many metabolic reactions for life support and it is necessary for the detoxification of toxic substances in the human body. However, not only oxygen is beneficial to human body, but also oxygen, reducing metabolism, chemical, , Environmental factors, etc., it is converted into a highly reactive free radical such as superoxide radical, hydroxyl radical, hydrogen peroxide, singlet oxygen There is a bi-aspect that causes lethal oxygen toxicity in living organisms ( Korea J. Biotechnol . Bioeng . , 2001, 16 (6), 592-602). BHT (butylated hydroxy toluene) and BHA (butylated hydroxy anisole), which are synthetic antioxidants for the removal of active oxygen, have been widely used because of their excellent antioxidative and economic properties. However, hepatic hypertrophy, And the amount of food and the amount of food to be used are strictly restricted. In addition, natural antioxidants such as tocopherol and ascorbic acid are high in safety, but they are disadvantageous in that they are low in chain reaction inhibiting ability and expensive. For this reason, researches for isolating and utilizing more safe, economical and effective antioxidants from natural products have been actively conducted recently. In particular, plant-derived secondary metabolites inhibit the production of free radicals and active oxygen since removing to prevent oxidation, many studies have been made about this (Korean Journal of Plant Res. , 2011, 24 (1), 30-39; J. Korean Soc . Food Sci . Nutr . , 2010, 39 (9), 1249-1256).

The color of skin is determined by three kinds of melanin, hemoglobin and carotene. Melanin is the most important role. Melanocytes are leaf-shaped dendritic cells that produce dark brown melanin in the basal layer of the epidermis. The main role of melanin is to remove active oxygen and free radicals from the skin and to protect the inside of the skin by blocking the penetration of ultraviolet rays. The starting material for making melanin is tyrosine, a kind of amino acid normally present in the human body. Tyrosine is oxidized by tyrosinase in melanocytes to become dopa (DOPA), and dopa is further oxidized into dopaquinone (DOPA quinone). Dopaquinone then undergoes autoxidation and ultimately produces dark brown eumelanin. On the other hand, when dopaquinone encounters cysteine, cysteinyl DOPA is formed, resulting in reddish brown pheomelanin. The resulting melanin is then transferred to the keratinocyte on the melanosome. However, when melanin is overproduced, pigmentation such as spots, freckles, dots, and black spots occurs, leading to skin aging and damage, and it is also known to be involved in the induction of skin cancer ( J. Korean Ind . Eng . Chem . 2005, 16 (3), 348-353). Studies on the recent whitening effects are proceeding with a comprehensive concept including skin whitening effect, antioxidant action, and prevention of skin aging. Currently known whitening studies include studies on UV blocking materials, studies to control the action of the cytokine, a signaling substance that commands the synthesis of melanin in melanocytes, suppression of gene expression, inhibition of tyrosinase action , Active oxygen scavenging material, pigment reduction, research to promote stratum corneum removal, and so on. Of these, the mechanism by which the activity of tyrosinase is inhibited and the initial production of melanin is reduced is the most studied.

Inflammation is a vital reaction caused by wound, infection, or autoimmune mechanism. When inflammation occurs, immune cells penetrate into the inflammation site and these cells are exposed to various kinds of

Chemical secretion, and cytokine production to produce bio-defense and inflammatory responses ( J. Korean Soc . Food Sci . Nutr . , 2010, 39 (7), 980-985). Lipopolysaccharide (LPS), also known as endotoxin, is present in the extracellular membrane of Gram-negative bacteria, and is expressed in macrophages or monocytes, such as RAW 264.7, by proinflammatory factors such as TNF-α, IL-6, It is known to increase pro-inflammatory cytokines. In addition, the formation of such inflammatory mediators leads to the process of converting arachidonic acid into prostaglandin and the formation of nitric oxide (NO) due to the activity of phospholipase A ₂ (phospholipase A ₂ ) . In vivo inflammatory process is formed by the excessive amount of NO and PGE ₂ (prostaglandin E ₂₎ inflammatory markers are iNOS (inducible NO synthase) and such as COX-2 (cyclooxygenase-2) . Although normal NO formation plays an important role in killing bacteria or eliminating tumors, NO produced by iNOS in the inflammatory state not only promotes inflammatory responses such as vascular permeability and swelling but also stimulates inflammation mediator biosynthesis, ( Korean Soc . Of Food Sci . Techn . , 2007, 39 (4), 464-469). There are numerous causes of inflammation, but one of them is biological causes such as bacteria, fungi, and viruses. Skin involved in causing the overburden skin inflammation of the bacterium Staphylococcus epidermidis (Staphylococcus epidermidis), PROFIBUS sludge tumefaciens arc Ness (Propionibacterium acnes), Stephen Pyrococcus Ou Russ (Staphylococcus aureus) and Rouge Labor (Pseudomonas Pseudomonas aeruginosa , and the like. Bacteria such as S. epidermidis , P. acnes , S. aureus , and P. aeruginosa are causative agents of purulent diseases such as boils, acne and otitis media in the skin. Because these fungi play a major role in inducing inflammatory responses, various antibiotics have been used to treat inflammatory skin diseases. Among the currently used antibiotics are erythromycin, tetracycline, clindamycin, macrolide, azelaic acid, retinoid, benzoyl peroxide and the like, , Benzoyl peroxide causes skin dryness and hypersensitivity, and erythromycin, tetracycline, clindamycin, and macrolide are resistant to antibiotics and are difficult to continue to use, have severe toxicity, and may have opportunistic infections such as candidiasis . Therefore, in order to solve these problems, we are trying to develop a therapeutic agent for skin irritation which has antimicrobial effect and no side effects using safe natural materials. In the recent inflammatory field research, it is necessary to find a natural antiinflammatory substance Is due to the high incidence of adverse side effects of conventional anti-inflammatory agents such as cortisol synthetic agents ( Korean J. Medicinal Crop Sci. , 2010, 18 (2), 105-112).

Under these circumstances, the present inventors have made intensive studies to find natural products having antioxidative, anti-inflammatory, or antimicrobial effects and less side effects, and as a result, (1, 1-diphenyl-2-picryl-hydrazyl) free radical scavenging effect of ethyl acetate fraction of Acanthopanax koreanum Nakai, ) Production inhibitory effect, an inflammatory cytokine production inhibitory effect and an inhibitory effect on the growth of the skin uptake bacteria as well as an excellent melanogenesis and intracellular tyrosinase inhibitory activity, .

The term "antioxidant" of the present invention means an antioxidant action. The human body has a balance between prooxidant and antioxidant, but due to various factors, And leaning towards oxidative stimulation leads to oxidative stress leading to potential cellular damage and pathological disease. Reactive oxygen species (ROS), which is a direct cause of oxidative stress, is unstable and highly reactive. It reacts easily with various bio-materials, attacks irreversible damage to cells and tissues, Cytotoxicity and carcinogenesis. The reactive nitrogen species (RNS) such as NO, HNO2, and ONOO- are produced in large quantities by the immune response of macrophage neutrophils and other immune cells during the inflammatory reaction.
