Abstract

 The present invention relates to a yunpanmul extract exhibiting anti-inflammatory activity. More specifically, the present invention relates to an anti-inflammatory composition containing the extract of Yunpanmul as an active ingredient by extracting the ground part of the Yunpanmul, the lily family, with methanol as a solvent. In addition, it was confirmed that the expression of iNOS (inducible Nitric Oxide Synthase), a gene that regulates the generation of nitric oxide, was also reduced. Therefore, Yunpan sprout extract has an effect that can be provided as an anti-inflammatory composition, processed foods, functional foods, or food additives that can suppress inflammation caused by inflammation-inducing substances.

Description

Anti-inflammatory effect of extracts of Disporum sessile D.Don}

The present invention relates to a yunpanmul extract exhibiting anti-inflammatory activity. More specifically, the present invention relates to an anti-inflammatory composition containing the extract of Yunpannamul as an active ingredient by extracting the ground part of Yunpannaum, which is a lily plant, as a solvent, and an anti-inflammatory composition capable of suppressing inflammation caused by an inflammation-inducing substance. To provide a processed food, functional food, or food additives.

The present invention relates to a yunpanmul extract having an anti-inflammatory effect, in particular, to provide a food composition for health promotion using the yunpanmul extract.

 An inflammatory response is a mechanism for repairing and repairing an injured area when an invasion that causes any organic change in the body or tissue, such as physical action, chemicals, or bacterial infection, is applied.

 In other words, macrophages act when living organisms become infected with pathogens or when the immune system is hyperactive for some reason. Macrophages play an important role in defending the host against pathogens with the help of active agents of T-cells, which are pathogens and immune cells, and this activity is regulated by several mediators. In particular, the production of nitric oxide (NO) by nitric oxide synthase (NOS) of macrophages acts as an important mediator of killing or inhibiting growth of bacteria, fungi and parasites. .

Recent studies show that NO is a free radical produced from arginine by three major NOS isoforms: neuronal NOS (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS). nNOS and eNOS are controlled by Ca 2 + / calmodulin (calmodulin), but, iNOS is regulated at the transcriptional level by inflammatory stimuli such as IL (interleukin), IFN (interferon), LPS. NO produced in a few seconds by nNOS or eNOS is responsible for normal physiological functions such as vasodilation, neurotransmission, and cellular destruction of pathogens, but overproduction of iNOS in macrophages reacts with superoxide. It forms peroxynitrite, which acts as a powerful oxidant, causing damage to cells and activating NFκB in macrophages activated by inflammatory stimuli, which are involved in chronic diseases such as inflammatory reactions, cancer, and atherosclerosis. Known. Korhonen. Et al., Current Drugs target ., 4 , pp 471-479, 2005; TJ GUZIK Et al., JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY ., 4, pp 469-487, 2003)

NO is known to be produced by iNOS in various pathophysiological processes, including inflammation and cancer. NOS is an important enzyme that regulates inflammation, vasodilation, neurotransmission, tumor cell and body homeostasis, and produces NO from L-arginine. In inflammatory conditions, macrophages produce large amounts of NO by iNOS. It is known to cause various chronic diseases. Expression of iNOS is induced by NFκB activity, which is an important mechanism by which LPS or cytokine is overproduced in macrophages.

Until now, there is no substance or product mainly composed of yunpanmul. In addition, since there are not many data showing anti-inflammatory activity among the efficacy of general health foods based on scientific basic data, it can be safely consumed using natural extracts, can suppress inflammatory reactions, and can be easily used in foods. There is a need for research on materials.

SUMMARY OF THE INVENTION The present invention is for the popular dissemination of yunpanmul, useful for preventing inflammatory diseases, and has an object of providing a processed beverage while exhibiting the pharmacological activity of the yunpanmul.

In addition, an object of the present invention is to provide a beverage composition, a food additive, etc. to which the Yunpannamul extract excellent in anti-inflammatory activity of the present invention is added.

Yunpanmul extract is washed with running water to remove foreign matter by washing with Yunpanmul (Disporum sessile D.Don), dried in sunny place, pulverized to powder, and deposited in 80% methanol, and the methanol deposit is ultrasonically After extracting three times for 30 minutes, the supernatant of the extract was recovered, concentrated under reduced pressure, the concentrate was suspended in water, the suspension was freeze-dried, and extracted with DMSO to prepare a yunpanmul extract. The NO production inhibitory activity and iNOS mRNA expression inhibitory effect of the Yunpannamul extract is confirmed to provide an extract that can be used as a food additive and a beverage composition of the Yunpannamul extract.

 The present invention is a material having excellent effects such as acute inflammation suppression by the inflammatory response, the degree of expression of the inflammation-inducing substance and the amount of phosphorylated NFκB protein expression, and can produce a health functional food having an inflammatory disease alleviating activity by controlling the inflammatory response. have.

 Also, because it is a plant, it can be used as a food additive and consumed. Accordingly, the present invention may exhibit an anti-inflammatory effect in addition to food, and may be used for inflammatory disease relief as a prophylactic agent.

Ingested by the method of the present invention, when ingesting a beverage composition for improving health comprising the Yunpannamul extract, will greatly help to improve the body's defense against cancer, bacteria, inflammation, diabetes and the like.
