본 발명은 버섯 재배용 배지에 관한 것으로, 더욱 상세하게는 인체의 혈액을 활성화시키는 효과를 가지는 것으로 잘 알려진 징코플라본글리코사이드를 함유하는 은행잎을 이용한 배지 및 그 제조방법에 관한 것이다. The present invention relates to a culture medium for mushroom cultivation, and more particularly, to a medium using a ginkgo leaf containing the ginkgo flavone glycoside known to have an effect of activating the blood of the human body and a method for producing the same.

담자균류에 속하는 버섯(mushroom)은 각종 유기물을 분해하여 성장 발육하는 자실체를 가지고 있으며 중요한 식품자원이면서 동시에 약용식물로 알려져 왔다. 최근에는 생활수준이 향상되어 국민보건에 관심이 고조되면서 청정농산물의 재배와 기능성 식품에 점점 관심이 집중되고 있다.Mushrooms (mushroom) belonging to basidiomycete have fruiting bodies that grow and decompose and decompose various organic materials, and have been known as important food resources and medicinal plants at the same time. Recently, as the standard of living has improved and the interest in public health has been increasing, attention has been focused on the cultivation of clean agricultural products and functional foods.

버섯은 그 종류에 따라 맛과 향이 독특하며 단백질, 비타민 기타 무기영양소를 많이 함유하고 있으며 특히 섬유소가 다량 함유되어 있어 미용, 건강용 식품이 됨은 물론 변비와 항암효과가 보고되고 있다.Mushrooms are unique in taste and aroma, and contain a lot of protein, vitamins and other inorganic nutrients. Especially, mushrooms contain a large amount of fiber, making them a beauty and health food, as well as constipation and anti-cancer effects.

종래의 버섯재배용 배지를 보면 원목을 이용하는 방법, 볏집을 주재료로 한 제품, 볏집과 왕겨를 주재료로 한 제품, 볏집이나 톱밥을 주재료로한 제품 등이 개발된 바 있다.In the conventional mushroom cultivation medium, a method of using wood, a product mainly made of crests, a product mainly made of crests and chaff, and a product made of crests or sawdust as a main material have been developed.

원목의 경우에 있어서 참나무 등의 원목은 그 습득이 용이하지 않고 원가상승의 요인이 되어 왔다. 그뿐만 아니라 많은 재배면적이 필요하고 많은 인력이 소요될 뿐만 아니라 인력을 적기에 구하기가 곤란하였다. 또한 재배기간도 봄, 가을에 제한되고 5~6년 장기간 소요된다. 이러한 단점을 개선하기 위하여 각종 식물성 섬유물질을 분쇄하거나 절단하여서 되는 톱밥배지, 볏집배지 및 왕겨배지 등 인공배지가 개발된 바 있다.In the case of solid wood, solid wood such as oak is not easy to learn and has been a factor in the cost increase. Not only that, it requires a lot of cultivation area, a lot of manpower, and it is difficult to find manpower in a timely manner. The growing season is also limited in spring and autumn and takes a long period of 5-6 years. In order to improve these disadvantages, artificial media such as sawdust badges, crest badges and chaff badges, which have been pulverized or cut, have been developed.

그러나, 이러한 배지들은 버섯균사의 활성화에 적잖은 문제점이 있으며, 이를 인공배지의 혼합, 살균, 접종단계에 있어 상당한 노동력이 소요되고 있는 단점이 있다.However, these mediums have a considerable problem in the activation of mushroom hyphae, there is a disadvantage that takes a considerable labor in the mixing, sterilization, inoculation step of artificial medium.

Isolation and content analysis of each component of GFG, the main active ingredient of ginkgo biloba extract, and small amounts in ginkgo biloba extract, and separation and characteristics of ginkgolides and bilobalide, which have recently gained much attention. There is an active research on. In addition, Anacardic Acid, Bilobol, and Cardanol, Seven Long Chain Phenols compounds, which have recently been found to have an anticancer effect, were isolated by Tokyo Pharmaceutical University Itokawa et al. In 1986. Other specific compounds, such as Bilobetin, Ginkgetin, Isoginkgetin, and Siadopity, are detected. There is extensive chemical research on effective bioactive substances. The results of the pharmacological research are as follows.

은행잎을 의약품으로 처음 연구 개발한 곳은 독일 Dr .Schwabe社로 Peter 등 연구원들이 1966년 최초의 주성분인 징코플라보노이드(Ginkgoflavonoids)를 분리 발표하면서 그들이 말초 및 뇌혈관 순환장애에 치료효과가 있음을 발견하였다. 그 후 계속적인 약리작용 및 기전을 연구한 결과 말초혈관 확장 및 혈액순환 촉진, 혈관의 저항감소 및 콜레스테롤 감소, 혈관 항경련 작용 등 혈액 및 혈관에 대한 약리작용을 알아냈으며 최근 프랑스 연구소에서 뇌혈류량 증가, 뇌대사 촉진 등의 뇌기능 순환개선 작용을 나타내고 있음을 보고하였다. 그리고 최근 새로운 혈소판 응집촉진물질(Platelet-Activating Factor)이 발견되면서 은행잎과 은행나무 뿌리에 소량함유되어있는 징코라이드(Ginkgolides)의 혈소판 응집저해작용에 대한 연구가 전세계적으로 유명한 생화학자, 약리학자들에 의해 깊이 연구되고 있고 그 결과 현재 혈소판 응집저해, 수술 및 저혈압 등에 의한 쇼크 방지, 항알레르기(천식치료효과 등), 면역기는 증가, 프로스타글란딘(Prostaglandin) 생성저해 등 PAF-Antagonist는 향후 알레르기, 암, 류마치스 등의 인간이 정복하지 못한 불치질환이나 그 영역에 획기적인 예방약물로 기대되고 있어 은행나무에 함유하고 있는 징코라이드(Ginkgolides)는 앞으로 인류에게는 없어서는 안 될 약물이 될 것이다. The first research and development of ginkgo biloba as a medicine was Dr. Schwabe, Germany, and researchers, in 1966, released Ginkgoflavonoids, the first active ingredient, and found that they had therapeutic effects on peripheral and cerebrovascular disorders. . Subsequent studies of pharmacological action and mechanisms revealed pharmacological effects on blood and blood vessels, including peripheral blood vessel expansion and blood circulation, blood vessel resistance and cholesterol reduction, and vascular antispasmodic effects. It has been reported that the brain function is improved, such as the promotion of brain metabolism. And recently, with the discovery of a new platelet-activating factor, biochemists and pharmacologists around the world have studied the platelet aggregation inhibitory effects of Ginkgolides in small amounts in the ginkgo leaves and ginkgo roots. PAF-Antagonist is currently studying allergies, cancers, etc., including deep platelet aggregation, prevention of shock from surgery and hypotension, anti-allergic effects (asthma, etc.), increased immunity, and inhibition of prostaglandin production. Ginkgolides contained in Ginkgo biloba will be an indispensable drug for humanity as it is expected to be an incurable disease that has not been conquered by humans such as rheumatism or a groundbreaking preventive drug in the area.

또한 은행잎에서만 존재하는 빌로바라이드(Bilobalide) 화합물은 현재 독일에서 새로운 신경계 약물로서 깊이 연구하고 있는데 주로 뇌신경계, 척수신경계, 근신경계 및 신경전달물질(Neurotransmitter)에 대한 약효를 입증하여 향후 노인성치매, 노인성 천식, 심장질환 등과 같은 노인성 질환의 치료약물로써, 그리고 퇴행 성 뇌 및 척수신경계 질환의 치료제로써 개발하기 위한 노력이 집중적으로 진행되고 있다. 그밖에 은행나무에 특이하게 존재하는 유효생리활성물질에 대해서도 항암, 항바이러스(Anti-Viral), 저해제(Anti-Feedant) 등의 많은 약리학적 연구가 계속 진행되고 있어 머지않아 또 새로운 분야의 물질이 발견될 것을 의심치 않는다. 특히 징코플라본글리코사이드(Ginkgoflavonglycosides)를 주성분으로 함유하고 있는 은행잎 추출물에 대한 생체내 이용과정 및 약리학적 연구가 각국에서 많은 약리학자 ,생리학자들에 의해 1960년 말부터 깊이 진행되어 왔다. In addition, bilobalide compounds, which are present only in ginkgo biloba, are currently being studied in Germany as a new neurological drug. They mainly proved their effects on the brain, spinal nerve, musculature, and neurotransmitters. Efforts are being made to develop medicinal drugs for senile diseases such as senile asthma and heart disease, and to treat degenerative brain and spinal cord nervous system diseases. In addition, many pharmacological studies, such as anti-cancer, anti-viral, and anti-Feedant, continue to be conducted on effective physiologically active substances specific to ginkgo biloba. Do not doubt to be. In particular, the bioavailability and pharmacological studies of ginkgo biloba extract, which contains Ginkgoflavonglycosides as a main ingredient, have been conducted by many pharmacologists and physiologists in various countries since the late 1960s.

이하, 본 발명을 보다 상세하게 설명하기로 한다. Hereinafter, the present invention will be described in more detail.

본 발명에 따르는 버섯 재배용 배지는 건조중량기준으로 통상의 버섯배지성분 40~90중량%와 입자크기 0.1~0.5mm의 건조 은행잎박 10~40중량%를 함유한다. The mushroom cultivation medium according to the present invention contains 40 to 90% by weight of conventional mushroom medium components and 10 to 40% by weight of dried ginkgo leaf foil having a particle size of 0.1 to 0.5mm.

본 발명에 있어서, 은행잎박은 은행잎을 수분함량 10%이하가 되도록 건조한 후 입자크기가 0.1~0.5mm가 되도록 분쇄한 것이다. In the present invention, the ginkgo biloba foil is ground to dry the ginkgo leaf to less than 10% moisture content and then pulverized to a particle size of 0.1 ~ 0.5mm.

은행잎박은 통상 6월에서 10월초 사이에 채취되는 은행잎을 의약용 은행잎추출물을 얻기 위하여 분쇄하여 에탄올 등과 같은 추출용매에서 일부 GFG성분을 추출하고 남은 은행잎박에서 추출용매를 제거하고 건조한 것을 사용할 수도 있고, 추출가공되지 않은 은행잎을 분쇄, 건조한 것을 사용할 수도 있다. 은행잎에는 통상 3.45%의 GFG를 함유하고 있는 것으로 알려져 있으며, 상기 추출용매로 추출가공된 은행잎박에는 GFG함량이 1.70% 정도 잔류되어 있다. Ginkgo leaf gourd is usually pulverized to obtain a medicinal ginkgo leaf extract obtained from June to early October to extract some GFG components from an extraction solvent such as ethanol, remove the extraction solvent from the remaining ginkgo leaf gourd may be used dry, It is also possible to grind and dry ginkgo leaves that have not been extracted. Ginkgo biloba leaves are generally known to contain 3.45% of GFG. Ginkgo biloba leaves extracted and processed with the extracting solvent have a GFG content of about 1.70%.

본 발명의 배지중에 은행잎박의 함량은 배지 건조중량기준으로 10~40중량%, 보다 바람직하게 15~35중량%이다. 은행잎박의 함량이 10중량% 보다 적은 경우에는 버섯의 GFG성분의 흡수량이 적어 약리학적 기능을 갖는 고품질의 버섯을 재배하는 것이 어렵고, 또한 40중량% 보다 많은 경우에는 버섯이 흡수할 수 있는 GFG성분은 무한대로 흡수되지 않는 단점이 있어 경제성이 떨어지며, 또한 버섯 생육이 지연되고, 일부 사멸되는 현상이 발생할 수도 있다. 또한 은행잎박의 크기는 0.1~0.5mm가 적당한데, 그 이유는 은행잎박의 크기가 상기한 범위에서 벗어나면 배지제조시 혼합이 어렵고, 수분공급이 불균일하여 균사배양이 불균일하고, 양호한 수량으로 버섯을 재배하는 것이 어렵게 된다. The content of ginkgo leaf foil in the medium of the present invention is 10 to 40% by weight, more preferably 15 to 35% by weight based on the dry weight of the medium. If the content of ginkgo biloba is less than 10% by weight, it is difficult to cultivate high-quality mushrooms with pharmacological function due to the low absorption of GFG components of the mushrooms. Has the disadvantage that it is not absorbed indefinitely, it is less economical, and may also delay the growth of mushrooms, and may cause some death.

The mushroom's color is near white when no ginkgo leaves are added, but when the 30% of ginkgo leaves are added, it becomes white and glossy. In addition, after harvesting for 3 hours after exposure to the outside of the ginkgo biloba produced in the ginkgo leaf-free medium, the top of the mushroom was wrinkled, strained, but when the addition of 30% ginkgo biloba leaves the mushroom was kept round. In the growth process, the medium added with 30% of ginkgo leaf gourd did not generate any aerial mycelium at all compared to the ginkgo leaf free medium, thereby improving work efficiency. In the fungi tasting, the top mushrooms produced on the ginkgo leaf free medium had a mildew smell and chewy taste, but the top mushrooms produced on a medium containing 30% ginkgo leaf foil had no smell, and had a chewy, sugary, savory taste. there was.
