본 발명은 산초나무 추출물을 포함하는 흰가루병 방제용 천연 항균조성물에 관한 것으로, 보다 상세하게는, 인체에 무해하면서도, 흰가루병 곰팡이의 포자 발아 억제 및 균사 생육 억제를 통해 토마토, 오이, 딸기 등의 시설재배작물에 발생하는 흰가루병을 예방 및 제어하는 산초나무 추출물을 유효성분으로 포함하는 흰가루병 방제용 천연 항균조성물을 제공한다. The present invention relates to a natural antimicrobial composition for controlling powdery mildew, comprising an extract of the Japanese vinegar, and more specifically, harmless to the human body, while cultivating facilities such as tomatoes, cucumbers, strawberries through suppression of spore germination and mycelial growth of powdery mildew fungus It provides a natural antimicrobial composition for powdery mildew control comprising as an active ingredient extracts of the Japanese vinegar to prevent and control powdery mildew occurring in crops.

흰가루병은 토마토, 딸기, 오이, 참외, 호박, 수박, 장미, 작약 등 300 여종의 기주식물에서 발병되며, 스패로세카속(Sphaerotheca), 레베일루나속(Leveilluna), 에리쉬페속(Eryshipe), 푸사리움속(Fusarium)의 곰팡이가 원인균이며(대한민국 특허 공개번호 제10-2004-0066951호, 농업생명공학연구원 http://kacc.rda.go.kr), 시설 내에서 재배되는 여러 작물에서 광범위한 피해를 주고 있다. 흰가루병은 작물에 따라 증상이 다소 차이가 나지만 대부분 줄기, 잎, 열매에 흰가루 모양의 곰팡이가 피며, 병이 진전됨에 따라 식물의 광합성과 호흡을 저해하여 동화작용과 증산작용을 감소시켜 병반조직의 괴사와 함께 급속히 노화되 어 잎이 떨어지게 된다(이상엽 등, 2004, 한국농약과학회지 8, 71-78 ; 이옥희 등, 2001, 원예과학기술지 19, 7-11). 또한 흰가루병 곰팡이는 흰가루병 이외에 뿌리썩음병(근부병)에도 관여하는 것으로 알려져 있다(이순구 등, 2004, 식물병연구 10, 248-259). Powdery mildew is caused by over 300 species of host plants, including tomatoes, strawberries, cucumbers, melons, pumpkins, watermelons, roses, and peonies. Sphaerotheca , Leveilluna , Eryshipe , and Pusa Fusarium fungus is the causative bacterium (Korean Patent Publication No. 10-2004-0066951, Institute of Agricultural Biotechnology http://kacc.rda.go.kr), and extensive damage from various crops grown in the facility Is giving. Although powdery mildew has a slightly different symptom depending on the crop, most of them have white powdery molds on stems, leaves, and fruits. As the disease progresses, necrosis of lesion tissue is reduced by inhibiting photosynthesis and respiration of plants. Aging leaves rapidly fall and leaves fall (Lee Sang-yeop et al., 2004, Korean Journal of Pesticide Science 8, 71-78; Lee Ok-hee et al., 2001, Korean Horticultural Science and Technology Journal 19, 7-11). In addition to powdery mildew, powdery mildew is known to be involved in root rot (root disease) (Lee Soon-gu et al., 2004, Plant Disease Research 10, 248-259).

현재까지 이러한 흰가루병 곰팡이의 방제는 주로 디페노코나졸(Difenoconazole), 베노밀(benomyl) 및 만코젭(mancozeb) 등의 화학농약에 의존하여 왔으며(이상엽 등, 2004, 한국농약과학회지 8, 71-78), 이러한 화학농약의 연용은 결국 흰가루병 곰팡이의 약제저항성을 유발시켜 농약 효율성을 떨어뜨리게 되며, 화학농약을 기피하는 소비자들에게는 높은 잔류농약 검출로 인해 농약 사용 과채류가 배척되고 있는 실정이다. 이러한 문제를 해결하기 위해, 최근에는 내성 식물체 개발(이옥희 등, 2001, 원예과학기술지 19, 7-11), 길항 미생물 제제의 개발(이상엽 등, 2004, 한국농약과학회지 8, 71-78), 계면활성제 처리(대한민국 특허 공개번호 2001-0078568; 장경수 등 2001, 한국농약과학회지 5, 51-57), 및 탄산수소나트륨과 폴리옥시에틸렌 솔비탄모노라우레이트(polyoxyethylene sorbitanmonolaurate) 혼용처리에 의한 흰가루병 방제(남명현 등 2003, 원예과학기술지, 21. 98-101) 등 다양한 생화학적 방제법으로 화학농약을 보완, 대치하고자 많은 연구가 이루어지고 있다. To date, the control of powdery mildew fungi has largely relied on chemical pesticides such as Difenoconazole, benomyl and mancozeb (Lee Sang-yeop et al., 2004, Korean Pesticide Science Journal 8, 71-78). In addition, the use of such chemical pesticides induces drug resistance of powdery mildew fungi, which reduces the efficiency of pesticides, and the use of pesticides and vegetables is excluded due to the detection of high residual pesticides. In order to solve this problem, recently developed resistant plants (Lee Ok-hee et al., 2001, Horticultural Science and Technology Journal, 19, 7-11), development of antagonistic microbial agents (Lee Sang-yeop et al., 2004, Korean Journal of Pesticide Science 8, 71-78) Powder treatment by surfactant treatment (Korean Patent Publication No. 2001-0078568; Jang Kyung-Soo et al. 2001, Korean Journal of Agrochemical Sciences 5, 51-57), and a mixture of sodium bicarbonate and polyoxyethylene sorbitanmonolaurate Many studies have been conducted to supplement and replace chemical pesticides with various biochemical control methods such as control (2003, Nam Myung Hyun et al., Horticultural Science and Technology Journal, 21. 98-101).

한편, 화학농약에 비해 상대적으로 안전성이 높은 천연 추출물에 의한 흰가루병 방제 연구도 시도되고 있으며, 최근 식물체(율피, 감, 솔잎, 호프, 감비르나무, 해아다, 암마륵, 커피, 가자, 소목, 지유, 호장, 대황, 조 등)의 탄닌계 추출물을 포함하는 흰가루병 방제용 조성물이 보고되었으며(대한민국 특허 공개번호 제10-2004-0066951호), 생약재인 오배자(Rhus chinensis) 추출물에 의한 흰가루병 방제제(대한민국 특허공개번호 제10-2004-0056061호), 소리쟁이(Rumex crispus) 및 참소리쟁이(Rumex japonicus) 추출물을 함유한 흰가루병 방제 조성물(대한민국 특허공개번호 제2003-0068255호), 소목(Caesalpinia sappan), 황금(Scutellaria baicalensis), 정향(Syringa velutina var kamibayashii), 도두 (Canavalia glaviata), 엿기름을 함유하는 흰가루병 방제 조성물(대한민국 특허공개번호 제10-2004-0066955호)이 각각 알려져 있다. 그러나 많은 종류의 식물추출물을 혼합하여 동시에 사용하는 경우, 제조 및 사용의 어려움이 있으며, 경제적 생산이 용이하지 않으며, 특히 오배자 및 소리쟁이의 경우 원재료 획득 용이성과 잠재적 인체 독성의 문제를 가지고 있다(식품의약품안전청 식품원재료데이터베이스). On the other hand, research on powdery mildew control by natural extracts, which are relatively safer than chemical pesticides, has been attempted. Recently, plants (Julpi, persimmon, pine needles, hops, persimmon tree, Haida, amaranth, coffee, let's go, joiner, Jiyugaoka, polygonaceous, rhubarb, has been reported for powdery mildew control composition comprising a tannin-based extract of the tank, and so on) (Republic of Korea Patent Publication No. 10-2004-0066951 call), a gallnut saengyakjae (Rhus chinensis ) powdery mildew control agent (Korea Patent Publication No. 10-2004-0056061), Rumex powdery mildew control composition ( crispus ) and Rumex japonicus extract (Korean Patent Publication No. 2003-0068255), Caesalpinia sappan ), golden ( Scutellaria baicalensis ), cloves ( Syringa velutina var kamibayashii ), canavalia glaviata , and powdery mildew control composition containing malt (Korean Patent Publication No. 10-2004-0066955) are known, respectively. However, when many kinds of plant extracts are mixed and used simultaneously, they are difficult to manufacture and use, and economical production is not easy, and particularly in the case of gall bladder and raspberry, there are problems of easy raw material acquisition and potential human toxicity.

산초(Zanthoxylum schinifolium)는 동북아시아권에서 옛날부터 사용되어 온 전통 향신료이며 우리나라, 일본, 중국 등에서 널리 자생하고 있는 운향과(Rutaceae)의 낙엽관목으로서 분지나무 또는 상초나무로도 불린다. 높이는 3미터이고, 잔가지는 가시가 있으며 붉은빛이 도는 갈색이다. 잎은 어긋나고 꽃은 암수 딴그루이고 8∼9월에 흰색으로 피며 가지 끝에 산방꽃차례를 이루며 달린다. 작은 꽃자루에 마디가 있고, 꽃받침은 5개로 갈라지며 갈라진 조각은 달걀 모양의 원형이다. 열매는 삭과이고 둥글며 녹색을 띤 갈색이며 다 익으면 3개로 갈라져서 검은 색의 종자가 나온다. 초피나무와 비슷하지만 잎자루 밑 부분에 가시가 1개 달리고 열매가 녹색을 띤 갈색이며 꽃잎이 있는 것이 다르다. Sancho ( Zanthoxylum schinifolium ) is a traditional spice that has been used in Northeast Asia for a long time. It is a deciduous shrub of Rutaceae , which grows widely in Korea, Japan, China, etc., and is also called branch tree or vinegar. It is 3 meters high, and twigs are spiny and reddish brown. The leaves are alternate, the flowers are male and female, and bloom in white in August-September. A small peduncle has a node, the calyx is divided into 5 pieces, and the fragment is an egg-shaped circle. Fruits are capsules, round, greenish brown, and when they are ripe, they are divided into three and produce black seeds. It is similar to the bark tree, but has one thorn at the bottom of petiole, the fruit is greenish brown and has different petals.

산초는 과실, 껍질, 잎 등을 향신료, 약용 및 제유용으로 이용하며, 우리 정서에 친숙한 식미와 향기를 가져 광범위하게 사용되고 있으며, 구충제, 해독살충 약, 감기약 등에 이용되어 왔다(이종원, 1998, 한국식품영양과학회지, 11, 493-498). 산초의 보고된 성분으로는 리모네네(limonene), 시트로렐랄(citronellal)의 향기 주요성분과, 플라보노이드(flavonoid)계 성분, 카프릭산(caproic acid)등의 지방산 화합물이 있으며(조민구 등, 2003, 한약작지, 11, 40-45; 김정 등, 2000, 농산물저장유통학회지. 7, 189-194), 생리활성으로는 식중독 세균 및 피부사상균에 대한 항균 활성(김정순 등, 2004. 한국식품영양과학회지 33. 500-504; 민경희 1998, 목재공학 26; 78-85; 공개특허 10-2004-0075263)이 보고되어 있다. 그러나 현재까지 산초 추출물에 대한 흰가루병과 같은 식물 곰팡이 병원균 방제효과는 보고된 바 없다. Sancho uses fruits, bark, and leaves for spices, medicinal and oil-reducing oils, and is widely used because of its familiar taste and fragrance. It has been used for insect repellents, detoxification drugs, and cold medicines (Lee Jong-won, 1998, Korea) Journal of Food and Nutrition Science, 11, 493-498. The reported components of Sancho include fatty acid compounds such as flavonene, citronellal, main components of flavonoids, flavonoids, and capric acid (Cho Min-gu et al., 2003). , Korean Journal of Medicinal Crop, 11, 40-45; Kim, Jung et al., 2000, Journal of Agricultural Products Storage and Distribution. 7, 189-194), Physiological Activities of Antimicrobial Activity against Food Poisoning Bacteria and Dermatophytes (Kim, Jung-Soon et al., 2004. Journal 33. 500-504; Min Kyung-hee 1998, Wood Engineering 26; 78-85; Pub. 10-2004-0075263). However, there have been no reports on the control of plant fungal pathogens such as powdery mildew against the extracts of Sancho.

실시예Example 3: 산초추출물의 조제 및 유기용매에 의한 활성물질 분획 3: Preparation of Acid Extract and Fractionation of Active Substance by Organic Solvent

안동 재래시장에서 구입한 뿌리부분을 제외한 산초나무 음건물(열매껍질, 잎, 가지, 줄기)을 파쇄하고, 각 파쇄물에 1: 10 중량비율로 메탄올, 주정, 에틸아세테이트, 핵산을 각각 가하여 상온에서 24시간 활성물질의 추출을 시도하였다. 물 추출의 경우에는 18시간 동안 상온에서 추출하였으며, 열수추출의 경우에는 100℃에서 4시간 동안 추출하였다. 추출액은 여과지(와트만 여과지 No.2)로 여과 후 감압농축하여 분말화하였다. 감압농축 시 온도는 60 내지 80℃를 유지하며 냉각관을 부착한 감압농축기를 사용하며 시간은 추출용매에 따라 적절히 조절할 수 있다. 조제된 추출물을 실시예 2에서 기술한 디스크법으로 흰가루병 곰팡이의 성장 억제 효과를 측정하였으며, 표 2에는 각각의 추출용매별 추출효율과 종이디스크당 50 ㎍의 추출물을 떨어뜨린 경우 메탄올추출물에서 억제 활성이 나타남을 표시하였다. 따라서 흰가루병 방제용 산초추출물의 조제는 추출효율이 우수하며, 방제효과도 우수한 메탄올추출물이 바람직하다. Crush the vinegar dry matters (berry bark, leaves, branches, stems) except the roots purchased from Andong traditional market, and add methanol, spirit, ethyl acetate and nucleic acid to each crushed substance at a ratio of 1:10 by weight. Attempted extraction of the active material for 24 hours. In the case of water extraction was extracted at room temperature for 18 hours, in the case of hot water extraction was extracted for 4 hours at 100 ℃. The extract was filtered through filter paper (Watman filter paper No. 2), concentrated under reduced pressure, and powdered. Temperature under reduced pressure concentration is maintained at 60 to 80 ℃ using a reduced pressure condenser with a cooling tube, the time can be appropriately adjusted according to the extraction solvent. The prepared extracts were measured for the growth inhibitory effect of powdery mildew fungus by the disk method described in Example 2. Table 2 shows the inhibitory activity in methanol extract when the extraction efficiency of each extractant and 50 ㎍ of extract per paper disk were dropped. It is indicated that this appears. Therefore, methanol extract having excellent extraction efficiency and excellent control effect for powdery mildew extract control is preferable.

메탄올추출물의 활성분획을 얻기 위해 통상의 분획 방법으로 메탄올추출물을 1: 10 중량비로 물에 현탁한 후, 현탁액: 핵산을 1: 5 부피비가 되도록 첨가하여 반복 분획하였다. 이후 핵산 분획을 회수하고, 에틸아세테이트, 부탄올을 각각 사용하여 순차적으로 분획한 후 최종적으로 물 분획을 회수하였다. 회수된 분획물은 상기 기술한 방법으로 감압농축하여 분말화하였고, 이를 DMSO 및 물에 녹여 디스크법으로 흰가루병 곰팡이 성장억제 효과를 측정하였다. In order to obtain an active fraction of the methanol extract, the methanol extract was suspended in water at a ratio of 1: 10 by weight in a conventional fractionation method, and then the fraction was repeatedly added by adding a suspension: nucleic acid at a ratio of 1: 5 by volume. Thereafter, the nucleic acid fractions were recovered, fractionated sequentially using ethyl acetate and butanol, respectively, and finally water fractions were recovered. The recovered fractions were concentrated under reduced pressure by the method described above to be powdered and dissolved in DMSO and water to measure the effect of powdery mildew growth inhibition by the disk method.

표 3에 나타난 바와 같이, 각각의 분획용매별 분획수율과 종이디스크당 50 ㎍의 추출물을 떨어뜨린 경우 물 분획에서 억제 활성이 나타났다. 따라서 흰가루병 방제를 위한 천연물로는 산초나무의 메탄올추출물 및 메탄올추출물의 물 분획물이 가장 바람직함을 확인하였다. As shown in Table 3, when the fraction yield of each fraction solvent and 50 ㎍ of extract per paper disc were dropped, the water fraction showed inhibitory activity. Therefore, as a natural product for the control of powdery mildew, it was confirmed that the methanol extract of the Japanese vinegar and the water fraction of the methanol extract were the most preferable.
