Department of Biotechnology, 1 Department of Referigeration Engineering, Yosu National University, Yosu, Korea, 2 Department of Faculty of Food Science and Biotechnology, Pukyong National University, Pusan, Korea, 3 College of Pharmacy, Pusan National University, Pusan, Korea The growth of Enterobacteria, Lactobacillus acidophilus and L. plantarum was promoted by natural products themselves bearing antioxidative capacity and combined two, three and four kinds of them. L. acidophilus was promoted by Paeonia japonica, Acori graminei rhizoma, Aurantii nobilis pericarpium, alone, and two mixed combinations were composed of Acori graminei rhizoma and Cinnamomi cortex, Aurantii nobilis pericarpium and Puerariae radix, and three mixed combinations were formed with Cimicifugae rhizoma, Cinnamomi cortex and Glycyrrhizae radix, and four mixed combinations were made up Glycyrrhizae radix, Theae folium, Scutellaria baicalensis george and Cinnamomi cortex. There four combination promoted growth of L. acidophilus with 1.3 times than that of control, and their antioxidative capacity also higher than that of 4 times, the ratio of elimination of hydroxyl radical was more than 70% in dilution rate of 100 times. In the case of L. plantarum was promoted by Corni fructus, Nelumbo nuclfera gaertner, Sophorae flos, alone, and two mixed combinations were organized with Schizandrae fructus and Theae folium, Paeonia japonica and Epimedii herba, and three mixed combinations were combined with Corni fructus and Theae folium and Paeonia japonica, Corni fructus and Coptidis rhizoma and Schizandrae fructus, and four mixed combinations were composed of Corni fructus, Theae folium, Coptidis rhizoma, Scutellaria baicalensis george, and Corni fructus, Schizandrae fructus, Paeonia japonica, Theae folium. These four combinations assisted growth of L. plantarum with 1.5 times than that of control, and their antioxidative capacity also higher than that of 4-5 times, the ratio of elimination of hydroxyl radical was more than 75% in dilution rate of 100 times. As these combinations of natural products could activate some parts of body, they might be applied pharmaceuitcal sources, functional foods, and expected to fermentative beverages. Key words : Antioxidative capacity, natural product, combination, growth promotion, Lactobacillus sp 우리의생체에서는호흡을통한에너지의생산, 면역활동을통한병의예방, 독성물질이생체내에투여되었을때간에서의무독화과정, 생체의균형을유지하는활동, 그리고운동등과같이일상생활의한부분인정상적인생활의활동임에도불구하고이런활동으로부터 ROS(Reactive Oxygen Species) 가생산되어정상적인세포를공격하여산화시킴으로써사멸되며이러한결과로각세포는제기능을다하지못하여생체는주름지고늙어가고병들어간다 [9,12,21]. ROS 는산소의부대전자에의하여생산되며 superoxyradical *Corresponding author Tel Fax pasteur@yosu.ac.kr 이외에도 hydroxyradical, singlet oxygen 등의독성이아주강력한 ROS 가생성되고있다. 이들 ROS 의강산화력에의하여생성될수있는질병을살펴보면세포산화에의한세포의사멸, DNA 공격하여유전자의이상을일으켜암의발생, 불포화지방산이많은세포막을공격하여물질수송시스템의고장으로인한세포의사멸, LDL 산화에의한동맥경화, 간염, 아토피성피부염, 란게르한스섬의공격에의한당뇨병의발생, 수정체단백질손상으로인한백내장, 뇌세포공격에의한치매, 반점및주름등을들수있다 [8,14,15,17]. 이러한질병들은어떻게 ROS 를제거할수있는가에의존되며 SOS 항산화제 (Superoxide Scavenging Antioxidants) 를사용함으로써제거할수있다 [8]. 천연산물은그종류와성질및역할이매우다양하여옛부터아주중요한치료제로써사용되어왔다 [2,4,6,10,20,22]. 항산화력을

2 GROWTH PROMOTING EFFECTS BY NATURAL PRODUCTS 271 검증할수있는방법을사용하여 ROS 의제거기능이강한천연산물들을탐색하고이들을이용하여장내세균중에서 Lactobacillus 속 [1,16,19] 과같은세균의기능을향상시켜생체내에 probiotic 효과를증가시키도록한다면 ROS 를제거효과와더불어장내세균의균형의유지가가능하며또한천연산물자체의약리효과를이용할수있어여러가지의장점을가질것으로사료된다. Lactobacillus 속의세균은 Staphylococcus aureus, Salmonella typhimurium, Yersinia enterocolitica 및 Clostridium perfringens 등과같은병원성미생물의성장시길항효과를발휘하며, 프로바이오틱미생물은항미생물기작을경유하여장내서식하고있는병원성미생물에대한저항성을증진시키는역할도하며, 경쟁적인집락화과정을통하여위장내병원성세균이장점막에점착하는것을저해하는작용을하는것으로알려져있다 [3,11]. Lactobacillus 속의세균에의하여생성한젖산과초산같은유기산은장내 ph 를낮추어병원성미생물의성장에있어간접적으로영향을끼치며, 이들유기산에의해장의연동운동이자극을받아장관으로부터병원성미생물을제거하는역할도한다. 그리고 Lactobacillus 에의해생성되는과산화수소 (H 2 O 2 ) 는 lactoperoxidasethiocyanate system 을통하여식중독성병원성미생물의증식을억제하는 hydrocyanic acid 를방출하기도하며, 이산화탄소와 diacetyl 또한병원성미생물의성장을저해한다 [13]. 따라서본연구에서는 ROS 제거기능이강력한항산화력을가지고있는천연산물들의선별과이를이용한배합에의하여항산화력이강하면서생체내의 Lactobacillus 속의장내세균을활성화시킬수있는천연산물의배합을구성하여장의활성화를도모하고장내질환을예방할수있는천연산물의조합을구성하고자한다. 재료및방법 사용균주장내유용균주 Lactobacillus acidophilus(kctc 3145) 및 Lactobacillus plantarum(kctc 3108) 들은 KTCC 로부터분양받아사용하였다. 재료및시약균주의성장에필요한배지로서 L. acidophilus는 Difco사로부터구입한 Lactobacilli MRS broth(casein peptone g, meat extract g, yeast extract 5.00 g, glucose g, tween g, K 2 HPO g, Naacetate 5.00 g, (NH 4 ) 2 citrate 2.00 g, MgSO 4 7H 2 O 0.20 g, MnSO 4 H 2 O 0.05 g, distilled water 1000 ml, ph 6.5) 를사용하였고, L. plantarum은 MRS broth에 0.5% lactose medium을혼합한배지를사용하였으며, 250 ml의 flask로 37 o C에서 150 rpm으로교반하면서배양하였다. 유용천연산물의선별천연산물의선별은동의보감 [4], 증맥 방약합편 [6], 한방처방의구성과적용 [10], 도해상용한방처방 [2], 현대한방강좌 [20], 현대생약학 [22] 등의여러고서에수록된고처방으로부터소화기계에많이사용되는처방중에서생체를보하는기능, 해독작용, 수렴, 조혈작용, 항균작용을가지는천연산물의역할을바탕으로 30 종류를선택하여사용하였다. 천연산물의추출및조합천연산물의시료는각각의천연산물 300 g 에 3 차증류수 1500 ml 를넣어 1 시간동안열수추출한여액을 500 ml 로농축하여사용하였다. 한가지의천연산물을사용할때는각천연산물추출액을사용하였고, 두가지의천연산물의조합은각각의천연산물을 1:1 로조합한혼합액을, 세가지의천연산물의조합은각각의천연산물을 1:1:1 로조합한혼합한액을, 네가지의천연산물의조합은각각의천연산물을 1:1:1:1 로조합한혼합액을실험의시료로하고필요한량에따라사용하였다. 장내유용세균 L. acidophilus 및 L. plantarum 의활성을증가시키는천연산물군의탐색 L. acidophilus 및 L. plantarum 의배양은 250 ml 삼각플라스크에한가지, 두가지, 세가지및네가지종류의천연산물의조합시료 3ml 와세균의특성에맞는배지를 97 ml 첨가하여전체량을 100 ml 로하여멸균한후, 질소가스로충진된 glove box(jisco, J-926) 내에서, 제균필터가부착된 needle 로배양액내로질소를불어넣어탈기시키고, 전배양한균주를 0.1% 접종하여 37 o C 에서혐기배양하면서 6 시간간격으로질소가스가충진된 glove box 내에서시료를채취한후 20 배희석하여 spectrophotometer(shimadzu, UV- 2101PC) 를이용하여 660 nm 에서흡광도를측정하였고, 세균의성장정도가천연산물을넣지않은대조군보다높은천연산물을선택하였다. 용존산소분석법 (D.O. analysis method) 에의한 ROS 제거활성의측정용존산소분석법 [14] 에의한 ROS 의제거활성의측정은 100 ml 의 flask 에 linoleic acid 1 g 과 tween 40 용액을 2ml 넣고, 천연산물의조합시료 3ml 를첨가하고증류수로써최종량을 30 ml 로조정한후, 37 o C 의항온조에서 Fe 2+ ion 을첨가하고 D.O. meter(tps, Model WP-82) 를사용하여 D.O. 의감소를측정하였으며, 표준물질로서는합성항산화제인 BHA(tertbutylhydroxyanisol) 및 BHT(tert butylhydroxytoluene), 그리고 β-carotene 을사용하여천연산물의열수추출액의항산화력을 AUC(Area Under Curve) 로써비교하였다.

Hydroxyl radical 소거활성은 2-deoxyribose oxidation method 을사용하였으며즉, 시험관에 0.1 mm FeSO 4 /EDTA 용액 0.2 ml, 10 mm 2-deoxyribose 0.2 ml, 및천연산물의조합시료 0.2 ml 와 0.1 M phosphate buffer (ph 7.4) 1.2 ml, 10 mm H 2 O ml 를가하고 37 o C 의항온조에서 4 시간반응시킨후, 2.8% 의 TCA(trichloroacetic acid) 용액 1ml 를가하여반응을중지시키고, 생성되는 malondialdehyde 를 1.0% 의 TBA (thiobarbituric acid) 용액 1ml 를가하여 100 o C 에서 10 분간가열시킨후급속냉각하고 532 nm 에서흡광도를측정하였다. 총 phenol 함량및방향족의측정항산화력은 phenol 성화합물에서강하며, 또한방향족화합물의량에의하여결정되므로천연산물의조합시료의일정량을분광광도계를이용하여 280nm 에서흡광도측정하여방향족화합물의함량을측정하였고, 총 phenol 함량의분석은 Folin-Denis 법을개량하여측정한후 tannic acid 의함량으로나타내었다. 결과및고찰 용존산소분석법 (D.O. analysis method) 에의한천연산물의 ROS 제거활성용존산소분석법에의하여 30 종류의천연산물을분석한후 AUC 를계산하여기존의합성항산화제인 0.02% 의 BHA 및 0.02% 의 BHT 등과비교하였을때승마 (Cimicifugae rhizoma), 음양곽 (Epimedii herba) 은항산화력이비슷함을보 Fig. 1.
