Zanthoxylum piperitum 종자의 치아우식균 Streptococcus mutans에 대한 항균활성 Antimicrobial Activity of Seeds of Zanthoxylum piperitum against Oral Pathogen Streptococcus mutans원문보기
치아우식균으로 알려져 있는 Streptococcus mutans에 대한 초피(Zanthoxylum piperitum)의 항균활성을 조사하기 위해, 뿌리, 줄기, 잎, 과피, 그리고 종자 부분을 methanol, ethyl acetate, hexane, methylene chloride등의 유기용매로 추출한 후 그 추출물의 항균활성을 $1{\sim}3$ mg/disc 농도범위에서 측정하였다. 그 결과, 종자의 경우만 활성이 나타났으며 특히 methylene chloride 추출물에서 비교적 높은 항균활성이 확인되었다. 초피종자의 항균활성이 종자의 정유성분을 추출할 경우에도 회수되는지를 조사하기 위해 초피종자 및 초피과피로부터 정유성분을 추출하고 이들의 S. mutans에 대한 항균활성을 측정하였다. 이때 두 정유성분 모두는 종자의 methylene chloride 추출물 보다 더 강한 항균효과를 보였다. 이 정유성분들의 S. mutans에 대한 최소저해농도(MIC)를 액체배양으로 측정한 결과, 초피종자 정유성분의 MIC는 0.3 mg/ml 로, 또한 초피과피 정유성분의 MIC는 4 mg/ml로 나타났다. S. mutans에 대한 항균활성이 가장 높게 나타난 종자의 정유성분을 박층크로마토그래피 방법으로 7가지 분획으로 나누어 그 항균효과를 서로 비교 조사한 결과, 다섯번째 분획(CS-SD-E)의 항균활성이 다른 분획들의 항균활성에 비해 상대적으로 높았으나, 분획 전의 정유성분에 비해서는 모두 항균활성이 낮았다. 초피종자의 항균활성성분을 조사하기 위해, 초피종자의 methylene chloride 추출물과 초피종자 정유성분을 GC-MS로 비교 분석하였다. 초피종자의 methylene chloride 추출물에서는 S. mutans에 대한 항균활성이 이미 보고된 물질로서 carvacrol (0.24%), ${\beta}$-caryphyllene (1.72%), ${\alpha}$-humulene (0.88%)등이 검출되었고, 초피종자 정유성분에서는 sabinene (1.57%), linalool (1.55%), citronellal (13.67%), terpinene-4-ol (0.45%), citronellol (3.69%), geraniol (0.9%), linalyl acetate (1.35%), ${\beta}$-caryophyllene (1.35%), ${\alpha}$-humulene (0.7818%) 및 ${\delta}$-cadinene (0.67%) 등이 S. mutans에 대한 항균활성이 보고된바 있는 물질로서 확인되었다. 이상의 연구결과는 초피종자가 S. mutans에 대해 항균활성을 가지며, 수증기 증류를 통해 확보하는 종자의 정유성분 회수가 이러한 항균물질을 추출하는 효과적인 방법임을 시사한다. 아울러 본 연구결과는 초피종자 유래의 정유성분이 S. mutans에 의해 발생하는 치아우식의 예방에 활용될 수 있음을 시사한다.

Antimicrobial activity of Zanthoxylum piperitum was investigated against Streptococcus mutans that causes dental caries. Although the methylene chloride extract of seeds exhibited higher antimicrobial activity than other organic solvent extracts, including methanol, ethyl acetate, and hexane extracts of pericarps or seeds of Z. piperitum, essential oils prepared from both seeds and pericarps possessed more potent inhibitory activity than the methylene chloride extract of seeds. The minimal inhibitory concentrations (MICs) of the essential oils of seeds and pericarps were 0.3 mg/ml and 4.0 mg/ml against S. mutans, respectively. When the seed essential oil was further separated into seven fractions (CS-SD-A${\sim}$CS-SD-G) by thin layer chromatography (TLC), all fractions exhibited lower antimicrobial activity than the essential oil. To understand the antimicrobial ingredients of Z. piperitum, seeds the gas chromatography-mass spectrometry (GC-MS) data of the methylene chloride extract of seeds was compared with those of the seed essential oil (CS-SD). Whereas the methylene chloride extract of seeds contained carvacrol (0.24%), ${\beta}$-caryophyllene (1.72%), and ${\alpha}$-humulene (0.88%), which were previously known to inhibit growth of S. mutans, the seed essential oil contained sabinene (1.57%), linalool (1.55%), citronellal (13.67%), terpinene-4-ol (0.45%), citronellol (3.69%), geraniol (0.9%), linalyl acetate (1.35%), ${\beta}$-caryophyllene (1.35%), ${\alpha}$-humulene (0.78%), and ${\delta}$-cadinene (0.67%) in this regard. These results indicate that Z. piperitum seeds possess various inhibitory substances against S. mutans, and an effective method to isolate the active ingredients from the seeds is to prepare the essential oil. These results also suggest that the essential oil of Z. piperitium seeds may be applicable to preventing dental caries.

제안 방법
piperitum (Table 2). To compare fur ther the antimicrobial activity between the seed essential oil and the pericarp essential oil, the minimal inhibitory concentrations (MICs) of both essential oils against growth of S. mutans in the BHI broth were investigated. As shown in Fig.
대상 데이터
Zanthoxylum piperitum were collected from GyeongSan, Gyeongsangbuk-do, Korea and dried at room temperature. The extract from each portions of Zanthoxylum piperitum pre pared and a voucher specimen of pericarps, seeds is pre served at the Department of Pharmacy, Catholic University of Daegu, Korea.
성능/효과
8 mg/ml [7, 23], respectively. These results demonstrate that although Z. piperitum seeds contain various antimicrobial components, which could be isolated either by methylene chloride extraction or water dis tillation, the effective method to gain the antimicrobial in gredients from the seed is to prepare essential oils by water distillation.
0 mm for the 2 mg/disc concentration. These results indicate that seeds of Z. piperitum have antimicrobial activity against S. mutans, and suggest that the extraction of seeds with methylene chloride might be an effective method to isolate the antimicrobial ingredient(s) from the seeds.
