초록

본 연구에서는 소종과 외상출혈 치료에 사용되며, 주로 간암, 간경화 등의 간 질환 치료제로 사용되어 온 산겨릅나무 추출물에서 식품 및 음료 등과 같은 기능성 식품으로서의 다양한 산업적 응용분야에 널리 응용될 수 있는 기초연구의 일환으로 산겨릅나무 추출물을 이용하여 항산화 활성, 항지질과 산화 활성, 항미생물 활성, 항보체 활성을 실험하였으며, 또한 유용한 생리활성 성분을 분리, 동정하고자 하였다. 그 결과 산겨릅나무 추출물은 DPPH free radical 소거법에 의한 항산화 활성 실험에서는 ehtyl acetate 분획 ($RC_{50}= 3.15\;{\mu}g/m{\ell}$), butanol 분획 ($RC_{50}= 5.17\;{\mu}g/m{\ell}$)에서 강한 항산화 활성을 보였다. 또한 분리된 2개의 화합물도 대조군인 ${\alpha}-tocopherol$ 이나 BHA보다 유사하거나 강한 항산화 활성을 나타냈다. linoleic acid에 대한 항지질과산화 활성 실험은 15일 째에 물층을 제외한 추출물, 분획물 및 화합물에서 높은 활성을 나타냈으며 특히 화합물 2 (85%)는 항산화 물질로 알려진 catechin (85%)과 유사한 활성을 나타내었다. 박테리아에 대한 향균실험은 Staphylococus aureus 에서만 활성을 보이지 않았을 뿐 다른 피검균에서는 높은 활성을 보였다. 하지만 대부분의 피검균에 대하여 강한 활성을 보인 ethyl acetate 분획에서 분리된 화합물 1, 2는 모든 피검균에 대해 활성을 보이지 않았다. 다만 fungal strain인 Candida albicands에 대해 각각 $250\;{\mu}g/m{\ell}$. $500\;{\mu}g/m{\ell}$의 생육 억제 농도를 나타내었다. 보체계 활성화능을 측정한 결과 물 층 24%를 제외한 다른 분획물은 10% 이하의 낮은 억제효과를 보이거나 활성이 나타나지 않았다. 산겨릅나무 ethyl acetate 분획을 silica gel이 충전된 grass open column에 넣은 후, toluene, acetone, methanol의 혼합용매로 순차용출 (stepwise)시킨 후, ODS와 silica gel을 이용하여 column chromatography를 실시함으로서 2종의 단일 물질을 얻었다. 이 화합물은 $^lH-$$^{13}C-NMR$, IR, UV, EI/FAB-Mass spectrum을 이용하여 기기분석한 결과 compound 1은 catechin으로, compound 2는 ${\rho}-Hydroxyphenethyl$ alcohol 1-O-{\beta}-_D-(6'-O-galloyl)-glucopyranoside$로 동정되었으며, 특히 compound 2의 경우 산겨릅나무에서 처음 분리되었다. 위 결과 산겨릅나무 추출물은 항산화 활성, 항지질과산화 활성, 항미생물 활성이 우수하였다. 또한 산겨릅나무 추출물을 이용한다면 식품 및 음료 등과 같은 기능성 식품으로서의 다양한 산업적 응용분야에 널리 응용될 수 있으리라 사례된다.

Acer tegmentosum (Acereaceae) has been used a source of traditional medicines for the treatment of hepatic disorders in Korea. This research was conducted to determine biofunctional activities of A. tegmentosum stem extract and to identify its bioactive components. Methanolic extract from A. tegmentosum stem was partitioned by using organic solvents, including n-hexane, ethyl acetate, n-butanol, and water. Two compounds were isolated by using an ODS column chromatography from ethyl acetate soluble fraction shown to the strongest antioxidant activity ($RC_{50}=3.15\;{\mu}g/m{\ell}$) among the fractions. The isolated compounds were analyzed by $^1H$ and $^{13}C$ NMR, IR, UV/VIS, MS spectrum data and identified as catechin, ${\rho}-Hydroxyphenethyl$ alcohol $1-O-{\beta}-_D-(6'-O-galloyl)-glucopyranoside$. The compounds have shown strong antioxidant activity, with similar activity to BHA ($RC_{50}=2\;{\mu}g/m{\ell}$). Especially, ${\rho}-Hydroxyphenethyl$ alcohol 1-O-{\beta}-_D-(6'-O-galloyl)-glucopyranoside$ was shown strong anti-lipid peroxidative activity. However, the compounds were not shown antimicrobial activities. In antimicrobial activity assays, ethyl acetate soluble fraction was effective to bacterial inhibition, such as Escherichia coli and Klebsiella pneumonia, with minimum inhibitory concentrations in $125\;{\mu}g/m{\ell}$. Otherwise, antifungal activity against Candida albicans was shown in n-hexane soluble fraction exhibiting $63\;{\mu}g/m{\ell}$ of minimum inhibitory concentration. In anticomplementary activity assays, water soluble fraction was the most effective exhibiting 24% inhibitory activity.
