초록
탈지 산사(Crataegus pinnatifida Bunge)에서 추출된 에테르 추출물의 항산화성이 확인됨에 따라, 각 페놀성 추출물, 즉 유리형, 용성 에스테르형 및 불용성 물질의 분리 및 동정이 TLC, gel column chromatography, MS 및 H-NMR에 의해서 시도되었다. 시료의 유리형 페놀산 추출물에서는 caffeic acid, protocatechuic acid 및 pyrogallol, 용성 에스테르형 페놀에서는 caffeic acid 및 phloroglucinol, 불용성 페놀산에서는 protocatechuic acid, phloroglucinol 등이 각각 동정되어 산사의 주된 항산화성 물질임이 확인되었다.
Based upon the antioxidative effectiveness of ether extracts of defated Crataegus pinnatifida B., phenolic antioxidative components were separated by gel column chromatography and identified by MS and H-NMR. Two or three individual compounds were found in free, soluble and insoluble bound phenolic acids, respectively and they were identified as caffeic acid, protocatechuic acid, phloroglucinol and pyrogallol.
