초록

본 연구는 국내산 왕벚나무 수피를 건강기능식품 소재로서 활용 가능성을 확인하기 위하여 용매별 추출물에 대한 특성 분석과 항산화 활성을 평가하였다. 용매별 소재의 아미노산과 지방산 분석을 통하여 성분함량 및 조성 차이를 확인하였고, 항산화 활성 비교를 위해 총 폴리페놀 함량, 총 플라보노이드 함량, DPPH 라디칼 소거능, ABTS 라디칼 소거능, FRAP 활성을 측정 및 비교 후 상관관계를 분석하였다. 아미노산 분석 결과, 열수 추출물, 30% 에탄올 추출물, 70% 에탄올 추출물에서 13종의 아미노산이 검출되었고, 주요 아미노산으로 aspartic acid, arginine, proline으로 분석되었으며, 총 아미노산 함량은 각각 0.17%, 0.16%, 0.09%로 확인되었다. 지방산 분석 결과, 포화지방산(SFA)이 열수 추출물, 30% 에탄올 추출물, 70% 에탄올 추출물에서 62.7-66.7%로 높은 조성비를 보였고, 확인된 지방산은 열수 추출물에서 behenic acid (C22:0)을 제외한 13종의 지방산이 검출되었으며, 30% 에탄올 추출물과 70% 에탄올 추출물에서 14종 지방산이 검출되었다. 주요 지방산은 열수 추출물, 30% 에탄올 추출물, 70% 에탄올 추출물에서 palmitic acid (C16:0)로 확인되었고, 총 지방산 함량은 각각 0.66 mg/g, 2.46 mg/g, 10.04 mg/g으로 70% 에탄올 추출물에서 가장 높았다. 총 플라보노이드와 총 폴리페놀 함량은 열수 추출물, 30% 에탄올 추출물, 70% 에탄올 추출물에서 각각 727.70-769.87 mg QE/g, 309.24-348.09 mg GAE/g이었다. 항산화 활성 측정 결과 열수 추출물, 30% 에탄올 추출물, 70% 에탄올 추출물에서 DPPH 라디칼 소거능은 0.05-1 mg/mL 농도에서 각각 14.42-81.77%, 16.85-83.38%, 19.33-81.12%의 결과를 보였고, ABTS 라디칼 소거능은 0.05-1 mg/mL 농도에서 각각 6.32-89.55%, 16.14-70.61%, 8.99-92.08%의 결과를 보였으며, FARP 활성은 0.05-0.5 mg/mL 농도에서 각각 0.32-2.91, 0.07-0.61, 0.39-3.43으로 나타나 농도 의존적으로 항산화 효과를 증가시키는 것을 확인하였다. 용매별 추출물의 총 플라보노이드 함량, 총 폴리페놀 함량과 항산화 활성 간의 상관관계를 분석한 결과, 높은 양(+)의 상관성을 보였다(P<0.01). 본 연구결과를 통해 왕벚나무 수피 추출물을 이용한 건강기능식품 소재 개발의 기초 자료로 활용될 수 있을 것으로 사료된다.

This study aimed to investigate the amino acid content, fatty acid composition, total flavonoid and phenol contents, and antioxidant activities of Prunus yedoensis Matsum. bark extracts using various extraction solvents. Through amino acid analysis, 13 amino acids were detected in extracts obtained using hot water, 30% ethanol, and 70% ethanol. The major amino acids were identified as aspartic acid, arginine, and proline, and the total amino acid content was 0.17%, 0.16%, and 0.09%, respectively. Fatty acid analysis showed a saturated fatty acid (SFA) ratio of 62.7-66.7% in extracts obtained using hot water, 30% ethanol, and 70% ethanol, with the primary fatty acid identified as palmitic acid. The total flavonoid and polyphenol contents were 727.70-769.87 mg quercetin equivalent (QE)/ g and 309.24-348.09 mg gallic acid equivalent (GAE)/g, respectively, in extracts obtained using hot water, 30% ethanol, and 70% ethanol extracts. Measurements of antioxidant activity confirmed that extracts obtained using hot water, 30% ethanol, and 70% ethanol extracts increased the antioxidant effect in 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, and ferric reducing antioxidant power (FRAP) in a concentration-dependent manner. A high correlation was observed between the total flavonoid content, total polyphenol content, and antioxidant activities of the extracts. This study provides data and novel insights for the development of functional food materials using P. yedoensis Matsum. bark extracts.
