울산지역에서 생산된 단감의 품종 및 부위의 생리활성을 체계적으로 조사하고자, 주요성분과 70% 에탄올 추출물의 전자공여능 등을 분석한 결과는 다음과 같다. 일반성분 함량은 수분 $77.68{sim}84.65%$, 조회분 $0.3{sim}0.6%$, 조지방 $0.29{sim}0.39%$, 조단백질 $0.52{sim}0.61%$로 나타났다. 확인된 유기산 및 유리당은 각각 malic acid, citric acid, succinic acid, fumaric acid 및 glucose, fructose, sucrose 이었다. 지방산은 linolenic acid, vaccenic acid, palmitic acid가 주된 지방산이었고, 무기질의 함량은 K이 $84.9{sim}103.7mg%$로 가장 높아 전체 무기질의 약 60% 이상을 차지하였다. 비타민 C, 총페놀성화합물 및 총플라보노이드 함량은 각각 139.91, 169.36 및 60.79mg%로 부유과피에서 가장 높았다. 전자공여능 및 xanthine oxidase 저해활성은 부유과피가 각각 $30.6{sim}91.2$ 및 $26.3{sim}91.9%$로 가장 높았고, 아질산염소거능은 과피가 $51.0{sim}76.4%$로 과육에 비해 높았으며, 품종별 차이는 없었다.
This study was performed to confirm the physicochemical properties and physiological activities according to cultivar and parts of Ulsan sweet persimmons. The proximate composition of the sweet persimmons was moisture $77.68{sim}84.65%$, crude ash $0.3{sim}0.6$, crude fat $0.29{sim}0.39$ and crude protein $0.52{sim}0.61%$. Confirmed organic acids and free sugars in sweet persimmons were malic, citric, succinic, and fumaric acids, along with fructose, glucose and sucrose. The major fatty acids were linolenic, vaccenic and palmitic acids. Also, K is the highest mineral in sweet persimmons that accounts for the majority of mineral, more than 60% as $84.9{sim}103.7mg%$. Contents of vitamin C, total phenolic compounds and flavonoids were the highest in Fuyu peel as 139.91, 169.36 and 60.79mg%, respectively, Electron donating ability and xanthine oxidase inhibition were the highest in Fuyu peel as $30.6{sim}91.2$ and $26.3{sim}91.9mg%$, respectively. Nitrite scavenging activity was higher in peel than flesh as $51.0{sim}76.4mg%$ with slight difference depending on cultivar.
