Abstract

In the present study, 70% ethanol extract, the ethyl acetate fraction were prepared from citron (Citrus junos)seed and their antioxidative ability was evaluated. The yields of extract and fractions were 5.1 and 0.9% per dried powder, respectively. In the 1,1-Phenyl-2-picrylhydrazyl (DPPH) radical test, free radical scavenging activities ($FSC_{50}$) of 70 % ethanol extract, ethyl acetate fraction were 512.1 and $514.0{\mu}g/mL$, respectively. Evaluation of total antioxidant capacities ($OSC_{50}$) using $Fe^{3+}$-EDTA system. Their $OSC_{50}$ of ethyl acetate fraction were $86.5{\mu}g/mL$. this antioxidant capacities higher than that of 70% ethanol extract. but lower than that of L-ascorbic acid ($1.72{\mu}g/mL$), known as a prominent water soluble antioxidant. The cellular protective effects on the $^1O_2$-induced cellular damage of rabbit erythrocytes were evaluated and the results showed that the extract was lower than (+)-${\alpha}$-tocopherol and low concentration of ethyl acetate fraction was similar to (+)-${\alpha}$-tocopherol. but not at high concentrations of ethtyl acetate fraction. it was able to induce cellular damage at high concentration.

본 연구에서는 건조된 유자씨박 70% 에탄올 추출물 및 에틸아세테이트 분획물을 제조하고, 이들의 항산화능을 평가하였다. 유자씨박 추출물 및 분획물의 수율은 각각 5.1 및 0.9%로 나타났다. 1,1-Phenyl-2-picrylhydrazyl (DPPH) 라디칼 시험법에서 자유 라디칼 소거 활성($FSC_{50}$)은 70% 에탄올 추출물과 에틸아세테이트 분획물이 각각 512.1 및 $514.0{\mu}g/mL$를 나타냈다. 라디칼 소거활성은 (+)-${\alpha}$-tocopherol($9.0{\mu}g/mL$)보다는 비교적 낮았다. $Fe^{3+}$-EDTA계를 이용한 총 항산화능 평가에서 유자씨박 70% 에탄올 추출물 및 에틸아세테이트 분획의 $OSC_{50}$은 242.9 및 $86.5{\mu}g/mL$이었다. 유자씨박 에틸아세테이트 분획은 70% 에탄올 추출물 보다 높은 총 항산화능을 보였지만, 대조군인 L-ascorbic acid ($1.7{\mu}g/mL$)보다 낮게 나타났다. $^1O_2$로 유도된 세포 손상에 대한 보호 효과(${\tau}_{50}$)에서, 70% 에탄올 추출물은 5, 10, 25, $50{\mu}g/mL$에서 농도 의존적인 세포 보호 효과를 보였다. 유자씨박 에틸아세테이트 분획은 $5{\mu}g/mL$에서 39.8 min으로 (+)-${\alpha}$-tocopherol (36.1 min)과 유사한 세포 보호 활성을 나타났다. 그러나 $10{\mu}g/mL$ 이상에서 농도가 증가함에 따라 낮은 세포 보호 효과를 나타냈다. 결과적으로, 유자씨박 에틸아세테이트 분획물이 라디칼 소거활성이 아닌 총 항산화 활성을 통해 낮은 농도에서는 세포 보호 효과를 나타냈으나 높은 농도에서는 세포 보호 효과가 농도 의존적으로 나타나지 않았다.
