오미자 추출물에 감마선을 조사하여 tyrosinase 저해, xanthine oxidase 저해 및 아질산염 소거능에 대하여 검토하였다. 오미자 추출물은 열수, ethanol, methanol 그리고 acetone등을 이용하여 추출하였으며, 감마선은 10, 20과 30 kGy로 조사하였다. 오미자 추출물은 모두 tyrosinase 저해 효과를 가지고 있는 것으로 나타났다. 감마선 조사 후 오미자 추출물에 대한 tyrosinase는 열수 추출물보다

This study was performed to investigate the effects of tyrosinase inhibition, xanthine oxidase inhibition and nitrite-scavenging effects of gamma-irradiated Schizandrae Fructus extracts from different solvents. Schizandrae Fructus was extracted by hot water, ethanol, acetone and methanol, and the extracts were irradiated 10, 20 and 30 kGy with gamma rays. All extracts from Schizandrae Fructus showed inhibition effect against tyrosinase. Tyrosinase inhibition effect of Schizandrae Fructus were higher in solvent extracts than hot water extracts by irradiation. The Schizandrae Fructus extracts had a higher inhibitory effect against xanthine oxidase, and the effect was not changed by irradiation. Nitrite scavenging activity, which was measured at various pH conditions (1.2, 3.0, 6.0), was the highest in Schizandrae Fructus extracts at pH 1.2 and 3.0. Hot water extracts provided higher nitrite scavenging effect than those of the methanol, ethanol and acetone extracts. Gamma-Irradiation may not influence on biological activites of the extracts when irradiated up to 30 kGy.
