辣根过氧化物酶（HRP），一个高度研究的成员过氧化物酶
在许多其他生物活性中，已知家族催化
总的类黄酮和酚类底物的氧化，包括
槲皮素另一方面，槲皮素因其
抗氧化活性，在紫外线外部辐射的情况下，
由于它是一种优良的紫外线吸收剂，因此部分地以预防的方式存在。
因此，本研究的目的是研究槲皮素的氧化
在紫外强制降解条件下，即连续条件下，磷酸盐缓冲液中的HRP，
延长UV-B辐射。结果表明，当UV-B辐射时，
影响HRP的活性和槲皮素氧化的总速率，
HRP，它可能有很小的影响，它对它的较长的UV-B-照射
周期（>30 min）。[鸣谢。这项工作得到了该部的支持

Horseradish peroxidase (HRP), a highly-investigated member of the peroxidase
family has been known, among many other biological activities, to catalyze
the oxidation of flavonoids and phenolic substrates overall, including
quercetin. On the other hand, quercetin is very well known for its
antioxidant activities, which in the case of UV external radiation is
exibited partly in a preventive manner since it is an excellent UV-absorber.
Therefore the aim of this investigation is to study quercetin oxidation by
HRP in phosphate buffer under the conditions of UV-stress, i.e. continuous,
prolonged UV-B irradiation. The results show that while UV-B irradiation
affects the activity of HRP, and the overal rate of quercetin oxidation by
HRP, it probably has very little effect on it for longer UV-B-irradiation
periods (>30 min). [Acknowledgements. This work was supported by the Ministry
