The results of the ability of anti-oxidation scavenging DPPH free radical shows that polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) have the generally better ability of anti-oxidation than control group, in which the IC50 of compound 1-10 ranges 8.75 to 18.02 μg/ml and the IC50 of trolox is 13.04 μg/ml. The abilities of anti-oxidation of compound 1, 4, 5, 7, and 10 are all better than the control group, trolox. Among all, compound 10 has the best ability of anti-oxidation (IC50 is 8.75 μg/ml). This study also discovers that the ability of scavenging DPPH free radical is strongly related to the number and the position of hydroxyl.

在清除DPPH自由基的抗氧化能力结果显示,相较於对照组水溶性维生素E之IC50值13.04 μg/ml,多羟基取代之N-色洛冬宁苯甲醯胺衍生物(化合物 1 ~ 10),皆具有相当不错的抗氧化能力,十种醯胺化合物的 IC50值介於8.75 ~ 18.02 μg/ml之间,化合物1、4、5、7、10的抗氧化能力效果皆优於对照组水溶性维生素E的IC50值,其中又以化合物10的效果最佳(IC50值8.75 μg/ml),而清除DPPH自由基的能力发现与羟基的数量及其位置有关。

In the study of UV absorbing test, polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) shows better ability to absorb UV and shows wider range of absorbing UVB than control group, octyl salicylate. With respect to octyl salicylate, octyl salicylate can abosorb the highest wavelength up to 306 nm under UVB (wavelength ranges 280 nm ~320 nm), and the ε is 4.03 × 103 ㎝-1M-1. However, the ε of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10) under 306 nm range 4.14 × 103 ~ 11.45 × 103㎝-1M-1. It is reasonable that the compounds in this study can not only absorb the individual wavelength amoung the wavelenght of UVB, but also absorb wider range of wavelength.

Standard enthalpy changes of the initial pyrolysis process of ethylbenzene were computed by five methods (UAM1, UHF/3-21G*, UB3LYP/3-21G* and UB3LYP/6-31G*). UB3LYP/6-31G* due to its accuracy compared to the experimental values was chosen to calculate the thermodynamic and kinetic parameters of the process at different temperature ranges (298 ~ 1573 K). The computation results showed that ethylbenzene began to pyrolyze at 973 K and the main product was styrene.
