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.
