Amoung 10 compounds (polyhydroxy substituted N-benzoylserotonin derivatives), compound 4 shows the highest number of ε. The ε of compound 4 is high up to 11.43 × 103㎝-1M-1, which is the 2.84 times of the ε of control group, octyl salicylate. Moreover, compound 4 can absorb all the wavelength if UVB (280 nm - 320 nm), so compound 4 can provide the best protection from UVB. Additionally, this study also discovers that the compound 5 not only can absorb UVB, but also can absorb UVA.
