Abstract

|
The aim of this study is to evaluate several plant extracts with a view to developing UV sunscreen agents. In this study, 150 plant extracts were screened to elucidate their UV spectra using spectrophotometric method. Several plant extracts such as Phellodendron amurense, Morus alba, Rhododendron mucronulatum, Brassica alba have strong absorbency at UVA region (350nm), the suntanning wavelength. And Sophora flavescens, Caesalpinia sapper, Morus alba, Phellodendron amurense, showed absorption plateau value at UVB region (308nm), the erythema action wavelength. These extracts have a good absorbency property as synthetic filter and could be served as substitutes for synthetic UV sunscreen agents.
