Abstract：Chinese herbal medicines as additives in cosmetic can both keep the properties of cosmetic and have maintaining, health protection and remedial effect. Some of the Chinese herbal medicines can absorb ultraviolet and cure sunburn. This article mainly studies the spectral properties of several kinds of Chinese herbal medicine additives in cosmetic by ultraviolet and visible spectrophotometer, and analyses the ultraviolet absorption of the Chinese herbal medicine additives. It was shown that gynostemma pentaphyllum can absorb ultraviolet very well. It can be a promising natural additive in the health protection cosmetic. Codonopsis pilosula, floss chrysanthemum indicum, radix scutellariae and radix glycyrrhizae can absorb ultraviolet. They can also be the additives, while ligusticum wallichii can’t absorb ultraviolet, so it can not be used as the sunburn protection additive.
