Lonicera japonica Thunb , is an herbaceous plant of Caprifoliaceae family. Previous studies have demonstrated that Lonicera japonica has antioxidative activities. Clitoria ternatea, commonly known as butterfly pea, is a plant species belonging to the family Fabaceae and also has antioxidant effects. The purpose of this thesis is to study the growth effect of Lonicera japonica Thunb and Clitoria ternatea water extract on Hs68 cells, and to research whether the free radicals produced by ultraviolet light have anti-oxidation ability.
