The present invention is characterized in that the clove extract of the above-mentioned enzyme treatment comprises water, a lower alcohol of C1 to C2 or a lower alcohol of C1 to C2, And further characterized in that the lower alcohol is ethanol or methanol. The composition extracted in the above process may be selected from sugar alcohols, lipid loosens, Is selectively added to eliminate enzyme activity. According to the present invention, the DPPH inhibitory activity, the promotion of the generation of Type-1 procollagen in human dermal fibroblast (HDF), the prevention of skin aging and wrinkles by the effect of inhibiting the production of MMP-1 and MMP- It exhibits an improving effect and does not exhibit a change in cell survival rate, thereby securing an excellent safety. |
