Abstract: The present invention relates to a novel compound represented by following formula 2 produced by means of marine-derived fungus Penicillium sp. and a composition for improving skin wrinkles, enhancing elasticity and skin whitening using excellent collagen synthesis promoting activity and melanin production inhibitory activity of the novel compound. In formula 2, R1 is any one selected from the group consisting of H, OH, COOH, an alkyl having 1 to 6 carbon atoms and an alkoxy having 1 to 6 carbon atoms. R1 is any one selected from the group consisting of H, OH, COOH, an alkyl having 1 to 6 carbon atoms and an alkoxy having 1 to 6 carbon atoms. R2 is any one selected from the group consisting of H, OH, COOH, an alkyl having 1 to 6 carbon atoms and an alkoxy having 1 to 6 carbon atoms. R3 is any one selected from the group consisting of H, OH, COOH, an alkyl having 1 to 6 carbon atoms and an alkoxy having 1 to 6 carbon atoms. R4 is any one selected from the group consisting of H, OH, COOH, an alkyl having 1 to 6 carbon atoms and an alkoxy having 1 to 6 carbon atoms.
