  • Patent number: 10960041
    Abstract: A method for alleviating ultraviolet damage includes administering to a subject in need thereof a composition containing an ethyl acetate-extracted product of Sedum formosanum. The ethyl acetate-extracted product of Sedum formosanum is prepared by a process including the steps of (a) extracting Sedum formosanum with a solution of monohydric alcohol to obtain a alcohol-extracted product from Sedum formosanum; (b) partitioning the alcohol-extracted product with water and n-hexane to obtain an aqueous layer and a n-hexane layer; and (c) partitioning the aqueous layer obtained in step (b) with ethyl acetate, followed by collecting an ethyl acetate layer thus formed to obtain the ethyl acetate-extracted product of Sedum formosanum.
