The bioassay-guided fractionation of the MeOH extract of the flowers of Magnolia denudata led us to the isolation of six compounds identified as fargesin(1), kobusin(2), aschantin(3), magnolin(4), rel-[7s,8s,8's]-3,4,3',4'-tetra- methoxy-9,7'- dihydroxy-8,8',7.O.9'-lignan(5) and oplodiol(6), respectively. Among the isolated compounds, fargesin(1) showed most potent inhibitory effect on the melanin polymer biosynthesis in cultured B-16 mouse melanoma cell lines$(IC_{50},\;45.7\;{\mu}M)$.
