[Studies on chemical constituents of Lobaria kurokawae yoshim].
Six compounds have been isolated from the lichen plant Lobaria kurokawae and their structures were determined as ergosterol (1) , stictan-3beta, 22alpha-diol (2), retigeric acid B (5), retigeric acid A (6), ethyl orsellinate (3)and 3-O-methyl-1,2: 5,6-bis-O-(1 -mehtylethylidene)-d-chiro-inostiol (4) on the basis of spectral data(MS, 1H-NMR, 13C-NMR and 2D-NMR). Compounds 1-4 were isolated from this plant for the first time.
