Abstract

  A new depside, tentatively named NA-3, was isolated from Nephroma arcticum. Some other new compounds, 1-(O-α-D-glucopyranosyl)-3S,25R-hexacosanediol and a new amino acid, solorinine, were reported from Solorina crocea, and the following compounds were detected from Protousnea species: 5-propylresorcinol derivatives and bis (2,4-dihydroxy-6-propylphenyl) methane together with known compounds, sekikaic acid and divaricatic acid.
