Constituents of the higher fungi. Part XI. Boviquinone-3, (2,5-dihydroxy-3-farnesyl-1,4-benzoquinone), diboviquinone-3,4, methylenediboviquinone-3,3, and xerocomic acid from Gomphidius rutilus Fr. and diboviquinone-4,4 from Boletus(Suillus)bovinus(Linn ex Fr.) Kuntze

Abstract

Boviquinone-3, the second member of the boviquinone series, has been identified as a constituent of the basidiomycete Gomphidius rutilus Fr., in addition xerocomic acid and two new isoprenoid diquinones are described and identified. A new diquinone from Boletus(Suillus)bovinus(Linn ex Fr.) Kuntze is described and identified.
