The Chemical Constituents of Basidiomycetes Boletopsis grisea

Eight phenolic constituents including three specific 5 lipoxidase inhibitors 3 (4 acetoxyphenyl) 1, 2, 4, 7, 8 pentacetoxy dibenzofuran (1), 3 (4 acetoxyphenyl) 7, 8 dihydroxy 1, 2, 4, triacetoxy dibenzofuran (2), 1, 2 diacetoxy 3 (4 hydroxyphenyl) 4, 7, 8 trihydroxy dibenzofuran (3), and 2,3 diacetoxy 4′, 4″, 5, 6 tetrahydroxy p terphenyl (4), 1,4 benzenediol (5), 4 hydroxybenzoic acid (6), p anisic acid (7), 4 hydroxybenzaldehyde (8), together with thioacetic anhydride (9) and 1 O β D glucopyranosyl (2S, 3R, 4E, 8E, 2′R) 2 N (2′ hydroxypalmitoyl) 9 methyl 4,8 sphingadienine (10) were isolated from the fruiting bodies of Basidiomycetes Boletopsis grisea (Peck) Bond. Singer (Polyporaceae).Their structure were elucidated by spectroscopic evidence.
