In order to understand the chemical constituents of Neoboletus brunneissimus, eighteen compounds were isolated. On the basis of spectral data, they were identified as 5α,8α-epidoxy-(22 E,24 R)-ergosta-6,22-dien-3β-ol(1), 5α,8α-epidioxy-(22 E,24 R)-ergosta-6,9(11),22-trien-3β-ol(2),(22 E,24 R)-ergosta-7,22-dien-3β-ol(3),(24 S)-ergosta-7-en-3?-ol(4),(22 E,24 R)-ergosta-7,22-dien-3β,5α,6β-triol(5),(24 S)-ethylcholest-7-ene-3β,5α,6β-triol(6),(22 E,24 R)-ergosta-7,22-diene-3β,5α,6β,9α-tetrol(7),(22 E,4 R)-ergosta-5,7,22-trien-3β-ol(8), 3β-Oglucopyranosyl-5α,8α-epidioxy-(22 E,24 R)-ergosta-6,22-dien(9), monomethyl fumarate(10), fumaric acid(11), succinic acid(12), trans-2-decenedioic acid(13), nicotinic acid(14), nicotinamide(15), shikimic acid(16), linoleic acid-α-glyceride(17) and 1-O-β-D-glucopyranosyl-(2 S,3 R,4 E,8 E,2′R)-2-N-(2′-hydroxypalmitoyl)-9-methyl-4,8-sphingadienine(18). All compounds were isolated from N. brunneissimus for the first time, compounds 6, 9, 13 and 17 were isolated from the Boletaceae fungi for the first time.
