Abstract
Two new azulene pigments, 7-(1-hydroxy-1-methylethyl)-4-methylazulene-1-carbaldehyde (1) and 4-methyl-7-(1-methylethyl)azulene-1-carboxylic acid (2), were isolated from the fruiting bodies of the basidiomycete Lactarius hatsudake, together with one known azulene pigment (3). Their structures were determined by spectroscopic means (including 2D-NMR) and by HR-TOF-MS experiments.
