Two New Pigments from the Fruiting Bodies of the Basidiomycete Lactarius deliciosus

Two new, red‐colored azulene pigments, 7‐(1,2‐dihydroxy‐1‐methylethyl)‐4‐methylazulene‐1‐carbaldehyde ( 1 ) and 7‐acetyl‐4‐methylazulene‐1‐carbaldehyde ( 2 ), were isolated from the fruiting bodies of the basidiomycete Lactarius deliciosus, together with a related, known compound ( 3 ). Their structures were established on the basis of spectroscopic evidence including 2D‐NMR experiments.
