Abstract
From fruit-bodies of the Japanese mushroom Boletus laetissimus two polyene pigments boleto-crocin A and B were isolated and their structures determine d by spectroscopic methods. The compounds represent diamides of hexadecahep taenedioic acid with isoleucine and either aspartic acid or asparagine. The L-configuration of the amino acids was established after acid hydrolysis. The structures of five structurally related minor pigments were elucidated by LC-ESIMS. (C) 1998 Published by Elsevier Science Ltd. All rights reserve d.
