Abstract

Nemotinic acid (I; RH) and nemotin (II) have been isolated from the culture media of Poria subacida, P. colorea, and P. mutans. P. subacida also yields methyl nemotinate (I; RMe).The ene-diyne hydroxy-acid (V; RH) has been obtained from P. selecta, and the all-trans-C12-tetraene diol (VI) from P. pearsonii. The latter compound is also elaborated by the fungus Coprinus flocculosus. Daedalea juniperina produces several polyenes, one of which has been identified as all-trans-decatetraenol (VII).
