Pleurotus tuber-regium was isolated from a dead trunk of Raphia farinifera (Arecaceae) in a lowland moist forest in Antsohihy, Madagascar, and the species was confirmed by molecular analysis and morphological observations.

Abstract
Pleurotus tuber-regium was isolated from a dead trunk of Raphia farinifera (Arecaceae) in a lowland moist forest in Antsohihy, Madagascar, and the species was confirmed by molecular analysis and morphological observations. The main bioactive metabolites of the mycelium extracts were identified by mass spectrometry techniques. Five structural diverse metabolites, tryptophol, pyroglutamic acid, prolyldiketopiperazine B, sporol and RKS-1778, were characterised by LC-MS qTOF analysis of the hydro-alcoholic extract. GC-MS analysis of both chloroform and ethyl acetate extracts revealed the presence of several saturated and unsaturated fatty acids and their esters derivatives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
