title: Three new amides from Microlepia pilosissima.
abstract: Phytochemical investigation of 70% EtOH extract of the dry fronds of Microlepia pilosissima has resulted in isolation of three new amides, (7E)-N-(3'-hydroxyl-4'-methoxy)-phenylethyl-4-hydroxyl-cinnamamide (1), (7E)-N-(3',4',5'-trihydroxyl)-phenylethyl-4-hydroxyl-cinnamamide (2), and (7E)-N-(3',4',5'-trihydroxyl)-phenylethyl-4-methoxy-cinnamamide (3). Their structures were characterized by spectroscopic analysis and chemical method, including 1D NMR, 2D NMR, and HR-ESI-MS.
