## Abstract Two new highly acetylated lanostaneβtype triterpenoids, coprinacin A (**1**) and coprinacin B (**2**), were isolated from the basidiomycetous strain __Coprinus cinereus__ 120. The chemical structures of **1** and **2** were elucidated by spectroscopic analyses, including 1Dβ and 2DβNMR
),14-diene ( ) and (4R,13S)-18-O-b-d-glucopyranosyllabda-8( ),14-dien-13-ol (2) have been isolated from the 95% EtOH extract of the dry fronds of Diplopterygium rufopilosum. Their structures were characterized by spectroscopic methods, including 1D-NMR, 2D-NMR, and HR-ESI-MS.
