Three Novel Crustulinol Esters, Saponaceols A—C, from Tricholoma saponaceum

Abstract

Three novel triterpene esters, saponaceols A (1), B (2), and C (3) were isolated from the fruiting body of the fungus Tricholoma saponaceum, and their structures were elucidated on the basis of extensive NMR experiments. Saponaceol A (1) exhibited moderate inhibitory activity against HL-60 cells.
