Four bitter compounds, lophiroside A1, A2, B1 and B2, were isolated from the bark of Lophira alata, and their structures were determined by chemical and spectral methods.They are rare types of cyanoglucosides containing a cyanomethylene group in the benzoylated and/or cinnamoylated aglycones.The threshold amount for bitterness of each compound was estimated as 10 μg by a filter paper tasting method.Key Word Index: Lophira alata; Ochnaceae; bitter substance; cyclohexylcyanomethylene glucoside; lophiroside.
