From the aerial parts of Prunus prostrata (Rosaceae), the following new compounds were isolated: 5-(b-D-glucopyranosyloxy)-2-(3-hydroxybutyl)-l,3,3-trimethylcyclohexene [1], 4-(b-D-glucopyranosyloxy)-3-(3-methyl-2-butenyl)benzoic acid [2], fraxinol 6-b-D-galactopyranoside [3], and 6,7-dihydroxy-5-methoxycoumarin 6-b-D-glucopyranoside [4]. Their structures were established by means of fabms and a combination of homo- and hetero-nuclear 2D nmr techniques. Twelve known compounds, never previously isolated from this genus, were also found in this plant.
