COUMARINS AND OTHER CONSTITUENTS OF PRUNUS-PROSTRATA

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