Four prenylated acetophenones 2,6-dihydroxy-4-geranyloxyacetophenone ( 1), 4-geranyloxy-2,6,β-trihydroxyacetophenone ( 2), 2,6-dihydroxy-4-geranyloxy-3-prenylacetophenone ( 3), and 4-geranyloxy-3-prenyl-2,6,β-trihydroxyacetophenone ( 4) have for the first time been isolated from Melicope obscura ( 1 and 2) and Melicope obtusifolia ssp. obtusifolia var. arborea ( 3 and 4). The distribution of prenylated acetophenones in Rutaceae is reviewed and the results, including the new records, indicate that prenylated acetophenones are valuable as chemotaxonomic markers for the subfamily Rutoideae, tribe Xanthoxyleae sensu Engler.
