Abstract

The investigation of an ext. of the aerial parts of Blainvillea rhomboidea afforded, in addn. to known compds., six further melampolides, two germacrolides and four guaianolides. HPLC anal. revealed that the compds., except for one ethoxylated deriv., are natural constituents. They are sequestered by capitate glandular trichomes of the plant surface. The taxonomic relevance of the results is briefly discussed.
