Resum
M yrtucomvalones D-F ( 1 - 3 ), three new triketone-phloroglucinol-triketone adduct s, and three known ones ( 4 - 6 ) were obtained from Myrtus communis 'Variegata'. Compound 1 is a pair of enantiomers which was further resolved into (+)- 1 and (-)- 1 by chiral HPLC. Their structures and complete stereochemistry were established from interpretation of NMR and crystallographic data and chemical calculations. Compounds 3 , 5 and 6 showed significant antibacterial activities.
Keywords: Antibacterial activities; Myrtus communis 'Variegata'; Phloroglucinol derivatives.
