摘要Two new phloroglucinol-coupled sesquiterpenoids, eucalmaidials A and B (1 and 2), were isolated from the juvenile leaves of Eucalyptus maideni, along with eight known macrocarpals (3-10), eucalyptone (11), and three known triterpenoids (12-14). Eucalmaidials A and B represent a new skeleton of phloroglucinolcoupled iphionane. Their structures were elucidated by extensive NMR spectroscopic analysis and theoretical calculation of the C-13 NMR chemical shifts. The biosynthetic pathway of 1 and 2 was also postulated. Compounds 1, 3, 5, 7, 8, and 10-14 were evaluated for their antifungal and antibacterial activities. Compound 1 exhibited antifungal activity against Candida glabrata with an IC50 value of 0.75 mu g mL(1).
