摘要
One new eudesmane sesquiterpenoid (1) named ecdysantherol A and two new benzene derivatives ecdysantherols B (2) and C (3), together with five known benzene derivatives (4–8) were isolated from the stems of Ecdysanthera rosea. The structures of the new compounds were elucidated by extensive spectroscopic methods and X-ray diffraction. The known compounds were identified by the comparison of their spectroscopic data with reported literature data. Compound 1 showed moderate antibacterial activity against the Providensia smartii with MIC value of 12.5 μg/mL. © 2014, The Author(s).
