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.
