A new germacrane-type sesquiterpenoid (1) and a new alkamide (2), as well as six known compounds (3-8) were isolated from the capitula of Chrysanthemum morifolium cv. Fubaiju. The new structures were elucidated by comprehensive spectroscopic analysis and quantum chemical calculations. The known structures were characterised via 1D NMR data compared with the already existing literature data. Among the isolates, compound 5 showed inhibitory activity against human lung cancer A549 cells and human hepatoma HepG2 cells with the IC50 values of 19.50 ± 1.23 and 23.24 ± 1.30 µM, respectively, and compound 8 exhibited inhibitory effect on RSV infection with IC50 value of 12.50 ± 1.02 µM.
