The chemical constituents of Stellera chamaejasme L. were separated by comprehensive column chromatography on MCI, ODS C-18, Toyopearl HW-40C, and silica gels. Structures of the isolated compounds were determined by NMR (nuclear magnetic resonance), MS (mass spectrometry), IR (infrared spectroscopy), and quantum chemical calculations. Nine compounds were isolated from the chloroform fraction 95% ethanol extract of the titled plant and identified as chamaejaslactone A (1), stelleranoid A (2), stelleranoid D (3), stelleranoid E (4), wikstronone A (5), wikstronone C (6), chamaejasmone D (7), daphnauranol A (8), and holosericin B (9), respectively. Among them, compound 1 was characterized as the first example of a sesquiterpenoid with an unprecedented 7,8-seco-guaiane skeleton. In the in vitro bioassay, compound 1 exhibited moderate inhibitory activity against Escherichia coli-originated β-glucuronidase with an IC50 value of 51.79 ± 3.21 μmol·L-1.
