A new sesquiterpene, chlorantholide G (1 ), a new sesquiterpene dimer, elatiolactone (2 ), and 2 new diterpenes, elatiorlabdane B (3 ) and elatiorlabdane C (4 ), together with 51 known compounds, were isolated from the aerial parts of Chloranthus elatior. The new structures including their absolute configurations were mainly established by mass spectrometric, NMR, and electronic circular dichroism experiments. All isolated compounds were tested for their anti-hDHODH activity. (4S,6R)-4-hydroxy-6-isopropyl-3-methylcyclohex-2-enon
