Fractionation of the EtOH extract from the fruits of Schisandra sphenanthera resulted in the isolation of seven new sesquiterpenoids, 1-7, in addition to the known metabolites 8-23. Among them, schiscupatetralin A (1) possesses an unprecedented structure with a CC bond between cuparenol and tetralin. The isolated new compounds were evaluated for their anti-HSV-1 and anti-inflammatory activities. The results revealed that compound 4 exhibited anti-HSV-1 activity, while compound 6 showed a significant anti-inflammatory activity.
