Two Halogenated Sesquiterpenoids from the Fruits of Alpinia oxyphylla

Abstract Two new halogenated eremophilane‐type sesquiterpenoids, (11 S )‐ and (11 R )‐12‐chloronootkaton‐11‐ol ( 1 and 2 , resp.), together with five known sesquiterpenoids, nootkatone ( 3 ), 7‐epiteucrenone B ( 4 ), oxyphyllenodiol A ( 5 ), oxyphyllenodiol B ( 6 ), and alpinenone ( 7 ), were isolated from the EtOH extract of the fruits of Alpinia oxyphylla Miq . The structures were elucidated based on the analyses of their spectroscopic data.
