title: Terpenoids and a diarylheptanoid from Zingiber ottensii.
abstract: Four new terpenoids and a diarylheptanoid were isolated together with 16 known compounds from rhizomes of Zingiber ottensii. The structures of the new compounds were determined to be 1,10,10-trimethylbicyclo[7,4,0]tridecane-3,6-dione (1), (E)-14-hydroxy-15-norlabda-8(17),12-dien-16-al (2), (E)-labda-8(17),12,14-trien-15(16)-olide (3), (E)-14,15,16-trinorlabda-8(17),11-dien-13-oic acid (4), and rel-(3R,5S)-3,5-dihydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(3, 4-dihydroxyphenyl)heptane (5) by spectroscopic evidence.
