Abstract
Ten new diarylheptanoids (2, 3, 4, 5a-d, 6, 7, and 8) have been isolated from an extract of Ottelia alismoides. The structures of these previously unknown metabolites were determined by NMR spectroscopic analysis. A previously unknown, hydroxylated analog of the known otteliones A and B (1a and 1b)-namely, 3a-hydroxyottelione (13)-was also isolated. The 1H NMR analysis of the Mosher esters of alcohols derived from otteliones A and B (S-17/R-17 and S-20/R-20) are also reported.
