Abstract
Two new eleven-membered and three new seven-membered vibsane-type diterpene s, named vibsanin L (1) and 14-hydroxyvibsanin F (2), and vibsanin I (3), 1 4R*,15-epoxyvibsanin C (4) and 14S*,15-epoxyvibsanin C (5) respectively hav e been isolated from Viburnum odoratissimum collected in Taiwan. Their stru ctures have been elucidated by spectroscopic analyses and comparison of Nuc lear magnetic resonance method (NMR) data with those of the previously repo rted vibsane-type diterpenes. High performance liquid chromatography (HPLC) analyses indicated that the methanol extract of V. odoratissimum collected in Tain an contained no neovibsanines, characteristic chemicals occurring in V. awabuki.
