Furanosesquiterpenoids from Lindera pulcherrima (Nees.) Benth. ex Hook. f

Abstract

The essential oil of the leaves of Lindera pulcherrima (Nees.) Benth. ex Hook. f. was examined by GC, GC/MS and NMR spectroscopy. Furanosesquiterpenoids [furanodienone (46.6%) and curzerenone (17.6%)] were the major constituents of the oil, along with furanodiene (1.8%) and curzerene (1.2%). Other constituents in significant amount were spathulenol (4.5%), β-selinene (2.0%), germacrene B (1.9%), curcuphenol (1.9%) and 10- epi-γ-eudesmol (1.8%). The composition of the oil differs from that of other Lindera species with respect to the conspicuous absence of monoterpenoids and other furan derivatives reported so far.
