Isolation of New Nor-isoprenoids Related to Tobacco Thunberganoids from Japanese Domestic SUIFU Tobacco

抄録

The structure of two new nor-isoprenoids, diastereomers of 1, 4-epoxy-2, 10-dihydroxy-7-isopropyl-4-methyl-5E-undecene, isolated from Japanese domestic SUIFU tobacco, has been determined mainly by ¹³C-NMR, ¹H-NMR and high resolution MS. The carbon skeleton of the new compounds indicates that they are derived from thunbergane precursors.
