The connectivity, conformation, tautomeric form, and dynamics of a new depsidone (perisalazinic acid) were characterized using one-bond 13 C13 C NMR scalar couplings (1 JCC ) obtained from the INADEQUATE experiment. Characterization of perisalazin

Individuals of Usnea fulvoreagens (Parmeliaceae, lichenised Ascomycota), a shrubby corticolous species that is widespread in Europe, East Asia and North America, produce medullary lichen acids in several distinct chemotypic patterns. One such chemoty

A carbocation cyclization/rearrangement mechanism for the biosynthesis of isothapsadiene and β-isothapsenol is shown to be energetically viable on the basis of density functional theory (DFT) calculations. In addition, for both isothapsadiene and β

Ten sesquiterpenes, many with unusual carbon skeletons, were identified in foliage of Cupressus macrocarpa. These are (-)-10-epi-beta-acoradiene; ent-widdra-2,4(14)-diene; (E)-iso-gamma-bisabolene, i.e., (4E)-4-(1,5-dimethylhex-5-enylidene)-1-methylc

The root essential oil of Ligusticum grayi Coult. & Rose (Apiaceae) was found to contain three volatile non-terpenoid hydrocarbons: the known C11 compound viridene, whose structure is hereby corrected to 1-[(2Z)-pent-2-en-1-yl]cyclohexa-1,3-diene; an

One new ent-daucadiene and enantiomers of four previously reported daucadienes or acoradienes were identified in foliage of the hybrid cypress species xCupressocyparis leylandii. The major compound is (+)-dauca-5,8-diene; minor congeners are (-)-dauc

Foliage of trees from five Chinese Cupressus species was analysed for volatile monoterpenoids, sesquiterpenoids and diterpenoids. Multivariate analysis of the terpenoid data indicated that C. gigantea is most distinct, but otherwise no obvious chemot
