Camphor coriander

Polshkov (2001) studied the effect of storage time and condition on the composition of coriander oil after 1, 2, 4, 6, 9 and 12 months by GC-MS analysis. In the fresh specimen, the monoterpene hydrocarbons, y-terpinene and a-pinene, were detected in considerable amounts and camphor, linalyl acetate and geranyl acetate in smaller amounts. Aldehydes (neral, 2-decenal and undecenal) were also found. During 1 year of storage in the dark, the composition of the oil changed... 

Coriander Coriandrum sativum (S)-Linalool, (-)-camphor, geraniol 95,100... 

Composition ISO lists 65-78% linalool, a-pinene (3-7%), y-terpinene (2-7%), camphor (4-6%), limonene (2-5%), geranyl acetate (1-3.5%), geraniol (0.5-3%), a-terpi-neol (0.5-1.5%) and myrcene (0.5-1.5%) [75] as the main components of coriander fruit oil. Further constituents can be linalyl acetate, bomeol, citronellol, nerol, ter-pinene-4-ol, additionally monoterpene hydrocarbons and aliphatic aldehydes [76, 77], The latter are the main components of the weed (cilantro) oil and their amount is higher in unripe coriander fruits. E-2-tridecanal is held responsible for the bug-like odour of these unripe fruits ( bug dill ) [78], Lamparsky and Klimes have performed an exhaustive analysis which also led to the detection of interesting heterocyclic trace constituents [79],... 

Site-specific natural isotope fractionation (SNIF) NMR, which determines different (D/H), isotope ratios from the NMR spectra, has been used to characterize essential oils derived from a variety of botanicals (lavender, spike lavender, bose de rose oil, bergamont, germanium, clary sage, petit grain, coriander, Formosan, and camphor oil) and geographical regions versus synthetically produced oils. These SNIF-NMR results combined with DA allowed the natural and synthetic oils to be unambiguously indentified. ...
