Coriandrum sativum L. Hu Sui (Coriander) (leaf) Acetone, bomeol, coriandrol, cymene, decanal, decanol, decylic aldehyde, dipentene, geraniol, rutin, limonene, linalool, malic acid, nonanal, oxalic acid, phellandrene, tannic acid, terpinene, terpinolen, umbelliferone, scopoletun, coumarins, quercetin, kaepferal, aflatoxins.50-450 Eruptions of pox and measles. 

Detailed study of the coriander spice oil composition showed that the d-linalool content ranged from 60 to 70% and the hydrocarbon content was about 20%. a- and (3-pinenes, dipentene (limonene), p-cymene, a- and y-terpinenes, n-decanal, geraniol and 1-borneol were also identified as constituents of the spice oil. 

Skapska et al. (2004) observed the changes in the volatiles of coriander induced by ultra-high pressure (UHP) heat treatment in helium. The treatments did not affect the total essential oil content. The most important sensory constituent (linalool) was not significantly affected by the treatments. Several monoterpenes (sabinene, myrcene, limonene, y-terpinene and oc-terpinolene) decreased in pressurized samples and increased in non-pressurized samples. 

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],...

Thujone was discovered by E. Schweizer. C. VolckeP discovered carvone in carraway seed oil, and cineol in wormseed oil. Carvone was shown to be a ketone related to limonene by H. Goldschmidt and R. Ziirrer. Linalool was discovered by distilling coriander oil by A. Kawalier and prepared from linaloe wood (licari kamali) by H. Morin.Geraniol was discovered by O. Jacobson in oil of palma rosa. F. W. Semmler " showed that it is an olefinic terpene with an open carbon chain. Menthone was obtained from oil of peppermint by R. W. Atkinson and H. Yoshida. (Menthol was known much earlier and was analysed by Dumas in 1832.) G. Bouchardat and R. Voiry obtained terpineol from essential oils. Citronellal (an aldehyde) was discovered by F. D. Dodge.2 ...
