-62–-55 °C (alpha) [1]155–156 °C (alpha)[1] The chemical compound pinene is a bicyclic terpene (C10H16, 136.24 g/mol ) known as a monoterpene [1]. There are two structural isomers found in nature a-pinene and ß-pinene. As the name suggests, both forms are important constituents of pine resin; they are also found in the resins of many other conifers, and more widely in other plants. Both are also used by many insects in their chemical communication system. a-Pinene and ß-pinene are both produced from geranyl pyrophosphate, via cyclisation of linaloyl pyrophosphate followed by loss of a proton from the carbocation equivalent.

September 11, 2009
Cordata Thunb growing in Guangdong province. The chemical constituents of the essential oil from this plant were examined by means of gas-liquid chromatography-mass spectrometric technique combined with systematic separation and thin layer chromatography. As a result of the analyses, ten components were identified: four monoterpenes-a-pinene, camphene, myrcene and d-limonene; two oxygenated monoterpenes-linalool and bornyl acetate; one sesquiterpene-caryophyllene and three aldehydeketone compounds-2-undecanone, decanoyl acetaldehyde and dodecanaldehyde. The results indicate that the compositio... (read more)
