Pinene is a collection of unsaturated bicyclic monoterpenes.Two geometric isomers of pinene are found in nature, α-pinene and β-pinene.Both are chiral. As the name suggests, pinenes are found in pines.Specifically, pinene is the major component of the liquid extracts of conifers. [3] Pinenes are also found in many non-coniferous plants such …

α-Pinene is an organic compound of the terpene class. It is one of the two isomers of pinene, the other being β-pinene. [2] An alkene, it contains a reactive four-membered ring.It is found in the oils of many species of coniferous trees, notably Pinus and Picea species. It is also found in the essential oil of rosemary (Rosmarinus officinalis) and Satureja myrtifolia (also known as Zoufa in ...

α-蒎烯（ α-Pinene），是一种有机化合物，化学式为C 10 H 16 ，为无色透明液体，微溶于水，不溶于丙二醇、甘油，溶于乙醇、乙醚、氯仿、冰醋酸等多数有机溶剂，是合成香料的重要原料，主要用于合成松油醇、芳樟醇以及一些檀香型香料，也可用于日化品以及其他工业品的加香，还可用 …

蒎烯（Pinene）是一类具有相同骨架结构的天然有机化合物，属于双环单萜，分子式C 10 H 16. 自然界存在α-蒎烯和β-蒎烯，它们之间属双键的位置异构。 这两种蒎烯是松节油的主要成分（蒎烯英文名即出自松树），也存在于其它松柏門植物中。 在针叶植物以外的种类中也发现其存在，比如一 …

Chemical structures of α- and β-pinene. These two phytochemicals exhibit diverse biological activities, leading them to various applications and uses, such as fungicidal agents, flavors, fragrances, and antiviral and antimicrobial agents [].In addition, α- and β-pinene are components of renal and hepatic drugs [].Also, α- and β-pinene are used as …

The toxicokinetics of alpha-pinene (a-pinene) were studied in humans.The study group consisted of eight healthy males, average age 31 years. They were exposed to 0, 10, 225, or 450 mg/cu m (+)-alpha-pinene or 450 mg/cu m (-)-alpha-pinene for 2 hr in an inhalation chamber. During exposure they exercised on a cycle ergometer at the rate 50 watts.

2021年10月1日 · Much smaller but nevertheless important, α-pinene – a so called monoterpene – is of high interest for medical use but also of high industrial and commercial value. α-Pinene ((1RS,5RS)-2,6,6-trimethylbicyclo[3.1.1]hept-2-ene) is a bicyclic hydrocarbon consisting of two isoprene units resulting in the sum formula of C 10 H 16.Several isomers of pinene are described in the literature (α ...
