Photinia serratifolia (syn. Photinia serrulata), commonly called Taiwanese photinia^[2] or Chinese photinia is a flowering shrub or tree in the Rosaceae family of flowering plants, found in mixed forests of China, Taiwan, Japan, the Philippines, Indonesia, and India. It grows typically 4–6 m (13–20 ft), sometimes up to 12 m (39 ft), tall.^[3] Its leaves are toxic due to the presence of cyanogenic glycosides.^[4]

Pinene (C₁₀H₁₆) is a bicyclic monoterpene chemical compound.^[1] There are two structural isomers of pinene found in nature: α-pinene and β-pinene. As the name suggests, both forms are important constituents of pine resin; they are also found in the resins of many other conifers, as well as in non-coniferous plants such as camphorweed (Heterotheca)^[3] and big sagebrush (Artemisia tridentata). Both isomers are used by many insects in their chemical communication system. The two isomers of pinene constitute the major component of turpentine.

Biosynthesis[edit]

α-Pinene and β-pinene are both produced from geranyl pyrophosphate, via cyclisation of linaloyl pyrophosphate followed by loss of a proton from the carbocation equivalent.

Plants[edit]

Alpha-pinene is the most widely encountered terpenoid in nature^[4] and is highly repellant to insects.^[5]

Alpha-pinene appears in conifers and numerous other plants.^[6] Pinene is a major component of the essential oils of Sideritis spp. (ironwort)^[7] and Salvia spp. (sage).^[8]Cannabis also contains alpha-pinene.^[6] Resin from Pistacia terebinthus (commonly known as terebinth or turpentine tree) is rich in pinene. Pine nuts produced by pinetrees contain pinene.^[6]

Makrut lime fruit peel contains an essential oil comparable to lime fruit peel oil; its main components are limonene and β-pinene.^[9]

Usage[edit]

In chemical industry, selective oxidation of pinene with some catalysts gives many compounds for perfumery, such as artificial odorants. An important oxidation product is verbenone, along with pinene oxide, verbenol and verbenyl hydroperoxide. ^[10]

Pinenes are the primary constituents of turpentine.

Pinene has also been used as anti-cancer agent in Traditional Chinese medicine, also for its anti-inflammatory, antiseptic, expectorant and bronchodilator properties.^[11]
