알파-피넨 C화학적 특성, 용도, 생산

개요

연구팀은 소나무 피톤치드의 진정작용 및 수면개선 작용기전(메커니즘)을 밝히기 위해 소나무 피톤치드의 가장 대표적인 성분인 알파-피넨(α-pinene)을 이용했다. 진정-수면과 관련된 다양한 신경세포 및 동물 실험들을 통해 알파-피넨(α-pinene)의 진정-수면 효과와 메커니즘을 과학적으로 입증하였다.

용도

소나무 피톤치드의 주성분인 알파-피넨은 진정 작용와 수면개선 효과를 모두 가지고 있으며, 이러한 효과는 알파-피넨이 중추신경계의 GABA A형 수용체에 결합하여 GABA에 의한 억제성 신경전달을 연장시켜 나타내는 것으로 확인되었다.

화학적 성질

α-Pinene is the most widespread pinene isomer. (+)-α-Pinene, (1R,5R)-2,6,6-trimethylbicyclo[3.3.1]hept-2-ene, occurs, for example, in oil from Pinus palustris Mill., at a concentration up to 65%; oil from Pinus pinaster Soland and American oil from Pinus caribaea contain 70% and 70–80%, respectively, of the laevorotatory isomer, (?)-α-Pinene, (1S,5S)-2,6,6-trimethylbicyclo[3.3.1]hept-2-ene.
α-Pinene undergoes many reactions, of which the following are used in the fragrance industry: upon hydrogenation, α-pinene is converted to pinane, which has become an important starting material in the industrial processes used in the fragrance and flavor industry. α-Pinene can be isomerized to β-pinene with high selectivity for β-pinene formation. Hydration with simultaneous ring opening yields terpineol and cis-terpin hydrate. Pyrolysis of α-pinene yields a mixture of ocimene and alloocimene.
Pure α-pinene is obtained by distillation of turpentine oils. As a fragrance substance, it is used to improve the odor of industrial products.However, it is farmore important as a starting material in industrial syntheses, for example, terpineols, borneol, and camphor.

화학적 성질

α-Pinene has a characteristic odor of pine. It is turpentine-like. The oxidized material has a resin-like odor.

출처

The structure would account for the presence of four optically active and two optically inactive isomers; although only d-, l-, and dl-α-pinene are known, however; presence of one or more isomers has been reported in more than 400 essential oils; in the largest amounts it has been reported found in Achillea millefolium (d-), Artemisia tridentata (d-), Italian rosemary (l-), wild thyme (l-), French lavender (l-), coriander (d-, dl-), cumin (d, dl-), labdanum (l-), neroli (l-), lemon, Litsea cubeba (d-) and ylang-ylang (d-). It is also reported in over 200 natural products including apple, apricot, many citrus juices and peel oils, bilberry, cranberry, lingonberry, blackberry, currants, guava, raspberry, strawberry, orange, lime, grapefruit, mandarin, tangerine oils and juices, various spices, mint essential oils, carrot, celery, cooked potato, bell pepper, tomato, anise, cinnamon, cassia leaf, clove, cumin, ginger, Mentha oils, nutmeg, mace, pepper, parsley, thyme, Swiss and cheddar cheese, cream, fatty fish, fried chicken, beef fat, hop oil, rum, bourbon whiskey, tea, roasted filberts, pecans, oats, soybean, plum, mushroom, sweet and wild marjoram, starfruit, mango, tamarind, cardamom, coriander, gin, rice, litchi, calamus, dill, lovage, caraway seed, buckwheat, laurel, fennel, kiwifruit, myrtle leaf and berry, rosemary, buchu oil, Bourbon vanilla, Spanish and clary sage, nectarine, crayfish, clam, cape gooseberry, anise hyssop, angelica root oil, Roman and German chamomile oil, eucalyptus oil, bullock’s heart and mastic gum leaf and fruit oil.

용도

α-Pinene was used as standard in headspace solid-phase microextraction-gas chromatographic analysis of volatile compounds in virgin olive oils 1 . It was used in the synthesis of cesium-doped heteropolyacid having potential application in biodiesel synthesis.

정의

ChEBI: A pinene that is bicyclo[3.1.1]hept-2-ene substituted by methyl groups at positions 2, 6 and 6 respectively.

제조 방법

From turpentine, by distillation.

Aroma threshold values

Detection: 2.5 to 62 ppb. Aroma characteristics at 1.0%: terpy citrus and spicy, woody pine and turpentinelike with a slight cooling camphoraceous nutmeglike nuance, a fresh herbal lift and a tropical fruit top note.

Taste threshold values

Taste characteristics at 10 ppm: intense, woody, piney and terpy with camphoraceous and turpentine notes. It has herbal, spicy and slightly tropical mango nuances.

일반 설명

A clear colorless liquid with a turpentine odor. Flash point 91°F. Less dense than water and insoluble in water. Vapors are heavier than air. Used as a solvent.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

alpha-Pinene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.

건강위험

Harmful if swallowed, inhaled or absorbed through skin. High concentrations are extremely destructive to mucous membrane and upper respiratory tract, eyes and skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

화재위험

Special Hazards of Combustion Products: Vapor may travel considerable distance to source of ignition and flashback. Container explosion may occur during fire conditions. Forms explosive mixtures in air.

색상 색인 번호

Alpha-pinene is the major constituent of turpentine (about 80%). It exists in levogyre form in European turpentine and in dextrogyre form in turpentine found in North-Americans. Sensitization occurs mainly in painters, polishers, and varnishers, and in those in the perfume and in the ceramics industry.

Safety Profile

A deadly poison by inhalation. Moderately toxic by ingestion. An eye, mucous membrane, and severe human skin irritant. Flammable liquid. A dangerous fire hazard when exposed to heat, flame, or oxidizing materials. To fight fire, use foam, Co2, dry chemical. Explodes on contact with nitrosyl perchlorate.

효소 저해제

This cyclic monoterpene antifungal agent (FW = 136.24 g/mol; CAS 80-56- 8; 7785-70-8 for (+) -a-pinene; 7785-26-4 for (?) -a-pinene), named systematically as (1S,5S) -2,6,6-trimethyl bicyclo[3.1.1]hept-2-ene, is found in turpentine oil. (Note: a-Pinene from North American turpentine is primarily dextrorotatory, whereas European turpentine a-pinene is levorotatory.) The d-form is found in Port Oxford cedar wood oil (Chamaecyparis lawsoniana) and the l-stereoisomer is in mandarin peel oil. The boiling point of each enantiomer is 155-156°C. Target (s) : acetylcholinesterase, both (+) - and (–) -isomers inhibit, with respective Ki values of 0.15 and 0.17 mM for the bovine enzyme; CYP3A; CYP2B1; and methane monooxygenase.
