What is Beta-Pinene?
Alpha-pinene oxidation products are also important organic intermediates. For example, 2,3-epoxypinane can be derived from 2,3-epoxypinane by rearrangement, hydrolysis, ring-opening and other reactions to give birthenal, pinanediol, pinanol hydrate, etc. A series of important products, and widely used in the fields of spices, food, drugs and resins. Therefore, choosing a suitable catalytic material according to the structural characteristics of alpha-pinene is a research hotspot in applied catalysis at present, and the development of its catalyst has experienced metal oxidation. However, most of these catalytic systems have the problems of easy loss of catalytic centers, low catalytic efficiency, complex preparation process, many side reactions, difficult separation of products and high cost. Therefore, it is of great research significance to develop a green and efficient catalytic system for α-pinene oxidation.
Alpha-pinene is a colorless transparent liquid at room temperature, volatile, insoluble in water, contains a special bicyclic double bond structure, has good biological activity and unique reaction diversity. In the fields of chemical industry and atmospheric chemistry, it is one of the important raw materials for the synthesis of chemical products such as camphor, borneol, terpineol, spices, and resins.
In recent years, the medical field has also begun to pay attention to alpha-pinene. Studies have found that the pharmacological effects of alpha-pinene are mainly anti-tumor, anti-fungal, anti-allergic and improving ulcers.
Beta-Pinene is a bicyclic monoterpene. It is an isomer of alpha-pinene and one of the main components of turpentine. The content varies with tree species, and the content of wetland pine turpentine is 28% to 35% (Ji’an, Jiangxi, China). The relative molecular mass is 136, and the molecular formula is C10H16. The molecule has a cyclobutane, an isopropyl group and an extracyclic double bond. It has similar chemical properties to α-pinene. Colorless liquid, density (20°C) 0.8712, boiling point 162-163°C. Refractive index (20°C) 1.4787, optical rotation (20°C) (in ethanol) -22.44°C. It can be used in the synthesis of linalool, nerol, geraniol, myrcenyl alcohol and its esters, novus alcohol, novutsyl acetate, citral, ionone, citronellol and aldehydes, hydroxycitronellal and its esters , New lily of the aldehyde, new lily of the valley nitrile, longanone, terpene resin, etc. It is also an important raw material for synthetic fragrances and essences.
In the study of the impact of alpha-pinene on non-small cell lung cancer, Zhang Z et al. treated A549 cells with alpha-pinene as well as paclitaxel. The outcomes revealed that α-pinene can undoubtedly promote growth cell apoptosis. This is generally due to the synergistic impact when integrated with paclitaxel. More study on the device shows that when alpha-pinene is utilized in mix with paclitaxel, the percentage of cells in the G0/G1 phase can be dramatically enhanced, and also there are adjustments in cell morphology, such as adjustments in chromatin condensation and also nuclear fragmentation, resulting in generation of tumor cell apoptosis.

Application of Beta-Pinene
Oxidation Reaction Research
The extracyclic double bond of beta-pinene can be oxidized by a variety of oxidants to synthesize a variety of spices and pharmaceutical intermediates. Different oxidants result in different oxidation products. The oxidants are mainly concentrated in ozone, potassium permanganate, peracetic acid, and selenium dioxide. , hydrogen peroxide, lead tetraacetate, etc. Nopinone, pyrinoic acid and 2,10-epoxypinane (commonly known as rosemary ether) in the product are the main oxidation products, and these three products can be prepared More spices and medicines.
- Research on Isomerization Reaction
The target product of the isomerization reaction of beta-pinene is mainly myrcene, also known as myrcene, with a chemical name of 7-methyl-3-methylene-1,6-octadiene, which has a pleasant sweet balsam Smell, can be used directly as spices. In addition, because myrcene has two conjugated double bonds in addition to a single double bond, it is chemically active and is a very important raw material and intermediate in the fragrance industry. Its conjugated double bond can be used to synthesize a series of high-grade fragrances such as geraniol, linalool, nerol and its esters through Diels-Alder reaction or selective catalytic addition reaction, and can also be used as vitamin E or conservation hormone, etc. Raw materials for biologically active substances. Addition can also be carried out on its single double bond to prepare myrcenyl alcohol, ether and ester, etc. Myrcene mainly exists in some aromatic plants in nature, the content is very low, and the cost of isolation is relatively high. Therefore, the isomerization of high-purity beta-pinene to obtain myrcene has become a research hotspot.
Beta-Pinene of Hop Aroma Components
Aroma components in hops: four major olefins, Beta-pinene, geraniol, linalool, this article is a single article on β-pinene.
Beta-pinene (β-pinene), belongs to bicyclic terpene, colorless liquid, density 0.88±0.1g/cm3, relative density 0.863-0.871, boiling point 167°C, insoluble in water and soluble in alcohol, presenting the smell of freshly harvested grass , Pine fragrance.
The threshold value of Beta-pinene in water is 140μg/L, and a large amount of Beta-pinene is lost due to high temperature during boiling, causing the content in beer to be far below the threshold value, and the contribution of boiling addition to aroma is negligible.
Question about the grassy smell of beta-pinene. We want to eliminate the grassy taste in beer. This grassy taste mainly refers to the spicy grassy taste brought by aldehydes such as acetaldehyde, while the grassy taste brought by beta-pinene is clean and soft.
Hop varieties with high Beta-pinene content
Among common hops, Centennial has the highest content, accounting for about 0.8-1.0% of hop oil, followed by Mosaic, Palisade, Simcoe, Sorachi Ace, CTZ, accounting for about 0.5-0.8% of hop oil %.
According to the utilization rate of 50%, if the content of beta-pinene is to exceed the sensory threshold, the amount of fragrant flowers added should not be less than 3‰, that is, 3g of fragrant flowers should be added to 1L of hops. With this addition amount, the content of linalool in beer will exceed 50μg/L, which can also reflect the elegant pine flavor, so the pine flavor will not be obtained only by adding hops with high beta-pinene content in brewing . Simply put, beta-pinene is very important, but there is no need to consider how to increase its content in the brewing process, because what it can do, linalool can do too.
