C10H16 (136.1251936)


Dipentene appears as a colorless liquid with an odor of lemon. Flash point 113 °F. Density about 7.2 lb /gal and insoluble in water. Hence floats on water. Vapors heavier than air. Used as a solvent for rosin, waxes, rubber; as a dispersing agent for oils, resins, paints, lacquers, varnishes, and in floor waxes and furniture polishes. Limonene is a monoterpene that is cyclohex-1-ene substituted by a methyl group at position 1 and a prop-1-en-2-yl group at position 4 respectively. It has a role as a human metabolite. It is a cycloalkene and a p-menthadiene. Limonene is a natural product found in Teucrium montanum, Xylopia aromatica, and other organisms with data available. Limonene, (+/-)- is a racemic mixture of limonene, a natural cyclic monoterpene and major component of the oil extracted from citrus rind with chemo-preventive and antitumor activities. The metabolites of DL-limonene, perillic acid, dihydroperillic acid, uroterpenol and limonene 1,2-diol are suggested to inhibit tumor growth through inhibition of p21-dependent signaling, induce apoptosis via the induction of the transforming growth factor beta-signaling pathway, inhibit post-translational modification of signal transduction proteins, result in G1 cell cycle arrest as well as cause differential expression of cell cycle- and apoptosis-related genes. Limonene is a metabolite found in or produced by Saccharomyces cerevisiae. A naturally-occurring class of MONOTERPENES which occur as a clear colorless liquid at room temperature. Limonene is the major component in the oil of oranges which has many uses, including as flavor and fragrance. It is recognized as safe in food by the Food and Drug Administration (FDA). See also: Cannabis sativa subsp. indica top (part of); Larrea tridentata whole (part of). Constituent of many essential oils. (±)-Limonene is found in many foods, some of which are common oregano, nutmeg, herbs and spices, and summer savory. Dipentene is found in carrot.

Alpha-Terpinene is one of four isomers of terpinene (the other three being beta terpinene, gamma terpenine, and delta terpinine or terpimolene) that differ in the position of carbon-carbon double bonds. Alpha-Terpinene belongs to the class of organic compounds known as menthane monoterpenes. These are monoterpenes with a structure based on the o-, m-, or p-menthane backbone. p-Menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. alpha-Terpinene is a naturally occurring monoterpene found in allspice, cardamom, and marjoram. alpha-Terpinene is a constituent of many essential oils with oil from Litsea ceylanica being is a major source (20\\\\%) of it. alpha-Terpinene has been found in Citrus, Eucalyptus and Juniperus species, and cannabis plants (PMID:6991645 ). ±-Terpinene is a flavouring agent and is produced industrially by acid-catalyzed rearrangement of ±-pinene. It has perfume and flavoring properties but is mainly used to confer a pleasant odor to industrial fluids. Alpha-terpinene is one of three isomeric monoterpenes differing in the positions of their two double bonds (beta- and gamma-terpinene being the others). In alpha-terpinene the double bonds are at the 1- and 3-positions of the p-menthane skeleton. It has a role as a volatile oil component and a plant metabolite. It is a monoterpene and a cyclohexadiene. alpha-Terpinene is a natural product found in Xylopia aromatica, Xylopia sericea, and other organisms with data available. One of three isomeric monoterpenes differing in the positions of their two double bonds (beta- and gamma-terpinene being the others). In alpha-terpinene the double bonds are at the 1- and 3-positions of the p-menthane skeleton. Alpha-terpinene, also known as 1-isopropyl-4-methyl-1,3-cyclohexadiene or 1-methyl-4-(1-methylethyl)-1,3-cyclohexadiene, is a member of the class of compounds known as menthane monoterpenoids. Menthane monoterpenoids are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, alpha-terpinene is considered to be an isoprenoid lipid molecule. Alpha-terpinene is a camphoraceous, citrus, and herbal tasting compound and can be found in a number of food items such as summer savory, cabbage, pot marjoram, and wild celery, which makes alpha-terpinene a potential biomarker for the consumption of these food products. Alpha-terpinene can be found primarily in saliva. Alpha-terpinene exists in all eukaryotes, ranging from yeast to humans. α-Terpinene (Terpilene) is a monoterpene found in the essential oils of a large variety of foods and aromatic plants such as Mentha piperita. α-Terpinene is active against Trypanosoma evansi and has the potential for trypanosomosis treatment. α-Terpinene has antioxidant and antifungal properties[1][2][3][4]. α-Terpinene (Terpilene) is a monoterpene found in the essential oils of a large variety of foods and aromatic plants such as Mentha piperita. α-Terpinene is active against Trypanosoma evansi and has the potential for trypanosomosis treatment. α-Terpinene has antioxidant and antifungal properties[1][2][3][4].

   

Terpinolene

Terpinolene (TPO), also known as alpha-terpinolene or isoterpinene, belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, terpinolene is considered to be an isoprenoid lipid molecule. Terpinolene is a very hydrophobic monoterpenoid, practically insoluble in water, and relatively neutral. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes in plants is known to occur mainly through the methyl-erythritol-phosphate (MEP) pathway in the plastids (PMID:7640522 ). Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Terpinolene is one of the constituents of turpentine and an isomer of terpinene. It appears colourless to pale yellow liquid. Alpha-terpinolene has been identified as an abundant monoterpene in the essential oil of Cannabis sativa plants (PMID:6991645 ). There are more than 140 known terpenes in cannabis and the combination of these terepenoids produces the skunky, fruity odor characteristic of C. savita. Although common in cannabis cultivars, terpinolene is typically found in relatively low amounts. On the other hand, the concentration of terpinolene can be has high as 30\\% of the essential oil. It is thought that terpinolene offers a mildly sedative effect and can reduce anxiety (PMID:28826544 ). In particular, terpinolene is a central nervous system depressant that has been shown to induce drowsiness (PMID:23339024 ). Terpinolene has been demonstrated to prevent LDL oxidation and is of potential interest in the treatment of atherogenesis and coronary artery disease (PMID:28826544 ). Terpinolene exhibits antifungal and larvicidal properties (PMID:28826544 ). Terpinolene is also an effective anti-microbial agent, particularly against E coli and Staphylococcus bacteria (PMID:16402540 ). Terpinolene is also employed as a fragrence ingredient in lotions, insect repellents (similar to other terpenes), perfumes, and soaps. Terpinolene is also a constituent of many other essential oils e. g. Citrus, Mentha, Juniperus, Myristica species. Parsnip oil (Pastinaca sativa) in particular, is a major source (40-70\\%). Terpinolene is a sweet, citrus, and fresh tasting compound. It produces a floral, woody or herbal aroma reminiscent of pine needles. In addition to being found in various plant essential oils, terpinolene is found in a few different foods and spices, such as allspice, apples, sage, rosemary, parsnips, nutmegs, and wild carrots and in a lower concentration in sweet bay, star anises, turmerics, apricots, cumins, evergreen blackberries, red bell peppers, and caraway. Constituent of many essential oils e.g. Citrus, Mentha, Juniperus, Myristica subspecies Parsnip oil (Pastinaca sativa) is a major source (40-70\\%). Flavouring ingredient. Terpinolene is found in many foods, some of which are coriander, ceylon cinnamon, pine nut, and caraway.
