Myrcene, or β-myrcene, is an unsaturated natural organic hydrocarbon. It is more accurately categorized as a monoterpene. Monoterpenes are dimers of isoprenoid ancestors, and myrcene is one of the most vital.
Myrcene (or β-myrcene) is a terpene that often exists in highly aromatic plants and herbs such as hops, bay laurel leaves, thyme, lemongrass, and basil. Myrcene is defined as having an earthy, fruity clove-like aroma, but can be very strong in higher concentrations, as in heavily sprung beers.
Whereas strains like Pure Kush, White Widow, and Himalayan Gold commonly display noticeable concentrations of myrcene, these terpene levels can vary and increase from plant to plant.
Myrcene is vital in the formation of other terpenes, and it combines the antibiotic potential of other terpenes. One reason why myrcene could be so typically found in cannabis is that it has been shown to transform the permeability of cell membranes to allow more captivation of cannabinoids by the brain. This result of myrcene has been known about since the 1970s and long ago laid a rumor that eating a ripe mango before smoking would get you high.
Conferring to recent information issued by Steep Hill Labs, a foremost cannabis testing laboratory in the Bay Area, for most people ingestion of fresh mango 45 minutes before inhaling marijuana will surge the effects of that cannabis. Rev. Dr. Kymron de Cesare of Steep Hill is a believer of what he calls “overlapping synergies” amongst myrcene and other terpenes with the several cannabinoids, such as how myrcene makes THC more active.
Terpenes arise from dehydration of terpineol geraniol, naturally. It could in principle be mined from any number of plants, for example, wild thyme, the leaves of which hold up to 40% by weight of myrcene. The existing route to commercial samples is by the pyrolysis (400 °C) of β-pinene, which is attained from turpentine.
It is currently being studied for as a cure for diabetes, to obtain analgesic effect from myrcene- which possesses the ability as a pain relief without any external source such as pills, etc.- its use in sedative, non-anti-depressant, etc.
Myrcene is an important transitional utilized in the perfumery industry. It has a pleasant scent but is seldom used directly. It is also unstable in air. Samples are stabilized by the adding alkylphenols or tocopherol. It is thus more valued as an intermediate for the groundwork of flavor and perfume chemicals such as menthol, citral, citronellol, citronellal, geraniol, neroli, and linalool. A combination of myrcene with hydrogen chloride produces geranyl chloride, aryl chloride, and linalyl chloride. The reaction of these compounds with acetic acid gives geranyl acetate, nerol acetate, and linalyl acetate, respectively.
