Identification of Terpenoid Chemotypes Among High (-)-trans-D9- Tetrahydrocannabinol-Producing Cannabis sativa L. Cultivars, Justin T. Fischedick,

Identification of Terpenoid Chemotypes Among High (-)-trans-D9- Tetrahydrocannabinol-Producing Cannabis sativa L. Cultivars Justin T. Fischedick Cannabis and Cannabinoid Research, 2017, 2, 1, 34-47 DOI: 10.1089/can.2016.0040   Abstract Introduction : With laws changing around the world regarding the legal status of Cannabis sativa (cannabis) it is important to develop objective classification systems that help explain the chemical variation found among various cultivars. Currently cannabis cultivars are named using obscure and inconsistent nomenclature. Terpenoids, responsible for the aroma of cannabis, are a useful group of compounds for distinguishing cannabis cultivars with similar cannabinoid content. Methods : In this study we analyzed terpenoid content of cannabis samples obtained from a [...]

Cannabis sativa : The Plant of the Thousand and One Molecules, Christelle M. Andre, 2016

Cannabis sativa : The Plant of the Thousand and One Molecules Christelle M. Andre, Jean-Francois Hausman and Gea Guerriero Frontiers in Plant Science, 2016, Volume 7, Article 19. doi:10.3389/fpls.2016.00019   Cannabis sativa L. is an important herbaceous species originating from Central Asia, which has been used in folk medicine and as a source of textile fiber since the dawn of times. This fast-growing plant has recently seen a resurgence of interest because of its multi-purpose applications : it is indeed a treasure trove of phytochemicals and a rich source of both cellulosic and woody fibers. Equally highly interested in this plant are the pharmaceutical and [...]

Molecular Targets of the Phytocannabinoids-A Complex Picture, Paula Morales et al., 2017

Molecular Targets of the Phytocannabinoids-A Complex Picture Paula Morales, Dow P. Hurst, Patricia H. Reggio Progress in the Chemistry of Organic Natural Products, 2017 ; 103: 103–131. doi:10.1007/978-3-319-45541-9_4. 1 Introduction For centuries, hashish and marihuana, both derived from the Indian hemp Cannabis sativa L., have been used for their medicinal, as well as, their psychotropic effects. Phytocannabinoids are oxygen containing C21 aromatic hydrocarbons found in Cannabis sativa L. To date, over 120 phytocannabinoids have been isolated from Cannabis, including two compounds, (−)-trans-Δ9-tetrahydrocannabinol (Δ9-THC) and (−)-trans-Δ8-THC (Δ8-THC) that have been shown to bind to cannabinoid receptors and elicit the characteristic psychotropic effect associated with Cannabis [1].

Chemical evidence for the use of multiple psychotropic plants in a 1,000-year-old ritual bundle from South America, Melanie J. Miller et al., 2019

Chemical evidence for the use of multiple psychotropic plants in a 1,000-year-old ritual bundle from South America Melanie J. Miller, Juan Albarracin-Jordan, Christine Moore, and José M. Capriles PNAS June 4, 2019, 116 (23) 11207-11212; first published May 6, 2019 https://doi.org/10.1073/pnas.1902174116 Significance Humans have a long history of using natural resources, especially plants, to induce nonordinary states of consciousness. Imbibing substances derived from plants have been linked to ancient and elaborate knowledge systems and rituals. While archaeological evidence of the consumption of psychotropics, such as alcohol or caffeine, dates back thousands of years, evidence of the use of other psychoactive substances has been more [...]

A reliable and validated LC-MS/MS method for the simultaneous quantification of 4 cannabinoids in 40 consumer products, Qingfang Meng et al., 2018

A reliable and validated LC-MS/MS method for the simultaneous quantification of 4 cannabinoids in 40 consumer products Qingfang Meng, Beth Buchanan, Jonathan Zuccolo, Mathieu-Marc Poulin, Joseph Gabriele, David Charles Baranowski PLoS ONE, 2018, 13, 5, e0196396. https://doi.org/10.1371/journal.pone.0196396   Abstract In the past 50 years, Cannabis sativa (C. sativa) has gone from a substance essentially prohibited worldwide to one that is gaining acceptance both culturally and legally in many countries for medicinal and recreational use. As additional jurisdictions legalize Cannabis products and the variety and complexity of these products surpass the classical dried plant material, appropriate methods for measuring the biologically active constituents is paramount to ensure [...]

Cannabis Pharmacy. The Practical Guide to Medical marijuana, Michael Backes, 2014

Cannabis Pharmacy. The Practical Guide to Medical marijuana Authoritative, evidence-based information, plus advice on treating dozens of ailments and conditions Michael Backes, foreword by Andrew Weil, MD Black Dog & Leventhal Publishers, New York, 2014   Foreword by Andrew Weil, M.D. From the perspective of someone who has studied traditional therapies as a career, it is surprising that cannabis ever left our medicine cabinets, since the plant has been used for millennia in cultures throughout the world as a curative for ailments of both mind and body. In 1942, the American Medical Association (AMA) fought to keep it as part of the U.S. Pharmacopeia. In spite [...]
