Minor Cannabinoids of Cannabis sativa L., Fabian Thomas & Oliver Kayser, 2019

Minor Cannabinoids of Cannabis sativa L. Fabian Thomas & Oliver Kayser Journal of Medical Science, 2019, 88, (3), 141-149. Doi : 10.20883/jms.367   ABSTRACT Cannabinoids from Cannabis sativa L. play an important role as natural products in clinics. The major cannabinoids compromise tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) and its decarboxylated analogs. In this review, we focus on often neglected minor cannabinoids and discuss biosynthetic and chemical degradation routes to other neglected cannabinoids in Cannabis sativa starting from THCA, CBDA and cannabichromenic acid (CBCA). Based on the literature, patents and scientific reports, essential routes for the chemical modifi cation of cannabinoids are discussed to explain [...]

L’Italie classe les fleurs de chanvre parmi les plantes médicinales, Aurélien BERNARD, NEWSWEED.fr, 8 octobre 2020

L’Italie classe les fleurs de chanvre parmi les plantes médicinales Aurélien BERNARD NEWSWEED.fr, 8 octobre 2020 https://www.newsweed.fr/italie-classe-fleurs-chanvre-plantes-medicinales/   Un arrêté du Ministère italien des Politiques agricoles, alimentaires et forestières publié en août a classé la fleur de chanvre à usage extractif (« canapa infiorescenza a uso estrattivo« ) parmi les plantes médicinales. Quelles conséquences pour le marché italien du chanvre ? Selon Giacomo Bulleri, avocat au conseil d’administration de l’association italienne de chanvre Federcanapa, les conséquences pour le secteur chanvrier italien sont importantes. D’une part, l’inclusion de la fleur de chanvre sur la liste des plantes médicinales suggère que la plante est sur le point d’être reconnue comme un produit agricole. D’autre [...]

Do medical cannabis growers attempt to produce cannabis with different cannabinoid concentrations than recreational growers?, Sharon R. Sznitman et al., 2019,

Do medical cannabis growers attempt to produce cannabis with different cannabinoid concentrations than recreational growers? Sharon R. Sznitman, Monica J. Barratt, Tom Decorte, Pekka Hakkarainen, Simon Lenton, Gary Potter, Bernd Werse and Chris Wilkins Drugs and Alcohol Today, 2019, 19, (4), 251-256, Doi : 10.1108/DAT-06-2019-0021   Abstract Purpose – It is conceivable that cannabis cultivators who grow for medical purposes aim to improve the therapeutic index of their cannabis by attempting to produce particular concentrations of CBD and/or THC. The purpose of this paper is to examine whether small-scalemedical cannabis growers differ fromthose growing for recreational reasons in terms of self-assessed concentrations of THC and CBD [...]

Quels sont les différents types d’extraction du CBD ?, par Cassandre Saveurs-CBD, 21 janv. 2020

Quels sont les différents types d’extraction du CBD ? par Cassandre Saveurs-CBD 21 janv. 2020 https://www.saveurs-cbd.fr/blogs/nos-articles-autour-du-cbd/differents-types-d-extraction-du-cbd Depuis quelques années, le CBD (cannabidiol) est devenu une substance recherchée et très appréciée, situation tout à fait compréhensible si l’on pense à ses nombreuses vertus potentielles. Ainsi, le CBD serait très bénéfique pour la santé grâce à ces différentes propriétés : antidouleur, anxiolytique, antioxydant, anti-vomitif, anticonvulsif. On le trouve sous différentes formes afin de satisfaire tous les types d’utilisateurs. Mais l’huile reste la forme la plus commune et la plus consommée. Point sur les différentes méthodes d’extraction de l’huile de CBD. L’extraction à base d’huile Cette méthode [...]

Comment les terpènes affectent les effets d’une variété de cannabis ?, Aurélien Bernard, Newsweed.fr, 12 mai 2010

Comment les terpènes affectent les effets d’une variété de cannabis ? Publié le 12 mai 2020 NEWSWEED.fr , Par Aurélien BERNARD https://www.newsweed.fr/comment-terpenes-affectent-effets-variete-cannabis/     Lorsqu’on entend le mot terpène, la première idée qui vient à l’esprit est l’odeur d’une plante. La recherche scientifique a pourtant montré que les terpènes remplissent plus qu’une unique fonction sensorielle. Les terpènes produisent ainsi des effets spécifiques sur le corps, qu’ils soient anti-inflammatoires, antibactériens, relaxants ou anxiolytiques. C’est d’ailleurs aussi pour cette raison que certaines variétés procurent un sentiment de calme et de bien-être, alors que d’autres favorisent l’énergie. Les terpènes s’insèrent ainsi complètement dans l’effet d’entourage, qui suppose que les composants [...]

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry, Matthew T. Welling et al., 2019

Developing Robust Standardised Analytical Procedures for Cannabinoid Quantification : Laying the Foundations for an Emerging Cannabis-Based Pharmaceutical Industry Matthew T. Welling, Lei Liu, Arno Hazekamp, Ashley Dowell, Graham J. King Medical Cannabis & Cannabinoids, 2019, 2, 1–13 Doi : 10.1159/000496868   Abstract The plant genus Cannabis is a prolific producer of unique pharmaceutically relevant metabolites, commonly referred to as cannabinoids. Robust and standardised methods for the quantification of cannabinoids within botanical and drug forms is a critical step forward for an emerging Cannabis- based pharmaceutical industry, which is poised for rapid expansion. Despite a growing body of analytical methods for the quantification of cannabinoids, few have [...]

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors, David B. Finlay et al., 2020

Terpenoids From Cannabis Do Not Mediate an Entourage Effect by Acting at Cannabinoid Receptors David B. Finlay, Kathleen J. Sircombe, Mhairi Nimick, Callum Jones and Michelle Glass Frontiers in Pharmacology, 2020, Volume 11, Article 359, 1-9. doi : 10.3389/fphar.2020.00359   The entourage effect was a proposed explanation for biological observations that endocannabinoid ligand activities can be modified by other lipids released from cells at the same time. An increasing volume of anecdotal reports and interest in the plant have provoked research into the activity of minor chemical constituents of the plant—including volatile terpenoids such as myrcene, a- and b- pinene, b-caryophyllene, and limonene. However, to [...]

The origins of cannabis smoking: Chemical residue evidence from the first millennium BCE in the Pamirs, Meng Ren et al., 2019

The origins of cannabis smoking: Chemical residue evidence from the first millennium BCE in the Pamirs Meng Ren, Zihua Tang, Xinhua Wu, Robert Spengler, Hongen Jiang, Yimin Yang, Nicole Boivin Science Advances, 2019, 5, eaaw1391. Doi : 10.1016/sciadv.aaw1391   Cannabis is one of the oldest cultivated plants in East Asia, grown for grain and fiber as well as for recreational, medical, and ritual purposes. It is one of the most widely used psychoactive drugs in the world today, but little is known about its early psychoactive use or when plants under cultivation evolved the phenotypical trait of increased specialized compound production. The archaeological evidence for [...]
