''[[Cannabis sativa]]'' L. is an intriguing plant that has been exploited since ancient times for recreational, medical, textile and food purposes. The plant's most promising bioactive constituents discovered so far belong to the [[terpenoid]] and [[cannabinoid]] classes. These specialized metabolites are highly concentrated in the plant aerial parts, and their chemical characterization is crucial to guarantee the safe and efficient use of the plant material irrespective of which use it is. This study investigates for the first time the use of vacuum-assisted headspace solid-phase microextraction (Vac-HSSPME) as a [[Sample (material)|sample]] preparation process in an analytical protocol based on Vac-HSSPME combined to fast [[gas chromatography–mass spectrometry]] (GC-MS) analysis that aims at comprehensively characterizing both the terpenoid and cannabinoid profiles of ''[[Cannabis]]'' [[inflorescence]]s in a single step ...

With an increasing appreciation for the unique pharmacological properties associated with distinct, individual [[cannabinoid]]s of ''[[Cannabis sativa]]'', there is demand for accurate and reliable quantification for a growing number of them. Although recent methods are based on highly selective [[chromatography]]–[[mass spectrometry]] technology, most are limited to a few cannabinoids, while relying on unnecessarily sophisticated and expensive [[High-performance liquid chromatography|ultra-high-performance liquid chromatography]] and [[tandem mass spectrometry]]. Here we report an optimized, simple extraction method followed by a reliable and simple high-performance liquid chromatography (HPLC) method for separation. The detection is performed using a [[Time-of-flight mass spectrometry|time-of-flight mass spectrometer]] that is available in most natural products research laboratories ...

Industrial [[hemp]] (''[[Cannabis sativa]]'' L.) is a plant native to Asia and is considered to be a primary source of food, textile fiber, and medicines. It is characterized by containing minimal concentrations of [[Tetrahydrocannabinol|Δ<sup>9</sup>-tetrahydrocannabinol]] (THC), which is the main [[Psychoactive drug|psychoactive chemical]] component, and [[cannabidiol]] (CBD), a non-psychoactive substance. In most European countries, the maximum concentration legally allowed for cultivation is 0.2% of THC, and it is currently under debate whether to increase this level to 0.3%. Moreover, in many countries its production is being regulated and legalized, increasing the need for a rapid analysis method ...

[[Cannabis sativa|''Cannabis sativa'' L.]] is one of the oldest known medicinal plants, cultivated for at least 10,000 years for several agricultural and industrial applications. However, the plant became controversial owing to some psychoactive components that have adverse effects on human health. In this review, we analyze the trends in [[cannabis]] research for the past two centuries. We discuss the historical transitions of cannabis from the category of "herbal medicine" to an [[Cannabis (drug)|illicit drug]] and back to a medicinal product [[Legality of cannabis|post-legalization]]. In addition, we address the new-age application of immuno-suppressive and anti-inflammatory cannabis extracts for the treatment of [[limswiki:COVID-19|COVID-19]] inflammation. We further address the influence of the legal aspects of [[cannabis cultivation]] for medicinal, pharmaceutical, and biotechnological research ...

The aim of this study was to investigate whether the [[Cannabis concentrate|cannabis extract]] obtained from [[cannabis]] [[Inflorescence|flowers]] that contain the maximum allowed level of [[mycotoxin]]s affects human safety and health. For that purpose, a novel method of [[Chromatography#Liquid chromatography|liquid chromatography]] with [[tandem mass spectrometry]] (LC-MS/MS) was developed and validated for the determination of [[aflatoxin]]s and [[Ochratoxin|ochratoxin A]] (OchA) in cannabis extracts to demonstrate that this analytical method is suitable for the intended experimental design.

Products containing [[Delta-8-Tetrahydrocannabinol|delta-8-tetrahydrocannabinol]] (Δ<sup>8</sup>-THC) became widely available in most of the United States following the [[2018 Farm Bill]], and by late 2020, those products were core products of [[hemp]] processing companies, especially where [[Tetrahydrocannabinol|delta-9-tetrahydrocannabinol]] (Δ<sup>9</sup>-THC) use remained [[Decriminalization of non-medical cannabis in the United States|illegal]] or required [[ Cannabis (drug)|medical]] authorization. Research on experiences with Δ<sup>8</sup>-THC is scarce, and some state governments have prohibited it because of this lack of knowledge. We conducted an exploratory study addressing a broad range of issues regarding Δ<sup>8</sup>-THC to inform policy discussions and provide directions for future systematic research.

Over the last few decades, a growing body of evidence has increasingly showed the therapeutic capabilities of ''[[Cannabis]]'' plants. These capabilities have been attributed to the specialized secondary metabolites stored in the glandular [[trichome]]s of female [[inflorescence]]s, mainly [[Cannabinoid|phytocannabinoids]] and [[terpenoid]]s. The accumulation of these metabolites in the flower is versatile and influenced by a largely unknown regulation system, attributed to genetic, developmental, and environmental factors. As ''Cannabis'' is a [[Dioecy|dioecious]] plant, one main factor is fertilization after successful pollination. Fertilized flowers are considerably less potent, likely due to changes in the contents of phytocannabinoids and terpenoids.

'''"[[Journal:The cannabis terpenes|The cannabis terpenes]]"''' | |||
[[Terpene]]s are the primary constituents of essential oils and are responsible for the aroma characteristics of the ''[[Cannabis]]'' plant. Together with [[cannabinoid]]s, terpenes illustrate a potential synergic and/or [[entourage effect]], with their interactions having only been speculated on for the last few decades. Hundreds of terpenes have been identified that additionally add to the overall cannabis sensory experience, contributing largely to the consumer’s experiences, as well as the market price. These terpenes also enhance many therapeutic efforts, especially as aromatherapy. To shed light on the importance of terpenes in the [[cannabis industry]], the purpose of this review is to morphologically describe sources of cannabis terpenes and to explain the [[biosynthesis]] and diversity of terpene profiles in different cannabis [[chemotype]]s.
