The researchers identified new categories of volatile sulfur compounds and other chemicals responsible for diverse scents, unlike prior beliefs claiming terpenes are accountable for the plant's smell. This finding provides a better understanding of the chemistry of Cannabis sativa L.'s aroma while contesting existing assumptions about the compounds responsible for its specific scents., according to the study. THC interacts with the brain's receptors, producing the "high" feature associated with cannabis use. Not only is the plant renowned for recreational and medicinal use, but Cannabis sativa L. has also been cultivated for various industrial purposes. For instance, hemp, a variety of Cannabis sativa L., is widely grown for its fibers, seeds, and oil. Hemp fibers are used in textiles, paper, and construction materials, while hemp seeds are used in food products and oil extraction. Recently, researchers have been studying these compounds to understand the specific chemicals responsible for the different smells in various Cannabis varieties. The study reported that scientists successfully identified specific compounds, including ß-myrcene, D--limonene, ß-caryophyllene, and terpinolene, commonly present in different varieties of Cannabis plants. These compounds are frequently employed to distinguish and label Cannabis products.reported that researchers at the terpene distributor Abstrax Tech conducted a study on 31 cannabis extracts to explore their smells more deeply. They employed various techniques such as gas chromatography, mass spectrometry, and flame ionization detection to analyze the chemicals present in the cannabis samples closely.Researchers stated: "We identified a new class of tropical volatile sulfur compounds that are major contributors to certain varieties with a strong citrus or tropical fruit aroma, while skatole , a highly pungent compound, was identified as a key aroma compound in savory/chemical varieties.” They also identified a molecule known as 321MBT, liable for the strong odor emitted by beer post its exposure to sunlight. This molecule further contributes to the distinct smell of skunk spray. The researchers spotted a chemical compound called skatole, also present in human feces and other sources. Skatole produces a savory garlic scent mixed with the more familiar aroma of cannabis, according toThe Abstrax Tech team is aspiring for their research to pave the way for selectively breeding cannabis strains with specific aromas, potentially reducing the traditional skunky smell associated with cannabis. Researchers said, "these results provide a greater understanding of the chemical composition of cannabis beyond terpenes and how these compounds contribute to the unique aromas that it produces.” "Furthermore, this catalog of compounds and their contributions to the scent of cannabis provides a new opportunity to classify varieties using key desirable aroma attributes."Cannabis sativa L. produces a wide variety of volatile secondary metabolites that contribute to its unique aroma. The major volatile constituents include monoterpenes, sesquiterpenes, and their oxygenated derivates. In particular, the compounds ß-myrcene, D--limonene, ß-caryophyllene, and terpinolene are often found in greatest amounts, which has led to their use in chemotaxonomic classification schemes and legal Cannabis sativa L. product labeling. While these compounds contribute to the characteristic aroma of Cannabis sativa L. and may help differentiate varieties on a broad level, their importance in producing specific aromas is not well understood. Here, we show that across Cannabis sativa L. varieties with divergent aromas, terpene expression remains remarkably similar, indicating their benign contribution to these unique, specific scents. Instead, we found that many minor, nonterpenoid compounds correlate strongly with nonprototypical sweet or savory aromas produced by Cannabis sativa L. Coupling sensory studies to our chemical analysis, we derive correlations between groups of compounds, or in some cases, individual compounds, that produce many of these diverse scents. In particular, we identified a new class of volatile sulfur compounds containing the 3-mercaptohexyl functional group responsible for the distinct citrus aromas in certain varieties and skatole as the key source of the chemical aroma in others. Our results provide not only a rich understanding of the chemistry of Cannabis sativa L. but also highlight how the importance of terpenes in the context of the aroma of Cannabis sativa L. has been overemphasized.Honda intiates sales of its foldable briefcase EV in the US
