The following discussion is provided to aid the reader in understanding the disclosure and is not admitted to describe or constitute prior art thereto.
Cannabis is one of the most popular recreational drugs and it has recently seen significant changes to its legality within the United States and other countries. The Cannabis plant has many unique traits, such as its ability to biosynthesize a wide variety of secondary metabolites including tetrahydrocannabinol (THC), cannabidiol (CBD), as well as a plethora of monoterpenes, monoterpenoids, sesquiterpenes, and sesquiterpenoids. Although typically consumed for the psychoactive effects brought upon by THC, and more recently proposed therapeutic effects of CBD, recent interest within the greater cannabis community has turned to terpenes and other compounds that give cannabis its unique scent and flavor. Like THC and CBD, the concentrations and types of terpenoids present are heavily influenced by both genetics and external stress on the plant throughout the growth cycle. Through selective breeding, growers have been able to produce plants with a wide variety of aromas, all primarily due to the presence of compounds of the terpene class.
The major or primary aroma compounds contributing to the odor of cannabis as described in scientific and popular literature are β-Myrcene, α- and β-Pinene, D-Limonene, β-Caryophyllene, Terpinolene, and Humulene, although over 200 compounds have been described throughout the scientific literature. The presence of various secondary metabolites, terpenes, terpenoids, sesquiterpenes, and sesquiterpenoids results in Cannabis products having a wide variety of aromas and flavors with remarkable depth and complexity. One of the most popular organoleptic descriptors in Cannabis is the presence of a “Gassy” aroma—that is, an aroma that emulates that of gasoline. This aroma is described as a piercing, sulfuric, sharp odor on the nose that is often associated strongly with strains of the OG family, although other families can likewise have similar odors. It is also commonly considered an indicator of freshness and/or quality of a cannabis product. Although cannabis breeders can breed plants to express specific odors, such as this odor, the exact chemical composition that leads to it is unknown. Within the cannabis community, much focus has been on terpenes, sesquiterpenes, and their oxygenated derivatives. However, attempts at emulating certain aromas using artificial blends with many of these compounds in ratios determined from gas chromatographic data have fallen short when capturing the complete aroma profile of a given cannabis strain. One strain family that has been notoriously difficult to emulate is the OG family, pioneered by the strain OG Kush. This strain is characterized by what is often described as the quintessential aroma of cannabis—a strong, sulfuric, gassy odor that has a high substantivity—the ability for an odor to be detectable over a period of time. This strain has subsequently been cross-bred with other strains, leading to a plethora of strains that now possess this pungent odor. Attempts at using chemical characterization methods such as gas or liquid chromatography have not led to an obvious origin of this odor in cannabis, and thus remains somewhat of a mystery regarding what compound, or compounds, contribute.

Methods for analyzing and/or identifying the compounds that contribute to a gassy aroma associated with a product, e.g., a cannabis product, are also provided herein. The methods include analyzing the constituents of a product having a gassy aroma using various devices and methods including, but not limited to, gas chromatography/time-of-flight mass-spectrometer (GC/TOF-MS), two-dimensional gas chromatography-time of flight mass spectrometry (2DGC-TOF MS), flame ionization detector (HD), sulfur chemiluminescence detector (SCD), gas chromatography/mass spectrometry (GC/MS), gas chromatography with atomic emission detector (GC/AED), gas chromatography/flame ionization detection/olfactometry (GC/FID/olfactometry) or high performance liquid chromatography (HPLC), or a combination of any two or more thereof.
Cannabis strains and compositions with varying degrees of gassy aroma may be analyzed using 2-dimensional gas chromatography equipped with a time-of-flight mass-spectrometer (TOF-MS), flame ionization detector (FID), and a sulfur chemiluminescence detector (SCD). It has now been surprisingly and unexpectedly discovered that a correlation exists between the organoleptic response, i.e. how ‘gassy’ a given strain smells to the human nose, and the concentration of certain organosulfur compounds. Such organosulfur compounds may include, but are not limited to, prenyl mercaptan (3-methylbut-2-ene-1-thiol), 2-methylthiophene, 3-methylthiophene, dimethyl disulfide, diprenyl disulfide, 3-methyl-2-buten-1-yl thiolacetate, 3-methyl-1-[(3-methyl-2-buten-1-yl)sulfanyl]-2-butene, prenylmethylthiol (1-(methylsulfanyl)-3-methyl-2-butene), prenyl thioacetate, thiogeraniol ((E)-3,7-dimethyl-2,6-octadien-1-thiol), and dimethyl sulfide. It was discovered that the odors of these organosulfur compounds coupled with terpene compounds present in a strain may yield the particular ‘flavor’ of the gas present. Although low in relative concentration compared to the terpenes, the organosulfur compounds were found to have a significant impact on aroma and flavor. The methods for identification and analysis of the odor-producing compounds described herein can advantageously be used to guide cultivators for targeting and producing plants, clones, or plant cells with or without specific aromas associated with them, as well as develop formulations of food and beverages when targeting a unique gassy aroma or odor.

Suitable samples of the cannabis plant material can be placed in a bottle and the gases in a headspace bottle, can be collected using headspace tools and injected into a gas chromatography-sulfur chemiluminescence detector combined device, using an inert gas such as nitrogen as carrier gas for the gas chromatography, and performing qualitative and quantitative detection through a sulfur chemiluminescence detector. The cannabis samples can be incubated and agitated at suitable temperature (e.g., 40-150° C.) prior to collection of the headspace gas sample. In some embodiments, the cannabis sample may include cannabis flower material, such as dried flower, dried, and ground flower, a wet flower, or a flower extract. In some embodiments, the flower material may be cured. In some embodiments, the flower material may be uncured.

The present invention, thus generally described, will be understood more readily by reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention.
Various embodiments will be further clarified by the following examples, which are in no way intended to limit this disclosure thereto.
Samples of cannabis flowers were curated from different sources. All samples were stored in clear, colorless scintillation vials in a −20° C. freezer to ensure minimal loss of volatiles and decrease thermal decomposition. All samples were dried and cured prior to procurement.
200 mg of each curated flower sample from Example 1 was transferred to 2DGC vials followed by mechanically grinding with a spatula. Vial caps were then crimped onto each vial.
Twelve cannabis cultivars were analyzed using 2-dimensional gas chromatography, mass spectrometry, and sulfur chemiluminescence to determine the chemical origin of the gassy odor in cannabis. GC x GC analysis was performed using the INSIGHT reverse fill flush flow modulator (Sepsolve Analytical) in conjunction with a 7890B GC (Agilent technologies) and BenchTOF TOF-MS (Markes International). Detection and quantification of sulfur-bearing compounds was performed using an Agilent 8355 sulfur chemiluminescence detector (SCD). Sample introduction was performed using the Centri sample preparation platform (Markes International).
Samples were incubated and agitated at a temperature of 45° C. for 10 minutes, followed by six 1 mL headspace injections from the sample vial to a cryogen free cold trap held at 25° C. After the six injections were complete, the cold trap was rapidly heated to 300° C. to desorb the sample in a narrow band onto the analytical columns. The GC x GC column configuration was a polar to apolar setup. The GC oven ramp rates used were as follows: The oven was initially set to 45° C. and held for 3 minutes. The oven was then ramped at a rate of 5° C. per minute to 90° C., followed a 2.0° C. ramp rate to 130° C., followed last by a 5° C. ramp rate to 240° C. The modulation period set for the flow modulator was 7.2 seconds.
Data was collected, integrated, and analyzed using the ChromSpace software platform (Sepsolve Analytical). A 5-point calibration curve was calculated using 1-Pentanethiol (DCG Partnership I, LTD) to quantify the compounds detected from the SCD. The solutions were prepared using serial dilution of the analytical standard with pentane. As sulfur atoms provide an equimolar response to the amount present in the SCD, any analytes containing sulfur were quantified using the 1-Pentanethiol standard calibration curve. The calibration curve showing detector response versus mass is shown in
Table 1 summarizes value masses used for each calibration point and the measured SCD peak volume.
The cultivars were chosen with varying degrees of gassy aroma to determine the chemical origin. A clear correlation was observed between concentration of prenyl mercaptan and prenyl thioacetate (chemical structures shown in
Five cannabis fragrance and aroma experts were asked to rate the odors of each strain using a blind olfactory test. Table 2 summarizes the cultivars, concentrations of compounds of interest, and the organoleptic response of each flower.
Of all cultivars, Bacio Gelato was found to possess the highest concentration of prenyl mercaptan as shown in Table 2. This high concentration results in an intense, piercing, gassy aroma. Prenyl thioacetate is also present in the sample, which further contributes to the aroma of this cultivar.
A second eluent of interest in the SCD data suggested a compound with similar functionality based on the mass spectral data (
The remaining cultivars were screened for the presence of prenyl thioacetate and their respective concentrations as shown in Table 2.
These results confirm the origins of the gassy odor in cannabis and explain how the aroma can be modulated through coupling of other compounds present in the cannabis plant.
The following blend compositions, namely, Composition A, Composition B, Composition C and Composition D, and were prepared for their prenyl mercaptan and 2-methylthiphene content as well as other components. The compositions are summarized in Table 3.
