Definitions

  • taxonomic classification In biology, the study of life, all living organisms are systematically organized into seven categorically ranked groups known as taxonomic classification.
  • the taxonomic classification hierarchy is as follows: kingdom, phylum, class, order, family, genus, and species. Human beings, for example, are taxonomically classified as the species homo sapiens. Similarly, marijuana is classified as the species Cannabis sativa L. ("cannabis"). Marijuana flowers are known for being abundant in cannabinoids, chemical compounds that interact with the human body due to the presence of cellular receptors belonging to the endocannabinoid system (“ECS”), present in all mammals.
  • ECS endocannabinoid system
  • the ECS can be thought of as the molecular gateway that cannabinoids specifically bind to, located throughout body, such as the brain as well as the peripheral and central nervous systems. Cannabinoids are produced by mammals as well as plants. There are two types of cannabinoids the ECS is capable of interacting with: (1) endogenous endocannabinoids; and (2) exogenous phytocannabinoids. Endogenous endocannabinoids refer to a specific group of biochemical compounds produced within a mammalian body. Exogenous phytocannabinoids refer to a specific group of biochemical compounds produced within a plant.
  • cannabinoids Beyond cannabinoids and their effect on the ECS, the human body also digests, absorbs, and interacts with many other substances that are biologically produced by the cannabis species.
  • cannabis plants make hundreds, possibly thousands, of biochemical compounds called natural products.
  • natural products inclusively refers to the entire profile of chemicals and proteins biologically made, or biosynthesized, during the lifecycle of a plant.
  • Cannabinoids only represent one class of natural products in cannabis, and are comprised of hundreds of substances.
  • terpenoids are another common class of natural products, known for their aromatic structures.
  • cannabis “cultivators” people who specialize in growing and selectively breeding cannabis plants for desired characteristics, continued to breed new varieties
  • varietals within the cannabis species. As used in this patent, varietals are at the smallest end of subspecies classification. As a result of cannabis domestication, there are arguably at least five sub-species groupings before the point in which plants break off into varietal designation: three marijuana groups, including "indica,” “sativa,” “hybrid;” “ruderalis;” and hemp.
  • Marijuana varietals were bred to produce high levels of the psychoactive cannabinoid, delta-9- tetrahydrocannabinol ("THC").
  • Varietals that are within the indica grouping supposedly induce a sedative physiological effect, and are physically characterized by a short, bushy appearance, and a leaf shape of five chubby leaflets.
  • strains in the sativa grouping supposedly create an energizing physiological effect, and are physically characterized by taller, thinner branches and a leaf shape of seven longer, skinny leaflets.
  • a hybrid strain is a strain that has been bred to induce both types of effects, a cross between an indica strain and a sativa stain.
  • Ruderalis is the name given to a group of cannabis plants that appear in the wild.
  • the hemp varietals have industrial uses such as in textiles and paper, as hemp cultivators prized a fibrous structural integrity over THC production. Fully understanding the relationship these sub-species groupings have to each other as well as the cannabis species require more R&D.
  • Varietals are colloquially referred as "strains,” “cultivars,” or “genetics.” These colloquial terms were developed by underground cultivators in attempt to distinguish one cannabis plant from another at the subspecies level, beyond the hemp distinction. Note that the colloquial use of the word “genetics” has no relation to the scientific meaning of genetics. In science, genetics refers to the study of genes, the strings of molecules known as deoxyribonucleic acid (“DNA”) that make up the genetic code that serves as a blueprint to life. Genome is the word used to refer to all the genes contained by an individual organism. Technically, each truly unique varietal has its own genome, also known as a genotype.
  • DNA deoxyribonucleic acid
  • a phenotype In nature, it is possible for any given genotype to have several possible physical manifestations of the same genes.
  • the varying observable physical expression of the genotype is called a phenotype.
  • the genome is the DNA blueprint, the phenotype is what is physically expressed by the organism in response to its environment. In other words, a phenotype represents one possible iteration of the representative genotype. Phenotypic expression is often affected by the aforementioned epigenetic and environmental factors.
  • organisms can be identified and classified at the subspecies level through analyzing genotypes or phenotypes and comparing them to known reference data sets called standards. Standards are a collection of selected data points that can serve as a baseline of comparison for an unknown sample. Standards can exist for any identifiable characteristic and are not limited to the subject of genetics.
  • Parameters are quantitative numbers that provide boundaries for analyzing data so that relevant conclusions can be drawn about the data. For example, cultivators unknowingly created standards for physical traits when comparing differences such as leaf size, leaflet number, or plant height between indica and sativa varietals. The parameters of seven leaflets per leaf and five leaflets per leaf were respectively used as a way of classifying cannabis at the subspecies level as sativa or indica.
  • Phenotypes and genotypes are independent of each other, meaning that organisms with the same genotype could have different phenotypes expressed; while those with the same phenotype could have different genotypes.
  • the same genes can give rise to different cannabis morphologies, i.e. physical traits, due to differences in environmental factors.
  • Two cannabis plants may be clones of each other, but each plant can be so affected by its growth conditions such as water, light, nutrients that different phenotypes are expressed.
  • Phenotypes can be characterized by structural or biochemical differences.
  • phenotypes Differences between phenotypes can be visible to the naked eye or exist at the microscopic or molecular level; whereas genotypes purely exist at molecular (without technical manipulation). Generally, microscopic and molecular traits can be visualized and analyzed with technology. Verifying whether the genes of each plant are the same or different often requires decoding ("sequencing") the DNA of both plants and comparing their genotypes, a very time consuming and expensive process that requires skilled scientists. Cannabis cultivators and distributors primarily analyze and report select natural product levels, which are due to differences in both phenotype and genotype.

  • cannabis provides many health benefits. It is suspected that the cannabinoid and natural product ratios produced by indica varietals provide medical benefits for anxiety or insomnia; and that sativa varietals provide medical benefits for depression. Because the cannabis plant is such a complex species, more comprehensive standards are needed so that these types of conclusion can be verifiably drawn. Medical and scientific R&D must be conducted to verify the perceived varietal correlations noted by patients and cannabis users. Before advanced R&D can take place, varietals and their resulting phenotypes must be taxonomically identified at the subspecies level.

We therefore propose that this important ratio is a good Quality Assurance parameter as well as an identity marker for Cannabis material.

  • Panel (B) a completely independent dataset of samples (Presented by Jeffrey Raber, PhD at the 2016 MJ Business Conference and Expo, Science Symposium) with a collection of terpenoid values determined for each Cannabis Flower sample is plotted in the same way as (A). The Prnl Score and Prn2 Score axes are similarly scaled to that of (A). The overall pattern of the data is strikingly similar to that of Panel (A).

  • a set of terpenoid standards was used to assign the peaks to each terpenoid and to quantify the amounts in each sample. It is apparent that most of the samples in this dataset had very similar Prnl and Prn2 scores since they clustered in a small group close to the bottom of the added solid line. A subset of samples can be seen associated with this line, similarly to what is observed with the other datasets depicted in Panels (A), (B), and (C).
  • the characteristic profile for Cannabis Flower samples is overlaid on a 2 dimensional color array, where the horizontal dimension is the Hue (H) color value parameter, and the vertical dimension is the Saturation (S) color value parameter.
  • the 3 rd color value parameter namely the Luminosity (L) color value parameter of the HSL color space is not used.
  • the Hue varies horizontally from a Violet / Purple on the left side through all the spectral colors ending with red on the right. The color varies from saturated and bright vibrant colors at the top of the array to a series of differently shaded greys at the bottom of the array.

  • the colors assigned by this embodiment of the Color Mapping Algorithm vary slightly from a grey -green for Flower samples harvested from the bottom positions on branches to a slightly brighter shade of green for Flower samples harvested from the top positions on branches. This slight change in assigned output color would be a function of slightly differing terpenoid profiles in bottom Flowers vs top Flowers. This would be an entirely expected outcome of the application of this method.
  • Figure 148 is similar to Figure 146, except that another subset of Cannabis Flower data is presented.
  • the Cannabis Flowers are from an "OG" strain.
  • the samples originate from Flowers that were produced from plants that were either grown outdoors or in a greenhouse.
  • a subset of these Flowers was either subjected to hand trimming or left untrimmed.
  • the output color varies from green for samples such as 2-i-O-C-T-u to a greenish-brown for samples such as 2-P-O-C-T-t and 2-P-O-C-T-u. There is a very slight difference between these samples with the untrimmed sample showing a bit more brown compared to the slightly greenish brown of the trimmed sample.
  • Figure 150 depicts the color output result for the "Tangie" Strain.
  • the color output ranges are more in the blue-grey to blue-green range.
  • the samples from Flowers harvested from bottom positions on the branch show a more grey -blue color compared to those harvested from positions on the top of the branches which show a more grey-green color. This data demonstrates that there are subtle but consistent differences in terpenoid profiles based on Flower position on the branch.
  • this embodiment of the Color Mapping Algorithm uses Principal Component Analysis (PCA) to derive Prnl and Prn2 Scores respectively for each sample based on their individual terpenoid content, These scores are assiigned Hue (H) and Saturation (S) color value parameters of HSL color space. As shown in this embodiment, this is a 2 dimensional mapping approach. This contrasts with the method of the First embodiment that uses a 3 dimensional approach.
  • PCA Principal Component Analysis
  • the specific terpenoid concentrations are designed so that their derived Prnl and Prn2 Scores when used in conjunction with the set of Cannabis Flower samples intended for analysis, would place them towards the extremes of the Prnl and Prn2 scores observed for the type of commodity, such as Cannabis, which is being measured in this way.
  • the use of such internal standards may help to provide both a Quality Assurance function as well as a way to normalize the Prnl and Prn2 Scores for samples analyzed at different times.
  • the use of such quality control standards should permit some fine tuning of the data should that be needed to permit absolute comparison between datasets.

  • the sample designated as #46 is assigned as a reference standard. All Euclidean Distances are evaluated relative to this reference standard.
  • a color assignment or mapping algorithm can then easily assign a color to that singe distance value for each sample. There are many color assignment algorithms that may be used in this case. Such procedures are very often a part of graphing software programs that can assign a series of colors to a set of continuous variables. In the example of Figure 154, a Spectral theme of Color Mapping was applied.
  • the reference sample stands out as blue, since its difference from itself is 0 and is the minimum value.
  • the other samples show varying color depending upon the magnitude of their Euclidean Distances from this reference standard.
  • this 1 Dimensional Color Mapping of Euclidean Distance values derived from HCA may be considered as less resolving in terms of assigned color in comparison to the PCA - HS(L) or the 3 Key Terpenoid - RGB embodiments.
  • this 1 Dimensional Euclidean Distance mapping embodiment is useful when there is a need to compare a set of samples within a single dataset. This embodiment would therefore find utility if it were desired to evaluate and indicate on a package label how similar or different the elements within a collection of a particular commodity, such as a set of spices, herbs, or Cannabis might be relative to each other. This information could be communicated to customers and the like by appropriately printing a colored symbol on the package label.
