The Genetics Behind Cannabis Strains

To truly appreciate the importance of strain-specific extraction, we must first delve into cannabis’s intricate chemistry. Each strain is a complex tapestry of compounds, with major cannabinoids, terpenes, and minor cannabinoids all playing crucial roles.

Cannabis Genome Complexity

The cannabis genome is highly complex, with approximately 30,000 genes. Essential genes influence cannabinoid and terpene profiles, critical for the plant’s effects and flavors.

Essential Genes Influencing Cannabinoid and Terpene Profiles

• THCAS (Tetrahydrocannabinolic Acid Synthase): Enzyme responsible for producing THC (Δ9-tetrahydrocannabinol, C₂₁H₃₀O₂), the primary psychoactive compound.
• CBDAS (Cannabidiolic Acid Synthase): Enzyme responsible for producing CBD (cannabidiol, C₂₁H₃₀O₂), known for its therapeutic benefits.
• TPS (Terpene Synthase) Genes: Enzymes involved in the biosynthesis of terpenes like myrcene, limonene, and pinene.

Role of Environmental Factors in Strain Expression

Environmental conditions such as light, temperature, humidity, and soil composition significantly influence the expression of these genes, affecting the final cannabinoid and terpene profile of the cannabis plant.

Chemotypic Variations in Cannabis Strains

Chemotypic variation refers to the differences in chemical composition between cannabis strains, primarily focusing on cannabinoids, terpenes, and minor cannabinoids.

Major Cannabinoids and Their Ratios

• THC (Tetrahydrocannabinol): The primary psychoactive compound in cannabis. THC content can range from less than 0.3% in hemp to over 30% in high-potency strains.
• CBD (Cannabidiol): Non-psychoactive, known for its therapeutic benefits, anti-inflammatory and anxiolytic properties. CBD content varies widely, from trace amounts to over 20% in CBD-rich strains.
• CBG (Cannabigerol): Non-psychoactive precursor to other cannabinoids, showing promise in neuroprotection and anti-inflammatory applications.
• CBC (Cannabichromene): Non-psychoactive, with potential anti-inflammatory and anti-depressant properties.

The ratios of these cannabinoids significantly influence the effects of each strain. For example, a 1:1 THC:CBD ratio is often sought for balanced effects, while high-THC strains are preferred for more robust psychoactive experiences.

Extraction Techniques for Preserving Strain Specificity

Traditional Methods and Their Limitations

Traditional extraction methods include dry sieving, water/ice extraction, and simple solvent extraction. These methods are outdated and inferior compared to PURE5™ advanced extraction technology.

• Dry Sieving:
  • Method: Mechanically separating trichomes from the plant material using fine screens.
  • Limitations: This results in lower purity and yields when often mixed with plant particles. Delicate trichomes are often damaged, leading to significant losses in potency and terpene content.
• Water/Ice Extraction:
  • Method: Cold water and ice are utilized to break the trichomes from the plant material and limit the penetration of the plant matter.
  • Limitations: This is a time-consuming and labor-intensive process, resulting in a much higher processing cost. Ice water can only break part of the trichomes and further reduces the yield of minor cannabinoids and the strain’s unique profile while going through a sequential high-temperature press.
• Simple Solvent Extraction:
  • Method: The plant material is washed with aggressive solvents like DME, hexane, ethanol, or butane to extract cannabinoids and terpenes.
  • Limitations: Due to their high boiling points, solvent residues can remain if they are not adequately purged, causing additive oxidation and the occurrence of bi-products. High temperatures often used can degrade cannabinoids and terpenes, resulting in a less accurate strain profile.

Advanced Techniques (CO2, Ethanol, Hydrocarbon)

Modern extraction methods aim to improve efficiency and quality but still fall short of the superior preservation capabilities of PURE5™’s PBX extraction method.

• Supercritical CO2 Extraction:
  • Method: Sub- and supercritical CO2 (where CO2 behaves as both a liquid and gas) is used to extract cannabinoids and terpenes.
  • Limitations: Despite precise control, it operates at high temperatures and pressures, damaging terpenes (e.g., myrcene). It also leaves some residual solvents after the required ethanol co-solvent or post processing and is extremely expensive, requiring significant initial investment and high operational costs.
• Ethanol Extraction:
  • Method: Utilizes ethanol (C₂H₅OH) as a solvent to extract cannabinoids and terpenes.
  • Limitations: If not managed properly, ethanol can easily extract unwanted compounds like chlorophyll (C₅₅H₇₂MgN₄O₅), sugars, and mold and requires additional purification steps. High recovery temperatures can degrade sensitive compounds such as THC and CBD. This method is less selective and often less efficient. PURE5^TM has developed an improved ethanol extraction process with 4-stage terpene and solvent recovery to preserve the maximum content of those active compounds.
• Hydrocarbon Extraction:
  • Method: Uses hydrocarbons such as butane (C₄H₁₀) or propane (C₃H₈) to extract cannabinoids and terpenes.
  • Limitations: While it is somewhat efficient, it poses significant safety risks due to flammability. It requires meticulous purging to ensure no residual solvents remain, which is a complex and costly process. The high processing and facility costs and the vast safety concerns make this method less desirable than the PURE5™ PBX method.
