FIGURE 8.

Comparison of full phytocannabinoid (CNB) profiles of Type I and III Cannabis extracts after 1 year of storage at 4 and 25°C in DMSO, ethanol, or olive oil. Phytocannabinoids were identified and quantified by ESI-LC/MS at the initial time and after 12 months of storage (t₀ and t₁₂, respectively). Phytocannabinoids are arranged according to biosynthesis (A,G for Type I and III chemovars, respectively) and degradation products (B–F,H–L for Type I and III chemovars, respectively). Red and blue arrows indicate decarboxylation and aging pathways, respectively. Data are reported as mean phytocannabinoid concentrations (n = 3, %w/w). Absolute concentrations were color coded relative to the maximum value for each compound according to storage conditions. Supplementary Tables S12–S14, S15–S17 summarize the statistical significant differences for the effect of time, temperature, and solvent for Type I and III extracts, respectively.
