Fig. 2
Concentration of major phytocannabinoids in pre-packaged ground Cannabis inflorescence stored at 5°C. The middle circle represents the mean value of several duplicates and the upper and lower lines represent the upper and lower 95% confidence interval values. BL, baseline; M, month; CBDA, cannabidiol acid; THC, (-)-∆9-trans- tetrahydrocannabinol; THCA, (-)-∆9-trans- tetrahydrocannabinol acid; CBGA, cannabigerolic acid; CBN, cannabinol; “Total” represents the sum of the acid and neutral components. Statistically significant differences between times of storage were calculated by one-way ANOVA, utilizing Fisher’s exact test analyses (whenever significant, stated as the p value and when not significant stated as N.S.), followed by a Tukey post hoc multiple comparison test (*, p<0.05; **, p<0.01; ***, p<0.001)
