Regulatory sampling of industrial hemp plant samples (Cannabis sativa L.) using UPLC-MS/MS method for detection and quantification of twelve cannabinoids

Table 6 Statistical analysis of CBC, total CBD, total CBG, and total THC in flower versus composite samples

Cannabinoid	Sample type		Mean difference	Intraclass correlation coefficient
Cannabinoid	Flower (% w/w)	Composite (% w/w)	Mean difference	Intraclass correlation coefficient
CBC	0.27 ± 0.19	0.25 ± 0.19	0.02	0.79
Total CBD	12.3 ± 2.51	11.0 ± 1.98	1.32*	0.32
Total CBG	0.28 ± 0.11	0.25 ± 0.11	0.03	0.55
Total THC	0.69 ± 0.16	0.60 ± 0.13	0.09*	0.29

Values represent the mean ± standard deviation. A two-tailed paired t test was performed to determine if there was a significant mean difference between the composite and flower only samples. *indicates a significant difference at p ≤ 0.05. Intraclass correlation coefficient was also calculated for each group to determine the degree to which values from the same group agree. This coefficient is interpreted as follows: <0.5 poor agreement, 0.5–0.75 moderate agreement, 0.75–0.9 good agreement, and >0.9 excellent agreement
