Abstract
This study aims to verify the accuracy of the UPLC-MS method for analyzing Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) levels. The contents were investigated in hemp seeds, hemp seed oil, and processed foods containing hemp seeds in South Korea. Our results confirmed that the method was appropriate with high selectivity, reproducibility, linearity, and recovery for both THC (94.1∼108.3%) and CBD (84.9∼109.0%). It was determined that 13 out of the 16 tested products were within the suitable range of THC and CBD levels. However, three out of nine hemp seed oil products exceeded the standards for these compounds, indicating the need for continuous monitoring. The results of our study verify and conclude the reliability of LC-MS/MS as a method for determining THC and CBD concentrations in hemp seeds and hemp seed oil.
