Hemp seeds and hempseed oil are marketed on- and off-line as health foods and cosmetics and have been reported to have high nutrient contents. However, because of the various side effects of cannabinoids, especially △ 9 -tetrahydrocannabinol (THC), many countries regulate upper limits for THC in products, which creates the need for analytical techniques capable of measuring THC, cannabidiol (CBD), and cannabinol (CBN) levels in commercial hemp seeds and hempseed oil. In the present study, hemp seed and hempseed oil extracts obtained by methanol extraction, were analyzed by gas chromatography-mass spectrometry (GC/MS). Validation of the technique used was performed using calibration curves and by determining LODs, LOQs, specificities, selectivities, and intra- and inter-day precision and accuracies. In addition, matrix effects, process efficiencies, recoveries, and sample stabilities were investigated. In hemp seeds, as determined using the fully optimized method THC concentrations ranged from 0.06 to 5.91 μg/g, CBD concentrations from 0.32 to 25.55 μg/g, and CBN concentrations from 0.01 to 1.50 μg/g; CBN/THC ratios ranged from 0.1 to 1.60, and CBD/THC ratios from 0.11 to 62.56. Furthermore, the (THC + CBN)/CBD ratio of most hemp seed samples was less than one. In hempseed oil, THC concentrations ranged from 0.3 to 19.73 μg/mL, CBD concentrations from 6.66 to 63.40 μg/mL, CBN concentrations from 0.11 to 2.31 μg/mL, CBN/THC ratios from 0.12 to 0.42, and CBD/THC ratios from 3.21 to 22.50. Furthermore, (THC + CBN)/CBD ratios in all hempseed oil samples were less than one. The optimized methanol extraction-GC/MS technique was found to be satisfactory for determining THC, CBD, and CBN concentrations in hemp seeds and hempseed oil.

South Korea had a long relationship with cannabis before it was banned. In ancient times, Koreans had many uses for the cannabis plant — they even have a deity that protected their cannabis fields.
Summary: Buying CBD in South Korea
In this crash course, we’ll bring you closer to the current rules on CBD in South Korea, and we’ll take a look at how you can obtain a permit to use medical CBD.
A Brief History of Cannabis Laws in South Korea
The only way to import CBD to South Korea is through the KODC.
For Korean startups, this is now the perfect time to plan to start a hemp oil or CBD oil business in Korea. This is because if history has anything to say, CBD products will soon be legalized for the general public in Korea. Those that plan early can reap the benefits.
The current state of CBD oil in Korea
The Ministry of Food and Drug Safety (MFDS) will create regulations regarding medical cannabis/CBD. This is because there are still some side effects associated with CBD. The FDA does not regulate the safety and purity of CBD in the United States. Therefore the Ministry of Food and Drug Safety needs to test them to make sure the product does not contain harmful elements or has any levels of THC.
The Potential CBD Market in Southeast Asia
Therefore during this time, it would be wise to set up a marketing campaign around the benefits of CBD. As the Korean public understands the benefits of CBD, the demand will come. This will also attract Korean investors to get the capital you need to start your CBD business in Korea. In addition, keep up to date on new developments as the Korean government moves forward with new regulations regarding CBD.
