02.05.2018 · While THC and CBD are the most relevant cannabinoids to mammalian biology, C. sativa produces both in their inactive acidic forms [17,18]. The acidic forms of CBD and THC are cannabidiolic acid (CBDA) and Δ 9-tetrahydrocannabinolic acid A (THCA-A), respectively. Pure THC and CBD Extractions, Using CO2 and Chromatography | Pure THC and CBD Extractions, Using CO2 and Chromatography How do you produce pure Δ9 THC? A fellow named Adam Mueller answered this question, including the sub/supercritical conditions to produce pure Δ9 THC, and was issued a patent for it in 2014. CBD Analysis - CWCLabs.com Difficulty separating CBD from THC (because they are isobaric molecules), or difficulty separating CBD from CBG during chromatography (peaks often co-elute). Very low column life at the HPLC, resulting in high laboratory waste. No ability to detect counterfeit molecules that might co-elute with targeted analytes. Cannabis Analysis by HPLC | SIELC
