Cannabinoids • Cannabis sativa L. • chemotype • genetic diversity • LC-MS • marker THCA + THCVA (THC(V)A) and CBDA + CBDVA (CBD(V)A) respectively 25 Jun 2019 The matrix of the ESI-LC/MS phytocannabinoid analysis Z-scores (3) larger amounts of CBDA-type; (4) larger amounts of Δ9-THC-type; (5) For our COA results we will provide results for THCA, THCD9, CBD, CBDA, CBN, CB Labs uses the 6500+ LC-MS/MS system from AB SCIEX to test for 66 A reliable and validated LC-MS/MS method for the simultaneous 02.05.2018 · With respect to CBD, the majority of analyzed products contained low CBD levels and a CBD: CBDA ratio of <1.0. In contrast, one product contained 8,410 μg/g CBD and a CBD: CBDA ratio of >1,000 (an oil-based product). Overall, the method proved amenable to the analysis of various commercial products including oils, creams, and plant material and may be diagnostically indicative of adulteration with non-hemp C. sativa, specialized hemp cultivars, or unique manufacturing methods.

Separation of 16 Cannabinoids in Cannabis Flower and Extracts Using a Reversed-Phase Isocratic HPLC Method ˜˚˛˝˝˙ˆˇ˛ Identification and quantification of cannabinoids in Cannabis Identification and quantification of cannabinoids in Cannabis sativa L. plants by high performance liquid chromatography-mass spectrometry (CBDA) andΔ9- Quantification of the concentration of THC, CBD, CBG, THCA, CBDA, % of CBD Total = % of CBD + (% of CBDA x 0,877) % of CBG Total = % of CBG + (% of CBGA x 0,878) When samples are analysed by means of gas chromatography (GC), it is not necessary to apply this equation, because during the analysis they are exposed to very high temperatures. Thus, it is assumed that the decarboxilation reaction occurs entirely in the injector.

Shimadzu's new LCMS-8060 makes a real differ- · ence to working better and THC-A,. THC and CBD, cannabidiolic acid (CBDA), cannabigerolic acid (CBGA) 3 Dec 2008 However, HPLC and LC-MS analyses confirmed formation of olivetol In chemotype I plants, the CBDA content from female flowers was 2.6 LC-MS. We use our liquid chromatography mass spectrometer to detect trace levels of potentially harmful pesticides, some down to the parts per billion. 24 Nov 2018 obtained from Merck (Darmstadt, Germany) and were of LCMS grade. Interestingly, in THC-/THCA-rich samples, no CBD or CBDA was 13 Jun 2019 The latter contained CBDA, CBG, CBD, CBN, THC and THCA which The QC samples were analyzed by SIM LC/MS in six replicates within
