Eleven reference compounds, namely, CBDA (1), CBGA (2), CBG (3), CBD (4), THCV ( 5), CBN ( 6), Δ 9 -THC ( 7), Δ 8 -THC (8), CBL (9) , CBC (10) , and THCAA (11) were isolated at the National Center for Natural Products Research (NCNPR), University of Mississippi, Mississippi, USA. The identity of standard compounds 1-11 were certified on the basis of the spectral data ( 1 H-and 13 C-NMR and HR-ESIMS). The purity was confirmed that all were above 95 % by chromatographic methods (data not shown). The stability of cannabinoids 1-11 was found to be stable in extraction solvents for up to 96 h. All tested samples were kept in a -20 °C freezer for up to 3 weeks with no changes observed.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
