Cannabinoids, the main constituents of the cannabis plant, are being increasingly studied for their medicinal properties. Cannabinolic acid (CBNA; 1) was synthesized from tetrahydrocannabinolic acid (THCA; 2), a major constituent of the cannabis plant, by aromatization using selenium dioxide mixed with trimethylsilyl polyphosphate as catalyst in chloroform. Purification was achieved by centrifugal partition chromatography, and the final product had a purity of over 96 % by GC analysis. Spectroscopic data on CBNA such as 1H-NMR and IR, and molar extinction coefficients, as well as chromatographic data are presented as useful references for further research on CBNA. The developed method allows production of CBNA on a preparative scale, making it available for further studies on its biological activities as well as use as a reference standard for analytical procedures.
大麻素是大麻植物的主要成分,人们正越来越多地研究其药用特性。大麻酚酸(CBNA;1)是以大麻植物的主要成分四氢大麻酚酸(THCA;2)为原料,在氯仿中使用二氧化硒与三甲基硅基多磷酸酯混合作为催化剂,通过芳香化作用合成的。通过离心分离色谱法进行纯化,经气相色谱分析,最终产品的纯度超过 96%。文中提供了 CBNA 的光谱数据(如 1H-NMR 和 IR)、摩尔消光系数以及色谱数据,为进一步研究 CBNA 提供了有用的参考。所开发的方法可用于制备规模的 CBNA,使其可用于进一步研究其生物活性,并可用作分析程序的参考标准。
