- 論文の詳細を見る
A simple colorimetric method for the determination of cannabinoids was developed, using Fast Blue BB salt. Fast Blue BB salt produced stable diazo compounds with cannabinoids in alkaline media. The absorption maxima of Δ^8-tetrahydrocannabinol, Δ^9-tetrahydrocannabinol, cannabidiol and cannabinol were at 488,489,470 and 490 nm, respectively. The molar extinction coefficients of the above cannabinoids were estimated to be 3.3,2.9,5.2 and 2.5×10^4,respectively, and the coefficients of variation (10 analyses) were 0.7,0.4,0.4 and 2.7 (%), respectively. The contents of these cannabinoids in extracts from six kinds of cannabis leaves were determined by the colorimetric method in combination with thin-layer chromatography. The results obtained were in good agreement with those obtained by the gas chromatographic method.
