Minor components of cannabis resin. VI. Mass spectrometric data and gas chromatographic retention times of components eluted after cannabinol.

Minor components of cannabis resin with longer retention times than that of cannabinol have been analyzed by use of a combined gas chromatograph-mass spectrometer-computer system. The presence of 30 such components has been detected. The data obtained indicate that some of the components are hydroxy derivatives of cannabinoids related to olivetol.
