Six acidic metabolites were isolated from rat faeces and identified by gas chromatographymass spectrometry and proton magnetic resonance. Cannabinol-7-oic acid was the most abundant acidic metabolite isolated. Others present in decreasing order of prominence were 1"-hydroxy-, 4"-hydroxy-, 3"-hydroxycannabinol-7-oic acid, cannabinol-3"-one-7-oic acid and 2"-hydroxycannabinol-7-oic acid.
