title: Identification and determination of 8 alpha, 9 alpha-epoxyhexahydrocannabinol as a metabolite of delta 8-tetrahydrocannabinol of mice in vitro.
abstract: 1. 8 alpha, 9 alpha-Epoxyhexahydrocannabinol (8 alpha, 9 alpha-EHHC) was formed from delta 8-tetrahydrocannabinol (delta 8-THC) by mouse liver microsomal preparation in the presence of an NADPH-generating system. 2. The epoxide was identified by t.l.c., g.l.c. and g.l.c.-mass spectrometry and, together with 11-hydroxy-delta 8-THC (11-OH-delta 8-THC), was determined by g.l.c. 3. When delta 8-THC was incubated with mouse liver microsomal preparation, 8 alpha, 9 alpha-EHHC and 11-OH-delta 8-THC was formed to the extents of 14% and 23%, respectively, of the added delta 8-THC.
