A method is described for the quantitative analysis of 9-cis retinoic
acid in plasma. Following a simple extraction, the compounds are deter
mined by reversed-phase high-performance liquid chromatography (HPLC)
and detection at 350 nm.This method was applied to plasma specimens co
llected from rabbit which received by gorging a single dose administra
tion of this compound but it could be applied too to human plasma.
