✦ Synopsis

An optimized flow-mJectlon method IS described for the determmatlon of various cardiac glycosldes (lanatoslde A, B and C, dlgoxm, dlgltoxm, acetyldlgltoxm, ouabam) based on their reaction with plcnc acid m alkaline media usmg spectrophotometnc detection at 486 nm The cahbratron graph IS hnear for 0 025-O 5 g 1-l cardiac glycosldes (except ouabam) and 0 01-O 2 g 1-l ouabam, with R S D between 0 62 and 2 16% (n = 6) and a sample throughput of 60 h-' This method was utlhzed for the determination of dlgoxm m tablets and lanatoslde C and ouabam m mJectlons
