Abstract
A simple method using ion-pair high-performance liquid chromatography was established for the rapid and precise determination of nokiol(3',5 'di-2-propenyl-1,1'-biphenyl-2,4'-diol) and gnolol(5,5'-di-2-propenyl- 1,1'-biphenyl-2,2'-diol) in eighteen species of oriental pharmaceutica l decoctions containing Magnolia bark. An ODS column and a mixed solve nt system of water involving 10 mm tetra-n-amylammonium bromide (TAA) and acetonitorile (4 : 6) as a mobil phase were used for the separatio n. Honokiol and magnolol were eluted without interference of other co- existing components within 12 min.
