15-Lipoxygenase from soybeans is inactivated by bubbling air through enzyme solutions. This inactivation is prevented by flavonoids from the East Asian medicinal plant Orthosiphon spicatus, previously found to be inhibitors of the enzyme. 5,7,4'-Trimethylapigenin, eupatorin and 5,7,3',4'-tetramethylluteolin show the strongest

A simple liquid chromatographic method was developed for the simultaneous determination of flavonoids from Orthosiphon stamineus Benth, namely sinensitin, eupatorin and 3'-hydroxy-5,6,7,4'-tetramethoxyflavone, in plasma. Prior to analysis, the flavonoids and the internal standard (naproxen) were extracted from plasma samples using
