Abstract
Abstract A rapid method for the determination of polymethoxylated flavones present in Orthosiphon leaves is described. Sinensetin, tetramethylscutellarein and 3′-hydroxy-4′,5,6,7-tetramethoxyflavone were separated on a C18 3-μm Microsorb column using 2-propanol—tetrahydrofuran—water (22:4:74) as the eluent, followed by diode-array UV detection. The procedure was also applicable to the determination of polymethoxylated flavones from orange peel.
