摘要：

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-mu-m 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.
