UPLC method has been developed in recent
years for pharmaceutical analysis but not yet
utilized in quality control analysis of pharma-
ceutical formulations. Although applications
of UPLC have been reported in the past years,

has the potential for more pioneering research
(29). Although this method separated about 30
peaks, but were unable to characterize all
peaks due to lack of standard substances.
UPLC separation identified some phenolic
compounds especially flavonoids such as
