Determination of the Contents of Metal Elements and Total Flavonoids in Flos Lonicerae Japonicae / 中国药房

ABSTRACT

OBJECTIVE:To establish methods for the determination of the metal elements and the Total flavonoids in Flos Lonicerae Japonicae.METHODS:The atomic absorption spectrometry was adopted to determine the contents of macroelements(Na,K,Ca,Mg)and trace elements(Cu,Zn,Fe,Mn,Cr,Ni)while UV spectrometry was adopted for the determination of the content of Total flavonoids in Flos Lonicerae Japonicae.RESULTS:Metal elements and Flavonoids were found to be rich in Flos Lonicerae Japonicae.CONCLUSION:The methods adopted in this study were simple,rapid,accurate,sensitive and precise.
