Abstract

OBJECTIVE:To determine the contents of Total flavonoids and metal elements in Scutellaria baicalensis Georgi and to study the function of the microelements in treating cerebrovascular diseases.METHODS:The contents of macroelements(Na,Ca,Mg,and K)and microelements(Fe,Mn,Cu,and Zn)were determined by atomic absorpt ion spectropho- tometry(AAS);the Total flavonoids in Scutellaria baicalensis Georgi were extracted by alcohol extraction method,and the content of Scutellaria baicalensis Georgi was determined by UV spectrophotometry.RESULTS:The results showed that metal elements and Flavonoids were rich in Scutellaria baicalensis Georgi.CONCLUSION:The determination results provide scientific basis for the reasonable use of Scutellaria baicalensis Georgi to eliminate free radicals,prevent and treat cerebrovas- cular diseases as well as data for the wide exploitation and use of Scutellaria baicalensis Georgi.
