Determination of Total Flavonoids,Total Polyphenols,Total Polysaccharides and Total Saponins in Cistanche deserticola Formula Tea by Ultraviolet-Visible Spectrophotometry
Objective:To detect the contents of total flavonoids,total polyphenols,total polysaccharides and total saponins in Cistanche deserticola formula tea,so as to provide experimental basis for the quality control of tea and the basic research of anti-fatigue substances.Method:The contents of total flavonoids,total polyphenols,total polysaccharides and total saponins in Cistanche deserticola formula tea were determined by ultraviolet-visible spectrophotometry(UV-Vis).Result:The contents of total flavonoids,total polyphenols,total polysaccharides and total saponins in Cistanche deserticola formula tea were 8.23%~8.75%,9.30%~9.67%,1.20%~1.58% and 1.87%~2.86%,respectively.Conclusion:The main components of Cistanche deserticola formula tea are flavonoids and polyphenols,and the contents of saponins and polysaccharides are relatively low.
