To develop a quantitative method for the determination of total flavonoids from different medicinal parts in Rosa davurica. Method: Using rutin as a standard substance
the content of total flavonoids in R. davurica was determined by spectrophotometer with absorption at 510 nm. Result: The linear range of rutin were 5~50 mg·L-1(r=0.999 8).The average recoveries(root
stem
fruit of Rosa Davurica) were 99.1%
99.5%
100.3%
with RSD of 1.86%
1.94%
1.57%. Conclusion: The method is simple
accurate and reliable.It can be used as a quality control method to determine the content of total flavonoids in different medicinal parts of R. davurica.
