Experimenal study Of Maxingshigan Valid Part flavonoids its Polysaccharides on anti-Influenza
Abstract:Objective  To establish the Method for Determination of Total Flavonoids in the Flavonoid Fraction of Maxingshigan dectoctin Antiviral Components. Methods  The content of total flavonoids was determined with Al2(NO3)3-NaOH-NaNO2 reaction development process,and selected rutin as reference substance. Results  The regression equation was as follows: Y=0.01417X-0.01763 (R2=0.99918);high précision preferably repeatability and stability. Conclusion  To determine content of flavonoids in rutin with ultraviolet spectrophotometry by standard Liquiritin is a practical method with higher accuracy.
Key words: Maxingshigan dectoctin; flavonoid; Al2(NO3)3-NaOH-NaNO2 reaction development process; ultraviolet spectrophotometry
