Determination of Total Flavonoids from Tartary Buckwheat

Objective To determine the content of total flavonoids from tartary buckwheat.Methods Spectrophotometry was adopted. Results At the wavelength of 420 nm,the total flavonoids content of instant tartary buckwheat was 6.87%.During the growth of tartary buckwheat sprouts,the total flavouoids content on the first,third,fifth and seventh day was respectively 3.31,4.19,4.20 and 4.15%.Conclusion The instant tartary buckwheat riches in flavonoids and has a broad development prospect.This method has the excellence of simple and convenient manipulation,so it suits the medium-sized and small-sized food processxng factories.
