Objective To establish a method for determining the content of total flavoes in fruit of Malus micromalus(MM). Method The content of total flavonoids in fruit of MM was determined at 500 nm by ultraviolet spectrophotometry with rutin as standard control.Results The standard curve of rutin was linear in the concentration range of 0.011 to 0.055 mg/ ml.The average recovery of total flaves was 100.35% with the relative standard deviation 1.3%(n=6).The content of total flavonoids in the samples was 0.276 0%.Con...
