#$%^&*AU2020101758A420200917.pdf#####ABSTRACT The invention discloses a preparation method and application of total flavonoids extracted from leaves of Choerospondias Axillaris. Extract the leaves of Choerospondias Axillaris with ethanol, and extract and separate the extract with petroleum ether to obtain the total flavonoids of Choerospondias Axillaris Leaf; After ethyl acetate extraction and polyamide column purification, anthocyanins, flavones, flavonols, dihydroflavones, dihydroflavonols, chalcones, isoflavones, flavanols and other flavonoids are separated on silica thin-layer plate. The total flavonoids of Choerospondias Axillaris Leaf have obvious function of anti-arrhythmia, protecting myocardial ischemia, improving immune function, anti-oxidation, etc., and can be used to prepare drugs that can prevent and treat cardiovascular and cerebrovascular diseases, diseases with reduced immune function, and free radical damage diseases.-1150506 0 0.700 0530 400450.0 6600550. 0IM W L Waveleuth:A94.7 Abs:IJ. 0 1 Figure1I
