The determination accuracy of flavonoids in larch using three kinds of spectrophotometry methods was compared on the basis of determination of dihydroquercetin in larch using HPLC.
Abstract : The purpose of this study was to determine the total flavonoids and dihydroquercetin contents in Picea asperata Mast. , and to further investigate its antioxidant activity.
Conclusion: Dihydroquercetin had an effective role to treat coronary heart disease by inhibiting myocardial tissue ischemia induced by ISO and protecting myocardial cells from injury.
