Objective To determine the optimum extraction condition of total flavonoids from gossampinus malabaria leaf. Methods In this study,one-factor and orthogonal array design methods were used to optimize of total flavonoids from gossampinus malabaria leaf. The determination of total flavonoids was spectrometrical y carried out using quercetin as the reference standard. Results The optimal conditions for extracting total flavonoids from gossampinus malabaria leaf were 20 times the amount of ethanol, 80%ethanol as the extraction solvent, extraction time 1h, and 70 mesh crushed.The total flavonoids with the extraction process was 25.172mg/g. Conclusion The extraction method is simple, rliable, and accurate, which can be used as the optimum extraction conditions of total flavonoids from gossampinus malabaria leaf.
