[Objective] The study aimed to provide the scientific basis for development and application of Alternanthera philoxeroides. [Method] Total flavonoids were extracted and qualitatively analyzed from Alternanthera philoxeroides under different conditions,with rutin as control,followed by quantitative analysis with UV spectrophotometry. [Result] The flavonoids content was reached 2.18% with 75% ethanol at 100 ℃; flavonoids content was reached 1.98% with 80% methanol at 100 ℃; flavonoids content was reached 1.99% with acetone at 100 ℃. [Conclusion] The best extraction condition was 75% ethanol at 100 ℃.
