    【Abstract】 Objective To determine the saponins content of different Astragalus.Methods The saponins content of different Astragalus was determined by the method of ultraviolet spectrophotometry with the70%alcohol as the continuous reflux extrac-tion and with544nm as the detection wavelength.Results The saponins content of different Astragalus were0.336%in A.membranaceus(Fish.)Bge.Var.mongholicusBge.-Hsiao and0.118%in Astragalusmen-branaceus(Fisch).and0.314%in Astra-galusmen-Branaceus of natural.Conclusion The saponins content of Astragalus membranaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao is the highest.
