| Abstract: | Objective:To establish a method for the determination of water soluble proteins in Saigae Tataricae Cornu.Methods:The contents of water soluble proteins were determined through macerate extraction in low temperature water,with Bradford dying method,visible spectrophotometer.Water soluble proteins in Saigae Tataricae Cornu were extracted through maceration in low temperature water,and dyed by Bradford method,determined by visible spectrophotometer with the detection wavelength at 594nm.Results:There is a good linearity relation between the absorbency and the mass of standard proteins in the range of 21.6~108μg(r=0.9996).Conclusion:This method is suitable for the determination of water soluble proteins in Saigae Tataricae Cornu. |
