| Abstract: | Objective To establish an HPLC method for determination of stachyose contents in Rehmannia Glutinosa Oligosaccharides(ROS).Methods Stachyose was determined with Rezex RPM-Monosaccharide Pb+ +8%(7.8 mm×300 mm)column, water as mobile phase and differential refractive index detector. Results The correlation coefficient between the area of stachyose and stachyose content was 0.999 5. The sample average recovery was 99.9%, the RSD was 1.2 %( n=6). Conclusion This method is simple, rapid, specific, accurate and reproducible. |
