| Abstract: | Using glucose as standard and DNS as color developing reagent, the content of total reducing saccharide in Dioscorea alata Linn was determined by spectrophotometry. The results showed that the maximum absorption wavelength of sample extract is 470 nm. The method has the characteristics of good repeatability, high recovery rate and low relative error. |
