Abstract: Using glucose as standard and DNS as color developing reagent,the content of total reducing saccharide in banana root solid bulb was determined by spectrophotometry. The results showed that the maximum absorption wavelength of sample extract is 500 nm. The method has the characteristics of good repeatability,high recovery rate and low relative error.

Key words: banana root solid bulb, reducing saccharide, spectrophotometry
