| Abstract: | Using D-xylose as standard and DNS as color developing reagent, the content of xylose in coconut shell was indirectly determined by spectrophotometry. The results showed that the maximum absorption wavelength is 490 nm with the good recurrences, and high recovery, and the relative error is small. This method is simple in operation with good result. |
