The assay of determination of total sugar content in Lactarius deliciosus (L. ex Fr. ) Gray was built. By phenol-sulfuric method, determination wavelength, precision, accuracy and stability were discussed. The results showed that the measure wavelength was 490 nm, the total sugar content of Lactarius deliciosus ( L. ex Fr. ) Gray was an average of 56.0μg/mL, RSD was 0.47% and the average recovery was 99.1%. This method provided a quick and convenient technique for the determination of total sugar content in Lactarius deliciosus (L. ex Fr. ) Gray.
