PROBLEM TO BE SOLVED: To provide qualitative and quantitative analyzing methods enhanced in reliability with respect to a water soluble compound having a sugar skeleton in a surfactant-containing sample wherein the presence of the water soluble compound having the sugar skeleton is estimated. SOLUTION: The qualitative analyzing method has a process (1) for mixing the surfactant-containing sample with a mixed liquid of heavy water and a strong acid or a heavy strong acid, a process (2) for hydrolyzing the water soluble compound having the sugar skeleton in the mixture obtained in the process (1) and a process (3) for measuring the mixture passing through the process by an H-NMR method. The quantitative analyzing method for the water soluble compound having the sugar skeleton in the surfactant-containing sample wherein the presence of the water soluble compound having the sugar skeleton is estimated has a process (1) for mixing the surfactant-containing sample with the mixed liquid of heavy water and the strong acid or the heavy strong acid, a process (2) for hydrolyzing the water soluble compound having the sugar skeleton in the mixture obtained in the process (1), a process (3) for adding an internal standard substance before or after the process (3) and a process (4) for measuring the mixture passing through the process (2) and containing the internal standard substance by the H-NMR method.
