PROBLEM TO BE SOLVED: To provide a method of quantitative determination the ratio of (1,6)-linked glucose/(1,3)-linked glucose inβ-glucan, capable of nondestructively measuring the ratio, in a relatively short time, without having to pretreat a measuring sample. SOLUTION: This method of determining quantitatively the ratio of (1,6)-linked glucose/(1,3)-linked glucose in theβ-glucan contained in the sample is a method of measuring a solid<SP>13</SP>C nuclear magnetic resonance spectrum of the sample, of calculating the integrated intensity ratio A/B of an integrated intensity A of C-1 carbon peak in the glucose, to the integrated intensity B of C-6 carbon peak in the (1,3)-linked glucose, based on a measured result, and of finding the ratio of (1,6)-linked glucose/(1,3)-coupled glucose, based on the calculated value.
