To establish the preparation technique of the certified reference material of dihydrocapsaicin. Dihydrocapsaicin was prepared by Pd/C catalytic hydrogenation of capsaicin extract and recrystallization. Its chemical structure was identified by UV, IR, MS and NMR. The homogeneity and stability were systematic checked. A cooperative certification was conducted with 8 qualified laboratories. The results showed that the certified value of the reference material of dihydrocapsaicin was 99.30 % with the expanded uncertainty of 0.32 % in confidence coefficient of 95 %. The reference material of dihydrocapsaicin can conform to the technical requirement of the certified reference material. The materials were intended for use in the method validation and quality control of regarding products.
