Abstract
The fluorometric method of Ogawa for vitamin C was compared with the colorimetric method of Roe in the modification of Teruuchi et al. using 13 varieties of vegetable tissues as well as 16 varieties of animal ones. The vitamin C values found with vegetable tissues were similar, but those for animal tissues differed markedly between the two methods. In the latter, the fluorometric values was much higher than the colorimetric ones. The specificity of the fluorometric method may therefore be considered to be inferior to the colorimetric, at least with animal tissues.
