Abstract
The contents of three forms of vitamin 132 (FAD, FMN and FR) in various tissues of several kinds of vegetables were measured.The FAD was found to represent the largest fraction in general tissues but in several tissues, which are very fibrous and declining their metabolism, (such as stems, petioles and roots of a few kinds of vegetables), the percentage of FAD was lower than FMN.The percentage of FR decreased in the tissues of winter vegetables, but increased in those of summer vegetables.
Two kinds of vegetable seeds were germinated and grown by sand culture, and the change of the three flawin fractions in a growing plant body was observed.In the seed.FMN took the largest part of flavins, but as it grows more mature, the content of FAD increased rapidly.
