以菜心为材料，采用分产品器官(薹茎、叶片、叶柄、花蕾）和整个产品器官匀浆的方法，测定了维生素C、可溶性糖、游离氨基酸和硝酸盐含量，研究其分配和积累规律。试验结果表明，花蕾的维生素C、可溶性糖、游离氨基酸含量均最高，薹茎次之，叶柄与叶片较低；叶柄的硝酸盐含量最高，其他3种器官间差异不显著。从积累量看，薹茎和花蕾积累了79.8%的可溶性糖、70.3%的游离氨基酸和68.1%的维生素C，远高于其他器官积累量。硝酸盐主要积累在薹茎中，其次是叶柄和叶片，花蕾中最少。利用整个产品器官匀浆测定的维生素C、可溶性糖、游离氨基酸和硝酸盐含量计算的积累量，与分器官加权求和的方法获得的数值间差异不显著。

In the paper, we investigated the contents of vitamin C, soluble sugars, free amino acids and nitrate in different organ homogenates (bolting stem, leaf, petiole and flower bud) and in the entire plant homogenate of flowering Chinese cabbage ( L. ssp. ). The results showed that, flower bud had the highest contents of vitamin C, soluble sugar, free amino acids, and bolting stem took the second place. The nitrate content in petiole was significant higher than that in the other three organs, but nitrate content in the other three organs had no significant difference. There were 79.8% soluble sugar, 70.3% free amino acids and 68.1% vitamin C accumulated in bolting stem and flower bud, which were far higher than those in the other two organs. Nitrate was mostly accumulated in bolting stem, less in petiole and leaves, least in flower bud. While homogenized the entire plant organs together, the contents of vitamin C, soluble sugar, free amino acids and nitrate showed no significant difference with the weighted sums of the four different organs.
