以芥蓝为材料，采用分产品器官（叶片、叶柄、薹茎和花蕾）和整个产品器官匀浆两种取样方法，分别测定维生素C、可溶性糖、游离氨基酸和硝酸盐含量，并分析了其在产品器官中的分配和累积规律。结果表明，花蕾维生素C含量、游离氨基酸含量均最高，叶柄中最低；薹茎的可溶性糖含量最高，叶片最低；叶柄的硝酸盐含量最高，花蕾最低。产品器官中维生素C、可溶性糖、游离氨基酸均为分配至薹茎的比例最高，分别为48.02%、61.14%、49.73%，其次是叶片和叶柄，花蕾的分配比例最低；硝酸盐分配到薹茎的比例最高，达48.04%，其次为叶柄和叶片，分别为41.63%和10.02%，花蕾的分配比例最低。对菜薹整体匀浆法和分器官测定后加权求和的结果进行统计分析表明，两种测定方法无显著差异，在实际中可根据研究目的选用不同的测定方法。

With Chinese kale as material, we used two sampling methods, which were homogenizing each product organ (leaf, petiole, flower stalk and flower bud) respectively and homogenizing entire product organs together, and determined their contents of vitamin C, soluble sugar, free amino acids and nitrate content, in addition, analyzed their distribution and accumulation rules in product organs. The results showed that, the contents of vitamin C and free amino acids were highest in flower bud respectively, and were lowest in petiole. Soluble sugar content was highest in flower stalk and lowest in leaf. Nitrate content was highest in stem and lowest in flower bud. The flower stalk had the highest distribution ratios of vitamin C, soluble sugar and free amino acids, with the ratios of 47.06%, 61.14% and 49.73%, and the two product organs leaf and petiole took the second place, while the flower bud had the lowest distribution ratios. Nitrate was mainly allocated in flower stalk (48.04%), followed by petiole and leaf (41.63%and 10.02%), while the flower bud had the lowest distribution ratio. The results of statistical analysis showed that, there was no significant difference with the two methods, thus both the two sampling methods could be selected in the actual research according to different purpose.
