本文采取正辛醇 -水分配体系模拟水仙根、茎、叶的水煎液中锌、锰、镁、钙、锡、铁、铜、铬、镉、铅在人体胃肠中的分配情况 ,应用原子吸收光谱法测定了水仙三个部位上述 10种微量元素的总含量 ,以及水煎液中各微量元素水溶态、醇溶态含量 ,探讨了酸度对水煎液中微量元素形态的影响 ,实验结果表明 ,水仙中微量元素的溶出率 ,微量元素的形态分布与水仙各部位成分及作用靶位 (胃、肠 )的酸度有关 In this paper, n-octanol-water distribution system is used to simulate the distribution of zinc, manganese, magnesium, calcium, tin, iron, copper, chromium, cadmium and lead in human gastrointestinal tract in decoction of root, stem and leaf of narcissus. Atomic Absorption Spectrometry was used to determine the total content of the above 10 trace elements in the three parts of Narcissus and the water-soluble and alcohol-soluble contents of trace elements in the decoction. The effects of acidity on the trace elements in decoction were also discussed. The results showed that the dissolution rate of trace elements in narcissus, the distribution of trace elements and Narcissus and the role of each part of the target site (stomach, intestine) acidity
