摘　　要：分别对万寿菊花瓣、种子、地上(除去花瓣和种子)及地下部分的微量元素、单宁、黄酮含量及pH值进行了测定,并分析了其相关性。结果显示:种子中各微量元素的含量均较高;不同部位中微量元素Zn的含量最高;花瓣中的单宁含量和黄酮含量最高,但pH值最小;As与Pb显著相关,As、Pb与黄酮含量显著相关。The contents of trace elements, tannin, flavonoids and pH value of petals, seeds, aerial part removing the petals and seeds, and the underground part of marigold were determined and the correlation were analyzed. The results showed.the content of Zn in different parts was the highest; the content of each trace element in seeds was the highest ; the contents of tannin and flavonoids in petals were the highest,but its pH value were the lowest ;the content correlations of As with Pb,flavonoids with As or Pb were significant.
