Subcellular distributions of copper and lead in Herba Plantaginis
铜、铅在车前草中的亚细胞分配

We studied the subcellular distributions of Cu and Pb in leaves of Herba Plantagini taken from sites at Baobeidang(BBD) and Luxian(LX) in Sichuan Province. The results indicate that the biomass and the content of Cu and Pb were higher in H. Plantagini from BBD than that from LX. The levels of Cu and Pb in H. Plantagini from BBD were highest in the cytoplasmic organelles,less in the cell wall and lowest in the cytoplasmic supernatant. The levels of Cu and Pb in H. Plantagini from LX were highest in the cell ...
