摘要： Contents of eight mineral elements in maca (Lepidium meyenii Walp.) from China and Peru were determined by inductively coupled plasma optical emission spectroscopy. Cu contents in maca samples from China (2.5-31mg kg(-1) dry weight, dw) were higher than the samples from Peru (<2.1 mg kg(-1) dw). Na in two samples from China was found to be significantly of high content (2400 and 2600 mg kg(-1) dw). The contents (mg kg(-1) dw) of B, Co, Cr, Li, Ni, and Zn were, respectively, 8.1-21, < 0.023, < 1.1 similar to 3.5, 0.020-0.17, 0.085-4.5, and 10-39 for the samples from China, while being 6.6-12, < 0.023, < 1.1 similar to 2.3, 0.035-0.063, 0.68-1.7, and 27-39 for the samples from Peru.
