Comparison of Mineral Element Content in a Functional Food Maca (Lepidium meyenii Walp.) from Asia and South America.
Abstract
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 (2.5-31 mg 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, <1.1~3.5, 0.020-0.17, 0.085-4.5, and 10-39 for the
samples from China, while being 6.6-12, <0.023, <1.1~2.3,
0.035-0.063, 0.68-1.7, and 27-39 for the samples from Peru.
