Concentrations of major minerals(Ca, p, Na, K, Mg) and trace elements (Fe, Zn) were measured in human milk samples collected from 19 selected, healthy lactating women at 2~5 days, and at 4, 8 and 12 weeks postpartum. Decreases in the contents of m) or minerals and trace elements were found with the increase of time postpartum. Mean Ca contents of 2~5 days, 4 week, 8 week and 12 week in human milk were 243.02$\pm$50.90ug/ml, 295.0$\pm$65.70ug/ml, 295.0$\pm$41.50ug/ml, 349.90$\pm$83.50ug/ml, respectively And mean P contents of 2~5 days, 4 week, 8 week and 12 week in human milk were 134.70$\pm$49.4ug/ml, 134.90$\pm$19.70ug/ml, 117.60$\pm$18.90ug/ml, 130.60$\pm$28.20ug/ml, respectively. Ca/P of them were 1.81, 2.19, 2.20, 2.68, respectively. Mean Mg contents of them were 22.30$\pm$5.60ug/ml, 25.70$\pm$3.70ug/ml, 25.10$\pm$3.60ug/ml, 32.10$\pm$4.50ug/ml, respectively. And mean Na contents of them were 171.20$\pm$90.50ug/ml, 158.70$\pm$47.00ug/ml, 104.50$\pm$24.70ug/ml, 115.90$\pm$12.50ug/ml, respectively. Mean K contents of them were 506.10$\pm$156.10ug/ml, 520.90$\pm$55.00ug/ml, 370.10$\pm$29.00ug/ml, 468.40$\pm$75.70ug/ml, respectively. Na/K of them were 0.34, 0.30, 0.28, 0.25, respectively. Mean Fe contents of them were 2.80$\pm$1.80ug/ml, 2.70$\pm$0.40ug/ml, 2.60$\pm$0.40ug/ml, 2.10$\pm$0.10ug/ml, respectively. And mean Zn contents of them were 3.70$\pm$1.60ug/ml, 2.78$\pm$9.70ug/ml, 2.70$\pm$0.70ug/ml, 2.30$\pm$0.20ug/ml, respectively, These determinations will provide the basic information on the variability of major minerals and trace elements as lactation proceeds and on the composition of components between term and preterm milk.
