Combining the techniques of thin-layer chromatography (TLC) and mass spectrometry, we unambiguously identified the trace metals Cu, Zn, Fe, Pb, Mn, Co, and Mg in the brain of a female human who had no evidence of any pathologic disease in the central nervous system, and in brains from mouse, rat, gu

β¦ Synopsis
Mn, Zn, Cu and Fe in total (TDF), soluble (SDF) and insoluble (IDF) dietary fiber residues of four different samples of peas were measured. The offical AOAC method was used to determine the TDF, SDF and IDF, and mineral content in the fiber residues was assayed by flame atomic absorption spectrophotometry. A considerable amount of ash was associated with TDF and SDF. The mineral association with TDF complex was considerable for Mn and Fe, moderate for Zn and negligible for Cu, although the mineral association differed as a function of dietary fiber fraction. A high percentage of Mn and Zn content in peas was associated with SDF, and Fe with IDF.

Samples from early Tertiary subbasaltic and interbasaltic profiles were extracted by using a selective dissolution procedure. The specificity of each extracting solution for the different adsorption components was examined and the most important phases for the dispersion of Fe, Mn, Cu, Zn, Ni, and A
