Abstract

|
Germanium (Ge) content in Zingiberis Rhizoma was determined by flameless atomic absorption spectrometry with a graphite tube atomizer. The Ge content of the cortical layer was 65mcg/g, the central cylinder, 98mcg/g and the total, 87mcg/g. In the effect of the extraction of Ge by various solvents, polar solvent was more effective than the nonpolar one. Especially, water was the most effective solvent. The water extract of Zingiberis Rhizoma, separated by sephadex G-25 gel filtration, was fractionated into 2 peaks at 254nm. Both the peaks showed atomic absorptions of Ge. It may be concluded that the Ge components of Zingiberis Rhizoma exist as the form of an aqueous organic compounds or associated forms with proteins.
