Determination of Germanium in Botanical Drugs by Flameless Atomic Absorption Spectrophotometry

흑연로 원자흡광분석법에 의한 생약중의 Germanium 함량에 관한 연구

Germanium in various botanical drugs was determined by flameless atomic absorption spectro-photometry with a graphite tube atomizer. The amounts of Ge in Zingiberis Rhizoma and Angelicae Radix were $169{\mu}g/g$ and $146{\mu}g/g$, respectively. The amounts of Ge in some other drugs ranged from $70{\mu}g/g$ to $130{\mu}g/g$. There is much more Ge in botanical drugs than in foods.
