초록

국내에서 재배 수확되는 명일엽에 지역별, 부위별로 게르마늄 함량을 네모파 산화전극 벗김전압 전류법을 이용하여 조사한 결과 재배된 지역에 따라 게르마늄의 함량이 공시재료간 잎은 3.8배 정도, 줄기는 5배 정도였다. 명일옆(明日葉)의 채취부위별 게르마늄 함량은 잎부분에서 386ppm로 가장 높았으며 줄기에서 29ppm으로 13.3배 잎에서 더 높았다.

The uptake of germanium(Ge) by health foodstuffs was interesting because of a therapeutic effect of organic germanium. Germanium contents in different plant parts of the cultivated Korean Angelica keiskej Koidz in several growing districts were determined by square wave anodic stripping voltammetry. Experimental conditions in germanium determination from Angelica kejskej Koidz were as follows : deposition time; 20 sec, deposition potential; -0.9 volts vs Ag/AgCl, and frequency; 100 Hz in 0.1M HClO4, supporting electrolyte solution at pH 2.43 containing 1.5 × 105 M pyrocatechol violet. Calibration curve showed a good lineality in the range of 0.4 ppb to 2.0 ppm and the detection limit was 0.08 ppb. There was a large difference in content according to growing districts ranging from 102 to 386ppm. Germanium content in leaf parts was much higher than that in stems.
