Abstract
針對植育於霧峰農試所之臺灣地區主要食用之六類（包含22種品系）山藥之礦物質，藉最適化儀器中子活化分析(INAA)，進行必須及微量元素分析。本文對每山藥品系進行三重複量測，共分析19種元素。INAA方法並與國際原子能總署地衣標準品(IAEA-336)進行比對/品質管制。結果顯示，大部份的礦物質含量於同種植地區相似，但在各品系中分佈範圍及差異性極大，台農1、2號具有最多的鉀、鎂及鐵；硒與砷是第一次分析於臺灣地區生產山藥，濃度在10-2至10-3 mg/kg之間。本結果與馬來西亞、斯里蘭卡等地山藥元素含量分佈相似。
Six distinct species of yam “Dioscorea spp.” (22 varieties) cultivated I wufeng in Taiwan and consumed by most Taiwanese, were analyzed using optimal instrumental neutron activation analsysis (INAA). The contents of 19 mineral elements were determined. Samples and standards were analyzed in triplicate. Standard reference material (SRM), IAEA-336 lichen, was also analyzed using concentration analysis and quality assurance analysis. Results indicated that TNG1 and TNG2 had the most K, Mg, and Fe. Most of the elements had wide concentration ranges among the different species. Selenium and Arsenic first analyzed were in Taiwanese Yam, ranging from 10-2 to 10-3 mg/kg. Results show good agreement with Dioscorea spp. planted in Malaysia and Sri Lanka.
