Abstract

We compared with heavy metal concentration of herbal medicines in products of Gyeongbuk and the other area of Korea. The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Gyeongbuk area. The average levels of heavy metal of herbal medicines in Gyeongbuk area are as follows : Mercury is 0.037mg/kg, Chromium is 0.093mg/kg, Nickel is 0.108mg/kg, Copper is 0.475mg/kg, Zinc is 3.14mg/kg, Manganese is 1.52mg/kg, Iron is 7.83mg/kg, and Cadmium, Lead and Arsenic is not detected. It was very lower in concentrations than those of average Korea area. Therefore, Gyeongbuk area appear to be more proper to cultivated land than other area.. Minerals such as Ca and K were extracted more than Na and P in herbal medicines products of Gyeongbuk respectively. Minerals and heavy metal concentrations distributed in herbal medicines were analyzed. Little or no relationship was observed between minerals and heavy metals.
