✦ Synopsis

Contents of 24 mineral elements in different types of Jilin ginseng were determined for the first time by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The results indicate that the contents vary with ginseng type, location, and place of origin. The total amounts of the essential elements (\mathrm{Ca}, \mathrm{P}, \mathrm{Mg}, \mathrm{Fe}, \mathrm{Sr}, \mathrm{Mn}, \mathrm{Zn}, \mathrm{Cr}, \mathrm{Cu}, \mathrm{Ni}, \mathrm{V}, \mathrm{Co}), and Mo in the types of ginseng tested are in the following order: Changbe (>) Zhujielu (>) Damaya (>) Ermaya (>) Yuanlu. This agrees with the total contents of elements detected. The amount of harmful microelements such as (\mathrm{Pb}) and (\mathrm{Cd}) in all types of ginseng is far below the toxic dose. In this study, the relative error is (1.76-15.38 %), the precision is (0.3-11.0 %), the detection power is (0.00 X-X \times 10^{3} \mu \mathrm{g} / \mathrm{g}), and the standard recovery is (90-106 %). Thus a scientific foundation was provided for the optimum selection of superior types of ginseng. 01994 Academic Press. Inc.
