| Abstract: | The content of eight trace elements in Perilla's root, stem, leave were dertermined by fire atomic absorption spectrometry, and the best analysis conditions of the elements wer worked out by experiments. The recovery of each element is in the range from 96% to 105%. The relative standard deriation is no more than 6%. The method is sensitive, precise, practical. At the same the, the perilla's medical use was studied. |
