Distribution of volatile components and inorganic elements from Vernonia amygdalina / 中成药

ABSTRACT

AIM To investigate the distribution of volatile components and inorganic elements from Vernonia amygdalina Del..METHODS Volatile components and inorganic elements in different parts of V.amygdalina were analyzed and measured by HS-SPME-GC-MS and ICP-OES techniques.RESULTS Forty-four,sixty-seven,fifty-seven chemical compounds were identified from the root,stem and leaves of V.amygdalina,accounting for 83.9％,92.0％,83.9％ of the volatile components,respectively.Nineteen inorganic elements in total were detected,and the contents of As,Be,Bi,Co were too low to detect;The three inorganic elements with the highest content in root,stem and leaves were Mg,Al and Fe.CONCLUSION There are abundant volatile components and inorganic elements in V.amygdalina,with varying distribution in its different parts.
