  1. aRatio of content was calculated based on ion peaks area of MCG root to that of FCG root. The ratio numbers colored in green and red represented the compound was higher-accumulated in FCG and MCG roots, respectively
  2. bLetters ‘F’ and ‘M’ indicate those compounds detected only in FCG and MCG, respectively
