title: [Study on hydrophobic constituents of Arnebia euchroma].
abstract: OBJECTIVE
  To investigate the massive hydrophobic constituents of Arnebia euchroma, and compare the similarities and differences of AE and AEZ from different sources.
  
  
  METHODS
  The hydrophobic constituents, AE01-1 and AEZ01-1, were obtained by the chromatograph of silica gel with elution of chloroform used in the chloroform extracts of Arnebia euchroma, AE01 and AEZ01. GC-MS was used to identify the main components of the hydrophobic constituents.
  
  
  RESULTS
  11 and 22 compounds were identified in the hydrophobic constituenty, AE01-1 and AEZ01-1, including 5 common compounds that were the main components. AE01-1, the hydrophobic constituents of AE, had 2 naphthoquinones, while AEZ01-1, the hydrophobic constituents of AEZ, had only lipid compounds.
  
  
  CONCLUSIONS
  Compared to the AE, AEZ has fewer naphthoquinones with low polarity.
