title: [Identification of turtle shell, tortoise plastron and their counterfeit products].
abstract: OBJECTIVE
  To identify the commercial Chinese medicines turtle shell and tortoise plastron.
  
  
  METHODS
  Morphological identification and differential thermal analysis (DTA).
  
  
  RESULTS
  2 kinds of counterfeit turtle shell and 3 kinds of counterfeit tortoise plastron were found, and their morphological and DTA identification features were proposed.
  
  
  CONCLUSIONS
  Sea turtle shells presently on the market are sham commodities of turtle shell, which derive from Lissemys punctata and Pelochelys bibroni indigenous to south Asia, while plastrons of Ocadia sinensis, Chelonia mydas and Lepidochelys olivacea are counterfeit products of tortoise plastron. Turtle shells, tortoise plastrons and their counterfeit products may be exactly distinguished by morphological and DTA features.
