Dna extraction from different specimens is the foundation of conservation genetics . it is difficult to extract total dna from tannage of chinese alligator with usual method 利用不同的实验材料提取适合研究的dna是保护遗传学研究的基础，而对于鞣制皮革，用常规的dna提取方法很难提到适合于研究的dna样品。

The results showed that dna of tannage could be extracted by this method and used as samples in conservation genetics . it is a good idea for molecular identification of leather things and amplification or sequencing of genes 结果证明，运用这种改进的提取方法从鞣制皮革中提取的总dna适合保护遗传学研究的需要，可用于部分序列的扩增和测序研究及扬子鳄皮质用品等的分子鉴定。

In this paper , total dna from tannage , tail skin , scales and the skin treated with salt were successfully extracted with an improved method for dna extraction . to verify the results , four pairs of primers , which were universal primers for 12s rrna gene , diagnostic primers of chinese alligator meat , microsatellite primers and rapd primer , were used to do pcr amplifications . some amplified fragments were sequenced , either 本文研究出一种改进的dna提取方法，成功地从扬子鳄鞣制皮革中提取了总dna ，同时对不同的组织标本如鳞片、盐腌生皮及尾尖皮等进行了dna提取：并利用12srrna基因扩增的通用引物、扬子鳄鉴定性引物、微卫星引物及rapd引物进行pcr扩增，且对部分pcr扩增结果进行测序，以检验提取效果。
