Abstract: Objective To identify the status of Turki human remain and its relation to Khitan nobles by the means of molecular biology. Methods MtDNA was successfully extracted from Turki human remain. Through four overlapping primers, the nucleotide sequence of 360 bp length was gotten. Then it was contrasted with the cambridge reference sequence (CRS), and the sequence was analyzed with that of Khitan nobles basing the methods of phylogenetics. Results The result showed that Turki had closest relationship with Qidan noble individuals. And it was closer with Yeluyuzhi′s family in the two Qidan noble families. It was proved that Turki was the noble of Khitan. Besides, it showed that Turki had closest relationship with modern out Mongolia contrasted with the reported populations. And the 5 mutation sites of Turki were all hot mutation sites of Mongolian. Conclusion Turki is north Mongolian.
