Analyses of ancient DNA (aDNA) from archaeological and historical skeletal material are characterized by low quality. Many soil contaminants such as humic acid, fulvic acid, and bone collagen are often co-extracted with aDNA and inhibit amplification by polymerase chain reaction (PCR). In this study, we compared with two methods of DNA extraction by phenolchloroform extraction and silica-bead extraction. In addition, we applied new protocol, ultra sonication based silica-bead extraction method to extract aDNA from some ancient human skeletal remains. This method was more effective by both mitochondrial DNA (mtDNA) and amelogenin gene amplification.
