基于PCR-RFLP的西洋参和人参指纹特征鉴定
Fingerprint Dentification of Panax Quinquefolius and Panax ginseng Based on PCR-RFLP
摘要
Abstract
Objective To establish DNA PCR-RFLP method for the identification of Panax quinquefolius and Panax ginseng. Method The modified CTAB method was used to extract genome DNA from Panax quinquefolius and Panax ginseng. Specific primers were designed with bioinformatics software of ribosomal DNA ITS sequences for Panax quinquefolius and Panax ginseng. The specified sequence was amplified by PCR technology,and the enzyme products obtained by the method of RFLP were identified and compared for fingerprint. Results DNA 19 kb genome fragments were obtained from Panax quinquefolius and Panax ginseng. The 122 bp size of the ribosomal gene fragment was amplified. After enzyme digestion,Panax quinquefolius had two fragments of 80 bp and 42 bp,while Panax ginseng had only a single fragment of 122 bp. Conclusion Both the DNA fingerprints of Panax quinquefolius and Panax ginseng had specific enzyme site which could be used as an effective method for identification. The experimental results showed that the method was simple,rapid and reliable.关键词
