Abstract
A method for controlling the quality of traditional Chinese patent medicines is based on metagenomics. The method includes extracting genomic DNA of a sample of the traditional Chinese patent medicine, constructing a library of the genomic DNA based on a high-throughput sequencing platform, and performing metagenomic sequencing. The data obtained from the metagenomic sequencing is processed to obtain the ITS2 sequence of the traditional Chinese patent medicine sample A BLAST alignment is performed on the ITS2 sequence in the DNA Barcoding System for Identifying Herbal Medicine, to obtain species identification results. The obtained identification results are compared with the labeled species of the traditional Chinese patent medicine to obtain a conclusion about the quality of the traditional Chinese patent medicine sample.
