Abstract: To identify the commercial medicinal materials of Bombyx Batryticatus, two-dimensional DNA barcode was used to construct the "Internet Plus" identification system for Chinese medicine, which should benefit the cross-platform communication of DNA barcode information. Bombyx Batryticatus contained Bombyx mori Linnaeus and Beauveria bassiana (Bals.) Vuillant. Both COI and ITS sequences were obtained via PCR amplification for total genomic DNA extracted from raw materials using the animal genomic DNA kit, while only ITS but no COI sequences was obtained when using the plant genomic DNA kit. The ITS sequences obtained using the animal genomic DNA kit were consistent with those using plant genomic DNA kit. The medicinal materials yielded COI sequences and identified as B. mori. According to analysis of ITS sequences, the main species of the medicinal materials were identified as B. bassiana and few were identified as other fungi. NJ trees analysis based on ITS sequences suggests that it can be easily distinguished from other fungi. Our results showed that total genomic DNA of B. mori and B. bassiana was extracted simultaneously using the animal genomic DNA kit, which could effectively solve the problem in species identification of animal and fungi mixture materials. COI and ITS regions as DNA barcodes can stably and accurately identify Bombyx Batryticatus. The "Internet Plus" two-dimensional DNA barcode system will promote the standardization and normalization of Chinese medicinal materials market.
