Complete Chloroplast Genome Analysis of Two Important Medicinal Species: and .

Most species are valued as foods, ornamental plants, or plants with medicinal properties. However, morphological characteristics and commonly used DNA barcode fragments are not sufficient for accurately identifying species. Difficulties in species identification have led to confusion in the sale and use of for medicinal use.

Identification of medicinal plants within the Apocynaceae family using ITS2 and psbA-trnH barcodes.

To ensure the safety of medications, it is vital to accurately authenticate species of the Apocynaceae family, which is rich in poisonous medicinal plants. We identified Apocynaceae species by using nuclear internal transcribed spacer 2 (ITS2) and psbA-trnH based on experimental data. The identification ability of ITS2 and psbA-trnH was assessed using specific genetic divergence, BLAST1, and neighbor-joining trees.

[Study on macroscopic and microscopic identification of Saposhnikovia divaricata and its counterfeits].

Objective: To provide an identification method for the roots of Saposhnikovia divaricata and its three counterfeits.

Methods: Macroscopic identification and microscopic identification of root transverse section and powder were carried out to distinguish these four species.

Results: For macroscopic characteristics, Saposhnikoviae Radix and its counterfeits can be distinguished by the head of the residual leaf and sections.
