Article Synopsis
  • Researchers developed a method to distinguish Astragali Radix from Hedysari Radix using PCR to amplify specific DNA alleles from 30 and 28 samples, respectively.
  • The study involved extracting DNA, amplifying specific sequences (trnL-trnF), and optimizing PCR conditions; results showed distinct band sizes for each plant – 136 bp for Astragali Radix and 323 bp for Hedysari Radix.
  • This technique effectively identifies and authenticates these plant materials, allowing for detection of 10% Hedysari Radix DNA mixed in with Astragali Radix.

To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractylodes is a sister group of the Carlina and Atractylis branch.

Molecular pharmacognosy has developed as a new borderline discipline. Using the method and technology of molecular pharmacognosy, a wide range of challenging problems were resolved, such as the identification of Mongolian medicinal raw materials, etiology of endangerment and protection of endangered Mongolian medicinal plants and animals, biosynthesis and bioregulation of active components in Mongolian medicinal plants, and characteristics and the molecular bases of Dao-di Herbs. So molecular pharmacognosy will provide the new methods and insights for modernization of Mongolian medicine.
