Area of Science:

  • Pharmacognosy
  • Molecular Biology
  • Industrial Quality Assurance

Background:

  • DNA barcoding, initially for plant identification, is now crucial for authenticating herbal drugs.
  • Integration into regulatory standards like the British Pharmacopoeia accelerates industrial adoption.
  • Current methods include morphological, chemical, and DNA-based techniques.

Purpose of the Study:

  • To evaluate DNA barcoding's role in industrial herbal drug authentication.
  • To introduce DNA-based identification into regulatory frameworks.
  • To develop rapid and reliable authentication protocols for raw materials.

Main Methods:

  • Application of DNA barcoding for herbal material identification.
  • Introduction of DNA methods into the British Pharmacopoeia with a reference standard.
  • Development of DNA barcode-targeted quantitative PCR and high-resolution melt curve tests.
  • Case study using *Rhodiola rosea* authentication.
  • Application of next-generation sequencing for comprehensive profiling of mixed herbal drugs.

Main Results:

  • Conventional DNA barcoding is not ideal for industrial quality control due to material complexity and process demands.
  • DNA barcode-targeted quantitative PCR and high-resolution melt curve tests offer rapid, robust, high-throughput screening.
  • Next-generation sequencing provides a complete biological profile of mixed herbal drugs, showing potential for industrial quality assurance.

Conclusions:

  • DNA barcoding methods are valuable but require adaptation for industrial settings.
  • Advanced DNA techniques like qPCR and NGS are promising for efficient and reliable herbal drug authentication.
  • Regulatory inclusion and development of specialized tests are key to advancing DNA-based quality control in the herbal industry.
