Summary
The growing botanical supplement market faces quality issues due to rapid introduction of new ingredients. Ensuring botanical ingredient quality requires advanced authentication tools and analytical methods for safety and efficacy.
Area of Science:
- Pharmacognosy and Phytochemistry
- Natural Product Chemistry
- Food Science and Technology
Background:
- The US botanical dietary supplement market has experienced significant growth over the past 15 years.
- The rapid expansion has led to the use of novel botanical ingredients without a complete scientific understanding.
- This knowledge gap contributes to issues like misidentification, adulteration, and potential toxicity of botanical products.
Purpose of the Study:
- To review recent scientific work concerning the quality and safety of botanical dietary ingredients.
- To highlight challenges and approaches in ensuring the quality of botanical ingredients, including contamination.
- To emphasize the need for improved tools and methods for botanical authentication and analysis.
Main Methods:
- Review of recent scientific literature on selected botanical ingredients (Ephedra, Citrus species, Hoodia gordonii, Teucrium, isoflavones).
- Examination of studies on mycotoxin contamination in botanical products.
- Discussion of analytical techniques for botanical authentication and bioactive constituent identification.
Main Results:
- Several botanical ingredients illustrate the complexities of quality control in the current market.
- Mycotoxin contamination is a significant concern in botanical products.
- Existing analytical methods and authentication tools are insufficient for ensuring consistent quality and safety.
Conclusions:
- There is a critical need for robust tools for botanical authentication.
- Development of methods for reproducible extraction of bioactive constituents is essential.
- Improved analytical techniques are required for identifying bioactive compounds and detecting contaminants, thereby enhancing overall quality and safety.
