Summary
Trace element analysis revealed significant differences between the northern and southern Wuji Baifeng Wan preparations. These variations are attributed to other medicinal components, not the core preparation itself.
Area of Science:
- Pharmacology
- Analytical Chemistry
- Traditional Chinese Medicine
Background:
- Wuji Baifeng Wan is a traditional Chinese medicine with distinct northern and southern preparations.
- Understanding the chemical composition, specifically trace elements, is crucial for quality control and efficacy.
Purpose of the Study:
- To analyze and compare the trace element profiles of northern and southern Wuji Baifeng Wan preparations.
- To identify the sources of variation between these two formulations.
Main Methods:
- Cluster analysis was employed to group trace element data.
- Atomic Absorption Spectroscopy (AAS) was used for the quantitative determination of trace elements.
Main Results:
- Cluster analysis indicated that the northern and southern Wuji Baifeng Wan preparations did not group together, suggesting significant compositional differences.
- Trace element analysis revealed substantial disparities between the Twelve Wuji Baifeng Wan (southern) and Wuji Baifeng Wan (northern).
- Minimal differences were observed between Chinese Taihe Chicken and Native Chicken, serving as a control.
Conclusions:
- The significant differences in trace element content between the northern and southern Wuji Baifeng Wan are primarily due to the inclusion of other medicinal ingredients.
- The core preparation method or base ingredients are less likely to be the cause of these observed variations.
