Summary
Trace elements like zinc, copper, manganese, and iron are abundant in traditional Chinese medicines. This study quanties these essential minerals, finding variations linked to specific medicinal functions.
Area of Science:
- Analytical Chemistry
- Pharmacology
- Traditional Chinese Medicine
Background:
- Traditional Chinese Medicine (TCM) utilizes various herbs for health benefits.
- The role of trace elements in TCM efficacy is increasingly recognized.
- Understanding elemental composition can validate TCM properties.
Purpose of the Study:
- To quantify zinc (Zn), copper (Cu), manganese (Mn), and iron (Fe) in 20 types of beneficial TCMs.
- To investigate the relationship between trace element content and TCM classifications.
- To provide scientific data supporting TCM research.
Main Methods:
- Flame Atomic Absorption Spectroscopy (FAAS) was employed for elemental determination.
- Standard addition method was used to ensure accuracy, yielding high recovery rates (96.8%-104.3%).
- Relative Standard Deviation (RSD) below 2.0% confirmed method precision.
Main Results:
- All 20 TCMs analyzed were rich in Zn, Cu, Mn, and Fe.
- Hematonic TCMs exhibited the highest iron content.
- Qi-invigorating and maletonic TCMs showed higher levels of Zn and Mn, while Yin-nourishing drugs had lower Fe content.
Conclusions:
- Beneficial TCMs are a significant source of essential trace elements.
- Specific trace element profiles correlate with different TCM functional categories.
- These findings offer a scientific basis for understanding TCM actions and quality control.
