Summary
This study quantified inorganic elements in Flos Chrysanthemi and Flos Chrysanthemi Indici using atomic absorption spectrometry. Flos Chrysanthemi contains high levels of Nickel, Zinc, Iron, and Lead, while Flos Chrysanthemi Indici is rich in Manganese and Calcium.
Area of Science:
- Analytical Chemistry
- Pharmacognosy
- Traditional Chinese Medicine
Background:
- Flos Chrysanthemi and Flos Chrysanthemi Indici are traditional Chinese medicines with potential therapeutic benefits.
- Understanding their elemental composition is crucial for quality control and elucidating their medicinal properties.
Purpose of the Study:
- To determine and compare the content of specific inorganic elements in Flos Chrysanthemi and Flos Chrysanthemi Indici.
- To provide foundational scientific data for further research into the medicinal efficacy and elemental relationships of these herbs.
Main Methods:
- Flame Atomic Absorption Spectrometry (FAAS) was employed for quantitative analysis.
- The standard addition method was utilized to ensure accuracy, achieving recovery rates between 94.20% and 110.50% with relative standard deviations (RSDs) below 4.12%.
Main Results:
- Flos Chrysanthemi demonstrated higher concentrations of Nickel (Ni), Zinc (Zn), Iron (Fe), and Lead (Pb).
- Flos Chrysanthemi Indici showed elevated levels of Manganese (Mn) and Calcium (Ca).
Conclusions:
- Significant differences in elemental profiles were observed between Flos Chrysanthemi and Flos Chrysanthemi Indici.
- The elemental data provides a scientific basis for investigating the correlation between elemental content and the traditional medicinal uses of these Chrysanthemum species.
