Summary
Traditional processing of Mylabris, including stir-frying with rice and removing specific body parts, is scientifically validated. This method alters trace element levels, reducing harmful elements like lead and arsenic.
Area of Science:
- Pharmacology and Toxicology
- Traditional Chinese Medicine
- Analytical Chemistry
Background:
- Mylabris is used in traditional medicine, but its processing methods require scientific validation.
- Understanding trace element changes during processing is crucial for safety and efficacy.
Purpose of the Study:
- To investigate the scientific basis of traditional Mylabris processing.
- To quantify changes in 11 trace elements before and after processing.
Main Methods:
- Analysis of 11 trace elements (Cu, Mn, Zn, Fe, Mg, Ca, K, Pb, Cd, As, Hg) using Flame AAS, Graphite Furnace AAS, and Hydride generation AAS.
- Comparison of trace element content in raw and processed Mylabris samples.
Main Results:
- Trace element content ranked: K > Mg > Fe > Ca > Zn > Mn > Cu > Pb > As > Hg > Cd.
- Processing reduced Pb, As, Hg, Cd, and Fe; increased Cu, Mg, and Ca.
- Higher Hg and Pb in head, legs, and wings; highest As in inner wings.
Conclusions:
- Traditional processing, including stir-frying with rice and removing head, legs, and wings, is scientifically supported.
- The processing method effectively modifies trace element profiles, potentially enhancing safety.
