Summary
This study analyzed trace elements in pagoda flowers using FAAS, finding rich metal content. Pagoda flowers offer high nutritional value due to abundant essential minerals like potassium and calcium.
Area of Science:
- Analytical Chemistry
- Environmental Science
- Nutritional Science
Context:
- Trace element analysis is crucial for understanding plant nutritional value and potential environmental impacts.
- Pagoda flower (Clerodendrum হইবে) is a plant with traditional uses, necessitating scientific evaluation of its composition.
Purpose:
- To simultaneously determine twelve trace elements (K, Na, Ca, Mg, Pb, Cd, Cu, Mn, Co, Zn, Cr, Fe) in pagoda flowers using Flame Atomic Absorption Spectroscopy (FAAS).
- To assess the nutritional value of pagoda flowers based on their trace element profile.
Summary:
- Flame Atomic Absorption Spectroscopy (FAAS) was employed to quantify twelve trace elements in pagoda flowers.
- The method demonstrated good precision (RSD 0.07%-2.31%) and accuracy (recovery 97.0%-107.0%).
- Results indicated a high concentration of metal elements, with the order K > Ca > Mg > Na > Fe > Zn > Cu > Mn > Co > Pb > Cr > Cd.
Impact:
- The findings suggest pagoda flowers are a rich source of essential minerals, highlighting their high nutritional value.
- This research provides valuable data for the potential use of pagoda flowers in food or traditional medicine.
- The study contributes to the understanding of plant-based mineral content and its implications for human health.
