Trace element analysis of some copper containing herbs

Area of Science:

• Ethnobotany
• Analytical Chemistry
• Pharmacognosy

Background:

• The Siddha system of medicine traditionally utilizes medicinal plants containing various metal constituents for therapeutic purposes.
• Understanding the precise elemental composition of these plants is crucial for validating their medicinal claims and ensuring safety.
• Copper and manganese are among the essential trace elements with known biological roles, often found in medicinal flora.

Purpose of the Study:

• To quantify the copper and manganese content in selected medicinal plants used in the Siddha system.
• To identify plants with significant concentrations of these specific metal constituents.
• To provide scientific validation for the traditional use of these plants in Siddha medicine.

Main Methods:

• Selected copper-containing medicinal plants, as per Siddha literature, were subjected to rigorous analysis.
• Atomic Absorption Spectrophotometry (AAS) was employed for the precise quantitative determination of metal ions.
• Comparative analysis of copper and manganese levels across different plant species was performed.

Main Results:

• Mangifera indica and Coccinia indica exhibited notably higher concentrations of copper among the analyzed plants.
• Coccinia indica, Aloe perfoliata, Cassia auriculata, and Nelumbium nicifera were found to contain significant levels of manganese.
• Elemental profiling confirmed the presence and varying amounts of copper and manganese in the studied Siddha medicinal plants.

Conclusions:

• The findings scientifically support the traditional Siddha use of Mangifera indica and Coccinia indica for their rich copper content.
• The presence of manganese in Coccinia indica, Aloe perfoliata, Cassia auriculata, and Nelumbium nicifera warrants further investigation into their therapeutic applications.
• This study highlights the importance of elemental analysis in validating traditional medicinal systems and identifying potent phytominerals.
