Electrochemical Analysis of Water Extracts from seeds of Trachyspermum ammi and Nyctanthes arbor-tristis in Bengal and Determination of Heavy Metals

Seeds of Trachyspermum ammi and Nyctanthes arbor-tristis in Bengal have a great medicinal importance in Bengal. They possess immunostimulant, antiviral, antibacterial and antifungal activities in human life. Various parts of plants can absorb metals from soil as well as from deposits on the parts exposed to the air from polluted environments. Heavy metal contamination with the medicinal plants is a serious concern due to its implications on human health. Atomic Absorption Spectroscopy (AAS) is used for determination of content of heavy metals like Cu, Zn, Fe, Cd, Cr, Co, Pb, Ca, K, Mg, Na, Hg and Se from water extract of Trachyspermum ammi seeds and Cu, Zn, Fe, Cd, Cr, Pb, Ca, K, Mg, Na and Se from water extract of Nyctanthes arbor-tristis seeds, were detected in AAS. Cyclic voltammetry (CV) analysis shows the rapid deterioration of reducing strength of antioxidant activities of water extracts.The main objective of this study was to determine nutritional status for heavy metals content and rapid detection of reducing strength as a part of antioxidant activities.
