Although it is an important constituent of vitamin B 12 , yet its higher exposure produces significant ramifications in crop plants. It affects biomass and concomitantly reduces crop yield that in turn causes substantial financial loss to farmers. To counter this heavy metal toxicity, the plants have devised mechanisms either to detoxify or accumulate the contaminants. Further, there are various bioremediation strategies that can be used to get rid of Co from the given medium. Phytostabilisation, phytoextraction, rhizofiltration are some of the techniques used worldwide to reduce cobalt in the fields. This review emphasis upon the uptake, transportation, accumulation of cobalt in plants and discusses the remedial strategies available presently to effectively remove it from mediums like soil and water bodies.

This stress can be overcome by administration of natural polyphenols. The Acacia catechu Willd. has many refrences available in Ayurveda as important disease curative plant. Its leaves are investigated for ameliorating oxidative stress in present work. Leaves of A. catechu were extracted with 80% methanol to get methanol extract (AME). It was assessed for antioxidant activity using DPPH, ABTS, CUPRAC, ferric ion reducing, superoxide scavenging and peroxyl radical scavenging assays. DNA protective activity was also investigated using plasmid nicking assay. Further, antiproliferative activity was determined using MTT assay in various human cancer cell lines. The quantification of polyphenols was done by UHPLC analysis. Results confirmed that polyphenols of A. catechu were successful in normalizing oxidative stress. AME was found to be most effective in scavenging ABTS radicals while least effective in scavenging ferric ions. UHPLC analysis showed abundance of ellagic acid, rutin and quercetin in AME. Further, AME showed maximum antiproliferative activity against Hep G2 cancer cells. It is concluded that the polyphenols from A. catechu effectively remediates oxidative stress and hence can be used in curing numerous dreadful diseases.

They along with their complexes have found use in drug development since last decade (Gianferrara et al. 2009; Li et al. 2015). Their ability to exist in a number of oxidation states and reacting with other oppositely charged species has been exploited in medicinal chemistry. Some of the transition metals have been reported to possess antimicrobial, antifungal, antidiabetic and anticancer properties (Singh 2014). Different metal complexes viz., Ru(III), Co(II), Cu(II) nitrate, Pd(II) chloride, and coordination complexes of Pt(II), As, Sb, Bi, V, Fe, Rh, Ti and Ga have been investigated for their anticancer activities by various workers (
