Quantification of Metal Nutrients in Origanum vulgare L. Collected from North Western Himalayas
Journal Title: Journal of Chemistry and Applied Biochemistry - Year 2015, Vol 2, Issue 1
Abstract
Beneficial therapeutic properties are shown by a number of minerals, essential to human nutrition. Many of these nutrients are present in different parts of plants and also have a significant role in biological systems either with organic molecules such as metalloenzymes or independently like redox or catalytic reaction. The concentration (mg kg-1) of selected trace metals (Fe, Mn, Cu, and Zn) were examined in Origanum vulgare L. collected from ten locations in Uttarakhand by atomic absorption spectrophotometer. The metal contents in the samples were found at different levels. The mean concentration (mg kg-1) of Zn in plants ranged from 17.250 ± 0.30 to 48.500 ± 1.13collected from Rushi and Mukteshwer respectively while Fe in plants ranged from 234.460 ± 0.49 to 402.630 ± 0.51 mg kg1 in Origanum collected from Mukteshwer and Champawat respectively. Mean content of Cu in plants was found to be minimum in Origanum from Mukteshwer 6.620 ± 0.91 mg kg1 and maximum in Origanum from Kilbury (24.120 ± 0.17 mg kg1). The lowest mean concentration of Mn in plants was observed in Origanum from Mukteshwer (18.590 ± 1.37mg kg-1) and highest from Rushi (60.970 ± 0.86 mg kg-1). Origanum collected from all sites have metal values below PFA limits. These results are useful for the evaluation of the quality of consummate aromatic pants.
