SOME ELEMENT CONTENTS SCREENING OF ECONOMICALLY IMPORTANT ENDEMIC Stachys iberica Bieb. subsp. iberica var. densipilosa Bhattacharjee (Lamiaceae)

Abstract

Atomic absorption spectrometry and spectrophotometry facilitates the reliable determination of mineral content during pharmaceutical quality control of medicinal plants. In this study, measurable amounts of Fe, Ca, Cu, K, Mg, Na and Zn were detected through flame atomic absorption spectrometry, B was detected by spectrophotometry in Stachys iberica Bieb. subsp. iberica var. densipilosa Bhattacharjee. Mean element contents in the herba of Stachys iberica Bieb. subsp. iberica var. densipilosa Bhattacharjee was, in descending order, Ca>Mg>K>Fe>Na>Zn>Cu. Ca was present in the highest concentrations (8725.42 ppm) while Cu was present in the lowest concentrations (13.15 ppm) of titled plant. Boron concentration of Stachys iberica Bieb. subsp. iberica var. densipilosa Bhattacharjee was determined as 6 mg kg^-1 dry wt (ppm.).
