Abstract
The study was carried out to assess proximate composition and nutrientcontents of five medicinal plant species collected from Northwest Pakistan.Bupleurum falcatum and Valeriana officinalis belongs to humid regions, whileForsskalea tenacissima, Lavandula angustifolia and Otostegia limbata belongs to sub-humid regions. Proximate analysis (total protein, fats, carbohydrate, ash, and moisture contents) were carried out following methods of Association of Official Analytical Chemists. Macronutrients (Ca, Mg, Na, K) and micronutrients (Fe, Cu, Pb, Zn, Ni, Cr, Co, Mn) were analyzed using atomic absorption spectrometry. Results revealed higher concentration of macronutrients in F. tenacissima and micronutrients in O. limbata. In conclusion, sub-humid region’s species are having higher nutritional value than humid region’s species. Key words: Proximate analysis, micro and macro nutrients, medicinal plants, humid region, sub-humid region.
