Proximate and nutrient composition of medicinal plants of humid and sub-humid regions in North-west Pakistan

摘要

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.
