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 assessproximate compositionandnutrientcontents of five medicinal plant speciescollected from NorthwestPakistan.Bupleurum falcatumandValeriana officinalisbelongs to humid regions, whileForsskalea tenacissima,Lavandula angustifoliaandOtostegia limbatabelongs to sub-humid regions. Proximateanalysis (total protein, fats, carbohydrate, ash, and moisture contents) were carried out followingmethods ofAssociation 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 revealedhigher concentration of macronutrients inF. tenacissimaand micronutrients inO. limbata. In conclusion, sub-humid region’s species are having higher nutritional value than humid region’s species.
