ARTICLE INFO Abstract Traditionally, gum obtained from Astragalus gummifer are consumed as analgesic agent. Current study focused on the proximate, phytochemical and elemental analysis of methanolic extract of A. gummifer. In proximate analysis different nutritional constitutes like moisture, ash and total acidity in methanolic extract of A. gummifer was detected. In proximate screening highest ratio of ash (35.1 ± 2.0 %) indicating a richest bio-resource of vitamins. While the values for

Phytochemical screening was implemented for the identification of different bioactive compounds i.e. tannins, flavonoids, gum and mucilage, phenols, saponins, protein & amino acid, alkaloids in methanolic extract of A. gummifer. The results indicated that flavonoids, phenolic compounds, proteins & amino acids and gum & mucilage were present in the extract while saponins and tannins were not found. Mettalic screening was carried out for the quantification of different mineral elements i.e. Fe, Mn, Zn, Cr, Cu and Ni. The highest ratio was documented for Ni (8.69 ppm) followed by (4.73 ppm) for Cr. The lowest concentration was found for Mn measuring (5.30 ppm) while the values for Fe and Zn were recorded as (6.50 ppm and 6.04 ppm) respectively. The results obtained in this study clearly indicated that methanolic extract of A. gummifer is the rich source of secondary metabolites and certain mineral elements which support the use of this plant as stabilizing agent in the food, textile, leather, pharmaceutical, cosmetic and industries.
