As a side note, both solvents and catalysts may act as reagents, but not as reactants, since the former are not consumed during a chemical reaction. Wagner's test A volume of 2 ml of each extract was treated with a few drops of Wagner's reagent. An "alkaloid" is a substance with nitrogen in the molecule, connected to at least two carbon atoms and must have at least one ring, but not necessarily heterocyclic, that definition has been proposed by Nowacki and Nowacka in 1965. The limiting reagent is entirely used at the end of a chemical reaction. 172.22. Reagents are added to a solution in order to test for, or cause a reaction.

Test for tannins compounds are present in medicinal plants including sapo- nins, tannins, avonoids, alkaloids, terpenoids, steroids, glycosides and proteins. The major ions and Sr concentrations and the Sr isotopic compositions of rainwater from four weather stations in the Ordos desert, Northwest China, were measured in this study. Magnesia mixture (reagent for phosphates and arsenates). CAS No. Alkaloid sample reacts with Wagner reagent (Iodine-potassium-iodide solution) which gives Brown colour precipitate. The principle underlying this method is the ability of alkaloid compounds, possibly present in the plant extracts, to couple their nitrogen atom with the heavy metal ions present in Mayer's and Wagner's reagent to form ion pairs that result in an insoluble yellow-red precipitate (Coe and Anderson 1996). Fig 2: Phyto chemical evaluation of herbal drugs Pre Phytochemical screening: Phytochemical examinations were carried out for all the extracts as per the standard methods.
