There are roughly 1,300 species of Acacia worldwide which about 950 species are native to Australia and the remainder spread around the dry tropical to warm temperate regions of both hemispheres, including Africa, southern Asia, and the Americas.3. They are commonly found in the soapwort plant, whose roots were once used as soap. The seed coats are removed manually to get NSK. Drugs from plants extraction, purification & analysis. precipitation was complete. test). The aqueous extract and ethyl acetate, N-butanol and residual fractions of A. nilotica extracts were subjected to qualitative chemical screening for identification of various classes of active chemical constituents.7, 9. Sugars, Finally, n-butanol easily removed using rotatory evaporator under vacuum, and the remaining saponin residue stays in the round-bottomed flask. Saponins or saponosides set up a large and frequent group of heterosides in plants and are characterized by their surface-active properties, Saponins dissolve in water by forming a foaming solution due to their tension-activity; hence, these substances take their name from Latin (Sapo, saponis: soap). triterpenoids, The tests for tannins and polyphenols were carried out by subjecting the plant extracts in Ferric chloride test. layer confirmed the results. Sulphuric acid. plants flavonoids (pews One gm from it is accurately weighed and extracted with water (15 ml 6) over a steam water bath. The saponins content was calculated using standard formulae.

Among the Oriental drugs, many herbal drugs (Table 1) contain saponin as their principal constituents (Lacaille-Dubois M. A. et al., 1996; Osamu Tanaka, 1990). Haemolytic and antimicrobial activities of saponinrich extracts from guar meal. acid, indicated the presence of flavonoids. Maximum D2 amplitude (Z value) is obtained when a 1000-fold or greater molar ratio of TPA is used at pH 11. This solution may dilute with water, and directly subjected to a solvent extraction process using n-butanol and separating funnel.
