The present study deals with the phytochemical examination of therapeutic importance of whole plant extract of Aerva lanata (L.) Juss. Ex. Schult. an important medicinal plant. Qualitative phytochemical analysis of the methanol and ethanol extracts prepared fromAerva lanata whole plant revealed the presence of alkaloids, anthraquinones, catechins, coumarins, flavonoids, phenols, quinones, saponins, steroids, sugar, glycosides, tannins and xanthoproteins. The FT-IR spectrum confirmed the presence of alkyl group, methyl group, alcohol group, ethers, esters, carboxylic acid and anhydrides. The petroleum ether, benzene, ethyl acetate, methanol and ethanol extracts of whole plant of Aerva lanata were tested against Bacillus thuringiensis, Bacillus subtilis, Streptococcus faecalis, S. pyogenes, Staphylococcus aureus, Enterococcus faecalis, Salmonella paratyphi A and B, Salmonella paratyphi,Proteus mirabilis, Proteus vulgaris, Escherichia coli, E. coli (ESBL), Klebsiella pneumoniae, Pseudomonas aeruginosa andP. aeruginosa (ESBL) by the agar disc diffusion method.
