SCREENING OF AERVA LANATA LINN. FOR PHARMACOGNOSTIC AND ANTIMICROBIAL ACTIVITY
Journal Title: International Journal of Pharmacognosy - Year 2017, Vol 4, Issue 4
Abstract
Aerva lanata has been used in traditional medicine for many years and used for the treatment of urinary bladder and kidney stones. The aim was to study the pharmacognostic characters and antimicrobial activity of important medicinal plant Aerva lanata (Amaranthaceae). The physicochemical, phytochemical and fluorescence analysis of powdered aerial and root parts of Aerva lanata was performed according to the standardization procedures recommended by the World Health Organization. The physicochemical parameters such as total ash, acid insoluble ash, water soluble ash reveals that the plant has less amount of carbonates, silicates and are less affected by contamination and inorganic compounds. The various colours obtained by fluorescence were analysed and the moisture content of aerial and root parts were found to be 37.5%, 35.33% respectively. The preliminary phytochemical screening showed the presence of alkaloids, saponins, terpenoids, flavonoids, proteins, glycosides, coumarins, carbohydrate, steroids, tannins, phenols and phytosterols. The antimicrobial activity performed of Aerva lanata on Pseudomonas aeruginosa, Klebsiella pneumonia, Bacillus substilis, Streptococcus mutants, Escherchia coli, Staphylococcus aureus showed maximum activity against gram negative bacteria on aerial parts of Aerva lanata. Thus the results of the present study can serve as a valuable source for the identification of this plant and their active components in future investigations.
