Adiantum capillus veneris is a medicinally essential plant used for the treatment of diverse infectious diseases. The study of phytochemical and antimicrobial activities of the plant extracts against multidrug-resistant (MDR) bacteria and medically important fungi is of immense significance. Extracts from the leaves, stems, and roots of Adiantum capillus veneris were extracted with water, methanol, ethanol, ethyl acetate, and hexane and screened for their antimicrobial activity against ten MDR bacterial strains and five fungal strains isolated from clinical and water samples. Ash, moisture, and extractive values were determined according to standard protocols. FTIR (Fourier transform infrared Spectroscopy) studies were performed on different phytochemicals isolated from the extracts of Adiantum capillus Veneris. Phytochemical analysis showed the presence of flavonoids, alkaloids, tannins, saponins, cardiac glycosides, terpenoids, steroids, and reducing sugars. Water, methanol, and ethanol extracts of leaves, stems, and roots showed significant antibacterial and antifungal activities against most of the MDR bacterial and fungal strains. This study concluded that extracts of Adiantum capillus veneris have valuable phytochemicals and significant activities against most of the MDR bacterial strains and medically important fungal strains.
Various solvent extracts from the whole plant of Thymus linearis were screened for their phytochemical and antimicrobial potentials. Preliminary phytochemi-cal screening of plant extracts showed the existence of terpenoids, flavonoids, tannins, alkaloids, glycosides and reducing sugars. Fourier transform infrared spectroscopy studies were carried out on various phytochemicals extracted from the exhibited T. linearis which resulted in the presence of different compounds like amides, aldehydes, carboxylic acid, ether, alcohol and ketones.
<p>In the present study various solvent extracts from the leaves of<em> Fernandoa adenophylla</em> were screened for their phytochemical and antimicrobial potentials. Preliminary phytochemical screening of leaves extracts showed the presence of alkaloids, glycosides, flavonoids, terpenoids, tannins, steroids, reducing sugars and anthracenes. Fourier transform infrared spectroscopic studies showed the presence of different functional groups for compounds like alcohol, aldehydes and ketones, saturated and unsaturated hydrocarbons, amides, amines, carboxylic acids, esters, and ethers. All the extracts showed significant antibacterial activities when tested against eight multidrug resistant bacterial strains isolated from urinary tract infection patients. It was concluded that the leaves extracts of<em> F. adenophylla</em> have several vital phytochemical constituents and significant antibacterial activities against multidrug resistant bacterial strains causing urinary tract infections.</p><p> </p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
