Abstract

The traditional medicines involve the use of plant extracts particularly the bioactive components present in it. This type of study provides the health application at affordable cost. Secondary metabolites in plants are responsible for various medicinal uses of plants. Hence in the present study phytochemical screening of Sennauniflora (Mill.) H.S. Irwin &Barneby was carried out. Qualitative phytochemical analysis of this plant confirms the presence of various phytochemicals like Alkaloids, Flavonoids, Quinones, Saponins, Sterols, Terpenoids, Tri terpenoids and etc., of Ethanol, Methanol, Acetone, Hexane and Water extracts by Maceration method. The Antimicrobial activity of the above five extracts was also studied for six different microorganisms by zone inhibition method. Methanol and Hexane extracts have good zone inhibition ranges against microorganisms. Every parameter is compared with a standard drug. The results suggest that this plant extracts possess potential antimicrobials and lead to the isolation of novel compounds.

Keywords: Sennauniflora, Maceration, phytochemical screening, bioactive components, antimicrobial activities.
