Evalution Of Phytochemicals, Antioxidant Potential, And Antibacterial Properties of Plant: Pennisetum Setaceum (Forssk.) Chiov

Pennisetum setaceum (Forssk.) Chiov. is an attractive grass plant that produces purple leaves. This plant is commanly called purple fountain grass. This plant belongs from the Poaceae family. Pennisetum setaceum (Forssk.) Chiov. is native to Africa. This reserch focused on the phytochemicals screening, antioxidant and antimicrobial activity of the plant Pennisetum setaceum (Forssk.) Chiov. Different plant parts like leaves and stem.Plant extract was prepared in the three different solvents like methanol, D.W., and hexane by cold extraction method. The qualitative analysis of plant parts shows that the secondary metabolites like alkaloids, phenols, tannins, phytosterols, and amino acids are present. The various quantitative methods like TPC, TTC, and TFC are used for total content determination. Methanolic extraction has the highest total content. In leaves methanolic extraction shows the highest value of TPC is 6.301±0.00 GAE/G and also the highest value of TTC with value of 3.358±0.071 TAE/g. Stem hexane extraction shows the highest value for TFC is 7.056±0.033 QE/g. DPPH and PMA assays were used for the determination of antioxidant activity in different solvents of plant extracts, which determine the reducing agent that is present in the different parts of the plant. In the DPPH assay, the highest IC50 value was present in the hexane extract of leaves with the value of 20.728. And in the PMA method, the highest total antioxidant capacity is shown in the D.W. extracts of the leaves with the value of 1.001 mg AAE/g. Antibacterial activity was checked against gram-positive and gram-negative bacteria. E. coli and Staphylococcus aureus bacteria were used for antibacterial activity checked in different plant extracts. The highest zone of inhibition is shown in the acetone extract of the stem with a 20 mm zone of inhibition.
