Comparing the antibacterial activity of plants against bacteria

Abstract

Plants and their secondary metabolites are potentially beneficial since they produce a number of medicinal substances. They have a variety of biological functions and characteristics that are influenced by various outside variables. The objective of this research is to examine the antibacterial activity of two plant extracts, Helicteresisora and Piper longum, against gramme positive bacteria, Staphylococcus epidermidis, and gramme negative bacteria, Escherichia coli, using the micro dilution method. Additionally, the quantity and efficiency of these extracts will be examined in relation to changes in extraction and storage temperatures. The extracts were extracted at 90°C temperatures. To determine whether Helicteresisora and Piper longum were present, qualitative testing and statistical test carried out. By the time the trials were over, it was determined that Helicteresisora appears to be more efficient against Escherichia coli and Staphylococcus epidermidis than Piper longum, as indicated by a graphical representation. it can be concluded that the inhibition zone of Helicteresisora and Piper longum against Staphylococcus epidermidis and Escherichia coli shows significant differences as most standard deviation values do not overlap
