Potential of the Ethanolic Extract of Matoa Leaves (Pometia pinnata J.R. & G.Forst) against Staphylococcus aureus bacteria

Abstract

Staphylococcus aureus is a bacterium that can cause several diseases in humans such as ulcers and wound infections. Matoa leaves contain phenolic and flavonoid compounds which are known to have antibacterial properties. The purpose of this study was to determine the antibacterial activity of the ethanolic extract of Pometia pinnata J.R. & G.Forst leaves against Staphylococcus aureus at concentrations of 10%, 20%, and 30%. This research was conducted by disc diffusion method on Mueller Hinton Agar (MHA) media. Antibacterial activity was measured by looking at the inhibition of the growth of S. aureus bacteria. Based on the results of the study, it was found that the ethanolic extract of matoa leaves was able to inhibit the growth of S. aureu bacteria with the average inhibition zones produced at concentrations of 10%, 20% and 30%, namely 11.06 mm, 15.07 mm, 16.07 mm and control ciprofloxacin positive was 28.10 mm. From the results above, it can be concluded that the ethanolic extract of matoa (Pometia pinnata) leaves has antibacterial activity against Staphylococcus aureus.

Rhizosphere actinobacteria isolated from Pometia pinnata and its antimicrobial activity

“…Pometia pinnata, often known as matoa is a plant originating from West Papua, Indonesia which is spread across several regions islands in Indonesia. Pometia pinnata is known as ornamental plants that can cure several diseases such as fever, diarrhea, flu, and diabetes (Pakaya et al 2021;Sidoretno 2022). Moreover, P. pinnata has been reported to have potential as antimicrobials agent (Irawan and Sirait 2020), due to potential secondary metabolite content of rhizosphere actinobacteria Actinobacteria isolated from P. pinnata rhizosphere has never been reported before as an antimicrobial agent.…”
