Potential of Dayak Onion (Eleutherine palmifolia (L) Merr) Extract As Antibacterial Against Pseudomonas fluorescens

Abstract

Dayak onions (E. palmifolia (L) Merr) is a herb used as medicine and known to have antibacterial activity. This research aimed to evaluate antibacterial activity of Dayak onion (Eleutherine palmifolia (L) Merr) extract against fish pathogen Pseudomonas fluorescens. The method used in this study was extraction by maceration, UV-Vis spectrophotometry analysis on the extract and antibacterial activity test with Minimum Inhibitory Concentration (MIC) as well as disc diffusion test. The results of this study showed that the yield value was 8.87%. Based on UV-Vis analysis, it confirmed that extract of Dayak onion (Eleutherine palmifolia (L) Merr) contains predominantly flavonoids and phenols with its derivatives, that have antibacterial activity. The results of MIC and disc diffusion test showed potential antibacterial activity against P. fluorescens, as observed from the value of absorbance and inhibition zones that formed.

The Effect of Different Shading Level on Growth and Plant Biomass Character of Dayak Union (Eleutherine palmifolia (L.) Merr)

“…Umbi adalah bagian utama dari tanaman bawang Dayak yang paling banyak dimanfaatkan. Manfaat utama dari umbi bawang Dayak adalah lebih banyak dijadikan sebagai obat daripada sebagai bumbu dapur (Putra, 2018;(Dewi et al, 2017); (Fransira et al, 2019). Umbi merupakan organ penyimpan cadangan makanan yang mengandung beberapa senyawa bioaktif yang dimanfaatkan sebagai tanaman obat, antara lain: fenolik dan flavonoid (Shi et al, 2019); flavonoid, alkaloid, saponin, tanin dan steroid (Novaryatiin dan Ardhany, 2019).…”

The effect of peat soil and sandy soil on the growth of Eleutherine palmifolia and arbuscular mycorrhizal diversity

“…For years the Dayak people have believed that this introduced plant (from South America) could prevent and treat various diseases, including heart disease and anti-inflammatory (Quadros Gomes et al 2021). Clinically, the tuber of the E. palmifolia has functioned as an immunostimulant to optimize the body's immunity (Fransira et al 2019;Kamarudin et al 2020) to increase milk production, treat stroke, breast cancer, hypertension, and sexual disorders (Insanu et al 2014). Also, it treats infections caused by bacterial (Borges et al 2020;Fransira et al 2020;Jiang et al 2018).…”

It was reported by (Couto et al 2016;Insanu et al 2014) that E. palmifolia bulbs contain naphthoquinones, anthraquinones, and naphthalenes, which are beneficial for health.…”

Screening of Antibacterial Activity of Ethyl Acetate Fraction of Eleutherine palmifolia (L.) Merr Bulbs against Salmonella typhi

“…Eleutherine palmifolia (L.) Merr is empirically used to treat infectious diseases. It has been scientifically proven active against Pseudomonas fluorescens (Fransira, Yanuhar and Maftuch, 2019), Shigella dysenteriae (Wicaksono, Runadi and Firmansyah, 2018), and Escherichia coli (Mahmudah, Muntaha and Muhlisisn, 2019). E. palmifolia contains alkaloids, glycosides, flavonoids, phenolics, steroids, and tannins (Harlita, Oedjijono and Asnani, 2018;Mutiah et al, 2019;Limantara et al, 2020).…”
