“…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).…”

Typhoid fever is an infection caused by the bacterium Salmonella typhi, spread through contaminated food or water. Typhoid fever can be treated with antibiotics, but at this time some pathogen microbes have been resistant to the available antibiotics. Antimicrobials derived from natural product might be the alternative to overcome antibiotic resistance. Eleutherine palmifolia (L.) Merr is empirically used to treat infectious diseases. E. palmifolia has chemical compounds of alkaloids, glycosides, flavonoids, phenolics, steroids, and tannins. This study aims to evaluate the antibacterial activity of ethyl acetate fraction against S. typhi. E. palmifolia bulbs were subsequently extracted using n-hexane solvents and followed by ethyl acetate solvents. The ethyl acetate fraction was tested for antibacterial activity using the disc diffusion method. The ethyl acetate fraction of E. palmifolia at the concentrations of 8, 6, and 8 mg/paper disc showed the diameters of the inhibition zone of 15.1±3.6, 15.3±3.3, and 16.9±1.9 mm, respectively. The conclusion of this study was the ethyl acetate fraction of E. palmifolia has a strong antibacterial activity against S. typhi.

Dayak onion (Eleutherine palmifolia (L.) Merr.) is one plant that can cure various diseases and symptoms such as constipation, dysuria, cancer, dysentery, ulcers, diabetes mellitus, hypertension, antihypercholesterol, antimelanogenesis and antioxidant. However, there is no report about the chemical composition and their isolation. The purpose of this research is to extract and isolate the alkaloid compounds from Dayak onion and to identify the alkaloids by UV and FTIR spectrophotometer.TLC of alkaloid extracts from the plants used in this study revealed the presence of these compounds by using Bouchardat's reagent to reveal characteristic orange bands of alkaloids. From the data obtained, The isolation of the crude alkaloid extract obtained two pure isolates, they are isolated A (Rf=0.51) and isolate B (Rf=0.57). Isolate A gives a maximum absorbance at 270 nm wavelength and isolate B at 271 nm. The results of FTIR showed the presence of aliphatic CH, CH 2 , C=O, C=C, C-N, C-O for isolate A and aliphatic CH, CH 2 , CH 3 , C=C, C-N, C-O for isolate B.Based on the above results, it can be concluded that Dayak onion has a potential of alkaloids constituents for further study.

Dayak onion bulbs are a plant originating from Kalimantan which has been used for generations to treat various diseases. This plant is quite easy to grow and develop in many places in Indonesia. The aims of the present study were to evaluate the antioxidant potential of the methanol extract of Dayak onion bulbs based on the total of the phenolic and flavonoids contents and also the antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging ability, ferric reducing power and total antioxidant capacity. The results showed the total phenolic and flavonoid methanol extract of Dayak onion bulbs were 14.49 ± 1.42 mg GAE/g dry weight and 5.41 ± 1.01 mg QE/g dry weight, respectively. Antioxidant activity as measured by the DPPH, total antioxidant capacity, and ferric reduction assay with IC50 values of 16.95 ± 1.58 μg/mL, 24.22 ± 2.51 µg/mL, and 85.40 ± 16.88 µg/mL, respectively. These results suggest that the methanol extract of Dayak onion bulbs has potential bioactive compounds with good antioxidant activity and can be developed as an effective and safe source of natural compounds for functional food or herbal medicine.
