Antibacterial activity of indigenous Dayak onion (Eleutherine palmifolia (L.) Merr) was investigated. The Dayak onion was solvent extracted with n-hexane, ethyl acetate, and ethanol 96% consecutively. Each extract was tested its antibacterial activity towards methicillin-resistant Staphylococcus
A new naphthoquinone, named eleuthinone A ( 8), two new anthraquinones, named eleuthraquinone A and B ( 12, 13), a naphthalene derivative, named eleucanarol ( 14) were isolated from the bulbs of ELEUTHERINE AMERICANA, together with two new natural products previously synthesized, and nine known
Ready-to-eat foods were investigated for contamination with methicillin-resistant Staphylococcus aureus (MRSA), and the partially purified fractions from the bulb of Eleutherine americana were evaluated for their anti-MRSA activity. Partially purified fractions Ea6.3 and Ea9 demonstrated good
The anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) activity and the possible mechanism of action of a crude extract from red bulbs of Eleutherine americana Merr. were investigated. The crude ethanolic extract from E. americana produced minimum inhibitory concentrations (MICs) of
Eleutherin and eleutherol extracted from bulbs of Eleutherine bulbosa (Miller) Urb. (Iridaceae), collected in the Amazonian jungle and grown in Italy, were tested for biological properties. The extraction procedure and the results of antibacterial, cytotoxicity, and pharmacological assays are
The scavenging activities of crude ethanolic extract from Eleutherine americana, on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl free radicals were investigated. The results revealed that the extract produced IC(50) values of 8.4 microg/mL and 0.78 mg/mL on DPPH and hydroxyl free radicals,
The antibacterial activity of ethanolic extracts of selected Thai medicinal plants (Rhodomyrtus tomentosa (Aiton) Hassk., Quercus infectoria G. Olivier, and Eleutherine americana Merr.) against Campylobacter spp. was investigated. Sixty-five Campylobacter, including 39 isolates from humans and 26
Crude extract from the herb Eleutherine americana was investigated for its antistaphylococcal activity both in vitro and in a food system. The extract activity against Staphylococcus aureus was better during incubation at 35 degrees C than at 10 and 4 degrees C. The extract exhibited excellent
About 106 samples of ready-to-eat foods were purchased over a period of 3 mo out of which 76 (71.69%) were contaminated with Staphylococcus aureus. S. aureus isolated from the food samples were characterized phenotypically using traditional biochemical methods. Ninety-four percent of the isolates
This study aimed to determine the survival and antibacterial activity of Lactobacillus plantarum TISTR1465 encapsulated with Eleutherine americana oligosaccharide extract. Capsules were stored at 4 °C for 0, 2, and 4 weeks. The encapsulated cells were evaluated for their survival after sequential
