The chemical composition of the essential oil obtained from the roots of Bidens tripartita L. by hydrodistillation was investigated by gas chromatography-mass spectrometry. In total, 106 compounds were identified (97.1% of the total oil). The main components of the oil were α-pinene (15.0%),

Diseases caused by malaria parasites and pathogenic bacteria were thought to be on the brink of eradication in the 1950-1960s, but they have once again become a serious threat to mankind as a result of the appearance of multidrug resistant strains. The spread of these multidrug resistant organisms

BACKGROUND Bidens pilosa and Dichrostachys cinerea extracts were investigated for the antibacterial properties against waterborne diarrhoeagenic bacteria. METHODS The plant materials were extracted using the direct and serial exhaustive methods using solvents of varying polarities, namely, hexane,

Crude extracts from 21 South African medicinal plants, traditionally used for ailments of an infectious or septic nature, were screened for in vitro antibacterial activity using the agar diffusion and dilution methods. Almost all the activity exhibited was against Gram-positive bacteria, with 12 of

Currently multiresistant Staphylococcus aureus is one common cause of infections with high rates of morbidity and mortality worldwide, which directs scientific endeavors in search for novel antimicrobials. In this study, nine extracts from Bidens pilosa (root, stem, flower and leaves) and Annona

Due to the current challenges faced by the increasing rate of drug-resistant bacteria, attention is gradually shifting from synthetic antimicrobial chemical compounds to natural products that are ecofriendly with a wide spectrum of properties. The aim of this research was to successfully fabricate

The objective of this study was to screen extracts of twenty Eastern European medicinal plants, using wild-type and reporter Chromobacterium violaceum bioassays, for novel components that target bacterial cells and their quorum sensing (QS) communication systems. Three types of activity and their

A resurgence of interest has developed in wild vegetables for their possible medicinal values in diets. Wild plant species provide minerals, fibre, vitamins and essential fatty acids and enhance taste and color in diets. For this reason, the nutritional, phytochemical, antioxidant and antibacterial

Whole plant-parts of Bidens pilosa were powdered and extracted in concentrated hexane, acetone, ethanol, methanol and water. The extracts were tested for antimicrobial activity against Escherichia coli (25922), Bacillus subtilis (ATCC 6051), Enterococcus faecalis (51299) Staphylococcus aureus (ATCC

The aim of this study was to determine the antibacterial and antifungal properties of the extracts, subextracts and essential oils of Bidens tripartita flowers and herbs. In the study, twelve extracts and two essential oils were investigated for activity against different Gram-positive Bacillus

This study was performed to evaluate the antimicrobial activities of extracts of Bidens pilosa, Galinsoga ciliata, and Eryngium foetidum against 6 clinical strains of Helicobacter pylori in vitro and in vivo. Broth microdilution method was used in vitro. In vivo, Swiss mice were inoculated with H.

The ethanol extracts of Bidens pilosa (whole plant), Bischofia javanica (leaves), Elmerillia papuana (root bark) and Sigesbekia orientalis (whole plant) were partitioned (petrol, dichloromethane, ethyl acetate). The crude ethanolic extracts and all the obtained fractions showed a broad spectrum of

We evaluated the antioxidant, antibacterial, and anti-inflammatory activities of honey made from different floral sources, including the medicinal herb Bidens pilosa, fruit trees, Dimocarpus longan, Litchi chinensis, and Citrus maxima, the Taiwanese endemic plant Aglaia formosana, and a multifloral

The dried aerial parts of Bidens pilosa L. were extracted with petrol ether, chloroform, methanol, and methanol/water. The petrol ether and the methanol/water extracts showed some antimicrobial activity. Fractionation of the extracts yielded well known substances, most of which have, however, not

Bidens pilosa is used in various folk medicines such as antimalarial, antibacterial, blood pressure-lowering, and antihyperglycemic agents. Phytochemical investigation of the aerial parts of this plant yielded 10 polyacetylenes and 9 flavonoids, including four new polyacetylenes (5, 7- 9) and one
