This study aimed to determine the total antioxidant capacity of the essential oil (EO) of leaves of Bidens pilosa (Linn. Var. Radita) used as protectant of stored grains in Northern Cameroon. EO was characterized by GC-FID, antioxidant activity (AA) was determined by combining: evaluation of

The aim of this study was to evaluate antioxidant activities and cytotoxicity against human tumor cell lines of extracts from Bidens pilosa Linn. var. radiata Sch. Bip. (BP). Total phenolic and flavonoid contents of the extracts were determined by ultraviolet spectrophotometry. Furthermore, the

Extracts from herb and flowers of Bidens tripartita L. (Asteraceae), obtained using solvents of different polarity, were studied for their radical scavenging effects. Antioxidant activities of pure flavonoids: flavanomarein (isookanin 7-O-glucoside), cynaroside (luteolin 7-O-glucoside) and luteolin,

3',4',6,7-Tetrahydroxyaurone (1a), an aurone isolated from Bidens frondosa, and five analogues (1b-1f) were synthesized from pyrogallol in three steps. The antioxidative activity of 1a-1f was determined by the superoxide free radical and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging

A bioassay-oriented approach led to the isolation of 11 compounds, including three new natural flavonoids, (2S)-isookanin 7-O-α-L-arabinopyranoside (1), (2S)-isookanin 7-O-(2''-acetyl)-α-L-arabinopyranoside (2), and luteolin 7-O-β-D-glucopyranosyl-(1 → 6)-β-D-galactopyranoside (6), from Bidens

Background: According to recent studies, reactive oxygen is the leader of human metabolic disease development. The use of natural antioxidants is the best way to stop or prevent this problem. Therefore, the aim of this study was to evaluate the antioxidant and anti-inflammatory activities and to

Bidens pilosa is an annual plant from tropical America with anti-inflammatory properties in hepatitis, laryngitis, headache and digestive disorders, among others. Its wide pharmacological applications can be attributed to its chemical composition, with inhibitory effects on pathogenic microorganisms

We evaluated the antioxidant activity of natural compounds in water-soluble and lipid-soluble phases and found that ferulic acid, quercetin and caffeic acid showed stronger activity in the water-soluble phase. Various fractions isolated from Bidens pilosa showed this activity mainly in the

OBJECTIVE Bidens species are used for their antidiabetic properties traditionally in many countries. Aim of this study is to evaluate hypoglycaemic and antidiabetic activity of Bidens tripartita extract and to identify its active compounds through bioactivity guided isolation

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

Using synthetic chemicals in industry and agriculture has led to several environmental problems. Thus, plant products derived from volatile oils (VOs) could be a potential green source for bioherbicides. Little is known about the VOs of Lactuca serriola. Hence, the present study aimed to

Bidens pilosa L. var. radiata (BPR, Asteraceae) is a commonly used folk medicine for treating various disorders such as diabetes, inflammation and hypertension. Recent studies to determine its chemical composition have revealed three di-O-caffeoylquinic acids (DiCQAs) and three polyacetylene

The essential oil (EO) of Xanthium strumarium L. leaves (family: Asteraceae) was extracted by hydrodistillation, and then analyzed by gas chromatography-mass spectrometry (GC-MS). Forty-three essential compounds were identified. The sesquiterpenoids represented the major constituents (72.4%),

Bidens pilosa L. was a Cd hyperaccumulator. This experiment determined the effects of different soil pH (adjusted by weak acid and alkali at 4.83, 6.81, and 7.84, respectively) and nitrogen ((NH₄)₂SO₄, Ca(NO₃)₂) on B. pilosa phytoextracting Cd

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
