The antibacterial and antifungal activities of methanol extract, ethyl acetate, dichloromethane, n-hexane, n-butanol and chloroform fractions of Senecio inaequidens DC. and Senecio vulgaris L. were assayed. The hexane extract of Senecio vulgaris L. (MIC 0.031 mg/ml) showed significant activity

From a methanol extract of dried-ground aerial parts of Senecio lyratus, an anti-fungal and anti-bacterial active compound was isolated and identified as beta-sitosterol by spectroscopic analysis.

Ingestion of pyrrolizidine alkaloids, naturally occurring plant toxins, causes illness and death in a number of animal species. Senecio jacobaea pyrrolizidine alkaloids cause significant economic losses due to livestock poisoning, particularly in the Pacific Northwest. Some sheep are resistant to

The chemical composition of the essential oil obtained from Senecio graveolens (Compositae) was analyzed by GLC-MS and the components identified were: isovaleraldehyde, alpha-pinene, alpha-phellandrene, alpha-terpinene, p-cymene, sabinene, gamma-terpinene, 1-methyl-4-isopropenylbenzene, terpinolene,

Senecio scandens Buch.-Ham. ex D. Don (Compositae) is a crucial source of Chinese traditional medicine with antibacterial properties. We constructed a cDNA library and obtained expressed sequence tags (ESTs) to show the distribution of gene ontology annotations for mRNAs, using an individual plant

The effect of a natural sesquiterpene ketone, 9,10-dehydrofukinone (DHF), on pathogenic Staphylococcus aureus and Pseudomonas aeruginosa strains isolated from chronic infectious processes, was the focus of the present study. Lipophilic DHF produced important antibacterial synergistic effects in

OBJECTIVE To investigate activity-guided isolation and identification of anti-Staphylococcus aures components from Senecio tenuifolius Burm. F. (S. tenuifolius). METHODS Hexane, chloroform, ethyl acetate, methanol and aqueous extracts of S. tenuifolius were prepared by soxilation for antimicrobial

Senecio scandens Buch.-Ham. ex D. Don, an important antibacterial source of Chinese traditional medicine, has a widespread distribution in a few ecological habitats of China. We generated a full-length complementary DNA (cDNA) library from a sample of elite individuals with superior antibacterial

Senecio punae Cabrera (Asteraceae-Senecioneae) is an endemic species from Puna semi-desert region of Argentina.The major compound, 4p,5p-eremophil- 7(11)9-dien-8-one, also known as dehydrofukinone (D), was isolated from the diethyl ether extract (E) of the plant. The phytochemical constituents from

BACKGROUND In the altiplano of Northern Chile the plant Senecio nutans is habitually used as an infusion to relieve the effects of altitude sickness (locally known as "puna"). It is also used to alleviate the bronchitis, whooping cough, asthma, stomachache, tiredness and fever. The extreme

Senecio nutans Sch. Bip., S. viridis var. viridis Phill. and S. spegazzinii Cabrera are native species used in traditional medicine of northwestern Argentina. The total phenolics, flavonoids and caffeoylquinic acids contents, as well as radical scavenging, antioxidant, hemolytic and cytotoxic

Investigation of a CH(2)Cl(2) extract of the aerial parts of Senecio aegyptius var. discoideus afforded nine eremophilane compounds, of which six are new (1-6), namely, 1beta-hydroxy-8alphaH-eremophil-7(11),9-dien-8beta,12-olide (1), 1beta,8alpha-dihydroxyeremophil-7(11),9-dien-8beta,12-olide (2),

The search for anti-infective activity in the antipyretic plant Senecio smithioides was conducted. Petroleum ether (PE), dichloromethane (CH2Cl2), ethyl acetate (EtOAc) and hydroethanolic (96% EtOH) extracts, and compounds 9-oxoeuryopsin (1), epoxydecompostin (2) and senecionine (3) were obtained

The antimicrobial and cytotoxic activities of extracts from Senecio samnitum Huet are reported. Extracts from S. samnitum were able to inhibit the in vitro proliferation of four human tumor cell lines. The dichloromethane extract demonstrated effective cytotoxic activity with IC50 of 22.89 microg
