What's the difference between groundsel and senecio?
Groundsel
Definition:
(v.) An annual composite plant (Senecio vulgaris), one of the most common and widely distributed weeds on the globe.
(n.) Alt. of Groundsill
Example Sentences:
(1) The toxicity of Riddell groundsel (Senecio riddellii) gavaged to calves at a known lethal rate was compared with the toxicity of riddelliine and riddelliine N-oxide, the pyrrolizidine alkaloids isolated from the plant, which were fed by intraruminal infusion.
(2) Selected case reports from closely controlled experimental feedings of Senecio jacobaea (tansy ragwort), S longilobus (threadleaf groundsel) and S riddellii (Riddell's groundsel) to cattle are presented to show that all 3 of these pyrrolizidine alkaloid-containing plants may not necessarily induce proximate toxicity, but may cause typical signs and death many months after the plants are ingested.
(3) The toxicity of Riddell's groundsel (Senecio riddellii) fed to calves in gelatin capsules, by gavage, or mixed in their hay ration was determined.
(4) On-line separations of pyrrolizidine alkaloids from extracts of Senecio jacobaea (tansy ragwort) and Senecio vulgaris (common groundsel) were done using an ammonium hydroxide-containing mobile phase.
(5) Four of the species extinct in England also became extinct globally: the penguin-like great auk; Mitten's beardless moss; York groundsel, a weed only discovered in the 1970s; and the Ivell's sea anemone, last seen in a lagoon near Chichester.
Senecio
Definition:
(n.) A very large genus of composite plants including the groundsel and the golden ragwort.
Example Sentences:
(1) In addition to the isolation of senecionine, seneciphylline, and retrorsine from Senecio vulgaris L., the presence of riddelline was confirmed by high resolution NMR spectroscopy.
(2) The toxicity of Riddell groundsel (Senecio riddellii) gavaged to calves at a known lethal rate was compared with the toxicity of riddelliine and riddelliine N-oxide, the pyrrolizidine alkaloids isolated from the plant, which were fed by intraruminal infusion.
(3) are metabolized in the ovine rumen to 1-methyl metabolites, whereas the macrocyclic ester PA of Senecio spp.
(4) The same compounds are also found in the essential oils of various plants, of which the occurrence of the cycloheptadiene-pheromone ectocarpene in Senecio isatideus (Compositae) is noteworthy.
(5) The effect of feeding a diet containing 5% tansy ragwort (TR) (Senecio jacobaea), a poisonous plant containing pyrrolizidine alkaloids (PA), on the blood and liver levels of copper, zinc, iron and vitamin A in broiler chicks was examined.
(6) Calves and cows (n = 45) were fed daily doses of dried prebud tansy ragwort (Senecio jacobaea) derived from a single plant collection made in Tillamook, Oregon.
(7) The combined effect of cyclophosphamide (CTX) and extracts of six patients belonging to Crotalaria and Senecio genera was assessed on experimental transplantable S180 (both ascitic and solid forms) tumour.
(8) The pyrrolizidine base present in Cynoglossum officinale (heliotridine) and its esters have a similar type of toxicity to the highly toxic and more familiar macrocyclic diester pyrrolizidine alkaloids of the pyrrolizidine base (retronecine), present in Senecio or Crotolaria species.
(9) A study of the toxic pyrrolizidine alkaloids contained in Senecio inaequidens D.C., an infestant species of the Senecio genus, widespread in the North East of Italy, is reported.
(10) Pyrrolizidine alkaloids derived from Senecio longilobus have been rapidly isolated and identified.
(11) Epidemiological, clinical, necropsy and histopathological data were accumulated during the study of 15 outbreaks of Senecio spp poisoning in cattle occurring during the last 3 y in the State of Rio Grande do Sul, Brazil.
(12) The metabolism in vitro of four pyrrolizidine alkaloids from the poisonous plant Senecio jacobaea was studied.
(13) Senaetnine is a new type of Senecio alkaloid with a dihydropyrrolizinone structure.
(14) Twenty horses of various ages had inadvertently ingested alfalfa hay contaminated with Senecio vulgaris.
(15) The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species.
(16) Twenty-five 1-week-old male chicks were fed for 6 weeks on a standard diet incorporating 7% dried and ground ragwort (Senecio jacobea).
(17) Acute toxicity, spasmolytic and hypotensive properties of the alkaloids senecionine, d-otocenine and floridanin isolated from Senecio Erraticum L. were studied.
(18) The results of experimental poisonings with Dichapetalum cymosum, Urginea sanguinea, Senecio retrorsus, Nicotiana glauca and prussic acid are discussed.
(19) A new secopyrrolizidine alkaloid, acetylanonamine, was isolated from Senecio anonymus.
(20) Selected case reports from closely controlled experimental feedings of Senecio jacobaea (tansy ragwort), S longilobus (threadleaf groundsel) and S riddellii (Riddell's groundsel) to cattle are presented to show that all 3 of these pyrrolizidine alkaloid-containing plants may not necessarily induce proximate toxicity, but may cause typical signs and death many months after the plants are ingested.
