Non-toxic pyrrolizidine alkaloids from Eupatorium semialatum.
The leaves of Eupatorium semialatum were investigated for the occurrence of pyrrolizidine alkaloids. Although this type of alkaloids generally occurs in the Eupatorieae, only unusual non-toxic pyrrolizidines of the tussilagin type were identified. All compounds are methyl esters of the corresponding beta-amino acids.
متن کاملPoison hemlock (Conium maculatum L.).
One of the most poisonous species amongst higher plants is Conium maculatum. It is a very common nitrophile weed species, belonging to the Apiaceae (formerly Umbelliferae) family. It contains some piperidine alkaloids (coniine, N-methyl-coniine, conhydrine, pseudoconhydrine, gamma-coniceine), which are formed by the cyclisation of an eight-carbon chain derived from four acetate units. gamma-Con...
متن کاملCaffeic acid derivatives from Eupatorium perfoliatum L.
From the ethyl acetate soluble fraction of a methanol/water extract of the herb Eupatorium perfoliatum L. (Asteraceae) six caffeic acid derivatives have been isolated and identified by 1D- and 2D-NMR spectroscopic data. Besides the common quinic acid derivatives 5-caffeoylquinic acid (chlorogenic acid), 3-caffeoylquinic acid (neochlorogenic acid) and 3,5-dicaffeoylquinic acid, three up to now u...
متن کاملIntoxication with Poison Hemlock (conium Maculatum L.) in Calves
The case of spontaneous poisoning of 38 calves with Poison Hemlock (Conium maculatum) was described. The following indices were measured, among others: haemoglobin content (HGB), red blood cell counts (RBC), white blood cell counts (WBC), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), differential white ce...
متن کاملPHYSIOLOGICAL ECOLOGY Laboratory Rearing of Agonopterix alstroemeriana, the Defoliating Poison Hemlock (Conium maculatum L.) Moth, and Effects of Piperidine Alkaloids on Preference and Performance
Conium maculatum L. (Apiaceae), or poison hemlock, is an invasive plant native to Europe that has become extensively naturalized throughout North America. This species contains piperidine alkaloids, including coniine and -coniceine, that are highly toxic to vertebrates. C. maculatumwas relatively free from herbivores in North America until the accidental introduction 30 yr ago of its monophagou...
