Secondary metabolites such as pyrrolizidine alkaloids (PAs) play a crucial part in plant defense. PAs can occur in plants in two forms: tertiary amine (free base) and N-oxide. PA extraction and detection are of great importance for the understanding of the role of PAs as plant defense compounds, as

Plants are attacked by many different herbivores. Some will consume whole leaves or roots, while others will attack specific types of tissue. Thus, insight into the metabolite profiles of different types of leaf tissues is necessary to understand plant resistance against herbivores. Jacobaea
The relationship between structurally different pyrrolizidine alkaloids and western flower thrips resistance in F(2) hybrids of Jacobaea vulgaris and Jacobaea aquatica.

Segregating plant hybrids often have more ecological and molecular variability compared to parental species, and are therefore useful for studying relationships between different traits, and the adaptive significance of trait variation. Hybrid systems have been used to study the relationship between

Plants produce a variety of secondary metabolites (PSMs) that may be selective against herbivores. Yet, specialist herbivores may use PSMs as cues for host recognition, oviposition, and feeding stimulation, or for their own defense against parasites and predators. This summarizes a dual role of
Microsomal metabolism of pyrrolizidine alkaloids from Senecio jacobaea. Isolation and quantification of 6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine and N-oxides by high performance liquid chromatography.

The metabolism in vitro of four pyrrolizidine alkaloids from the poisonous plant Senecio jacobaea was studied. The pyrrolizidine alkaloids jacobine, jacoline, senecionine, and seneciphylline, all macrocyclic diesters of retronecine, were incubated with rat liver microsomes. Analysis of incubation
Variation in pyrrolizidine alkaloid patterns of Senecio jacobaea.

We studied the variation in pyrrolizidine alkaloid (PA) patterns of lab-grown vegetative plants of 11 European Senecio jacobaea populations. Plants were classified as jacobine, erucifoline, mixed or senecionine chemotypes based on presence and absence of the PAs jacobine or erucifoline. Due to the
Comparison of the toxicities of Senecio jacobaea, Senecio vulgaris and Senecio glabellus in rats.

The toxicity of Senecio jacobaea, S. vulgaris and S. glabellus to rats was assessed in a feeding trial. The plants were of similar toxicity, with a plant dry matter intake of about 20% of initial body weight being a lethal dose. Gas chromatography-mass spectrometry analysis demonstrated the presence
Effects of root herbivory on pyrrolizidine alkaloid content and aboveground plant-herbivore-parasitoid interactions in Jacobaea vulgaris.

The importance of root herbivory is increasingly recognized in ecological studies, and the effects of root herbivory on plant growth, chemistry, and performance of aboveground herbivores have been relatively well studied. However, how belowground herbivory by root feeding insects affects aboveground

The chronic toxicity of 10% dietary Senecio jacobaea (SJ) in guinea pigs was studied during a 365-d feeding trial. The SJ plant contains hepatoxic pyrrolizidine alkaloids (PA). The chronic lethal dose (LD100) of SJ for guinea pigs was 1,264 g/kg initial body weight or 526% of initial body weight

Tansy ragwort (Senecio jacobaea ) was evaluated for animal and human health hazard using the Salmonella/mammalian-microsome mutagenicity test. An acetone extract of tansy ragwort (TR) produced a negative mutagenic response for bacterial tester strains TA1535 and TA100 and a toxic response in tester

Plants produce a diversity of secondary metabolites (SMs) to protect them from generalist herbivores. On the other hand, specialist herbivores use SMs for host plant recognition, feeding and oviposition cues, and even sequester SMs for their own defense. Therefore, plants are assumed to face an
Hydrolysis rates of pyrrolizidine alkaloids derived from Senecio jacobaea.

Many of the commonly studied pyrrolizidine alkaloids (PAs) are built upon the subgroup retronecine (RET), which is released from the parent molecule by either base catalyzed or enzymatic hydrolysis of the ester linkages. The rate of appearance of RET in a hydrolytic study would thus reflect the rate
