Herbicidal activity of Thymbra capitata (L.) Cav. essential oil
2020
The bioherbicidal potential of Thymbra capitata (l.) Cav. essential oil (EO) and its main compound carvacrol was investigated. In in vitro assays, the EO blocked the germination and seedling growth of Erigeron canadensis L., Sonchus oleraceus (l.) L., and Chenopodium album L. at 0.125 µ
Bioactive Compounds in Wild Asteraceae Edible Plants Consumed in the Mediterranean Diet
2020
Three wild edible plant species belonging to the Asteraceae family, Crepis vesicaria L. (s.l.), Sonchus asper (L.) Hill s.l., and Sonchus oleraceus L., usually consumed in the Mediterranean diet, were tested for their nutritional composition and content of carotenoids, tocols, thiamine and riboflavin. Low amounts of thiamine and riboflavin were found. All species were sources of xanthophylls (violaxanthin, neoxanthin, lutein, zeaxanthin and β-cryptoxanthin) and carotenes (α-carotene, β-carotene, 9-cis-β-carotene and 13-cis-β-carotene). Lutein accounted for the highest content (about 4 mg/100 g). They had good tocol amounts, in particular α-tocopherol (about 2–3 mg/100 g). Taking into accoun…
Phenolic Extract from Sonchus oleraceus L. Protects Diabetes-related Liver Injury in Rats through TLR4/NF-κB Signaling Pathway
2019
Sonchus oleraceus Linn. is of great interest in scientific platform because it exhibits significant biological activities. This study investigated the liver protective effects and mechanism of phenolic extract from S. oleraceus (SOL) on Streptozotocin (STZ)-induced diabetic rats. SOL significantly increased both superoxide dismutase activity and glutathione level, while causing a reduction of malondialdehyde level in the liver. Moreover, SOL ameliorates STZ-induced liver function and pathological damages. Diabetic rats fed with S. oleraceus daily for 6 weeks showed significantly decreased levels of tumor necrosis factor alpha and interleukin-1β in the liver. Sonchus oleraceus decreased the …

A chemotaxonomic survey of Sonchus subgenus Sonchus
1993
Abstract Five species of Sonchus subgenus Sonchus were surveyed for their phenolic constituents. Seven flavonoids were identified: luteolin, luteolin-7-glucoside, apigenin, apigenin-3-glucoside, quercetin, quercetin-3-glucoside and quercetin-3-galactoside; three were phenolic acids; caffeic, chlorogenic and isochlorogenic; and two were coumarins: aesculetin and cichoriin. Their systematic significance for this genus is discussed.
Résistances aux herbicides : au Nord, c’étaient les Laiterons !
2016
SPEGESTAD; Contexte - Après des échecs de désherbage de laiteron épineux à l’aide d’herbicides inhibiteurs de l’ALS (groupe HRAC B) en culture d’endives, l’hypothèse de la présence d’une résistance à ces herbicides a été étudiée. étude - Des tests biologiques avec un herbicide du groupe B (rimsulfuron) ont été effectués sur des populations provenant de parcelles « à problème ». Le gène de l’ALS a également été séquencé afin de rechercher la présence de mutations causant une résistance aux herbicides inhibiteurs de l’ALS dans ces populations. résultats - Les tests biologiques ont montré l’existence d’une résistance au rimsulfuron dans les trois parcelles étudiées. Des mutations au codon 197 …
