Rhagadiolus stellatus Gaertn., a Mediterranean member of the Cichorieae tribe of the Asteraceae family used as a food plant, was analyzed for its spectrum of phenolic compounds. Kaempferol 3-O-β-glucoside 1, kaempferol 3-O-β-rutinoside (nicotiflorin) 2, quercetin 3-O-β-glucoside 3, and luteolin 4 were isolated from the n-butanol layer of a methanolic extract of whole plants of Rh. stellatus of ...

Isoetin derivatives are a rare class of flavonoids with rather erratic occurrence across the plant kingdom. The Cichorieae tribe Asteraceae family has proven to be rich source and centre chemical diversity this compounds. Here, we describe chromatographic isolation mainly NMR-based structure elucidation previously undescribed isoetin derivative from Leontodon hispidus L. (Asteraceae, Cichorieae...

Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi....

Abstract As part of studies on South American Hieracium subg. Chionoracium, sect. Piloselliformia (Asteraceae: Cichorieae) in the present work are proposed four lectotypifications, one neotypification, and comments regarding previous nomenclatural decisions within group.
