The occurrence of Physoclypeus farinosus Hendel in flowerheads of Asteraceae from different Brazilian localities is presented. The use of this resource by this fly is discussed.
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...
