Novel Compounds from the Farinose Exudate of Primula
In botany textbooks the farinose coating on leaves and inflorescences of many Primula species is still often said to "consist of flavone". We have shown earlier [1, 2] that it is in fact formed by varying amounts of unsubstituted flavone (at least 50%), 5-hydroxy flavone and 2'-hydroxy flavone, accompanied in many species by 5,8-dihydroxy flavone (primetin) and 5,2'-dihydroxyflavone. Further co...
متن کاملHplc Flavonoid Profiles of Bupleurum L. Species
A reliable solid-phase extraction – high-performance liquid chromatography (SPE-HPLC) method for the determination of flavonoids in European Bupleurum species B. baldense Turra and B. affine Sadler was developed. Extraction of aerial parts by ultrasound with 80% aqueous methanol and fractionation of flavonoids by means of SPE allowed a good recovery of analytes between 99 and 104%. The subseque...
متن کاملPrimula Culture and Production
The name Primula or primrose is derived from the word primary or first, referring to the early growth and flowering in spring (Liberty Hyde Bailey Hortorium, 1976). More than 400 species of primula exist in the family Primulaceae (Griffiths, 1994). Other important horticultural genera in this family, besides primula, include pimpernel (Anagallis), rock jasmine (Androsace), persian violet, alpin...
متن کاملExudate flavonoid aglycones in the alpine species of Achillea sect. Ptarmica: Chemosystematics of A. moschata and related species (Compositae-Anthemideae).
In completion of our studies on Achillea exudate flavonoids, 11 alpine species of Achillea sect. Ptarmica were analyzed for their aglycone profiles. The study focuses on species commonly associated with A. moschata. The major flavonoid constituents found in exudates of most taxa were 6-hydroxyflavonol 3,6,4'-trimethyl ethers, except in A. ageratifolia and its subspecies, which are characterized...
