Farinose alpine Primula species: phytochemical and morphological investigations.
This work investigated the epicuticular and tissue flavonoids, the volatiles and the glandular trichome structure of the leaves of four species of Primula L. that grow in the Italian Eastern Alps. Primula albenensis Banfi and Ferlinghetti, P. auricula L., P. farinosa L., P. halleri Gmelin produce farinose exudates that are deposited on the leaf surface as filamentous crystalloids. In addition t...
متن کاملNovel 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 کاملIntegrating species distribution models (SDMs) and phylogeography for two species of Alpine Primula
The major intention of the present study was to investigate whether an approach combining the use of niche-based palaeodistribution modeling and phylo-geography would support or modify hypotheses about the Quaternary distributional history derived from phylogeographic methods alone. Our study system comprised two closely related species of Alpine Primula. We used species distribution models bas...
متن کاملPhytochemical, morphological, and biological investigations of propolis from Central Chile.
Propolis from central Chile was investigated for its plant origin by microscopical analysis of pollen grains and leaf fragments found in the sample. The pollen grains that appear with significant higher frequency in the sample corresponded to four native and two introduced species, whereas leaf fragments corresponded to four native species. Seventeen phenolic compounds that belong to the phenyl...
متن کاملPhytochemical Investigations on Four Galium Species (rubiaceae) from Romania
Galium species are used as diuretics, choleretics, against diarrhea and in the treatment of some stomach complaints, gout and epilepsy in folk medicine. Most of these species have been extensively investigated for antraquinones and iridoids but little is known about other bioactive compounds classes. Our research aimed to investigate the chemical composition of four Romanian species of Galium i...
