Quantitative HPLC Analysis of Sesquiterpene Lactones and Determination of Chemotypes in Eremanthus seidelii MacLeish & Schumacher (Asteraceae)
Eremanthus seidelii MacLeish & Schumacher tem ocorrência restrita ao cerrado, em torno do reservatório de Furnas (MG), em habitats que vêm sendo seriamente deteriorados pela ação humana. A presente investigação fitoquímica mostrou, como metabólitos secundários majoritários das folhas de E. seidelii, as lactonas sesquiterpênicas (LS) 4β,5-diidro-2’,3’-diidroxi-15-desoxigoiazensolídeo (1) e 4β,5-...

متن کاملChemical composition and biological activities of essential oils of Eremanthus erythropappus (DC) McLeisch (Asteraceae).
The chemical composition of the essential oils obtained by hydrodistillation of different parts of Eremanthus erythropappus, including leaves, branches and inflorescences, was investigated by Gas Chromatography and Gas Chromatography/Mass Spectrometry. The antimicrobial activity of the oils was assessed by the disc diffusion and microdilution methods, while the antioxidant activity was evaluate...
متن کاملExudate flavonoids in some Gnaphalieae and Inuleae (Asteraceae).
Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...
متن کاملThe flavonoids of Arnica frigida and A. louiseana (Asteraceae)
DOWNIE, S. R., and K. E. DENFORD. 1986. The flavonoids of Arnicafrigida and A. louiseana (Asteraceae). Can. J . Bot. 64: 2748-2752. Forty-six populations within the Arnicafrigida Meyer ex Iljin louiseana Farr complex were examined for flavonoid content. Seven glycosides were isolated and six identified. Members of this complex were found to produce primarily quercetin and kaempferol 3-O-glycosi...
