Structure of arboreal and herbaceous strata in a neotropical seasonally flooded monodominant savanna of Tabebuia aurea.
Large areas in the Pantanal wetland are covered by monodominant formations, e.g. typical landscapes with local names such as "paratudal", dominated by T. aurea. Studies on structure of these formations generally include only woody strata, consequently the species richness registered is usually low due to the absence of the 'ground layer' of herbaceous and others low species. We recorded 13 spec...
متن کاملBioactive phenylpropanoid glycosides from Tabebuia avellanedae.
Three novel phenylpropanoid glycosides 2, 5, 6 were isolated from water extract of Tabebuia avellanedae, together with three known phenylpropanoid glycosides 1, 3, 4. All compounds were identified on the basis of spectroscopic analysis and chemical methods and, for known compounds, by comparison with published data. All isolated compounds showed strong antioxidant activity in the DPPH assay, an...
متن کاملMicellar electrokinetic chromatography (MEKC) separation of furanonaphthoquinones from Tabebuia impetiginosa.
The separation of nine furanonaphthoquinones by micellar electrokinetic chromatography (MEKC) is described. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.09 M borate buffer (pH 9) containing 10% methanol, with an applied voltage of 20 kV. Application of this technique in the determination of the main furanonaphthoquinones, 5-hydroxy-2-(1-hydroxyethy...
متن کاملOccupational asthma caused by Ipe (Tabebuia spp) dust.
BACKGROUND Ipe is a resistant hardwood that contains naphtoquinones. It is easily found and frequently used in South and Central America. Naphtoquinones are skin sensitizers. OBJECTIVE To describe a case of occupational asthma related to Ipe wood dust. METHODS The patient was submitted to a clinical evaluation consisting of a respiratory symptom questionnaire, occupational history, serial m...
متن کاملIridoid Esters from Tabebuia avellanedae and Their In Vitro Anti-inflammatory Activities.
A phytochemical investigation of the inner bark of Tabebuia avellanedae Lorentz ex Griseb was carried out by various chromatographic techniques, resulting in the isolation and characterization of eight new iridoid esters, namely Avelladoids A-H (1-8). Their chemical structures were elucidated on the basis of extensive spectroscopic analyses, especially 2D NMR experiments and HRMS data. The anti...
