Carapanosins A-C from Seeds of Andiroba (Carapa guianensis, Meliaceae) and Their Effects on LPS-Activated NO Production.
Two new phragmalin-type limonoids, Carapanosins A and B (1 and 2), and a new gedunin-type limonoid, Carapansin C (3), together with five known limonoids (4-8) were isolated from the oil of Carapa guianensis AUBLET (Meliaceae) seeds, a traditional medicine in Brazil and Latin American countries. Their structures were elucidated on the basis of spectroscopic analyses using 1D and 2D NMR technique...
متن کاملDo Older Professional Musicians Have Cognitive Advantages?
The current study investigates whether long-term music training and practice are associated with enhancement of general cognitive abilities in late middle-aged to older adults. Professional musicians and non-musicians who were matched on age, education, vocabulary, and general health were compared on a near-transfer task involving auditory processing and on far-transfer tasks that measured spat...
متن کاملUptake of Seeds Secondary Metabolites by Virola surinamensis Seedlings
The major secondary metabolites and fatty acids occurring in the seeds of Virola surinamensis were monitored by GC-MS during germination and seedling development. The role as carbon source for seedling development was indicated considering that both classes of compounds were similarly consumed in the seeds and that no selective consumption of compounds could be detected.
متن کاملPollen and seed flow patterns of Carapa guianensis Aublet. (Meliaceae) in two types of Amazonian forest
Various factors affect spatial genetic structure in plant populations, including adult density and primary and secondary seed dispersal mechanisms. We evaluated pollen and seed dispersal distances and spatial genetic structure of Carapa guianensis Aublet. (Meliaceae) in occasionally inundated and terra firme forest environments that differed in tree densities and secondary seed dispersal agents...
متن کاملCarapanolides T-X from Carapa guianensis (Andiroba) Seeds.
Two new mexicanolide-type limonoids, carapanolides T-U (1-2), and three new phragmalin-type limonoids, carapanolides V-X (3-5), were isolated from the seeds of Carapa guianensis (andiroba). Their structures were determined on the basis of 1D- and 2D-NMR spectroscopy.
