Tabebuia aurea (Silva Manso) Benth. & Hook. f. ex S. Moore

Nota de alcance

PARTE UTILIZADA= Used part: Corteza.

ACCIÓN FARMACOLÓGICA= Pharmacological action: Amargo, antiperiódico (corteza).

COMPOSICIÓN QUÍMICA= Chemical composition: Flavonoids were isolated from Tabebuai caraiba by CC, PC, and Sephadex LH-20. The leaves yielded 6-hydroxyluteolin, luteolin-7-O-glucoside, quercetin-3-O-glucoside, quercetin-3-O-galactoside, rutin and a 3-O-diglycoside of quercetin based on galactose and rhamnose.

ZONA GEOGRÁFICA= Geografical zone: Brasil, Paraguay, NE de Argentina.

DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs

Microsatellite loci that were previously developed in the tropical tree Tabebuia aurea were used for the genetic analysis of Tabebuia roseo-alba populations. Nine of 10 simple sequence repeat markers were amplified, and the polymorphism was assessed in 58 individuals sampled from two stands in southeastern Brazil. All loci were polymorphic with Mendelian inheritance. The allele numbers were high, ranging from 5 to 13 in population I and 3 to 7 in population II, with means of 8.9 and 5.5, respectively. We conclude that these markers can be efficiently used for parentage and gene-flow studies. © 2009 The Authors.

ÚLTIMOS AVANCES EN LA QUÍMICA Y ACTIVIDADES BACTERIOLÓGICAS EN LAS PLANTAS MEDICINALES= Medicinal plants, last advances on chemistry and bacteria activities on the medicinal herbs

In this study, we report the development and characterization of 21 polymorphic microsatellite loci for Tabebuia aurea, using genomic library enrichment.  No. of alleles per locus and expected heterozygosity ranged from nine to 26 and from 0.808 to 0.955.  The high combined probability of genetic identity (1.03 ´ 10-37) and probability of paternity exclusion (0.9889) showed that multilocus genotypes are likely to be unique and will allow detailed parentage studies in natural populations of T. aurea.  Addnl., a high percentage of transferability was achieved for the four species of the same genus studied.

occurs in the Brasilean Cerrado. The plant is called paratodo which signifies 'for everything'. A decoction of the bark is used as an antipyretic, as an expectorant as well as for influenza and diarrhoea; it is also put on ulcers. The bark powder together with quinine is applied for the treatment of malaria, rheumatitis, lumbago, gout, sciatica, as well as for inflammations of the stomach and intestine.
