Red Lapacho (Tabebuia impetiginosa)—A global ethnopharmacological commodity?
Journal of Ethnopharmacology, 2009Red Lapacho (Tabebuia impetiginosa, syn. Tabebuia avellanedae), a canopy tree indigenous to the Amazonian rainforest and other parts of South America, has been acclaimed to be one of the "miraculous" cures for cancer and tumours. For the first time, during the 1960s, it attracted considerable attention in Brazil and Argentina as a 'wonder drug ...

Antibacterial activity of Tabebuia impetiginosa Martius ex DC (Taheebo) against Helicobacter pylori
Journal of Ethnopharmacology, 2006The growth-inhibiting activity of Tabebuia impetiginosa Martius ex DC dried inner bark-derived constituents against Helicobacter pylori ATCC 43504 was examined using paper disc diffusion and minimum inhibitory concentration (MIC) bioassays. The activity of the isolated compounds was compared to that of the commercially available anti-Helicobacter ...

Volatiles were isolated from the dried inner bark of Tabebuia impetiginosa using steam distillation under reduced pressure followed by continuous liquid-liquid extraction. The extract was analyzed by gas chromatography and gas chromatography-mass spectrometry. The major volatile constituents of T. impetiginosa were 4-methoxybenzaldehyde (52.84 microg/g)

Earlier work in our laboratory indicated that ethanolic extracts of Tabebuia impetiginosa, Arctium lappa L., Calendula officinalis, Helianthus annuus, Linum usitatissimum and L. propolis, inhibit pancreatic lipase in vitro. In a follow‐up study we assessed their effects on plasma triglycerides in rats fed on a fatty meal.

Cancer chemopreventive agent (S)-5-hydroxy-2-(1-hydroxyethyl)naphtho[2,3-b]furan-4,9-dione and its counterpart (R)-acetate have been obtained through a lipase-catalyzed transesterification process in organic solvent. Candida antarctica lipase B and Pseudomonas cepacia lipase have demonstrated their potential as excellent biocatalysts for the production

The acaricidal activity of a major constituent derived from the methanol extract of Tabebuia impetiginosa bark was compared with those of benzyl benzoate and abamectin using various bioassays against Dermatophagoides spp., Tetranychus urticae and Tyrophagus putrescentiae. The chloroform fraction obtained from the methanol extract of T.
