Resumen

MURILLO, Elizabeth; LOMBO, Oscar; TIQUE, Margarita  y  MENDEZ, Jonh J. Antioxidant Potential of Bauhinia Kalbreyeri Harms (FABACEAE). Inf. tecnol. [online]. 2007, vol.18, n.6, pp.65-74. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000600009.

Antioxidant activity of aqueous and organics extracts from the leaf and bark of Bauhinia kalbreyeri Harms it is describes, this plant has been determined by the Colombian ethnomedicine as antidiabetic. The extracts were evaluated for their free radical scavenging activity by DPPH method. Ethanol an aqueous extracts showed the higher DPPH radical scavenging activity than 90% in almost all the concentration tested (5-120 mg/ml), the efficient concentrations were low, supported the high inhibitory potential. The reducing power reveled dependence on the extractor solvent and the use of leaf or bark, but independent from the concentration; ethanolic extract of bark exhibited a high reductive potential. Ethanolic and aqueous extracts of bark showed greatest phenols amount. The plant can be considered as a good source of natural antioxidants,  that could  resist the excess of free radicals, hence exert the therapeutic properties attributed, more than act  as a hypoglycaemic.

Palabras clave : Bauhinia kalbreyeri; antioxidant activity; DPPH method; free radicals; reducing power.
