“…As with lapachol and ␤-lapachone, the other occurring compounds found in Tabebuia impetiginosa are the naphto[2,3-b]furan-4,9-diones (furanonaphtaquinone) and anthracene-9,10-diones (anthraquinones) (Steinert et al, 1995;Steinert and Rimpler, 1996). Some of these are shown in Fig.…”

“…Hussain et al (1990) verifi caram a presença de terpenóides e polifenóis. Aloe vera L. (Babosa) -A babosa tem ação cicatrizante, antibacteriana, antifúngica e antivirótica pela presença das antraquinonas como aloenina, barbaloína e isobarbaloína em sua composição química (Kuzuya et al, 2001;Steinert et al, 1996). Tais propriedades justifi cam seu uso popular, mas por causa da sua ação nefrotóxica em doses altas, não deve ser usada como lambedor, pois nessa preparação o teor de seu princípio predominante é aumentado e pode causar severa crise de nefrite aguda (Matos, 2000).…”

RESUMO:Este trabalho apresenta um levantamento das plantas medicinais utilizadas pelos índios Tapebas do Ceará, na tentativa de resgatar a cultura descaracterizada ao longo dos anos. Os parâmetros considerados foram a freqüência de uso das plantas e suas indicações populares para determinadas doenças, baseando-se em entrevistas realizadas nas comunidades localizadas no município de Caucaia, situado a 16 Km de Fortaleza, capital do Ceará, em que foram mencionadas 63 plantas. Amostras das plantas foram coletadas e depositadas no Herbário Prisco Bezerra da Universidade Estadual do Ceará, onde foram identifi cadas. As plantas mais citadas foram agrupadas de acordo com seus dados químico, farmacológico e/ou toxicológico encontrados na literatura científi ca. A pesquisa mostra que a comunidade indígena dos Tapebas faz uso de muitas espécies vegetais sem dados químico e farmacológico registrados, bem como de outras que já foram alvo de pesquisa científi ca, mas que necessitam ainda de estudos complementares para garantir segurança para um uso geral e preparação de fi toterápicos.Unitermos: Plantas medicinais, índios, Tapebas, Ceará. ABSTRACT: "Ethno-medicinal plants of Tapeba Indians from the State of Ceará -Brazil".This work presents a survey of the medicinal plants used by Tapebas Indians from the state of Ceará -Brazil, trying to rescue their culture which is vanishing through the years. Several interviews were performed at the indian's community located at municipality of Caucaia, 16 Km away from Fortaleza, Capital city of the state of Ceará. A total of 63 plants were cited. The interviews were based on the frequency that the plants are used and their respective uses. Samples of the plants were collected and classifi ed by botanists of the Prisco Bezerra Herbarium of the Universidade Federal do Ceará. A literature survey was carried out with all known plants to obtain chemical, pharmacological and toxicological informations. The results show that the Tapebas use plants with no reported chemical and pharmacological informations and other plants which were already studied but need yet more studies to assure complete safety for a general use and production of phytoterapics.

“…On the other hand, Red Lapacho herbal tea made from the bark of the plant Tabebuia impetiginosa contains compounds such as lapachol and beta-lapachone and iridoid glycosides, lignan glycosides, isocoumarin glycosides, phenylethanoid glycosides, and phenolic glycosides (Steinert et al 1996;Warashina et al 2004). There is a lack of information about phenolic acids in that plant.…”

Optimization of the extraction process of green tea using response surface methodology (RSM) was performed. The optimized conditions were 14.91 min and 94.15°C (2,2-diphenyl-1-picrylhydrazyl (DPPH) assay). The experimental values were close with the predicted values. The procedure was used to measure antioxidant activity using DPPH free radical and phenolic compounds of all types of Camellia sinensis and Tabebuia impetiginosa infusions. The antioxidant activity of infusions was in the order (mean for analyzed types) of pure green tea > white tea > green tea with additives > black tea = Pu-erh tea > semifermented tea > Red Lapacho. After the fermentation process, the content of rutin is lowered and the amount of gallic acid in infusions is increased. A negative correlation between total phenolic acids and organic acids was also observed (R 2 =0.6437). Red Lapacho infusion contains phenolic acids such as caffeic, protocatechuic, pcoumaric, ferulic, and syringic. No rutin and quercetin were found in this beverage.
