BARBOSA, Wagner L. R.; SANTOS, Wallace R. A. dos; PINTO, Lucianna N.  e  TAVARES, Isabel C.C.. Flavonóides de Cissus verticillata e a atividade hipoglicemiante do chá de suas folhas. Rev. bras. farmacogn. [online]. 2002, vol.12, suppl.1, pp. 13-15. ISSN 0102-695X.  http://dx.doi.org/10.1590/S0102-695X2002000300007.

Cissus verticillata, a Vitaceae very used in the traditional medicine in Pará and Minas Gerais State - Brazil, was investigated in order to validate its indication for the hyperglycaemia control. The aqueous extract reduces the normal glycaemia of male white Wistar rats in about 19.5 %. The hypoglycaemic effect of this extract could be related to the flavonoids found in the preparation. Luteolin, Kaempferol and Luteolin-3'-sulphate could be isolated from the aqueous extract after acid hydrolysis.
