Anatomy, ultrastructure and secretion of Hibiscus pernambucensis Arruda (Malvaceae) extrafl oral nectary1
(Anatomy, ultrastructure and secretion of Hibiscus pernambucensis Arruda (Malvaceae) extrafl oral nectary). This paper reports on the extrafl oral nectary (EFN) of Hibiscus pernambucensis, a native shrub species occurring in mangrove and restinga along Brazil’s coastline.

متن کاملAntitumour Activity of Hibiscus tiliaceus Linn. Roots
The aim of this study was to evaluate antitumour activity of the roots of Hibiscus tiliaceus Linn. against Dalton’s Ascitic Lymphoma (DAL) in Swiss albino mice. A significant enhancement of mean survival time (MST) of H. tiliaceus treated tumour bearing mice was found with respect to control group. H. tiliaceus treatment was found to enhance peritoneal cell counts. When these H. ti...
متن کاملInhibition of intestinal motility by methanol extracts of Hibiscus sabdariffa L. (Malvaceae) in rats.
The methanol extracts of Hibiscus sabdariffa (p < 0.01) showed a significant dose dependent relaxant effect (IC50) = 350 microM) on rat ileal strip comparable to the effect shown by nifedipin and papaverine as reference compounds. Similarly, the extract when administered intraperitoneally significantly (p < 0.05-0.01) reduced the intestinal transit (13%-35%) in rats (IC50, = 250 microM). The ex...
