Crystal structures of hibiscus acid and hibiscus acid dimethyl ester isolated from Hibiscus sabdariffa (Malvaceae)
The biologically active title compounds have been isolated from Hibiscus sabdariffa plants, hibiscus acid as a dimethyl sulfoxide monosolvate [systematic name: (2S,3R)-3-hy-droxy-5-oxo-2,3,4,5-tetra-hydro-furan-2,3-di-carb-oxy-lic acid dimethyl sulfoxide monosolvate], C6H6O7·C2H6OS, (I), and hibiscus acid dimethyl ester [systematic name: dimethyl (2S,3R)-3-hy-droxy-5-oxo-2,3,4,5-tetra-hydro-fur...
متن کاملParalogy and orthology in the MALVACEAE rpb2 gene family: investigation of gene duplication in hibiscus.
A sample of the second largest subunit of low-copy nuclear RNA polymerase II (rpb2) sequences from Malvaceae subfamily Malvoideae suggests that rpb2 has been duplicated early in the subfamily's history. Hibiscus and related taxa possess two rpb2 genes, both of which produce congruent phylogenetic patterns that are largely concordant with cpDNA topologies. No evidence of functional divergence or...
متن کاملImmunomodulatory effect of extracts of Hibiscus sabdariffa L. (Family Malvaceae) in a mouse model.
The immunomodulatory activity of water and alcohol extracts (including its fractions) of the dried calyx of the plant was evaluated in mice. The ability of the extracts to inhibit or enhance the production of two cytokines, namely tumor necrosis factor-alpha (TNF- alpha) and interleukin-10 (IL-10), respectively, implicated as proinflammatory and antiinflammatory interleukins were also evaluated...
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...
متن کاملToxicity and immunomodulatory activity of fractions of Hibiscus sabdariffa Linn (family Malvaceae) in animal models.
This study evaluated immunomodulatory properties and the sub-acute toxicity profile of two fractions of the aqueous alcoholic extract of the dried calyx of Hibiscus sabdariffa in experimental animals. Immunomodulatory activity was evaluated using red blood cell-induced immunostimulation. The fractions were not found to be toxic after 7-day administration, though there was severe weight loss wit...
