Using MEDLINE and SCOPUS databases, a review of the literature from the pioneering study of 1991 until 2010 was performed on the effects on biological models of Hibiscus sabdariffa L. roselle calyx, its extracts mainly in polar solvents, or pure components found in extracts, as well as their possible relationship to these effects. Three relevant effects on lipid metabolism, antihypertensive act...

objective: antibiotic resistant to antimicrobial agent is one of the most important concern in hospitals, which can cause lots of costs, treatment fails and mortality rates. acinetobacter baumannii is a gram-negative bacterial pathogen notorious for causing serious nosocomial infections that resist antibiotic therapy. the purpose of current study was to define the evolution of antimicrobial imp...

Coat protein (CP) of Hibiscus chlorotic ringspot virus (HCRSV) had been found to be responsible for the spread of infection. Kenaf (Hibiscus cannabinus) was used as a model organism in this study. As CP is most likely localized in the peroxisomes, there is a need to produce a protocol adapted solely for the isolation of peroxisomes from the leaf of Kenaf as peroxisomal characteristics differ gr...

There is growing interest in the chemical composition of plants towards discovery of more effective biotherapeutic agents. Six bioactive compounds were evaluated from Hibiscus sabdariffa and Syzygium samarangense juice extracts. Both juices had high amounts of saponins, with Syzygium samarangense having higher content (4.77%) than Hibiscus sabdariffa (1.46%). Microbial counts in the juices were...

The antioxidant activity of ethanolic seed extract of Hibiscus sabdariffa l. was investigated in toxicity induced by chronic administration of sodium nitrate in wistar rats. Twenty-five adult wistar rats were randomly grouped into 5 groups of five rats in each group (n=5). Group I (normal saline); Group II (25mg/kg NaNO3); Group III (25mg/kg NaNO3 + 10mg/kg vitamin C); Group IV (25mg/kg NaNO3 +...

The present study was undertaken to evaluate the medicinal properties of Hibiscus rosa sinensis on male mice. For this Swiss albino mice were orally administered Hibiscus rosa sinensis (500 mg/kg of body weight) and effect of the treatment on, reproductive organ cholesterol level and glucose level. Recovery study was also carried out. The treatment caused reduction in the weight of testis, epid...

In this work, we develop the synthesis of selenium nanoparticles (B@SeNPs) using a green method aqueous extract Hibiscus esculentus L. Various techniques were used to characterize bio-synthesized B@SeNPs. The mixture color was clearly changed reddish at 45-50 °C and pH = 6. According Fourier transform infrared spectroscopy (FT-IR), B@SeNPs produced, capped, stabilized biomolecules found in plan...

The effect of aqueous extract of Hibiscus sabdariffa L. on the activity of alkaline phosphatase and uric acid in the liver of Rattus novergicus was studied in this research. The result from this study revealed that the activities of alkaline phosphatase in the serum slightly increased (18.00±3.39) when compared with that of the control (16.37±3.50) at (P<0.05) (Table. 1), though this was not st...
