Hibiscus sabdariffa L., roselle calyx, from ethnobotany to pharmacology.
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...
متن کاملHibiscus sabdariffa (Roselle) Extracts and Wine: Phytochemical Profile, Physicochemical Properties, and Carbohydrase Inhibition.
Three varieties of Hibiscus sabdariffa were analyzed for their phytochemical content and inhibitory potential on carbohydrate-digesting enzymes as a basis for selecting a variety for wine production. The dark red variety was chosen as it was highest in phenolic content and an aqueous extract partially inhibited α-glucosidase (maltase), with delphinidin 3-O-sambubioside, cyanidin 3-O-sambubiosid...
متن کاملResponses of Calyx Phytochemical Characteristic, Yield and Yield Components of Roselle (Hibiscus sabdariffa L.) to Different Sowing Dates and Densities
In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...
متن کاملHistological effects of roselle (Hibiscus sabdariffa L.) calyx in diets of albino rats
Roselle (Hibiscus sabdariffa) calyx was fermented traditionally and by controlled method with pure strains of Aspergillus flavus and Saccharomyces cerevisiae isolated from the fermentation. The proximate composition revealed that the sample fermented traditionally had the highest protein content of 14.7±2.5%. There was a significant decrease (Pd≤0.05) in the antinutrient content (phytate and ta...
متن کاملToxic Effects of Hibiscus Sabdariffa Calyx
The effects of a 90-day oral administration of water and alcohol extracts of dried calyx of Hibiscus sabdariffa were evaluated in albino rats. Haematological, biochemical and histopathological changes were monitored every 30 days. The death of the animals was preceded by a severe loss in weight, accompanied with diarrhoea in animals on the 2000 mg/kg dose. There was an increase in food intake (...
