Nephroprotective Effects of Aqueous Extracts of Hibiscus sabdariffa Calyces and Jatropha curcas Leaves against Lead Toxicity

Aqueous extracts of Hibiscus sabdariffa as antimicrobials in foods

Conversion of Sorrel (Hibiscus Sabdariffa) Calyces To Glucose

The utilization of agrowaste for the production of bioethanol has attracted worldwide attention as a strategy for reducing global warming and improving global energy security. Sorrel drink, popularly known as “zoborodo” in Nigeria is a non-alcoholic drink, which is obtained from the calyces of Hibiscus sabdariffa, by solid-liquid extraction process, leaving the calyces pulp as the raffinate. Th...

Toxicity studies of the water extract from the calyces of Hibiscus sabdariffa L. in rats.

Acute and chronic toxicities of the water extract from calyces of Hibiscus sabdariffa were studied in male and female rats. After 14 days of a single oral administration of test substance 5,000 mg/kg body weight, measurement of the body and organ weights, necropsy and health monitoring were performed. No signs and differences of the weights or behaviour compared to the control rats were observe...

Nootropic Activity of Calyces of Hibiscus Sabdariffa Linn

Nootropic acitivity of calyces of Hibiscus sabdariffa Linn. was studied in mice. Elevated plus maze and passive avoidance paradigm were employed to evaluate learning and memory parameters. Scopolamine (0.4 mg/kg, i.p.) was used to induce amnesia in mice. The aqueous extracts of calyces of Hibiscus sabdariffa (HS-100 and 200 mg/kg, p.o.) significantly attenuated amnestic deficits induced by scop...

Pharmacognostic Studies of the Jatropha Curcas Leaves

The J. curcas is considered as a biofuel plant, but the leaves are traditionally used as an antiinflammatory and anticoagulant. In present investigation, the detailed pharmacognostic study of J. curcas leaf is carried out to lay down the standards which could be useful in future experimental studies. The study includes macroscopy, microscopy, preliminary phytochemical screening and physicochemi...
