Hibiscus mealybug, Maconellicoccus hirsutus (Hemiptera: Pseudococcidae), is the major pest of many vegetables, fruits, crops, and ornamental plants causing losses to the farmers and its control has been an issue of significance in the pest management. This study was aimed at evaluating different concentrations (0.06%, 0.1%, and 0.14%) of Telsta, Advantage, Talstar, Imidacloprid, and their mixtu...

The effect of Hibiscus sabdariffa L. (Hs) calyx extract on fat absorption-excretion and body weight in rats, was investigated. Rats were fed with either a basal diet (SDC = Control diet) or the same diet supplemented with Hs extracts at 5%, 10% and 15% (SD(5), SD(10) and SD(15)). Only SD(5) did not show significant increases in weight, food consumption and efficiency compared to SD(C). The oppo...

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...

Hibiscus cannabinus, Cannabis sativa, and Hibiscus sabdariffa, fast growing productive annual plants, could provide fiber necessary to partially alleviate the world’s fiber deficit. The present study aimed at producing high yield pulp and the best mechanical strength properties with minimum impact on environment by SAS-AQ, and NSSC-AQ pulping processes. A total alkali of 13% (as Na2O), an alkal...

ETHNOPHARMACOLOGICAL RELEVANCE The roots of Hibiscus vitifolius Linn. (Malvaceae) is used for the treatment of jaundice in the folklore system of medicine in India. This study is an attempt to evaluate the hepatoprotective activity of the roots of Hibiscus vitifolius against anti-tubercular drug induced hepatotoxicity. MATERIALS AND METHODS Hepatotoxicity was induced in albino rats of either ...

The discovery of bioactive compounds in foods has changed the dietary lifestyle of many people. Cyperus esculentus (tigernut) is highly underutilized in Africa, yet tigernut extract is highly profitable in Europe. This study aims to add value to tigernut extract by revealing its health benefits and food value. In this study, tigernut tubers were germinated or roasted and the extracts were combi...

A sequential solvent extraction scheme was employed for the extraction of antioxidant compounds from kenaf (Hibiscus cannabinus L.) seeds. Yield of extracts varied widely among the solvents and was the highest for hexane extract (16.6% based on dry weight basis), while water extract exhibited the highest total phenolic content (18.78 mg GAE/g extract), total flavonoid content (2.49 mg RE/g ext...

Wong Y.-H., Tan Ch.-P., Long K., Nyam K.-L. (2014): In vitro simulated digestion on the biostability of Hibiscus cannabinus L. seed extract. Czech J. Food Sci., 32: 177–181. We investigate the biostability of phenolic acids from a kenaf (Hibiscus cannabinus L.) seed extract using an in vitro model simulating the physicochemical (pH, temperature and bile salts) and biological (gastric and pancre...

Hibiscus rosasinensis flowers and leaves are available all over India and well known for its Antidiabetic property. In the present investigation aqueous extract and ethanolic extract of the flowers and leaves were made using soxhlet apparatus, water extract and maceration. The qualitative Phytochemical screening procedure was performed on each extract. Phytochemical study reveals that alkaloids...
