—Seed predation has the potential to strongly reduce seed production and thereby act as a selective force on the evolution of flowering traits and other defenses against herbivory. We characterized levels of predispersal seed predation on Hibiscus moscheutos (Malvaceae) during 2001 and 2002 at four sites in Ohio and Maryland, USA. The seed predators were a weevil, Conotrachelus fissinguis (Cole...

The present study is designed to investigate the hypolipidemic effect of ethanolic extract from the leaves of Hibiscus sabdariffa L. (HSEE) in hyperlipidemic rats. In the present work, HSEE was evaluated at three doses (i.e. 100, 200 and 300 mg/kg, orally) in cholesterol-induced (2 g/kg, orally) hyperlipidemic Wistar rats. Atorvastatin (10 mg/kg, orally) was used as the standard drug. Administr...

effect of adding hibiscus sabdariffa (hs) in diet on performance and immune response of broilers was examined during aflatoxicosis using a total of 192 day-old ross 308 male chicks in a completely randomized design with four treatments, four replicates and 12 chicks per each replicate. treatments were include: 1. negative control (without additives), 2. positive control (2.5 mg aflatoxin b1/kg)...

Hibiscus tiliaceus, locally known as Bhola was examined for phytochemical properties and its cytotoxic, antibacterial, analgesic and neuropharmacological activities using the ethanol extract of leaf and bark. The phytochemical analysis of the leaf extract indicated the presence of tannins, whereas bark extract indicated the presence of alkaloid, reducing sugar and tannins. A preliminary cytotox...

Background: The flowers, calyx and seeds of Hibiscus sabdariffa L. (Malvaceae) are used in traditional medicine for management of edema, cancer, constipation, hypertension, fever, liver and nerve diseases. In Nigeria, a decoction of the seeds is used in folk medicine to enhance or induce lactation in cases of poor milk production. But its potential for toxicity when administered during pregnanc...

BACKGROUND Hibiscus tiliaceus L. (Malvaceae) is used in postpartum disorders. Our purpose was to examine the antidepressant, anxiolytic and sedative actions of the methanol extract of H. tiliaceus flowers using animal models. METHODS Adult male Swiss albino mice were treated with saline, standard drugs or methanol extract of H. tiliaceus and then subjected to behavioral tests. The forced swim...

The aim of this study was to evaluate the phenolic and flavonoids contents and the antioxidant and antitumoral activity of leaf and calyx methanolic extracts from Hibiscus sabdariffa (roselle) cultivated with poultry litter and organosuper® under three modes of application. The total phenolic content in the each extract was determined using the Folin-Ciocalteu reagent and for aluminium chloride...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
