The antioxidant actions of 80% ethanolic extract of dried flowers of Hibiscus sabdariffa L. (HSE) on lipid peroxidation (LPO), reduced glutathione (GSH), glutathione-s-transferase (GST), catalase (CAT), superoxide dismutase (SOD) and vitamin C (VITC), were examined using a model of sodium arsenite (SA) induced oxidative stress in rats. The oral administration of the extracts (200 and 300mg/kg b...

Spatially separated ecosystems are often linked by nutrient fluxes. Nutrient inputs may be transferred by physical vectors (i.e., wind and water) or by biotic vectors. In this study, we examine the role of green turtles (Chelonia mydas) as biotic transporters of nutrients from marine to terrestrial ecosystems, where they deposit eggs. We compare low and high nest density sites at Tortuguero, Co...

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...

AIM To determine the androgenic effects of Basella alba and Hibiscus macranthus extracts in the rat and the bull, and to develop a novel in vitro test system using Leydig cells from bull testes. METHODS The effect of methanol extracts from both plants on testosterone production in isolated Leydig cells from the rat and the bull was analyzed using 125I-radioimmunoassay (125I-RIA). Rat Leydig c...

As formas mais antigas para prevenção de doenças, tratamento e cura, estão na utilização das plantas medicinais. Dentre as várias espécies utilizadas pela população, encontra-se o Hibisco (Hibiscus sabdariffa). Pertencente à família botânica Malvaceae, é um arbusto anual, nativo dos continentes africano asiático, que se encontra distribuído nas regiões tropicais subtropicais ambos os hemisfério...

Background: Antihypertensive plants are one of the means of hypertension control. Objective: To examine the clinical antihypertensive efficacy and safety of the plants found in Iran. Methods: PUBMED, MEDLINE, SCOPUS, EMBASE, SCIENCEDIRECT, PROQUEST, OVID, EBSCO, GOOGLE, and GOOGLE SCHOLAR were searched. The PRISMA guideline was observed. The search terms were Iran, Iranian, plant, herb, antihyp...

Weeds pose major constraints in crop production. The use of allelochemicals and allelopathic species can provide an effective alternative for sustainable weed management. In a previous study that evaluated the activity wild cultivated plants Turkey, Hibiscus sabdariffa demonstrated strongest inhibitory potential. This aimed to estimate phytotoxic influence H. water crude extracts on Lactuca sat...

This study aimed to evaluate the antihypertensive efficacy of a new combination therapy of Hibiscus sabdariffa and Olea europaea extracts (2 : 1; Roselle-Olive), using N(G)-nitro-L-arginine-methyl ester- (L-NAME-) induced hypertensive model. Rats received L-NAME (50 mg/kg/day, orally) for 4 weeks. Concurrent treatment with Roselle-Olive (500, 250, and 125 mg/kg/day for 4 weeks) resulted in a do...

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...
