BACKGROUND In this study, we suggested characterizing the vasodilator effects and the phytochemical characteristics of a plant with food usage also used in traditional treatment of arterial high blood pressure in Senegal. METHODS Vascular effects of crude extract of dried and powdered calyces of Hibiscus sabdariffa were evaluated on isolated thoracic aorta of male Wistar rats on organ chamber...

There is growing interest in the chemical composition of plants towards discovery of more effective biotherapeutic agents. Six bioactive compounds were evaluated from Hibiscus sabdariffa and Syzygium samarangense juice extracts. Both juices had high amounts of saponins, with Syzygium samarangense having higher content (4.77%) than Hibiscus sabdariffa (1.46%). Microbial counts in the juices were...

Previous findings on the capacity of Hibiscus sabdariffa (HS) polyphenols to ameliorate metabolic disturbances justify the necessity of studies oriented to find the potential metabolites responsible for such an effect. The present study examined the intestinal epithelial membrane permeability of polyphenols present in a phenolic-enriched Hibiscus sabdariffa extract (PEHS), free and encapsulated...

The root of Hibiscus syriacus (Malvaceae) has been used for treatment of fungal diseases such as tinea pedis (athlete's foot). In this study, we investigated the antifungal constituent of the root of Hibiscus syriacus Ggoma, which was produced by a mutation breeding using gamma ray irradiation, and compared the antifungal activity of H. syriacus Ggoma and its parent type. According to the resul...

Objective: To investigate the effect of the methanolic extract of Hibiscus rosa sinensis roots (H. sinensis) on the central nervous system in mice and rats. Materials and methods: The methanolic extract of H. sinensis was studied on pentobarbital-induced sleeping time, elevated plus maze, hole board test, foot shock-induced aggression, haloperidol-induced catalepsy, lithium-induced head twitche...

Hibiscus sabdariffa had been reported to have a broad range of therapeutic effects. The effects of oral administration of Hibiscus sabdariffa aqueous extract on some biochemical parameters were studied in wistar albino rats. A total of twenty five (25) male albino rats were grouped randomly into groups. Group A (control), Group B (0.6g/100ml of water of HS extract) Group C (1.2g/100ml HS extrac...

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...

In the present study, preliminary phytochemical screening using following Aegle marmelos (Bael), Annona squamosa (Sitaphal), Ficus racemosa (Gular), Hibiscus rosa sinenses (Jaswand) and Psidium guajava (Guava) five plant leaves extracts was done for the qualitative analysis of various phytochemical studies such as alkaloids, coumarins, saponins, flavonoids and steroids. . Aegle marmelos (leaves...

The phytochemical analyses, nutrient value and economic importance of Hibiscus sabdariffa commonly known as Zobo plant was carried out. In Nigeria the plant is used to make a popular beverage known as Zobo drink. Investigations revealed that the plant is highly rich in vital minerals and nutrients such as Iron, copper, calcium, magnesium, manganese required for healthy growth in humans. The phy...

The hypolipidemic activity of Hibiscus rosa sinensis (family Malvaceae) root extract was studied on triton and cholesterol-rich high fat diet (HFD) induced models of hyperlipidemia in rats. In triton WR-1339-induced hyperlipidemia, feeding with root extract (500 mg/kg body wt/day p.o.) exerted lipid-lowering effect, as assessed by reversal of plasma levels of total cholesterol (TC), phospholipi...
