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...

The antioxidant activity of ethanolic seed extract of Hibiscus sabdariffa l. was investigated in toxicity induced by chronic administration of sodium nitrate in wistar rats. Twenty-five adult wistar rats were randomly grouped into 5 groups of five rats in each group (n=5). Group I (normal saline); Group II (25mg/kg NaNO3); Group III (25mg/kg NaNO3 + 10mg/kg vitamin C); Group IV (25mg/kg NaNO3 +...

The present study was undertaken to evaluate the medicinal properties of Hibiscus rosa sinensis on male mice. For this Swiss albino mice were orally administered Hibiscus rosa sinensis (500 mg/kg of body weight) and effect of the treatment on, reproductive organ cholesterol level and glucose level. Recovery study was also carried out. The treatment caused reduction in the weight of testis, epid...

The effect of aqueous extract of Hibiscus sabdariffa L. on the activity of alkaline phosphatase and uric acid in the liver of Rattus novergicus was studied in this research. The result from this study revealed that the activities of alkaline phosphatase in the serum slightly increased (18.00±3.39) when compared with that of the control (16.37±3.50) at (P<0.05) (Table. 1), though this was not st...

Wound healing agents support the natural healing process, reduce trauma and likelihood of secondary infections and hasten wound closure. The wound healing activities of water in oil cream of the methanol extract of Hibiscus sabdariffa L. (Malvaceae) was evaluated in rats with superficial skin excision wounds. Antibacterial activities against Pseudomonas aeroginosa, Staphylococcus aureus and Ech...

A new species of Eriophyidae (Acari: Prostigmata: E riophyoidea) mite, Aceria tripuraensis n. sp., is described from the closed bud galls of Hibiscus macrophyllus Roxb. ex Hornem. (Malvaceae) in India. Aceria tripuraensis n. sp. is distinguished by having a prodorsal shield with distinct rounded lobes on the postero-lateral margins and two pairs of submedian lines. The tarsal solenidia with unu...

The most part of hibiscus plants produces short life flowers that last one day. Therefore they are called ephemeral and flower senescence is usually associated with petal in-rolling and abscission. Flowers are well shaped and different organs can be easily separated, these characteristics make the hibiscus a good model system for flower senescence studies. The aim of this work was to identify m...

Hibiscus rosa-sinensis Linn. is one of medicinal plants in Indonesia that is used as a male contraceptive. Hibiscus flower contains flavonoids that can decrease testosterone. The purpose of this study was to determine the effects of hibiscus flower extract on the weight of the epididymis, prostate and seminal vesicles, and the thickness of the cauda epididymal epithelium, in male rats. 25 male ...

This study was aimed at establishing optimized conditions for hot water extraction of roselle beverage (soborodo) from its calyces as well as the degree of beverage sweetness in the commercial practice. The dried calyces/water ratios involved in the commercial practice ranged between 1:57 and 1:71 (w/v) while the sweetness level of the beverage ranged between 11.2 and 13.3 °Brix. The indices fo...
