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...

In this study, the forty Thai medicinal plants were used to screen the antibacterial activity against Campylobacter jejuni. Crude 95% ethanolic extracts of each plant were prepared. Antibacterial activity was investigated by the disc diffusion assay, and MICs and MBCs were determined by broth microdilution. The results of antibacterial screening showed that five plants have activity against C.j...

BACKGROUND Escherichia coli occurs naturally in the human gut; however, certain strains that can cause infections, are becoming resistant to antibiotics. Multidrug-resistant E. coli that produce extended-spectrum beta lactamases (ESBLs), such as the CTX-M enzymes, have emerged within the community setting as an important cause of urinary tract infections (UTIs) and bloodstream infections may be...

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...

Background and objectives: Hibiscus sabdariffa L. (roselle) sepals, commonly known as bissap is prepared as a cold drink which is widely drunk in Ghana and across West-Africa for their medicinal and nutritional properties. The plant is known to have anti-hypertensive, anti-hyperlipidemic, anticancer, anti-diabetic and anti-inflammatory activities. For such a widely sol...

Rosella flowers are able to provide a moisturizing and smoothing effect because they contain many substances that useful for the skin, rosella also synonymous with sour taste so it gives fresh sensation. In this study, ethanolic extract of used was at concentration 2%, 2.5%, 3%, 5%. This type research is experimental using pre-test post-test control group design. The sample flower lotion (Hibis...

Antioxidant and antihyperlipidemic activities of the extracts of leaves and calyces of Hibiscus sabdariffa were investigated by studying their in vitro inhibitory activity on lipid peroxidation and in vivo effects on cholesterol induced hyperlipidemia. Highest antioxidant activity was exhibited by ethanolic extract of calyces followed by ethanolic extract of leaves followed by aqueous extract o...
