Stroke is the sudden blockage or rupture of cerebral arteries that can lead to cerebral damage or clinical neurologic deficit. Generally, stroke is as ischemic and hemorrhagic. Ischemia caused by factors such as thrombosis, embolism, and systemic hypoperfusion. Stroke is one of the most important factors of mortality and disability worldwide. After a stroke, an increase of free radicals has the most important role in the breakdown of blood-brain and increase of cerebral edema. This study aimed to review the effect of compounds isolated from plants to reduce cerebral ischemia. Our review showed that natural compounds could exert a protective effect by reduction of oxidative stress and events related to it. We also suggest that consider special attention to natural product for the treatment of cerebral...

The crude extract from the leaf of Canthium parviflorum Lam. in different solvents were subjected to physicochemical, fluorescence analysis, phytochemical and antimicrobial study. The microscopic analysis revealed that in C. parviflorum there is the presence of starch grains. The ash value was 5.81% in C. parviflorum. The fluorescent analysis at 366 nm of C. parviflorum powder extracted with alcohol showed orange-colored fluorescence with other it was no fluorescence. The extraction value with different solvents exhibited that C. parviflorum had maximum extractive value with chloroform followed by benzene, ethanol and petroleum ether. The phytochemical screening of the various extract of C. parviflorum revealed that the benzene extract showed the presence of alkaloids, tannins, flavonoids, saponins, and steroids. The chloroform extracts of the leaf showed the presence of alkaloids, tannins, flavonoids, saponins, and steroids. Anti-bacterial screening in C. parviflorum using stem revealed that the ethanol solvent showed maximum inhibition against gram-positive bacteria (Staphylococcus aureus) and chloroform solvent showed maximum inhibition in the case of gram-negative bacteria (Serratia...

Sulfated polysaccharides (SP) were extracted from Corallina officinalis marine red algae seaweed by using hydrothermal processes at 100 °C. The antioxidant activity of C. officinalis sulfated polysaccharide was determined using the (2,2-diphenyl-1-picrylhydrazyl, DPPH) method, showing that this polysaccharide has a moderate effect in inhibiting the formation of those radicals. This study demonstrates that sulfated polysaccharide obtained from marine red algae have the potential for use as natural antioxidants in industrial food...

This study aimed to utilize the phytoconstituents from medicinal plants; Carissa spinarum to generate herbal based antimicrobial and cosmetics to reduce the synthetic ingredients by incorporation of natural extracts whose functionality is comparable with their synthetic ingredients and compare its effectiveness with marketed antimicrobial and cosmetics products. The method used was the Soxhlet extraction to generate phytoconstituents, qualitative analysis of phytoconstituents for the presence of alkaloids, saponins, tannins and flavonoids, antimicrobial activity test by using disc diffusion sensitivity test. Three investigated herbal based shampoo formulations (F1, F2, and F3) were prepared by varying composition of Carrisa spinarum extracts and sodium laureth sulfate as a surfactant with a fixed amount of glycerine, EDTA and distilled water. F0 was containing all ingredients except Carissa spinarum extracts and was used as a negative control. Evaluation of physicochemical test including pH, solid content, wetting ability, foam volume and stability, and antimicrobial properties was conducted and compared to marketed shampoo. The result indicated that F2 and F3 produced clear shampoo and their averaged pH...

Leaves of ivy gourd; Coccinia grandis (L.) Voigt (Family: Cucurbitaceae) is one of the well-known leafy vegetables, which has been consumed by Sri Lankans for centuries. The therapeutic potential of ivy gourd against diabetes is brought mainly by its antihyperglycemic, β-cell regenerative, antihyperlipidemic and antioxidant properties. Also, the optimum effective therapeutic dose of the aqueous C. grandis extract was found to be safe in terms of hepatotoxicity, renotoxicity, hematotoxicity in-vivo. The scientific investigations confirmed the effectiveness of this leafy vegetable for the development of potential neutraceuticals against diabetes...
