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...

The present study was aimed to find out the antimicrobial potential of acetone extract of Acacia concinna leaf against five different bacterial strains at 100 and 200mg/ml concentrations. The disc diffusion assay was performed to access the antimicrobial potential of the extract. The agar plate containing a bacterial culture was divided into 4 zones, and each zone was independently impregnated with four sterile filter paper discs (6 mm in diameter) containing (10 µl of each concentration) distill water (Negative control), ampicillin (Positive control); Acacia concinna leaf extract (100 mg/ml and 200 mg/ml as test). Zone of inhibition and MIC (minimum inhibitory concentration) for test drug was evaluated to access the antimicrobial potency. The phytochemical analysis shows the presence of alkaloids, tannins, and glycosides that might be responsible for the aimed biological activities. Out of five bacterial strains, the test drug exhibit zone of inhibition against Mycobacterium smegmatis and Bacillus subtilis in a concentration-dependent manner. Minimum inhibitory concentration (MIC) of test drug against Mycobacterium smegmatis and Bacillus subtilis, was found...

To access the quality of drug the standardization is very critical. As per WHO guidelines, 80% of the peoples have relied on traditional medicine in a rising nation. Most of the conventional system is valuable but a lack of standardization. The parameters studied are physicochemical parameters, phytochemical parameters & qualitative chemical tests. These values will help to obtain the batch to batch variation in traditional preparation of Mehari Choorna which is used to treat diabetes mellitus. We calculated and discussed extractive values, moisture content and ash value. The scientific method for its quality and safety evaluation is not yet to be documented. Hence in the current work, an attempt has been made to evaluate the quality parameters to be used for its preparation and...
