Plants possess good antioxidant capacity to get rid of free radicals that cause many lifestyle diseases especially cancer. Assessment of Antioxidant activity of Amaranthus Linn. leaves were evaluated by using in- vitro model. In the present study evaluation of ethyl acetate of extract of Amaranthus Linn. leaves with the help of two In-vitro antioxidant models were carried out for Nitric-oxide scavenging Activity and DPPH method. IC50 value was calculated and compared with standard Ascorbic acid. Ethyl acetate extract was found to be extremely effective in scavenging nitric-oxide (IC50 584.4 μg/ml to 1072 μg/ml). In inhibition of DPPH Radical Scavenging activity (IC50 260.6 μg/ml to 957 μg/ml). Ethyl acetate extract showed different levels of antioxidant activities in tested...

The alcoholic extract of fruits of the plant Luffa acutangula previously reported for is hepatoprotective activity was fractionated into three parts to chemically identify the most potent bioactive fraction. The hepatoprotective potential of the fraction prepared from extract was studied in vivo in rats as well as ex vivo in isolated hepatocytes against paracetamol induced hepatotoxicity. The hepatoprotective activity was determined on the basis of their effects on parameters like direct bilirubin, serum aspartate transaminase, serum alanine transaminase and alakaline phasphatase. Ethyl acetate fraction (EAF) of alcoholic extract 100 mg/kg, p.o.) exhibited maximum hepatoprotective activity and is the active fraction for hepatoprotective activity of L. acutangula...

Cinnamomum riparium Gamble belongs to the family Lauraceae is a red listed species by the International Union for Conservation of Nature (IUCN). It is a tree growing in evergreen forests and traditionally used for treating conditions like wound healing, fever, intestinal worms, headache, inflammations, menstrual problems etc. According to tribal’s, this activity is mainly due to the volatile oil present in it. But as per published reports much works have not been carried out so far using its volatile oil. Hence it was thought worth to do the research work on this plant. Berries were collected from Paniyeli poru, near Periyar river, Ernakulam District, latitude 10.1720° N and longitude76.5959° E Kerala, India. Berry essential oil was separated by steam distillation technique by using a Clevenger trap apparatus. Separated berry essential oil was used for evaluating the physical and chemical properties including therapeutic activity (antioxidant activity) using DPPH scavenging assays. The berry oil exhibited 76.45% of antioxidant activity. The oil was subjected to GC-MS analysis. The main constituents present in...

Diclofenac sodium is a nonsteroidal anti-inflammatory drug (NSAIDs) with analgesic and antipyretic properties. Because of widespread use of this drug, quality control testing should be done for diclofenac marketed products to ensure safety; efficacy; accepted quality; rationality of use to protect public health. Quality of pharmaceuticals has been great concern of WHO. Drug cost needs to be reduced as health care costs continue to rise. Generic products need to be therapeutically equivalent to the brand innovator products. This can be achieved only when bioequivalent study is conducted to show whether a generic product is interchangeable with brand product or another generic product. In this study focus is given to evaluate and compare the quality of six different brands of enteric coated diclofenac sodium tablets marketed in Addis Ababa and also to study the different physicochemical properties of diclofenac sodium enteric coated tablets and to compare in vitro dissolution profile of six brands of diclofenac sodium delayed release...

Agapanthus praecox Willd of the family Amaryllidaceae is widely used in South African traditional medicine to treat heart disease, paralysis, coughs, colds, chest pains and diarrhoea. The decoction is used to prevent pregnancy complications and argument labour. The study aims at determining the phytochemical constituents and investigating the potential toxicity of the solvent extracts of A. praecox. Quantitative phytochemical analysis was done using standard procedures and spectro-photometric techniques while the toxicity assessment was carried out with brine shrimp toxicity bioassay. The data were subjected to two way analysis of variance (ANOVA) followed by Tukey’s test. Methanol had the highest percentage yield of extract (16.2 %) while water (9.3 %) was the least. The quantities of tannins (335.23 mg g-1), phenols (91.11 mg g-1), proanthocyanidins (139.47 mg g-1), flavonoids (46.53 mg g-1) and flavanols (74.02 mg g-1) in acetone extract were significantly higher (p > 0.05) than in aqueous and methanolic extracts. Highest hatching success was recorded in aqueous extract (50.33%) and the lowest hatching success (p < 0.05) was...
