Research on the effect of processing on the retention of bioactive components with potential antioxidant activity is gaining importance. The objective of this investigation was to evaluate the effect of various processing methods (milling, boiling, pressure cooking, roasting and germination respectively) on the antioxidant components as well as the antioxidant activities in the commonly used pe...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

This study was to compare the relative level of antioxidant activity of methanolic extract of root bark of Berberis lycium Royle., in different test systems of antioxidant determination i.e ABTS (2,2’-azinobis-(3-ethyl-benzothiazoline-6-sulfonic acid) radical cation assay, Phosphomolybdenum assay and reducing power assay. In all these assays the antioxidant activity of extract was compared to t...

BACKGROUND Sida L., is a medicinally important genus, the species of which are widely used in traditional systems of medicine in India. Pharmacologically, roots are known for anti-tumor, anti-HIV, hepatoprotective, and many other properties. Phenolic antioxidants help in reducing oxidative stress occurring during treatment of such diseases. OBJECTIVE The study aimed to evaluate and compare po...

INTRODUCTION Calcium dobesilate is an antioxidant drug and this study is aimed to investigate the effects of calcium dobesilate on gentamicin-induced nephrotoxicity. MATERIAL AND METHODS This experimental study was conducted on 40 male Sprague-Dawley rats. The rats were randomly divided into the following 5 groups: control, sham, gentamicin (100 mg/kg/d, intraperitoneal), gentamicin and calci...

Hymenocallis littoralis has allelochemical importance such as defensive compounds, insect repellents, attractants, and their role in ecological balance. Antioxidant activities of Hymenocallis littoralis bulb, anther, flower, stem, leaves and root methanolic extracts were evaluated using Ferric Reducing Antioxdiant Power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH), total phenolic and flavonoid ...

the essential oils and aromatic water, known as arak in traditional iranian medicine, comes from the aerial part of teucrium persicum boiss., which is grown in fars province located in iran. the samples were collected in summer and the oils and aromatic water were obtained through steam distillation. the chemical composition of the oils was analyzed using gc-ms. an analysis of the chemical prof...

This study evaluated the antioxidant activity as well as bioflavonoid content of the methanol and ethanol-water extracts of the fresh and dried leaves of Tetracarpidium conophorum. Antioxidant activity was determined by spectrophotometric methods using DPPH free radical, nitric oxide radical inhibition and ferric reducing antioxidant power assays. In addition, total phenolics, flavonoids and pr...
