Okra (Abelmoschus esculentus (L.) Moench), a healthy vegetable, is widely spread in tropical and subtropical areas. Previous studies have proven that okra pods possess anti-fatigue activity, and the aim of this research is to clarify the anti-fatigue constituents. To achieve this, we divided okra pods (OPD) into seeds (OSD) and skins (OSK), and compared the contents of total polysaccharides, to...

Kopasanda (Chromolaena odorata L.) is a plant that contains flavonoid compounds can act as antioxidants. This study aims to determine the antioxidant potential of ethanol extract stems, leaves and roots kopasanda by looking at IC50 value. The were extracted maceration using 70% solvent. results activity test FRAP (Ferric Reducing Antioxidant Power) method showed very strong with values ??of 23....

In this study, the antioxidant activity of the Convolvulus arvensis Linn (CA) ethanol extract has been evaluated by different ways. The antioxidant activity of the extract assessed by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation, the oxygen radical absorbance capacity (ORAC) and the ferric reducing antioxidant power (FRAP) was 1.62 mmol Trolox equivalents (TE)/g ...

Cornus species fruits are well known as a rich source of antioxidant compounds responsible for their diverse health benefits. The present study aims to investigate the variation of the total antioxidant capacity of Cornelian cherry (Cornus mas L.) fruits during storage, using high-performance thin-layer chromatography (HPTLC) and two spectrophotometric assays based on different mechanisms: the ...

This study was designed to examine the in vitro antioxidant activities of the essential oil and methanol extracts of rhizoma Alpinia officinarum (small galanga) from China. The essential oil was analyzed by gas chromatography/ mass spectrometry (GC/MS) and 46 constituents were identified. Methanol extract from rhizoma A. officinarum was fractionated by chromatography of silica gel using ethyl a...

Medicinal plants have a lot of type antioxidants, mostly polyphenols, flavonoids which exhibit high antioxidant activity (Rice-Evans et al. 1995). The intake of antioxidants present in food is an important health-protecting factor. Herbal compounds known by ancient medicine are of growing interest in the domain of prevention of diseases. The FRAP assay (ferric reducing ability of plasma), a sim...

chaetomorpha sp is one of the persian gulf green algae which can be a marine source of natural antioxidants such as polyphenols. industrial and economic development of these materials is influenced by effective extraction and application methods. microwave-assisted extraction (mae) and ultrasound-assisted extraction (uae) are novel techniques which have a potential to apply in laboratory with a...

BACKGROUND The emergence of drug resistant malaria is threatening our ability to treat and control malaria in the Southeast Asian region. There is an urgent need to develop novel and chemically diverse antimalarial drugs. This study aimed at evaluating the antimalarial and antioxidant potentials of Acacia nilotica plant extracts. METHODS The antioxidant activities of leaves, pods and bark ext...

Aim: Evaluation of effect shodhana process datura seed (Datura stramonium) antioxidant activity. Methods: The was purified with two different processes viz. cow’s urine, and milk by Dolayantra method. Antioxidant activity evaluated in-vitro 1,1-Diphenyl-2-picryl hydrazyl (DPPH) radicals scavenging Ferric reducing power ability (FRPA) assay. Result: cow urine (CUD) showed a significant in inhibi...

OBJECTIVE To investigate the antioxidant activities as well as phytochemical constituents of Antidesma thwaitesianum Müll. Arg. leaf extracts. METHODS The leaves of A. thwaitesianum were extracted using three different methods: blending with distilled water, maceration with ethanol and decoction. The chemical antioxidant activity of the plant leaf extracts was evaluated using 2,2-diphenyl-1-p...
