Phytochemical analysis of Cymbopogon citratus revealed presence of bioactive compounds such as alkaloids, flavonoids, saponins, tannins, phenols, terpenoids etc. Each of the bioactive compounds were estimated and isolated separately by solventsolvent extraction for methanolic and aqueous extracts of Cymbopogon citratus. Saponins content was higher in methanolic extracts of Cymbopogon citratus (...

Antioxidant potential of various extracts of Cassia fistula was determined by the DPPH, FRAP, Fe(3+) reducing power, and hydrogen peroxide scavenging assay. Methanolic extracts of Cassia fistula showed the highest amount of phenolic and flavonoid content and reducing capacity, whereas hexane extracts exhibited the lowest level of reducing capacity. The order of antioxidant activity in Cassia fi...

PURPOSE This study is aimed at determining chemical constituents and antimicrobial activities of a common brand of black tea (Lipton®) in Nigeria. METHOD Standard methods were employed for testing carbohydrates, tannins, saponins, flavonoids, alkaloids, steroids and terpenes in the tea. Antimicrobial activities of methanolic and aqueous extracts of the tea on four standard strains of organism...

In vitro antibacterial activities of hexane, chloroform and methanolic crude extracts of Abrus precatorius seeds were tested against ten clinical isolates using the agar well diffusion technique. Hexane, chloroform and methanolic extracts were obtained using the soxhlet extractor on A. precatorius seeds. To measure the MIC values, various concentrations of the stock, 500, 250, 100, 75, 50, 35, ...

The antifungal efficacy of seed extracts (propanol, ethanol, methanol and sterile deionised water) of Camelina sativa cv. Calena (EC643910) against Rhizopus stolonifer was investigated by agar disc diffusion method. Among all extracts, methanolic seed extract (Disc 3) showed significant activity against R. stolonifer. However, no activity was observed against rest of the extracts (Disc 1, 2 and...

Chemical composition and antibacterial activity of aqueous (ethanolic and methanolic) extracts from herbs often used in Polish cuisine and traditional herbal medicine including thyme (Thymus vulgaris L.), rosemary (Rosmarinus officinalis L.), oregano (Origanum vulgare L.), peppermint (Mentha piperita L.) and sage (Salvia officinalis L.) were compared. The aqueous ethanolic extracts contained sl...

the aim of this study was to investigate the stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. the volatile constituents from the aerial parts of stachys turcomanica growing wild in iran were obtained by hydrodistillation and analyzed by gc and gc-ms. in the gc-ms analysis, forty-six components representing 81.1% of the oil were identifie...

The present investigation to evaluate the antioxidant activities of various extracts of whole plant of Borreria hispida (Linn) in different invitro methods. The antioxidant activity was evaluated by Total antioxidant activity (Phosphomolybdic acid method), FRAP assay with reference standard Ascorbate and total phenol content respectively. The methanolic extract of Borreria hispida was the most ...

PURPOSE This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects. METHODS DPPH assay and agar well diffusion method were carried out to determine antioxidant and antimicrobial activities respectively. RESULTS Methanolic extract showed better antioxidant...

The present study was carried out to evaluate the antidiabetic activity of Vinca rosea methanolic whole plant extracts in alloxan induced diabetic rats for 14 days. The methanolic whole plant extract at high dose (500 mg/kg) exhibited significant anti-hyperglycemic activity than whole plant extract at low dose (300 mg/kg) in diabetic rats. The methanolic extracts also showed improvement in para...
