Phytochemical investigations of Taxus baccata L. by successive chromatographic methods resulted in the isolation of the lignans lariciresinol (1), taxiresinol (2), 3'-demethylisolariciresinol-9'-hydroxyisopropylether (3), isolariciresinol (4), and 3-demethylisolariciresinol (5) as well as taxoids. Compounds 1-5 were evaluated for their acetylcholinesterase (AChE), butyrylcholinesterase (BChE), ...

(nyctaginaceae) is a medicinal plant used for the treatment of kidney disorders, urinary tract disorders and blood purification in baluch tribe. the aim of present study is to evaluate the antioxidant propertyof b. elegans species for the first time. materials and methods: different parts (leaf, stem and fruit) of the plant were extracted by using various solven...

Piper chaba Hunter, a flowering vine of Piperaceae family, has been using for long time in south Asian country for culinary meat preparation. As stem and root of this plant has been using traditionally in fat rich meat preparation, the antioxidant and anticoagulation potential of this herb is a great interest of study and it was evaluated using cold and boiled water extract of dried and grinded...

the present work is carried out to study the antioxidant potential of ethanolic extract of alstonia scholaris linn. ( apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (dpph . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   ethanolic extract of alstonia...

Background: This study was devoted to assessing the inhibitory potential of acetone, methanol, and ethanol extracts of Acroptilon repens against disease-associated enzymes, as well as their antioxidant/antibacterial activity and phytochemical composition. Methods: Comparative assessment using various antioxidant evaluation methods, including ferric reducing antioxidant power, scavenging ability...

Plant foods are important due to their antioxidant activity (AOA) attributed to the phenolics which are known to protect organisms against harmful effects of oxygen radicals. However, information on antioxidant activity of Indian plant foods is scanty. Therefore, the present study evaluated the AOA of cereals, millets, pulses and legumes, commonly consumed in India and assessed the relationship...

INTRODUCTION Reperfusion injury leads to damage to the hemodynamic and functional parameters of the kidney. This study investigated the effects of oral administration of the aqueous extract of rosemary on improvement of changes induced by ischemia-reperfusion in rats. MATERIALS AND METHODS Fourty male Sprague-Dawley rats were divided into 4 groups. One group was the control, rates in another ...

Thirty samples from thirteen Sicilian monofloral honeys by the local black honeybee, and two honeydew honeys, were studied to assess phenol content, reducing power and antioxidant capacity as well as correlations among these parameters. Honeys from Apiaceae showed the highest phenol amount and capacity to reduce ferric ion and stable chemical radicals, whereas honeys from Leguminosae the lowest...

BACKGROUND Alzheimer's disease (AD) is a progressively developing neurodegenerative disorder of the brain in the elderly people. Vanda roxburghii Rbr. root has been used traditionally in Bangladesh as tonic to brain and in the treatment of nervous system disorders including AD. Therefore, we aimed to investigate the cholinesterase inhibitory activities and antioxidant properties of the extracts...
