UNLABELLED BACKGROUND Extensive research has been performed worldwide and important evidences were collected to show the immense potential of plants used in various traditional therapeutic systems. The aim of this work is to investigate the different extracting solvents in terms of the influence of their polarity on the extracting ability of bioactive molecules (phenolic compounds) from the ...

Procedure of manufacturing K. pinnata water extracts containing cecropin P1 (CecP1) from the formerly described transgenic plants is established. It included incubation of leaves at +4°C for 7 days, mechanical homogenization of leaves using water as extraction solvent, and heating at +70°C for inactivating plant enzymes. Yield of CecP1 (after heating and sterilizing filtration) was 0.3% of tota...

We evaluated the antioxidant activity and tyrosinase inhibitory effects of Pleurotus ostreatus fruiting bodies extracted with acetone, methanol, and hot water. The antioxidant activities were tested against β-carotene-linoleic acid, reducing power, 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity, and ferrous chelating ability. Furthermore, phenolic acid and flavonoid contents wer...

Also it contains antioxidant components and has shown beneficial effects in neurological diseases. In this study we investigated the effects of Ginkgo leaf extract on spatial memory impairment and hippocampal neuronal loss caused by dia...

The antioxidant effect of aqueous extract of the bark of FB has been evaluated in hypercholesterolaemic rabbits. The water extracts of the bark of Ficus benghalensis at a dose of 50 mg/kg body weight per day in addition to cholesterol suspended in oil. There results show that the water extract of the bark of Ficus benghalensis has significant antioxidant effect, in addition to hypolipidaemic ef...

introduction: alhagi camelorum belongs to the leguminosae family is used in iranian folk medicine to treat some gastric diseases. the present study was undertaken to evaluate the alhagi camelorum aqueous extract for anti-ulcer activity in rats. methods: male wistar rats were pretreated with the a. camelorum aqueous extract (150, 300 or 450 mg/kg of b.w., p.o.) before induction of gastric ulcer ...

The effect of hot water extract of fruits of Helicteres isora on glucose uptake was studied in rodent skeletal muscle cells (L-6 cells) involved in glucose utilization. H. isora is an antidiabetic medicinal plant being used in Indian traditional medicine. Hot water extracts were analysed for glucose uptake activity and found to be significantly active at 200 mug/ml dose comparable with insulin ...
