Antioxidant, Anti-diabetic, Anti-cholinesterase, and Nitric Oxide Inhibitory Activities of Fruiting Bodies of Agaricus brasiliensis

Cholinesterase Inhibitory, Anti-oxidant and Anti-tyrosinase Activities of Three Iranian Species of Dracocephalum

Background and objectives: Dracocephalum species are mentioned in Iranian traditional medicine for enhancement of cognitive performance. In the present study, the acetyl cholinesterase inhibitory and butyryl cholinesterase inhibitory activities as well as the anti-oxidant and anti-tyrosinase effects of three Iranian Dracocephalum species (D. kotschyi,...

Assessment of antioxidant, anti-inflammatory, anti-cholinesterase and cytotoxic activities of Henna (Lawsonia inermis) flowers

Lawsonia inermis flowers were evaluated for chemical and biological properties for the first time. Extracts were prepared successively by hexane, chloroform and methanol. Phenolics (7.8-239.0g gallic acid equivalent/kg of dry mass), tannins (12.5148.5mg cathechin equivalent/kg of dry mass) and flavonoids (36.2-43.75mg quercetin equivalent/kg of dry mass) were quantified. Methanol extract has a ...

Isolation and Characterisation of Anti-diabetic Pharmacological Activities of Phytoestrogens

Antiherpetic mechanism of a sulfated derivative of Agaricus brasiliensis fruiting bodies polysaccharide.

OBJECTIVE To study the anti-herpes simplex virus (HSV) activity of a (1→6)-(1→3)-β-D-glucan isolated from Agaricus brasiliensis fruiting bodies (FR) as well as its chemically sulfated derivative (FR-S). METHODS The antiherpetic activity and mechanism of action was studied by viral plaque assay applying different methodological strategies. RESULTS Although FR presented no in vitro antiherpet...

Antioxidant Activities and Tyrosinase Inhibitory Effects of Different Extracts from Pleurotus ostreatus Fruiting Bodies

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...
