dorema aucheri boiss. (apiaceae) is an endemic plant growing in iran. this plant is used as food and its extracts are recommended for the treatment of a wide range of diseases. to conduct this study, leaf, stem, and flower of d. aucheri were collected from near yasouje, iran. antioxidant and antimicrobialeffects of methanol extracts were measured. further, total phenolic,flavonoid, anthocyanin,...

Leaf and oleoresin fractions of both alcoholic and petroleum ether extracts of Araucaria bidwillii exhibited significant prolongation of pentobarbitones sleeping time at a dose of 300 and 100 mg/kg body weight respectively in mice. This effect is more pronounced for oleoresin than the leaf extracts. Further, the two extracts seem to possess analgesic effect comparable to aspirin by writing meth...

Ultraviolet (UV) irradiation causes damage in skin by generating excessive reactive oxygen species (ROS) and induction of matrix metalloproteinases (MMPs), leading to skin photoageing. Dandelion extracts have long been used for traditional Chinese medicine and native American medicine to treat cancers, hepatitis, and digestive diseases; however, less is known on the effects of dandelion extract...

In this study, we aimed to compare supercritical carbon dioxide extraction and ethanol extraction for isoegomaketone (IK) content in perilla leaf extracts and to identify the optimal method. We measured the IK concentration using HPLC and inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells from the extracts. The IK concentration was 10-fold higher in perilla leaf extra...

The effect of alcoholic extracts of leaf from Araucaria bidwillii Hook. [ABH] (Family: Araucariaceae) was evaluated in experimental models of pain and inflammation. Oral administration of 100, 200 and 300 mg/kg of leaf extracts of ABH were used for the above study. The leaf extract at 300 and 200 mg/kg showed significant reduction in acetic acid induced writhings in mice with a maximum effect o...

The chemical composition, antioxidant potential and antimicrobial activity were studied in six walnuts (Juglans regia L.) cultivars (cv. Franquette, Lara, Marbot, Mayette, Mellanaise and Parisienne) produced in Portugal. Concerning their chemical composition the main constituent of fruits was fat ranging from 78.83% to 82.14%, being the nutritional value around 720kcal per 100g of fruits. Linol...

The antioxidant activity of several Malaysian plant extracts was analyzed simultaneously with their pro-oxidant capacity. This ratio represents an index (ProAntidex) of the net free radical scavenging ability of whole plant extracts. We observed that ethanolic extracts of Nephelium lappaceum peel, Fragaria x ananassa leaf, Lawsonia inermis leaf, Syzygium aqueum leaf and grape seed had a lower P...

The polyphenolic constituents and antioxidant activity of aqueous and acetone extracts of Vachellia karroo leaves were determined in order to evaluate its efficacy in scavenging radicals such as DPPH, ferric reducing power and nitric oxide as an antioxidant model. The flavonols and flavonoid and phenolic content of the leaf extracts were also accessed using benchmark phytochemical reaction meth...

BACKGROUND Rhododendron leaf extracts were previously found to exert antimicrobial activities against a range of Gram-positive bacteria. In this study, we investigated which of the extracts with these antimicrobial properties would be best suited for further exploitation. Specifically, the project aims to identify biologically active compounds that affect bacterial but not mammalian cells when ...
