Abstract

Abstract: The topical anti-inflammatory, free radical scavenging and antifungal activities of essential oils and extracts of Commiphora erythraea (Ehrenb.) Engl. resin were investigated. The hexane extract significantly inhibited oedema when applied topically in Croton oil-induced ear oedema assay in mice. The same extract showed antioxidant activity in DPPH radical scavenging assay. A bioguided separation of the hexane extract led to the isolation of furanosesquiterpenoids 1 and 2 that showed a weak antifungal activity, while compounds 3–5 resulted to be antioxidant (EC50 4.28, 2.56 and 1.08mg/mL, respectively) and anti-inflammatory (30, 26 and 32% oedema reduction, respectively).

2. Antioxidant activity of Citrus paradisi seeds glyceric extract

Subjects
*MEDICINAL plants, *XANTHINE, *CITRUS products, *CHEMILUMINESCENCE
Abstract

The antioxidant activity of Citrus paradisi (grapefruit) seeds glyceric extract dissolved in ethanol and in aqueous media was evaluated using three different methods: evaluation by DPPH assay, by 5-lipoxygenase assay and by luminol/xanthine/xanthine oxidase chemiluminescence assay. The total phenolic content was determined by the Prussian Blue method opportunely modified. The grapefruit seeds glyceric extract utilized as aqueous solutions demonstrated antioxidant properties better than those displayed by alcoholic solutions. [Copyright &y& Elsevier]

3. Essential oil composition and antioxidant activity of aerial parts of Grindelia robusta from Central Italy

Author

Fraternale, Daniele, Giamperi, Laura, Bucchini, Anahi, and Ricci, Donata

Subjects
*ESSENTIAL oils, *PLANT extracts, *GRINDELIA
Abstract

Abstract: The chemical composition of the essential oil obtained from Grindelia robusta aerial parts from central Italy was analyzed by GC and GC/MS and 45 components were identified. Borneol (15.2%), α pinene (10.3%), trans-pinocarveol (7.0%), bornyl acetate (4.5%), limonene (4.3%) were the main components. The antioxidant activity of the essential oil was evaluated using the DPPH and 5-lipoxygenase tests. [Copyright &y& Elsevier]
