The chemical composition of the essential oils of Salvia desoleana Atzei & Picci and Salvia sclarea L. from Sardinia (Italy) was analysed by GC and GC/MS. S. desoleana oil had a high content of monoterpenic esters (linalyl acetate and alpha-terpinyl acetate) and a lower amount of the corresponding alcohols while S. sclarea oil was characterised by a higher(More)
Lyophilized aqueous extracts obtained from Agave americana L (Agavaceae) collected in the north of Sardinia were characterized with regard to their steroidal sapogenin content. Extracts of A. americana and genins isolated from them were evaluated for anti-inflammatory properties by testing their effects on carrageenin-induced edema. The effect of orally(More)
This study investigated the effects of some essential oils onLimantria dispar (Lepidoptera: Lymantridae, gypsy moth) larvae, one of the most serious pests of cork oak forests. The essential oils were first formulated as oil in water (o/w) emulsions and used in laboratory bioassays to assess their lethal concentration (LC50). Microcapsules containing the(More)
Linalool and linalyl acetate are the principal components of many essential oils known to possess several biological activities, attributable to these monoterpene compounds. In this work, we evaluated individually the anti-inflammatory properties of (-) linalool, that is, the natural occurring enantiomer, and its racemate form, present in various amounts in(More)
In this study, microspheres were prepared by a spray-drying technique using solutions of ketoprofen and two polymers, cellulose acetate butyrate (CAB) and hydroypropylmethylcellulose phthalate (HPMCP), in different weight ratios. Different total concentrations were used in the feed solutions: 3, 6 and 9% w/v. The spray-dried microparticles were(More)
Linalool is a monoterpene compound commonly found as a major component of the essential oils of several aromatic plant species, many of which are used in traditional medical systems as analgesic and anti-inflammatory remedies. We previously reported that (-)-linalool, the natural occurring enantiomer, plays a major role in the anti-inflammatory activity(More)
This research investigated the use of sodium alginate for the preparation of hydrophylic matrix tablets intended for prolonged drug release using ketoprofen as a model drug. The matrix tablets were prepared by direct compression using sodium alginate, calcium gluconate, and hydroxypropylmethylcellulose (HPMC) in different combinations and ratios. In vitro(More)
In this study the effect of vehicle on in vitro diffusion of diclofenac sodium (DS) from new different formulations such as Carbopol gel (A), Sodium lauryl sulphate cream (B) and Carbopol cream (C) was evaluated with Franz diffusion cells using hydrophilic and hydrophobic synthetic membranes. The commercial formulation Voltaren Emulgel was used as(More)
In the light of recent studies, which have shown that the essential oil derived from some Lamiaceae species has appreciable anti-inflammatory activity, moderate anti-microbial action and the ability to inhibit induced hyperalgesia, an assessment of the diffusion and permeation of Salvia desoleana Atzei & Picci (S. desoleana) essential oil through porcine(More)
Ketoprofen (KP) is a potent nonsteroidal anti-inflammatory drug (NSAID) widely used in clinical practice for the control of acute and chronic pain of soft tissues and skeletal muscle system. The importance of KP in the therapeutic field, has stimulated the development of topical dosage forms to improve its percutaneous absorption through the application(More)
