Annona sp: Plants with multiple applications as alternative medicine - a review

Annona species have been used as a natural remedy for a variety of illnesses with antiparasitic, antispasmodic, antidiarrheal, antiulcer, sedative, analgesic, hypotensive, and vermifugal effects. These properties are due to the presence of a number of bioactive compounds on the leaves, fruit, seeds, and stem. The aim of this review is to show the main species of Annona, their medicinal properties and the chemical constituents that may be related to these effects. In the leaves it is possible to find acetogenins, annopentocins A, B, and C, cis- and trans-annomuricin-D-ones, goniothalamicin, arianacin, and javoricin, related to anticancer properties. Quercetin-3-O-glucoside, also found in the leaves mediates antidiabetic and antioxidative effects. In the fruit are found annonaine, nornuciferine and asimilobine, associated to antidepressive effects. In the seeds are found muricatetrocin A and muricatetrocin B, longifolicin, corossolin, corossolone, uvarigrandin A, bullatacin, squamotatin. These acetogenins are associated with anticancer effects. Cyclosquamosin B, quercetin, and cyclosquamosin from the seeds have respectively vasorelaxant, antithyroidal and, antiinflammatory activity. In the stem parts there are several components as N-trans-feruloyltyramine, N-p-coumaroyltyramine, and N-trans-caffeoyltyramine, lignans, syringaresinol, syringaldehyde, beta-sitosterol and beta-sitosterol-beta-D-glucoside which exhibit antiplatelet aggregation activity. Copaene, patchoulane, 1H-cycloprop (e) azulene and kaur-16-en-19-oic acid found in the barks exhibit significant central as well as peripheral analgesic and antiinflammatory activities. The properties of the biological compounds in Annona species support information that may provide validation for its medicinal uses, but further studies should be performed to establish ideal and safe doses of consumption to ensure the effectiveness of the benefits. © 2012 Bentham Science Publishers.

Essential oils from medicinal and aromatic plants: A review of the gastroprotective and ulcer-healing activities

Gastric ulcer is an excoriated area of the gastric mucosa. It is among the predominant gastrointestinal chronic diseases. The essential oils represent an important part of the traditional pharmacopoeia in many countries and have been successfully used for gastroprotection and ulcer healing. Thus, this review presents the experimental activity of essential oils traditionally used in the gastric ulcer prevention and treatment, considering their families, part of the plant studied, bioassays, and their mechanisms of gastroprotection and ulcer healing, with the aim of stimulating novel studies in the search for a new phytomedicine to treat gastric diseases. © 2012 The Authors Fundamental and Clinical Pharmacology © 2012 Société Française de Pharmacologie et de Thérapeutique.

Casearia sylvestris Swartz Extract Release Using Natural Rubber Latex Biomembranes as Carrier

The Natural Rubber Latex (NRL) from Hevea brasiliensis has shown promise in biomedical applications due to its low cost, easy handling, mechanical properties and biocompatibility, being used for bone regeneration and wound healing due to its natural stimulus to angiogenesis. The aim of this work was to incorporate Casearia sylvestris Sw. extract in NRL biomembranes and study its release behavior. The complex membrane-extract has as object of study a new approach of using C. sylvestris extract in the treatment of wounds, for possessing antiseptic activity, anti-inflammatory and analgesic properties. The C. sylvestris species (Salicaceae), popularly known as "guaçatonga", presents great distribution and is used in folk medicine as antiulcer, wound healing, anti-snake venom, properties which have been proven and related to clerodane diterpenes (casearins A-X). The release rate of C. sylvestris compounds from extract-membrane complex was monitored and analyzed using the method of optical spectroscopy (UV-VIS). The release varied with temperature ranging from 14 to 33 days, releasing more than 90%, with an interesting and promising biomedical application, such as wound healing and burns.
