The wound healing is a complex process which, sometimes, can be a problem in public health because of the possibility of physical disability or even death. Due to the lack of a gold standard drug in skin wound treatment and aiming at the discovery of new treatments in skin repair and the mechanisms involved in the process, we used oleoresin (OR) from Copaifera langsdorffii and hydroalcoholic ex...

Federal agencies of several nations have or are currently developing guidelines for critical forest soil acid loads. These guidelines are used to establish regulations designed to maintain atmospheric acid inputs below levels shown to damage forests and streams. Traditionally, when the critical soil acid load exceeds the amount of acid that the ecosystem can absorb, it is believed to potentiall...

Lipid oxidation, color, and volatiles of double-packaged pork loins with various oleoresin or oleoresin-tocopherol combinations were determined to establish the best oleoresin-tocopherol conditions that can improve the quality of irradiated raw and cooked pork loins. Rosemary and α-tocopherol combination at 0.05% and 0.02% of meat weight, respectively, showed the most potent antioxidant effects...

In an analysis of Australian grown P. radiata marked changes were found in the relative proportions and compositions of the resin acids. fattY acids, and fatty acid esters associated with heartwood formation. While the proportion of resin acids increased substantially in the heartwood, there was little change in resin acid composition from outer sapwood to inner heartwood. Extracts from wood of...

On the basis of authentic references from the literature of ayurveda and on our own observations, Puskara-Guggulu, a combination of oleoresin of C. mukul and I-recemosa, has been clinically tried on a series of ECG proved 50 patients of ischaemic heart disease. This has been administered in the dose of 6 gms per day, in three divided doses upto a period of four months. Precordial pain, discomfo...

Background Breu is an aromatic oleoresin which has been used by Amazonian traditional communities as a remedy for headaches and migraines by burning and inhaling the smoke produced during its combustion. This study evaluated the antinociceptive and sedative activities of formulations containing breu essential oils administered by inhalation. Methods Five different formulations (A-E) containin...

The Anacardiaceae is an important and worldwide distributed family of ecological and socio-economic relevance. Notwithstanding that, molecular studies in this family are scarce and problematic because of the particularly high concentration of secondary metabolites-i.e. tannins and oleoresins-that are present in almost all tissues of the many members of the group, which complicate the purificati...

Discrepant and incomplete interpretations of fruits of Pterodon have been published, especially on the structural interpretation of the pericarp portion that remain attached to the seed upon dispersal. The present work clarified these doubts and analyzed ultrastructural aspects of the Pterodon emarginatus diaspores using light and transmission electron microscopes. Cell divisions are prevalent ...

Southern pine beetles and associated pathogenic fungi represent the largest biotic threat to pine forests in the southeastern USA. The two primary defensive mechanisms of the tree to the beetle-fungal complex are the primary oleoresin flow and the concentrations of preformed and induced secondary compounds. We compared oleoresin flow and concentrations of phloem nutrients, soluble sugars, starc...

Lactic acid bacteria (LAB) can reduce Escherichia coli O157:H7 and Salmonella spp. in ground beef during storage. Furthermore, the addition of rosemary oleoresin (RO), a natural antioxidant, to ground beef has been shown to increase shelf life and is commonly used in modified-atmosphere packaged (MAP) ground beef. This study evaluated the effects of LAB and RO treatment on the shelf life and st...
