A phytochemical study of two plant species, Viscum cruciatum Sieber and Crataegus monogyna Jacq., was completed to investigate the influence of the parasite Viscum cruciatum on the host Crataegus monogyna. The study was carried out with two samples and consisted of hexane extracts of the Viscum cruciatum parasitizing on Crataegus monogyna and C monogyna. In these samples ursolic acid, beta-sito...
The lipophilic composition of wild Arbutus unedo L. berries, collected from six locations in Penacova (center of Portugal), as well as some general chemical parameters, namely total soluble solids, pH, titratable acidity, total phenolic content and antioxidant activity was studied in detail to better understand its potential as a source of bioactive compounds. The chemical composition of the li...
BACKGROUND The aim of this work was to evaluate the immunomodulatory effect of the methanol extract (MeOH) from Chrysophyllum cainito leaves on the MΦs functions. MATERIAL AND METHODS Peritoneal murine MΦs isolated from Balb/c mice were treated with the MeOH extract and stimulated with LPS. The effect on the phagocytosis was evaluated by flow cytometry assay. The nitric oxide (NO) and hydroge...
The aerial parts of Salvia glutinosa afforded in addition to lupeol, a - and ? - amyrin a furanosesquiterpene, its structure being established by high field NMR techniques. The relative configuration at C-1, C-10, C-4, C-5 and C-6 of 6?tigloyloxyglechomafuran 1 was determined by the observed NOE'S
Frankincense is an aromatic terpenoid oleo-gum resin produced by trees in the genus Boswellia. It has been used for medicinal and religious purposes millennia, today important component perfume aromatherapy. The of Boswellia frereana especially prized, found to contain a high proportion monoterpenes. However, previous studies have relied on commercial samples; this study, we characterize compos...
