Le piante utilizzate nella medicina popolare dell'Ogliastra (Sardegna Centro-Orientale) per la cura delle patologie del sistema muscolo-scheletrico

Abstract: Spontaneous plants used in Sardinian folk medicine for the treatment of musculoskeletal system diseases. In this work the authors propose de results of an ethnobotanical survey developed in some villages of central-eastern Sardinia. The 482 interviews allowed to enumerate 52 plants, attributed to 49 genera and 36 families, utilized in folk medicine for the treatment of musculoskeletal system diseases.

Plants and traditional knowledge: An ethnobotanical investigation on Monte Ortobene (Nuoro, Sardinia)

Abstract: Most of the traditional knowledge about plants and their uses is fast disappearing as a consequence of socio-economic and land use changes. This trend is also occurring in areas that are historically exposed to very few external influences, such as Sardinia (Italy). From 2004 to 2005, an ethnobotanical investigation was carried out in the area of Monte Ortobene, a mountain located near Nuoro, in central Sardinia. Data were collected by means of semi-structured interviews. All the records – defined as 'citations', i.e. a single use reported for a single botanical species by a single informant – were filed in a data base ('analytical table'), together with additional information: i.e. local names of plants, parts used, local frequencies, and habitats of plants, etc. In processing the data, plants and uses were grouped into general ('categories') and detailed ('secondary categories') typologies of use. Some synthetic indexes have also been used, such as Relative Frequency of Citation (RFC), Cultural Importance Index (CI), the Shannon-Wiener Index (H'), and Evenness Index (J). Seventy-two plants were cited by the informants as being traditionally used in the area. These 72 'ethnospecies' correspond to 99 botanical taxa (species or subspecies) belonging to 34 families. Three-hundred and one citations, 50 secondary categories of use, and 191 different uses were recorded, most of them concerning alimentary and medicinal plants. For the alimentary plants, 126 citations, 44 species, and 13 different uses were recorded, while for the medicinal plants, there were 106 citations, 40 species, and 12 uses. Few plants and uses were recorded for the remaining categories. Plants and uses for each category of use are discussed. Analyses of results include the relative abundance of botanical families, wild vs. cultivated species, habitats, frequency, parts of plant used, types of use, knowledge distribution, and the different cultural importance of the species in question. The study provides examples of several interesting uses of plants in the community, which would seem to show that the custom of using wild plants is still alive in the Monte Ortobene area. However, many practices are no longer in use, and survive only as memories from the past in the minds of elderly people, and often only in one or just a few informants. This rapidly vanishing cultural diversity needs to be studied and documented before it disappears definitively.

Plant-derived natural medicines for the management of depression: an overview of mechanisms of action.

Abstract: Depression is a serious widespread psychiatric disorder that affects approximately 17% of people all over the world. Exploring the neurological mechanisms of the antidepressant activity of plant-derived agents could have a crucial role in developing natural drugs for the management of depression. The aim of the present study is to review the neurological mechanisms of action of antidepressant plants and their constituents. For this purpose, electronic databases, including PubMed, Science Direct, Scopus, and Cochrane Library, were searched from 1966 to October 2013. The results showed that several molecular mechanisms could be proposed for the antidepressant activity of medicinal plants and their constituents. Hypericum species could normalize brain serotonin level. Liquiritin and isoliquiritin from Glycyrrhiza uralensis rhizome act via the noradrenergic system. Rosmarinus officinalis and curcumin from Curcuma longa interact with D1 and D2 receptors as well as elevate the brain dopamine level. Sida tiagii and Aloysia gratissima involve γ-aminobutyric acid and N-methyl-D-aspartate receptors, respectively. Fuzi polysaccharide-1 from Aconitum carmichaeli could affect brain-derived neurotrophic factor signaling pathways. Psoralidin from Psoralea corylifolia seed modulate the hypothalamic-pituitary-adrenal axis. The total glycosides of Paeonia lactiflora demonstrate an inhibitory effect on both subtypes of monoamine oxidase. 3,6'-Di-o-sinapoyl-sucrose and tenuifoliside A from Polygala tenuifolia exhibit cytoprotective effects on neuronal cells. Further preclinical and clinical trials evaluating their safety, bioefficacy, and bioavailability are suggested to prove the valuable role of natural drugs in the management of depressive disorders.

Fruit pod extracts as a source of nutraceuticals and pharmaceuticals.

Abstract: Fruit pods contain various beneficial compounds that have biological activities and can be used as a source of pharmaceutical and nutraceutical products. Although pods or pericarps are usually discarded when consuming the edible parts of fruits, they contain some compounds that exhibit biological activities after extraction. Most fruit pods included in this review contain polyphenolic components that can promote antioxidant effects on human health. Additionally, anti-inflammatory, antibacterial, antifungal and chemopreventive effects are associated with these fruit pod extracts. Besides polyphenolics, other compounds such as xanthones, carotenoids and saponins also exhibit health effects and can be potential sources of nutraceutical and pharmaceutical components. In this review, information on fruit pods or pericarp of Garcinia mangostana, Ceratonia siliqua, Moringa oleifera, Acacia nilotica, Sapindus rarak and Prosopis cineraria is presented and discussed with regard to their biological activity of the major compounds existing in them. The fruit pods of other ethno- botanical plants have also been reviewed. It can be concluded that although fruit pods are considered as being of no practical use and are often being thrown away, they nevertheless contain compounds that might be useful sources of nutraceutical and other pharmaceutical components.
