Traditional Salads and Soups with Wild Plants as a Source of Antioxidants: A Comparative Chemical Analysis of Five Species Growing in Central Italy.

The interest and demand for nutraceuticals are rapidly increasing in many industrialized countries due to the emergence of health risks associated with the increased consumption of processed foods. Several wild Mediterranean plants used as traditional foods are an extraordinary source of nutraceutical substances with antioxidant properties. This study has two main aims: (1) to quantify the antioxidant properties of traditional wild food plants and (2) to determine if their use in soups (i.e., the cooking process) can alter their beneficial properties. We have evaluated the antioxidant capacity (ABTS, DPPH) and the Total Phenolic Content (Folin-Ciocalteu) of five herbaceous plants traditionally consumed in several areas of Central Italy: (A) Reichardia picroides (L.) Roth, (B) Hypochaeris radicata L., (C) Cichorium intybus L., (D) Tordylium apulum L., and (E) Helminthotheca echioides (L.) Holub. Our analyses show good levels of antioxidant capacity for all plants, with Reichardia picroides and Helminthotheca echioides having the highest levels. There is a high correlation between the antioxidant activity and the Total Phenolic Content especially in Reichardia picroides (R2=0.92) and Hypochaeris radicata (R2=0.93). Boiling the species caused a general decrease in the antioxidant activity and polyphenols. Our study confirms the health benefits of consuming wild plants, especially raw ones in salads. It also supports the use of ethnobotanical information to study and then promote the consumption of wild food plants.

Ethnobotanical study of Loloh: Traditional herbal drinks from Bali (Indonesia).

ETHNOPHARMACOLOGICAL RELEVANCE: Loloh are herbal drinks produced and consumed exclusively in Bali (Indonesia) to prevent and treat different ailments. This is the first study to document plants species used as Loloh, reporting the phytochemical components and pharmacological properties of the most cited plants. Documenting the plants used in herbal drinks in Bali by local communities to treat various ailments (providing some information on phytochemistry and pharmacology of the most interesting plants). MATERIALS AND METHODS: Ethnobotanical data were obtained through semi-structured interviews (individual and group discussions) and questionnaires. Plant specimens were collected, identified and made into herbarium vouchers. RESULTS: A total of 51 plants species (belonging to 32 families) have been documented for their use in the various preparation of Loloh. Different plants and plant parts are used to prepare Loloh to treat heartburn, fever, diarrhea, hypertension, aphthous stomatitis (canker sores), and other minor health problems. These plants are mainly prepared as decoctions, are juiced or simply added to the preparation. The most cited plants (>30 informants) are Alstonia scholaris (L.) R. Br., Blumea balsamifera (L.) DC., Cinnamomum burmanni Nees ex Bl., and Piper betle L. These plants are well studied with multiple demonstrated pharmacological activities (e.g., antimicrobial, anticancer, antidiabetic). CONCLUSION: The Balinese communities still preserve a rich ethnobotanical knowledge. Several species are well known for their pharmacological properties, but some [such as Pneumatopteris callosa (Blume) Nakai and Dendrocnide stimulans (L. f.) Chew] are understudied and could be promising candidates for further research.

Ethnobotanical investigation on wild medicinal plants in the Monti Sicani Regional Park (Sicily, Italy).

ETHNOPHARMACOLOGICAL RELEVANCE: The area of the "Monte Sicani Regional Park" (Central Western Sicily, southern Italy) has been quantitatively and extensively investigated in an ethnobotanical study for the first time. A total of 108 wild species are used for medicinal purposes, while, according to our study, the uses of 9 species have not previously been reported in ethnobotanical studies in Italy (e.g., the use of Kickxia elatine (L.) Dumort. for the treatment of hyperhydrosis of the feet, the use of Lavatera agrigentina Tineo for cough and bronchitis). AIM OF THE STUDY: The aim of this paper is to analyze, through quantitative indicators, the extent of the current knowledge on medicinal uses of plants in the area, evaluating also the features of uniqueness and commonality of this knowledge in comparison with other Italian and Mediterranean areas. METHODOLOGY: Semi-structured interviews were carried out in the local communities between 2009 and 2010 within the Monti Sicani Regional Park with local people retained experts in rural traditions. A total of 230 people were interviewed about their knowledge on medicinal plant uses. Local plant uses were evaluated using ethnobotanical indices (e.g., cultural importance index, ethnobotanicity index, informant consensus factor) and then compared with uses in other localities in Sicily, Italy and the Mediterranean basin. RESULTS: Local communities currently use a total number of 108 wild species (43 families) as remedies for human and livestock ailments. The majority of plants are used in the treatment of articular, skin and gastrointestinal problems. The use of some species is limited to Sicily (e.g., Rhus coriaria L., Athamanta sicula L., Senecio delphinifolius Vahl). CONCLUSIONS: The research shows an ongoing process of cultural erosion in an advanced stage, but results still highlight an interesting cultural identity as regards the local folk medicine.

Plants used in artisanal fisheries on the Western Mediterranean coasts of Italy.

BACKGROUND: Artisanal fisheries in the Mediterranean, especially in Italy, have been poorly investigated. There is a long history of fishing in this region, and it remains an important economic activity in many localities. Our research entails both a comprehensive review of the relevant literature and 58 field interviews with practitioners on plants used in fishing activities along the Western Mediterranean Italian coastal regions. The aims were to record traditional knowledge on plants used in fishery in these regions and to define selection criteria for plant species used in artisanal fisheries, considering ecology and intrinsic properties of plants, and to discuss the pattern of diffusion of shared uses in these areas. METHODS: Information was gathered both from a general review of ethnobotanical literature and from original data. A total of 58 semi-structured interviews were carried out in Liguria, Latium, Campania and Sicily (Italy). Information on plant uses related to fisheries were collected and analyzed through a chi-square residual analysis and the correspondence analysis in relation to habitat, life form and chorology. RESULTS: A total of 60 plants were discussed as being utilized in the fisheries of the Western Italian Mediterranean coastal regions, with 141 different uses mentioned. Of these 141 different uses, 32 are shared among different localities. A multivariate statistical analysis was performed on the entire dataset, resulting in details about specific selection criteria for the different usage categories (plants have different uses that can be classified into 11 main categories). In some uses, species are selected for their features (e.g., woody), or habitat (e.g., riverine), etc. The majority of uses were found to be obsolete (42%) and interviews show that traditional fishery knowledge is in decline. There are several reasons for this, such as climatic change, costs, reduction of fish stocks, etc. CONCLUSIONS: Our research correlates functional characteristics of the plants used in artisanal fishery and habitats, and discusses the distribution of these uses. This research is the first comprehensive outline of plant role in artisanal fisheries and traditional fishery knowledge in the Mediterranean, specifically in Italy.

Folk phytotherapy of the Amalfi Coast (Campania, Southern Italy).

ETHNOPHARMACOLOGICAL RELEVANCE: In the Amalfi Coast, Campania (Southern Italy) a total number of 102 plant species are used for medicinal purposes, with a total of 276 different uses, among which, 183 are new for the area and 34 are new for Italy. MATERIALS AND METHODS: Data were obtained through semi-structured interviews with 214 inhabitants of the study area. RESULTS: Folk phytotherapy is intended mainly as a mode of primary health care in order to heal minor illnesses, and especially disease related to the respiratory, urogenital, skeletal and gastrointestinal systems and skin problems. Among the new uses, interesting are those of Lobularia maritima (L.) Desv. subsp. maritima against abdominal pains and in case of cold and coughs; of Calystegia sylvatica (Kit. in Schrad) Griseb as resolvent for pimples and of Santolina neapolitana Jourdan & Fourr., against cough. The knowledge of medicinal plants is mainly retained by middle aged housewives, even though, it is declining. Many remedies are shared in other Italian regions or Mediterranean countries, while some uses seem to be specific to the area. CONCLUSIONS: In the study area, the ethnobotanical medicinal knowledge seems to have many elements in common with other areas, but also many unique features. This rich tradition competes with modern ways of life: plants still play an important role in the health care practices, even if the related knowledge is disappearing.

Ethnobotany as a pharmacological research tool and recent developments in CNS-active natural products from ethnobotanical sources.

The science of ethnobotany is reviewed in light of its multi-disciplinary contributions to natural product research for the development of pharmaceuticals and pharmacological tools. Some of the issues reviewed involve ethical and cultural perspectives of healthcare and medicinal plants. While these are not usually part of the discussion of pharmacology, cultural concerns potentially provide both challenges and insight for field and laboratory researchers. Plant evolutionary issues are also considered as they relate to development of plant chemistry and accessing this through ethnobotanical methods. The discussion includes presentation of a range of CNS-active medicinal plants that have been recently examined in the field, laboratory and/or clinic. Each of these plants is used to illustrate one or more aspects about the valuable roles of ethnobotany in pharmacological research. We conclude with consideration of mutually beneficial future collaborations between field ethnobotanists and pharmacologists.
