Seaweeds are known to be a good supply of key nutrients including carbohydrates, protein, minerals, polyunsaturated lipids, as well as several other health-promoting compounds capable of acting on a wide spectrum of disorders and/or diseases. While these marine macroalgae are deeply rooted in the East Asian culture and dietary habits, their major application in Western countries has been in the phycocolloid industry. This scenario has however been gradually changing, since seaweed consumption is becoming more common worldwide. Among the numerous edible seaweeds, members of the genus Fucus have a high nutritional value and are considered good sources of dietary fibers and minerals, especially iodine. Additionally, their wealth of bioactive compounds such as fucoidan, phlorotannins, fucoxanthin and others make them strong candidates for multiple therapeutic applications (e.g., antioxidant, anti-inflammatory, anti-tumor, anti-obesity, anti-coagulant, anti-diabetes and others). This review presents an overview of the nutritional and phytochemical composition of Fucus spp., and their claimed biological activities, as well as the beneficial effects associated to their consumption. Furthermore, the use of Fucus seaweeds and/or their components as functional ingredients for formulation of novel and enhanced foods is also discussed.

Quinoa (Chenopodium Quinoa Willd.) is a psudocereal plant which has been consumedfor 5000 years. It has attracted the attention all over the world because ofits adaptability to all climate conditions and its biological, nutritional importance.The year of 2013 was declared international quinoa year due to the fact that it is anold plant that contributes to world food security. Quinoa has rich nutritional valuefrom protein, essential aminoacid, minerals and vitamins. Also it contains saponins,phytosterols, phytoecdysteroids, phenolics that provides its biological activities. Thesecomponents may positively affect on health such as metobolic, gastrointestinal andcardiac influences but nowadays there are limited studies on human health. In thisreview, the cardiovascular effects of quinoa will be mentioned.Key words: antioxidant–biological activities–cardiovascular effects–quinoa–nutritional value

ABSTRACTSolanum nigrum is a paramount in medicinal perspective and belongs to family Solanacea. From different parts of the plant significant pharmacological and biological activities have been reported previously.  In the present study, the ethanolic extract of leaves was investigated for phytochemical analysis, vitamin and mineral content. Phytochemical analysis of the leaves revealed the presence of phenols, alkaloids, flavonoids, glycosides, saponins, tannins, phytosterols and triterpenoides. The leaves extract was found to contain appreciable amounts of flavonoids and phenols. The extract showed the presence of vitamins such as ascorbic acid, folic acid, and niacinamide. It has been found that the leaves of Solanum nigrum is rich in minerals like copper, magnesium, manganese, vanadium, chromium, calcium, zinc, sodium, and potassium. The antioxidant (free radical scavenging) activity of the extract was determined against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) ABTS, Nitric oxide(NO) and Superoxide Scavenging assays. Solanum nigrum leaves extract was found to be antioxidant in nature which is evident from DPPH, ABTS, NO, Superoxide radical scavenging assays. These findings suggest that Solanum nigrum possess biologically important phytoconstituents, significant amounts of vitamins and minerals. IN addition, S. nigrum leaves extract exert free radical scavenging potential in vitro.Key words: Medicinal plants; Solanum nigrum leaves; phytoconstiuents;Antioxidant.

The aerial parts of Onopordum illyricum L. (Asteraceae) are eaten raw in salad in the Mediterranean area, representing a food of good nutritional value. Extracts of different parts of this plant have been analyzed by HPLC/DAD/ESIMS and the major compounds identified by NMR spectroscopy. Fatty acids, sesquiterpene lactones, triterpenes and polyphenols (flavones and caffeoyl quinic acids) fully describe the plant metabolism during the vegetation year. All the metabolites are non toxic nutrients, and are reported in the literature to possess biological activities positive for health, confirming the beneficial use in the diet of this thistle

English For more than 30 years, field studies have shown that chimpanzees ingest items of low nutritional value such as rough leaves, bitter stems and clay, apparently thereby protecting themselves against parasites and modulating their health. The authors describe the diversity and the biological activities of items of low nutritional value used by Kanyawara chimpanzees in Uganda, according to scientific observations enriched by the viewpoints of local field assistants and a traditional healer. Their perception of chimpanzees' behaviour and the overlap with human medicinal uses led the authors to explore chimpanzee behaviour in a comparative cultural perspective. In spite of the rarity of such observations on wild individuals, study of self-medicative practices offers the opportunity to suggest an epistemology of the chimpanzee so as to better understand the acquisition and transmission of behaviours linked to diseases. French Depuis une trentaine d'années, des études de terrain ont montré que les chimpanzés ingèrent régulièrement des matériels de faible valeur nutritive comme des feuilles rugueuses, des tiges amères ou encore des argiles qui peuvent influer sur leur santé. Les données scientifiques décrites ici soulignent la diversité et les activités biologiques des items non-nutritifs utilisés par les chimpanzés de Kanyawara en Ouganda et s'enrichissent des témoignages des assistants et du médecin traditionnel local. Leur perception de ces comportements et les recouvrements avec les usages ethnomédicinaux permettent d'explorer le comportement des chimpanzés dans une perspective de comparaison culturelle. Cette étude est aussi l'occasion de souligner l'intérêt - malgré la difficulté inhérente à des observations rares portant sur des individus sauvages - d'une épistémologie du chimpanzé qui doit permettre de mieux appréhender l'acquisition et la transmission des comportements en lien avec la maladie.

The genus Merremia Dennst. ex Endl. (Convolvulaceae) is a rich source of structurally diverse phytochemicals with therapeutic relevance. This review presents the first comprehensive, up-to-date information and research progression on the nutritional value, ethnomedicinal uses, phytochemistry, pharmacological activities, and toxicity of the genus Merremia. Using the key search term “Merremia”, relevant documents and information were retrieved from electronic databases. Relevant documents were uploaded in RStudio with installed bibliometric software packages and used for data retrieval, tabulation, and network visualization. Bibliometric analysis revealed that ca. 55% of the studies related to Merremia were published in the last decade, which can be grouped into four thematic areas: (i) drug formulation, (ii) taxonomy, (iii) chemical analysis, and (iv) treatment of diseases. Ethnomedicinal uses, phytochemistry, and biological activities studies showed that species in the genus are promising medicinal plants with various pharmaceutical potentials. However, clinical studies to validate the efficacy of the reported bioactivities and the mechanisms underlying the various activities are lacking and should constitute a future research focus. Additionally, reports on the nutritional and antinutritional constituents of Merremia species revealed that the species meet high nutritional quality criteria for animals and are therefore suitable for inclusion in livestock diets. The few available investigations on toxicity indicated that most Merremia species are safe for human and animal use but not with prolonged chronic administration.
