Abstract Background:Information on the knowledge, management and ways of using food and medicinal plants by traditional populations, family farmers and Brazilian native population in the Amazon is essential to guarantee the sovereignty of these groups. The objective of this study was to evaluate the diversity, knowledge and ways of using non-conventional food and medicinal plants in traditional communities in a conservation unit in the Brazilian Amazon.Methods:This study was conducted using semi-structured interviews applied to local respondents. Fifty-six residents were interviewed in 26 communities. The Indices of Use Value (UVI) and relative frequency of species citation (Fr) were evaluated; also, their diversity and equitability using the Shannon- Wiener (H’) Pielou (J’) indices, respectively. The species were listed according to their family, scientific name, popular names, categories of use, propagation environment, growth habit, medicinal indications, domestication status, production cycle and herbarium registration.Results:A total of 269 species of both non-conventional food and medicinal plants were identified, distributed in 84 botanical families, 198 genera, in addition to 13 unidentified species. The Arecaceae and Lamiaceae families had the highest species richness (11 and 7, respectively). Eryngium foetidum L. (Apiaceae) and Ipomoea potatoes L. (Convolvulaceae) presented the highest relative citation frequencies (19.7 and 19.3, respectively) and the highest index of use value of the species (0.94 and 0.92, respectively). The Shannon-Wiener (H’) and Pielou (J’) diversity indices were considered high (5.02 and 0.9, respectively) when compared to other ethnobotanical works carried out in Brazil and in the Amazon.Conclusions:A wide relationship of use was observed between the species under study and the population of this conservation area. In the environment in which these families are found, of geographical isolation and distance from urban centers, these species become, in many circumstances, the only food and medicinal resources, therefore, being fundamental to the sovereignty of these families.

The Relationship

Sand-stabilization may exert enormous effects on plant abundance in interdune lowlands in the active sand dune fields. We investigated the plant abundance of 11 interdune lowlands in stabilized and active dunes, respectively, and analyzed the relationship of plant abundance and lowland area. 1) With the enlargement of lowland area, plant abundance of interdune lowlands in stabilized and active dune increased following logarithmic and power functions, respectively. When the area was the same, abundance of stabilized dunes was more than that of active dunes. 2) With the increasing of lowland area in stabilized and active dunes, psammophytes plant abundance relative to the overall plant abundance decreased exponentially. When the area was the same, the percentage in lowlands of active dunes was more than that of stabilized dunes. We concluded that the practice of sand-stabilization could improve plant abundance in interdune lowlands, however, which is at the cost of loss of psammophytes.

Lethality due to dengue infection is a global threat. Nearly 400 million people are affected every year, which approximately costs 500 million dollars for surveillance and vector control itself. Many investigations on the structure-function relationship of proteins expressed by the dengue virus are being made for more than a decade and had come up with many reports on small molecule drug discovery. In this review, we present a detailed note on viral proteins and their functions as well as the inhibitors discovered/designed so far using experimental and computational methods. Further, the phytoconstituents from medicinal plants, specifically the extract of the papaya leaves, neem and bael, which combat dengue infection via dengue protease, helicase, methyl transferase and polymerase are summarized.

We investigated the knowledge of medicinal plants in two areas proposed for the creation of protected areas for sustainable use in the city of Imbituba (SC). In this study, we analyzed the influence of gender, form of learning, and modern medicine on medicinal plant knowledge while also reflecting on the relationship of this knowledge toin situconservation. Data collection was conducted through structured interviews, free listings, guided tours, and collection of botanical material. 197 species of medicinal plants belonging to 70 botanical families were recorded. Gender and the form of learning were factors that significantly influenced the similarity of the knowledge of medicinal plants among the informants. We also observed the existence of a therapeutic pluralism among key informants. Local medicinal plant knowledge emphasizes the importance of strategies to create protected areas of sustainable use as a way to ensure the maintenance of traditional lifestyles and associated local knowledge.

Background: Diabetes mellitus (DM) is a serious public health challenge, projected by WHO to be one of the 7 leading cause of death by 2030. Medicinal plants have been demonstrated to be useful in DM local management because of polyphenols present in these plants. For an alternative treatment approach especially with polyphenols-rich herbs, knowledge of comparative efficacy of the polyphenols will lead to enhanced therapy especially in postprandial hyperglyceamic control. Materials and Methods: Vegetative parts of Anacardium occidentale, Abelmoschus ecsulentus and Ceiba pentandra, prominent in the local management of DM were identified, collected and subjected to alcoholic extraction. From the crude extracts were isolated agathisflavone, quercetin 3-O-glucoside, quercetin 3-O-diglycoside, mangiferin, isomangiferin and pentagalloyl glucose, belonging to flavonoid, xanthones and tannins structural classes. These polyphenols were evaluated for their potentials to inhibit both α-glucosidase and α-amylase. Physicochemical parameters of the polyphenols were evaluated and molecular docking experiments were carried out to gain insight into the observed inhibitory activity. Results: quercetin 3-O-glucosidewas the most potent of the polyphenols against the two enzymes. Increase in the number of phenolic hydroxyl group did not increase the inhibitory activity and neither computation of the binding energies with the enzymes nor physicochemical parameters of the polyphenols could explain the observed inhibitory activity against the enzymes, across the structural classes. Thus, only the bioassay against the enzymes α-glucosidase and α-amylase correlated well with the use of the plants in treating diabetic mellitus Conclusion: Medicinal plants rich in quercetin 3-O-glycoside may have better treatment outcomes in postprandial hyperglycaemia control.
