“…The ripe fruit of E. uniflora contains flavonoids, which are chemical markers of anti-inflammatory activity. The activity of the experimental dentifrice active component may be directly associated with certain pathways of the inflammatory process because there was a reduction in gingival bleeding but not in biofilm accumulation (25).…”

Eugenia uniflora Dentifrice for Treating Gingivitis in Children: Antibacterial Assay and Randomized Clinical Trial

et al. 2016

School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacterial potential of the dentifrice was tested against oral pathogens (Streptococcus mutans, Streptococcus oralis and Lactobacillus casei). Then a phase-II clinical trial was conducted with 50 subjects aged 10-12 years, with clinical signs of gingivitis. The subjects were randomly assigned to the experimental group (n=25) and control group (n=25), in which participants used the experimental dentifrice and a triclosan-based fluoridated dentifrice (Colgate Total 12(r)), respectively. Clinical examinations assessed the presence of gingivitis (primary outcome) and biofilm accumulation (secondary outcome) using the Gingival-Bleeding Index (GBI) and Simplified Oral Hygiene Index (OHI-S), respectively, at baseline and after seven days of tooth brushing 3x/day. The data were analyzed using paired and unpaired t-test (GBI) and Wilcoxon and Mann-Whitney (OHI-S), with p≤0.05. The experimental dentifrice showed efficient antibacterial activity in vitro. In the clinical trial, a significant reduction in gingival bleeding was observed in both experimental and control groups (p<0.0001), with no statistical difference between them (p=0.178), although a small size effect was observed. Biofilm accumulation was only reduced in the control group (p=0.0039). In conclusion, E. uniflora dentifrice showed anti-gingivitis properties in children aged 10-12 years. Thus, it may be a potentially efficient and safe product to be used alternatively in preventive dental practice

Rheological behavior of Brazilian Cherry (Eugenia uniflora L.) pulp at pasteurization temperatures

et al. 2013

The rheological behavior of Brazilian Cherry (Eugenia uniflora L.) pulp in the range of temperatures used for pasteurization (83 to 97 °C) was studied. The results indicated that Brazilian Cherry pulp presented pseudoplastic behavior, and the Herschel-Bulkley model was considered more adequate to represent the rheological behavior of this pulp in the range of temperatures studied. The fluid behavior index (n) varied in the range from 0.448 to 0.627. The effect of temperature on the apparent viscosity was described by an equation analogous to Arrhenius equation, and a decrease in apparent viscosity with an increase in temperature was observed.

“…In Brazil some products based on pitanga are being commercialized such as juices and toiletries (soaps, shampoos, bath oils, body creams and fragrances). The leaves of this plant contain flavonoids, terpenes, tannins and essential oils and the fruits are rich in carotenoids and anthocyanins [31]. It is thus not surprising that preliminary studies have indicated that pitanga can reduce the proliferation of certain types of cancer, such as colorectal, lung, kidney, breast and ovarian cancer [32].…”

Agricultural Biodiversity in Southern Brazil: Integrating Efforts for Conservation and Use of Neglected and Underutilized Species

et al. 2014

Abstract:Brazil is one of the most biodiversity rich countries in the world, including a wealth of agricultural biodiversity in both wild and cultivated forms. This is particularly noticeable in southern Brazil, home to a wide array of underutilized food species whose genetic diversity is maintained mostly by farmers through on-farm management practices. Farmers' contribution in safeguarding and keeping alive traditional knowledge (TK) essential for recognizing, cultivating, valorising and consuming these resources is critical to their conservation. Part of this diversity, a rich basket of native fruits and landraces of vegetables and grains, is also maintained through ex situ collections managed by Brazilian Agricultural Research Corporation (Embrapa) and its partners. This article discusses the integrated efforts for in situ/on-farm and ex situ conservation and use of agricultural biodiversity in southern Brazil. This diversity represents an important cultural heritage, since its use, cultivation and associated knowledge result from the dynamic history of the Brazilian population, including colonisation and immigration by several different ethnicities. Many of these species are sources of genes that convey tolerance to biotic and abiotic stresses, as a result of the combined action of natural selection and artificial selection by farmers in agricultural systems with low inputs and diverse environmental conditions. Due to their importance for food security, use in breeding programs, high nutritional value, and potential for income generation, Embrapa has taken responsibility for the ex situ conservation of these species. The genebanks that safeguard against the loss of these resources do also play an important role in the restoration of this germplasm to farming communities. OPEN ACCESSSustainability 2014, 6 742
