Toxicological and pharmacological effects of Eugenia brasiliensis Lam. (Myrtaceae) leaves in mice.

Eugenia brasiliensis Lam., popularly known as "grumixama" or "Brazilian cherry", is widely used in folk medicine with astringent, diuretic, energizing, anti-rheumatic, and anti-inflammatory properties. Despite its traditional use, detailed toxicological studies of Eugenia brasiliensis are few. Thus, in the current study, we evaluate the toxicological effects of hydroalcoholic extract of Eugenia brasiliensis (HEEb) and its antinociceptive and anti-inflammatory activity. We used male, and female Swiss mice. Acute toxicity study was performed following the Organization for Economic Cooperation and Development (OECD) guideline 425, and subacute toxicity was assessed following OECD guideline 407. We observed behavioral responses, in addition to hematological, biochemical, and histological evaluations. The antinociceptive and anti-inflammatory activity of HEEb were assessed using the Carrageenan-induced mechanical allodynia and paw edema model. Mechanical allodynia, levels of inflammatory cytokines, and oxidative damage were evaluated. The treatment with HEEb was not able to generate important toxicological alterations. Moreover, doses of 100 and 300mg/kg of HEEb were able to reduce mechanical allodynia, paw edema, and inflammatory cytokines (TNF-α, IL-1β, and IL-6), decrease malondialdehyde and increase superoxide dismutase enzyme activity in the paw. This study demonstrated that HEEb does not present important toxic effects. Additionally, an important antinociceptive, anti-inflammatory, and antioxidant potential were observed.

Phenolic profiles, phytochemical composition and vitamin C content of selected horticultural produce from Central Queensland

The Central Queensland region of Australia is a large producer of horticultural produce; however, there are limited studies on the phytochemical composition of the produce from this region. Additionally, some crops or cultivars are poorly known in domestic markets; hence are currently only grown for niche markets. There is opportunity to expand production of these crops if they contain higher levels of health-benefiting compounds compared to existing cultivars. Hence this work aimed to elucidate the phytochemical composition of such under-marketed and/or under-utilised crops, including their phenolic acid and flavonoid profiles. The samples included nine cucurbits, two citrus fruits, dragonfruit and Brazilian cherry. The vitamin C (ascorbic acid) content was quantified using high-performance liquid chromatography with diode array detection, while the phenolic profiles were gathered using targeted liquid chromatograph tandem mass spectrometry analysis. Antioxidant activity was quantified using the FRAP and CUPRAC assays, while total phenolic content was measured using the Folin-Ciocalteu assay. The results revealed extensive variation in the levels of health-benefiting compounds between the samples. The phenolic profiles of several species/cultivars are reported for the first time. The highest ascorbic acid content was found in blood orange skin (817 mg/100 g DW), while the highest total phenolic content was found in blood orange skin (1988 mg GAE/100 g). Samples showing high antioxidant capacity included blood orange skin, Brazilian cherry and spaghetti squash. These results may support the prospect of marketing several of the crops/cultivars as functional food crops in domestic or export markets.

Facial Biocosmetics Based on Natural Dyes from Amazon Wood Residues

ABSTRACT The occurrence of several flavonoids with antioxidant and anti-inflammatory potential properties in wood may have a viable application in the biocosmetic industry. This paper studies the technical viability of redirecting wood residues of the main commercialized Amazonian species, Dipteryx odorata (cumaru), Manilkara huberi (ironwood), Hymenaea courbaril (Brazilian cherry) and Handroanthus serratifolius (yellow ipe), to obtain natural dyes for facial biocosmetics development. For each dye sample, phytochemical profile of phenolic compounds and the total flavonoids content expressed in rutin and quercetin (ug mL–1) was determined. Wood residues extract yield was 6.5% for cumaru, 8.1% for ironwood, 16.3% for Brazilian cherry and 8.8% for yellow ipe. The physical-chemical properties were compliant with the official compendia. TLC-analysis revealed the presence of flavonoids (quercetin) and hydrolyzable tannins (gallic acid). Concentration of total flavonoids content expressed in rutin and quercetin varied between 0.106 to 7.5 and 0.1 to 3.12ug.mL–1, respectively, for all species. Facial biocosmetic formulations with organoleptic properties (appearance, color and odor) suitable for facial use could be obtained from ironwood, Brazilian cherry and yellow ipe dyes. Therefore, Amazon species wood residues reuse is an innovative and sustainable technological strategy to add value to bioproducts of Amazon biodiversity, contributing to the region’s socio-economic development.

In vitro germination and controlled release fertilizer effects on ex vitro development of Eugenia uniflora L. plantlets

AbstractBackgroundEugenia uniflora L (Myrtaceae) is a native shrub from Brazil and is used in traditional medicine and also in the food industry to produce different types of juices, jellies, ice cream, and can also be consumed unprocessed. This species is propagated by seeds, which have irregular germination leading to low producer orchards affecting its economic viability for large‐scale production and the quality of seedlings. Thus, the main goal of this study was to evaluate different in vitro germination conditions and the effects of substrate and fertilizer on ex vitro plantlets development.ResultsSeeds germinated in MS0 under light had the highest speed germination index (1.63). The highest root system length was observed in seeds cultivated in MS + 1 μmol GA3 in the presence of light (12.85 cm). Plantlets developed under MS + 1 μmol GA3 in the presence of light, showed the highest dry weight mass (29.7 mg). The three‐way ANOVA indicated that the type of fertilizer, culture medium, and light conditions separately showed significant effects on shoot length (p < 0.0001, 0.0278, and 0.036 respectively), root collar diameter (p < 0.0001, 0.0428, and 0.0165, respectively) and also for the fresh and dry weight of the shoot, just by the type of fertilizer (p < 0.0001) and culture medium (p < 0.05) used.ConclusionIt was concluded that MS0 under light is the most suitable condition for Brazilian cherry germination and commercial substrate plus the controlled release NPK 15‐9‐12 fertilizer provides better plant growth.

Phytochemical screening, total phenolics and antimicrobian action from the brazilian cherry, black mulberry and blueberry fruits’ pulps

The demand for functional foods with exotic flavors is emerging among consumers. The fruits brazilian cherry, black mulberry and blueberry have demonstrated considerable potential as inhibitors of the growth of microorganisms. The phytochemicals present in different extracts were obtained from fruits (pulps), employing specific tests to detect classes of compounds besides Infrared. Tests were realized for antimicrobial activity and quantification of total phenolics. In the phytochemical tests, the presence of mainly the flavonoid group was observed, in agreement with the high values of total phenolics found. The 70% ethanol is the most indicated solvent because it presents greater extraction of polar clusters, besides providing signals of absorption of O-H bonds in all pulps studied. The blueberry showed fungistatic action for Candida tropicalis. The diffusion of the extract through the culture medium is difficult, consequently, the formation of a halo, visible as that of the control, too is difficult. Therefore, results obtained in this study are considered screening and not as definitive results.

Eugenia uniflora L. Silver and Gold Nanoparticle Synthesis, Characterization, and Evaluation of the Photoreduction Process in Antimicrobial Activities.

Eugenia uniflora linnaeus, known as Brazilian cherry, is widely distributed in Brazil, Argentina, Uruguay, and Paraguay. E. uniflora L. extracts contain phenolic compounds, such as flavonoids, tannins, triterpenes, and sesquiterpenes. The antimicrobial action of essential oils has been attributed to their compositions of bioactive compounds, such as sesquiterpenes. In this paper, the fruit extract of E. uniflora was used to synthesize silver and gold nanoparticles. The nanoparticles were characterized by UV–Vis, transmission electron microscopy, elemental analysis, FTIR, and Zeta potential measurement. The silver and gold nanoparticles prepared with fruit extracts presented sizes of ~32 nm and 11 nm (diameter), respectively, and Zeta potentials of −22 mV and −14 mV. The antimicrobial tests were performed with Gram-negative and Gram-positive bacteria and Candida albicans. The growth inhibition of EuAgNPs prepared with and without photoreduction showed the important functional groups in the antimicrobial activity.

Brazilian cherry: identifying local knowledge and diversity of Eugenia involucrata in the countryside of Santa Catarina state/Brazil

Background: Eugenia involucrata (cerejeira do mato) is a fruit species from the Atlantic Forest Biome, which presents several potential uses; however, it is considered an endangered species. An ethnobotanical survey and physical-chemical evaluations were carried out in order to characterize the local knowledge about E. involucrata, the variability maintained by local communities and identify fruits with agronomic traits of interest. Methods: The study was conducted in the counties of Curitibanos, Frei Rogério, and Rio das Antas. Ethnographic research was used to gather ethnobotanical knowledge. Fruit samples from seven plants owned by family units were evaluated for diameter, height, pH, vitamin C, titratable acidity, and total soluble solids. Results: Nineteen family units were interviewed, where eleven use purposes and fifteen agricultural management practices were mentioned for Eugenia involucrata. The main criteria indicated by people interviewed for E. involucrata selection were “sweeter fruits,” “darker fruits” and “larger fruits.”. There was variability among the seven accessions of E. involucrata evaluated. The accessions 3.D, 4.MI, 5.MII and 6.G were the ones that best met the selection criteria. The affective bond, related to familiar or childhood traditions has contributed to the conservation of E. involucrata. Conclusions: The family units interviewed share a cultural relationship with E. involucrata, which has been perpetuated over generations through the continuous use of the species. Among the genetic variability maintained by the family units, the accessions 3.D, 4.MI, 5.MII and 6.G were those which best attend the selection criteria established. Keywords: cerejeira do Rio Grande, on-farm conservation, ethnobotany.

Biological activity and chemical composition of native fruits: a review

Brazilian native fruit trees have great potential for their use in the food and pharmaceutical industries. Among these, the Myrtaceae family stand out for the diversity of known native fruits, as the case of “araçazeiro” or cattley guava [Psidium cattleianum], “pitangueira”, Suriname cherry or Brazilian cherry [Eugenia uniflora], “guabijuzeiro” [Myrcianthes pungens], “guabirobeira” [Campomanesia xanthocarpa] and “uvalheira” [Eugenia pyriformis]. These fruits contain substances of nutritional and potentially functional importance, including dietary fiber, vitamins (especially A and C) and minerals (potassium, iron, manganese, magnesium, calcium, phosphorus), as well as antioxidant compounds, such as phenolics and carotenoids. The consumption of fruits rich in bioactive compounds and high antioxidant activity has the potential to prevent chronic non-communicable diseases such as cancer, diabetes mellitus, dyslipidemias, cardiovascular diseases, and chronic respiratory diseases. For example, Suriname cherry and cattley guava fruit extracts showed anti-hyperglycemic, antidyslipidemic and antioxidant effects in animal models with insulin resistance, cattley guava also showed anticarcinogenic, antimicrobial, anti-inflammatory and anti-aging activities. “Uvaia” has a promising effect as an antimicrobial agent. In this review, summarized information on the main native fruits of the Myrtaceae is presented, highlighting their composition and biological activities in order to direct new research.

Mini scale production of Brazilian Cherry Fruits (Eugenia uniflora L.) for the first time in NSTU campus in Bangladesh & the determination of antioxidant activity of different solvent extracts of ripe and non-ripe Brazilian Cherry Fruits

The aim of this research is to cultivate Brazilian Cherry Fruits (Eugenia uniflora L.) Plants in NSTU (Noakhali Science and Technology University) Campus, Noakhali, Bangladesh for fruits production and to determine the qualitative antioxidant test, antioxidant activities and total phenolic content of different solvent extracts (Water, Methanol and Ethanol) of Ripe Brazilian Cherry Fruits in Red Color and compare those activities with non-ripe Brazilian Cherry fruits in Green color. The qualitative antioxidant test was determined by simple TLC method and antioxidant activity was determined by DPPH radical inhibition method while the total phenolic content was determined by Folin-Ciocalteu method. The result of the qualitative determination of Antioxidant test indicated that all extracts of Brazilian Cherry Fruits contain high antioxidant compounds. Among the analyzed fruits of all extracts, in both Ripe and Non-Ripe stage, the water extract of non-ripe Brazilian Cherry Fruits (BC-GC-W) showed the highest DPPH radical scavenging activity (73.66%) and showed the lowest IC50 of DPPH scavenging activity (1.01 µg/ml) which may be due to the presence of high content of Vitamin C. Among all extracts of Ripe and non-ripe, the methanol extract of non-ripe Brazilian Cherry Fruits in Green Color (BC-GC-M) was found to be highest total phenolic content 111.52 mg GAE/100g, and the ethanol extracts of Ripe Brazilian Cherry Fruits in Red Color (BC-RC-E) was found to be lowest total phenolic content, 106.004 mg GAE/100g.The overall results that were obtained in this study will be one of the important key strategies by adding this fruits in the diet chart to prevent and fight against infection recently caused by COVID-19 in worldwide and other infectious diseases by increasing our body immunity in the long term and this fruits also will be useful as a raw materials in the pharmaceutical and food industries to prepare drugs and food products.

Is the endophytic fungus Neofusicoccum kwambonambiense another brick in the wall of the post-harvest pathogenic fruit fungi system?

Entophytic fungi are characterized as microorganisms that colonize plant tissues without causing infection symptoms. These organisms are sources of genetic and biochemical diversity for numerous applications, from the production of pharmaceutical compounds to foods. However, many of these fungi can become pathogenic to plants if they find suitable substrate for their infection and development. Neofusicoccum spp. has been considered a phytopathogenic fungus for many agricultural crops, being aggressive for some of them both in their woody parts or fruits, either while still in the orchards or after being harvested. The identification and pathogenicity of the isolates are two important aspects for their characterization. Thus, the objective of this work was to characterize the pathogenicity of two endophytic isolates of the fungus Neofusicoccum sp. in different fruits in the post-harvest process. Therefore, isolates identity confirmation was obtained using Bayesian reconstruction of the internal transcribed spacer region (ITS) and translation elongation factor 1-alpha (TEF 1-α). Subsequently, the isolates were inoculated in zucchini, banana, persimmon, green beans, guava, orange, apple, melon, papaya and tomato, followed by a 10-day evaluation in order to calculate the areas under the disease progress curve. Phylogenetic reconstruction allowed identification of two isolates of the endophytic fungus of Brazilian cherry leaves as Neofusicoccum kwambonambiense, which were confirmed as pathogenic for the following fruits: Brazilian cherry, papaya, tomato, banana and apple, with variations in aggressiveness. However, no infections were found in zucchini, melon and guava by any of the isolates. This is believed to be the first occurrence of N. kwambonambiense isolated from plants of Eugenia uniflora, with pathogenicity in different post-harvest fruits.

Chemical variability of essential oils of Eugenia uniflora L. genotypes and their antioxidant activity.

Eugenia uniflora, known as the "Brazilian cherry", is an economically important neotropical Myrtaceae in the cosmetics and pharmaceutical industries due the production of essential oils with antioxidant activity. On account of its significant genetic variability, genotype evaluations are needed in order to identify genetic features related to the essential oil production that meet the industry requirements. The main objective of the present study was to evaluate the yield, composition, and antioxidant activity of essential oils isolated from the leaves of 36 genotypes of E. uniflora. Essential oil samples were obtained by hydrodistillation, and their composition was determined by gas chromatography coupled with mass spectrometry. A variation of 0.22% to 1.68% in the essential oil yield was observed, in which 78 compounds, namely oxygenated sesquiterpenes, were identified. According to the cluster analysis of the major compounds, six groups were revealed. The observed diversity demonstrates the genetic variability of the species. Also, the antioxidant activity was affected by the composition of the essential oils, ranging from 176.66 to 867.57 µM TEAC.

A Polyphenol-Rich Fraction from Eugenia uniflora Exhibits Antioxidant and Hepatoprotective Activities In Vivo.

Leaves from Eugenia uniflora, the red Brazilian cherry, have a high content of flavonoids that possess several biological effects such as anti-inflammatory, antioxidant, and antidiabetic activities. However, their influence on carbon tetrachloride (CCl4)-induced acute liver injury in rats has not been investigated. In the current study, a bioguided fractionation assay revealed that the ethyl acetate fraction (EAF) of Eugenia uniflora is the safest and most active fraction. LC-MS analysis of the ethyl acetate fraction revealed 22 secondary metabolites, mainly myricetin and quercetin derivatives. EAF did not show toxicity up to 2000 mg/kg, and exhibited antioxidant activities in vitro in DPPH assay with IC50 of 3.35 µg/mL. Additionally, EAF exhibited substantial antioxidant activities in vivo by counteracting the oxidative damage of the prooxidant juglone [80 µM] in Caenorhabditis elegans model organism and increased its survival rate in a dose-dependent fashion through the DAF-16/Foxo pathway. Furthermore, the hepatoprotective activity of EAF (200 mg/kg against carbon tetrachloride (CCl4) intoxicated male Wistar rats was assessed. EAF significantly inhibited CCl4-induced elevation of alanine aminotransferase (ALT), aspartate transaminase (AST), total bilirubin (TB), total cholesterol (TC), and triglycerides (TG), in the blood serum and prevented lipid peroxidation and restored superoxide dismutase (SOD) activity and glutathione (GSH) content in liver tissues. The observed hepatoprotective effects of EAF, which were supported by histopathological observations as pretreatment with EAF, effectively attenuated the CCl4-induced histopathological changes. In conclusion, EAF of Eugenia uniflora leaves has substantial hepatoprotective activities against CCl4 induced acute liver injury in rats due to its antioxidant activity.

Chemical profiling of secondary metabolites of Eugenia uniflora and their antioxidant, anti-inflammatory, pain killing and anti-diabetic activities: A comprehensive approach

Ethnopharmacological relevanceThe red Brazilian cherry, Eugenia uniflora, is widely used in traditional medicine. The aim of this study was to investigate the phytochemical composition of a methanol extract from leaves of E. uniflora and characterization of the isolated compounds. In addition, we aimed to determine the antioxidant activities in vitro and in a cell-based (HaCaT cell) model. We also studied the anti-inflammatory, analgesic, antipyretic and antidiabetic activities in relevant rat models. The molecular mode of action of the antidiabetic activities was also investigated. Materials and methodsUV, MS, and NMR (1H, 13C, DEPT, COSY, HMQC, and HMBC) were used to identify the secondary metabolites. Antioxidant effects were determined in vitro and in HaCaT cells. The ani-inflammatory and antidibetic activities were studied in experimental animals. ResultsIn this work, a new compound, gallic acid 3-O-[6′-O-acetyl-β-D-glucoside], along with 16 known plant secondary metabolites (PSM) were isolated, characterized using UV, MS, and NMR (1H, 13C, DEPT, COSY, HMQC, and HMBC). Noticeable antioxidant effects were determined in HaCaT cells: The extract reduced the elevated levels of ROS and p38 phosphorylation and increased the reduced glutathione (GSH) content induced by UVA. The extract showed substantial anti-inflammatory activities in vivo: It diminished the edema thickness in carrageenan-induced hind-paw edema rat model and lowered the leukocyte migration into the peritoneal cavity. In rats, central and peripheral anti-nociceptive properties were also observed: The extract reduced the number of writhing in acid induced writhing and increased the latency time in hot plate test. Furthermore, adequate antipyretic effects were observed: The extract reduced the elevated rectal temperature in rats after intraperitoneal injection of Brewer's yeast. Moreover, the extract possessed robust anti-diabetic activity in streptozotocin (STZ) -diabetic rats: It markedly reduced the elevated serum glucose and lipid peroxidation levels and increased the insulin concentration in serum with higher potency than the positive control, glibenclamide. These effects might be associated with the interaction of PSM with the conserved amino acid residues of human pancreatic α-amylase (HPA), maltase glucoamylase (MGAM-C) and aldose reductase (ALR2) revealing considerable binding affinities. ConclusionA plethora of substantial pharmacological properties indicates that Eugenia uniflora is a good antioxidant and a sustainable by-product with solid therapeutic potential for treating diabetes, inflammation, pain and related oxidative stress diseases.

EFEITO IN VITRO E IN VIVO DE EXTRATOS DE Eugenia uniflora EM NEMATÓDEOS GASTRINTESTINAIS DE OVINOS

Resumo Este estudo avaliou a ação in vitro e in vivo de extratos de Eugenia uniflora em nematódeos gastrintestinais de ovinos. No teste de inibição da eclodibilidade dos ovos, extratos aquosos e hidroalcoólicos foram testados nas concentrações de 40 a 1,25 mg/mL. O efeito citotóxico foi mensurado através do ensaio de MTT em células VERO nas concentrações de 4000 a 1,95 µg/mL. A composição química foi analisada através da marcha fitoquímica qualitativa. No teste in vivo, foram administrados 100 mg/kg, por via oral, do extrato hidroalcoólico por três dias em ovinos naturalmente infectados e realizada coleta de fezes para estimar a redução de ovos por grama de fezes (OPG). Diferentes extratos de E. uniflora inibiram a eclodibilidade dos ovos, com percentual de inibição variando de 14,56 a 99,75%, sendo os hidroalcoólicos mais promissores que os aquosos. Na marcha fitoquímica, compostos com ação anti-helmíntica comprovada foram observados, como flavonoides, saponinas, taninos e triterpenos. Nas condições testadas, os extratos apresentaram citotoxicidade nula a moderada. In vivo, a redução do OPG foi observada apenas no grupo controle (anti-helmíntico). Os extratos de E. uniflora mostraram-se promissores com ação in vitro, necessitando estudos que avaliem outras concentrações e formas de administração in vivo.

Advances in the propagation of Brazilian Cherry tree

Abstratct Brazilian Cherry tree is a native fruit tree belonging to the Myrtaceae family, with ample adaptation to the different edaphoclimatic conditions of Brazil, which makes this fruit widely known. However, there are still few commercial orchards, which may soon be reversed, since studies have shown the benefits of the consumption of this fruit for human health, as well as the potentialities for industrial processing. Thus, Brazilian Cherry tree will no longer be a backyard plant and will be grown in commercial orchards, which demands the production of seedlings with genetic quality. Sexual propagation with the use of seeds should be replaced by asexual propagation by means of cutting, grafting, spreading and tissue culture. The grafting method has proven to be efficient in more than 70% of cases and herbaceous cuttings have rooting greater than 77%. New studies on micropropagation and better control of herbaceous cutting processes should stimulate and economically increase the commercial production of this fruit for fresh consumption or processing. This review article included the results of other studies, addressing advances, limitations and protocols for propagation of Brazilian Cherry tree.

<b>Allelopathic bioactivity of fresh and infused aqueous extracts of Brazilian cherry (<i>Eugenia uniflora</i> L.) on lettuce and maize

This study aimed to analyse the allelopathic bioactivity of fresh and infused aqueous extracts of Brazilian cherry leaves on the germination of lettuce and the initial development of maize. Brazilian cherry leaves were used to prepare a fresh aqueous extract (200 g L-1) and an infused extract (100 g L-1), which were diluted to concentrations of 0.4, 0.8, 1.2, 1.6 or 2.0% w/v. The variables evaluated in lettuce were the germination rate (GR), germination time index (GTI), germination speed index (GSI) and root length (RL). To determine the effect on the initial development of maize, we measured the shoot (SL) and root (RL) length. The experimental design included a factorial 2 × 5 design (two extracts and five concentrations), in addition to a control treatment (no extract). In general, the allelopathic bioactivity differed between the fresh and infused extracts. The fresh extract was more phytotoxic for the GR and RL of lettuce. Some beneficial results were observed for the infused extract, including an increase in the RL of lettuce and SL of maize. These effects were dependent on the extract concentration. Thus, there is evidence that Brazilian cherry extracts have allelopathic bioactivity.

Forest inventory and the genetic diversity of the remaining fragment of Hymenaea courbaril L.

ABSTRACT Hymenaea courbaril is a rare species in the riparian areas of the state of Sergipe, Brazil. This species is known as Brazilian cherry or Brazilian copal and it occurs in fragments of the Rainy Forest and in the transition zones between the Rainy Forest and the Caatinga Biomes. This work was carried out, in order to quantify the genetic diversity of the remaining population of Brazilian cherry, by RAPD markers. In a studied area of 100 ha in the low course of the São Francisco River, only 15 individuals were observed. The analyzed parameters were as follows: Jaccard’s genetic similarity, the number of observed alleles, the number of effective alleles, the genetic diversities of Nei, the percentages of the polymorphic loci, the genetic diversities when using the Shannon index and the coancestry coefficient. There was no correlation between the genetic distances and the geographical distances. Despite the low number of individuals, high genetic diversity was observed, a fact that contributes to the development of strategies for the conservation of the species.
