Abstract:

This paper presents the experimental study of physico-chemical properties of Simarouba methyl ester and diesel blends at the different temperatures and with varying volume percentage of Simarouba methyl ester in the blend. Blends are prepared adding different volume fraction of Simarouba methyl ester to neat diesel. The percentage of Simarouba methyl ester added to diesel is 10% to 90%, the prepared blends are stirred well for mixing of methyl ester and diesel. The prepared blends are kept in closed container for 24 hours for observation of separation of blends. It is observed that there is no separation of Simarouba methyl ester and diesel. Experiments are carried out to find density, kinematic viscosity, flash point and heating value of blends. These properties are investigated using standard equipments with standard procedure. Viscosity is determined by using standard Red-Wood viscometer with standard procedure of methyl ester and diesel blends at different temperatures. It is observed that as volume fraction of Simarouba methyl ester increases in the blend density, kinematic viscosity, flash point increases and heating value decreases. The percentage decrease in kinematic viscosity is more at lower temperature compared to higher temperature. Correlations for estimation of viscosity and density of blends at different temperatures are proposed.

Abstract:

ABSTRACTLight environment, leaf physiological characteristics, and growth were compared for forest-grown saplings of three species of tropical trees with known life histories. Light environment was assessed both by hemispherical canopy photography and a quantitative visual index of crown illumination. Leaf gas exchange characteristics were measured by infrared gas analysis. The species tested included Lecythis ampla, a species tolerant of understorey conditions, Pithecellobium elegans, a species found in relatively bright sites, and Simarouba amara, a fast-growing, light-demanding species.Annual height and diameter growth did not significantly differ between the three species, but highest average rates were found for Simarouba. Likewise, saplings of the three species were found in similar low light environments although Simarouba saplings were found in slightly brighter sites and Lecythis saplings were found in the lowest light environments. Despite similar light regimes, the species differed markedly in leaf area and gas exchange. Leaf areas of Lecythis saplings were five and ten-fold greater than Simarouba and Pithecellobium saplings, respectively. Light-saturated leaf photosynthesis and leaf dark respiration rates of Lecythis were about half those of Simarouba; rates of Pithecellobium were intermediate. Lecythis had the highest leaf photosynthesis at understorey diffuse light levels. Measures of annual growth were positively correlated with estimates of both direct and diffuse light with the strongest correlations between sapling performance and diffuse light.

Abstract:

Prior knowledge about the physiological behavior of seeds under storage conditions allows the use of appropriate techniques to maintain viability. The goal of the present study was to classify the behavior of Simarouba amara seeds regarding their physiological potential during storage. The seeds were obtained from mature fruits, collected from five parent plants located at the Joanes-Ipitanga Environmental Protection Area (EPA) (Simões Filho, Bahia) in January 2018. Two experiments were carried out in a completely randomized design. In the first one, seed desiccation tolerance was evaluated with seven moisture contents: 5%, 7.5%, 10%, 12.5%, 15%, 25% and 35.6% (initial moisture). A germination test was carried out to evaluate the seeds’ vigor. In the second experiment, the seeds were stored with moisture contents of 7.5%, 12.5% and 35.6% at temperatures of 8 °C, 15 °C and 20 °C) for two storage periods, two and four months, and samples were taken to determine moisture content and conduct the germination test. Germination tests were performed in BOD chambers at 30 °C and with 12-hour light photoperiod. Daily counts were performed for the number of germinated seeds. We measured germination percentage, mean germination time, uncertainty index, percentage of normal seedlings, and percentage of unviable seeds. Simarouba amara seeds tolerate desiccation up to 7.5% moisture content, but lost viability when stored under this condition. At four months of storage all seeds lost viability. Simarouba amara seeds are recalcitrant and lose viability before reaching two months of storage.

Abstract:

Species of the genus Simarouba have been studied because of their antimalarial and antileukemic activities. A group of oxygenated terpenes called quassinoids have been isolated from species of the Simarouba genus, and are responsible for its therapeutic properties. We hypothesized that Simarouba tulae, an endemic plant from Puerto Rico, is a natural source rich in quassinoid compounds with anticancer activity. The leaves were processed and extracted with solvents of different polarities. The extracts were screened for their antiproliferative activity, and it was shown that the chloroform extract was the most active extract. This extract was purified using different chromatographic techniques to afford the quassinoid simalikalactone D (SKD). This compound was further characterized using NMR and X-ray diffraction analysis. A reassessment of original structural assignments for SKD is proposed. SKD showed high cytotoxicity activity, with an IC50 of 55, 58, and 65 nM in A2780CP20 (ovarian), MDA-MB-435 (breast), and MDA-MB-231 (breast) cell lines, respectively. Exposure to SKD led to 15% inhibition of the migration of MDA-MB-231 cells.

Abstract:

Cancer is becoming a high-profile disease throughout the world and for its treatment most prevalent technique is chemotherapy which has its limitations due to many toxic or side effects on healthy or non-cancerous body parts. Therefore, there is a demand for alternative and supportive anticancer agents for treatments which are naturally-derived with minimal side effects. This review paper highlights the therapeutic importance, safety, and efficacy of the Laxmi Taru along with their active constituents used either as single plant-decoctions, extracts, or in combinations especially in some traditional herbal medicines. World Health organization (WHO) is promoting this concept as ‘Save plants to save lives.’ Among the key health issues, WHO have also said that, cancer is the second leading cause of death globally. The plethora of secondary metabolites (therapeutic agents) found in the plant are the rich source to find the alternative safe anti-cancer agents.

Abstract:

The importance of Simarouba versicolor St. Hil. fruit dispersal by the leaf-cutting ant Atta sexdens (L.) was studied in the Cerrado, Tocantins, Brazil. The trees and nests were located between a forest area and a Brachiaria decumbens Stapf pasture. Seeds were collected in October 2015 along foraging trails and on the anthill of an A. sexdens colony. Germination of three groups of seeds was tested: (1) seeds with the tegument removed by the ants; (2) seeds without tegument, cleaned manually, and (3) seeds with tegument. The germination rates for the three treatments were similar; however, it was verified that the seeds cleaned by ants germinated faster. In addition, it was verified that the ants dispersed the seeds by at least 20 meters in the study area. Simarouba versicolor is a plant studied for its insecticidal properties, and this is the first study to our knowledge reporting its dispersal by ants.

Abstract:

Capsicum annuum L. is an edible vegetable crop while Simarouba glauca L. is a medicinal plant. The study was taken up to evaluate the antibacterial activity of these extracted plant materials against Streptococcus mutans and Streptococcus sobrinus, the main dental caries agents. Three plant materials (fruit, seeds and leaves) of Capsicum annuum L. var. baydagi dabba and two plant materials (leaves and bark) of Simarouba glauca L. were collected in the month of November and February, respectively. The plant materials were cleaned, dried and prepared for extraction. The antibacterial susceptibility testing was performed using disc diffusion method. At maximum concentration of 100 mg/ml, it was observed that both the extracted plant materials did not possess antibacterial activity against S. mutans and S. sobrinus. The study revealed the lack of antibacterial activity of C. annuum and S. glauca against S. mutans and S. sobrinus.

Abstract:

In the present study, the supercritical carbon dioxide (CO2) extraction of oil from Simarouba gluaca seeds was carried out at varying conditions of pressure (300–500 bar), temperature (50–70 °C) and CO2 flow rate (10–30 g·min-1). The extraction condition for maximum oil yield was obtained at 500 bar pressure, 70 °C and at 30 g·min-1 flow rate of CO2. The extracted oil was analyzed thoroughly for physico-chemical properties and compared with those of conventional solvent extracted oil. An interesting observation is a significant reduction in the phosphorus content of the oil (8.4 mg·kg-1) extracted using supercritical CO2 compared to the phosphorous content of the solvent extracted oil (97 mg·kg-1). Moreover, the content of total tocopherols in supercritically extracted oil (135.6 mg·kg-1) was found to be higher than the solvent extracted oil (111 mg·kg-1). The rest of the physico-chemical properties of the two differently extracted oils matched well with each other. The results indicated the possible benefits of supercritical CO2 extraction over solvent extraction of Simarouba gluaca seed oil.

ABSTRACT Aim The aim of this study was to assess the antimicrobial activity of Simarouba glauca plant extract as intracanal medicament against Enterococcus faecalis and to compare its effect with that of metapex (calcium hydroxide with iodoform paste). Materials and methods In the study, 30 human premolar teeth infected with E. faecalis were used. Contaminated teeth were randomly separated into three groups (n = 10) and treated as follows: Group I, calcium hydroxide-based medication; group II, S. glauca-based medication; and group III, contaminated teeth without medication. After 7 days of treatment, teeth from each group were assessed for the level of microbial growth after a period of treatment. Results Metapex and S. glauca were associated with a reduction in E. faecalis after removal of the dressing; however, saline is associated with an increase in colony-forming units (CFU) per milliliter. Conclusion In this laboratory study using extracted teeth, S. glauca (Lakshmi Taru) was able to significantly reduce the CFU per milliliter values of E. faecalis in the root canal system similar to metapex.

Abstract:

Biolubricants are renewable, biodegradable, nontoxic, and have zero greenhouse gases. In this work, the tribological properties of the Simarouba glauca biodiesel (SBD) are studied with nanoparticles as additives. Nanoparticles of copper oxide (CuO) and silicon dioxide (SiO2) were added with 0.2, 0.5, 0.75, and 1% weight (wt) in the base SBD. The coefficient of friction (COF) and the wear scar diameters (WSD) were evaluated using four ball tester for the test conditions as per ASTM D 4172 standard. The morphologies of the worn surfaces were inspected by scanning electron microscope (SEM). The addition of nanoparticles improved the friction and wear characteristics of SBD. A combination of abrasive and adhesive wear was evident. The average COF for pure SBD was 0.0168. The results indicated that 0.75% and 0.2% of CuO nanoparticles as a beneficial percentage in the base oil exhibiting the lowest COF and WSD. CuO nanoparticles proved to be superior to SiO2 nanoparticles as additives in SBD, demonstrating 8% and 60% decrease in wear and friction parameters, respectively.

Abstract:

RESUMO A pressão concentrada em pequeno grupo de espécies tropicais torna necessário maior investimento em estudos e técnicas de melhoramento em espécies menos conhecidas na tentativa de direcioná-las para usos múltiplos. Este trabalho tem por objetivo avaliar a influência do tratamento termomecânico nas propriedades colorimétricas e no modulo de elasticidade da madeira de marupá, com a finalidade de utilizá-la no segmento de pisos. Os resultados mostraram uma mudança significativa, com efeito da temperatura na cor e na propriedade de elasticidade da madeira. Em geral, houve uma melhora no módulo de elasticidade dinâmico, enquanto a velocidade variou de acordo com cada tratamento apresentado, tendo-se valores mais baixos para os tratamentos com maior pressão. A madeira escureceu (menores valores L* e maiores valores de a*) com a aplicação da temperatura. As cores da madeira de marupá após os tratamentos, aliadas à propriedade de elasticidade potencializam essa espécie como opção para a indústria de pisos.

Abstract:

Being an energy source of another origin, the compression ignition (CI) engine’s typical design parameters might not suit Simarouba oil methyl ester (SuOME). Present experimental investigation targets are determining the effects of engine design parameters, including fuel injection pressure and nozzle geometry, on the engine, concerning performance and emissions such as carbon monoxide (CO), unburnt hydrocarbon (HC), oxides of nitrogen (NOx), and smoke opacity, with SuOME as fuel. Comparisons of brake thermal efficiency (BTE) and different emissions from the engine tailpipe were performed for different fuel injection pressures and a number of injector holes and diameter of orifices were opened in the injector to find the optimum combination to run the engine with SuOME. It was observed that the combined effect of an increase in injection pressure of 240 bar from 205 bar, and increasing number of injector holes from three to six with reduced injector hole diameters from 0.2 to 0.3 mm, recorded higher brake thermal efficiency with reduced emission levels for the SuOME mode of operation compared to the baseline standard operation with SuOME. For 240 bar compared to 205 bar of injection pressure (IP) for SuOME, the BTE increased by 2.35% and smoke opacity reduced by 1.45%. For six-hole fuel injectors compared to three-hole injectors, the BTE increased by 3.19%, HC reduced by 9.5%, and CO reduced by 14.7%. At 240 bar IP, with the six-hole injector having a 0.2 mm hole diameter compared to the 0.3 mm hole diameter, the BTE increased by 5%, HC reduced by 5.26%, CO reduced by 25.61%, smoke reduced by 10%, while NOx increased marginally by 0.27%. Hence, the six-hole FI, 240 IP, 0.2 mm FI diameter holes are suitable for diesel engine operation fueled by Simarouba biodiesel.

Abstract:

The suitability and profitability of coffee cultivation in Central America are at risk due to pest and disease outbreaks, price fluctuations and climate change. Proper shading is claimed to be one of the most promising practices to seek sustainability and better adapt coffee cultivation to climate change in marginal areas. This study recorded and compared coffee cherry yields over a ten-year period from shaded coffee (N-fixing-trees and timber trees) agroforestry systems under different management regimes (conventional vs. organic) in a suboptimal site. Significant differences in production were detected between conventional inputs vs. combination of organic inputs and shade types in some years of the evaluation period. Full-sun cultivation under intensive management was the most productive system for coffee yields, followed by shaded systems under timber trees. Interestingly, and regardless of management systems (intensive conventional or intensive organic) the worst combinations in terms of coffee yield were shaded systems under leguminous species (Inga laurina (Sw.) Willd. + Simarouba glauca DC.). Across all experimental plots, the timber species Simarouba glauca and Tabebuia rosea (Bertol.) DC. grew well, reaching a mean annual increment in diameter of 2.5-3.3 cm/year (age 12 years). Average gross revenues were higher in full-sun and timber-shaded agroforestry systems. Overall, intensive management regimes were the most expensive cultivation system to run but also the best in terms of coffee yield performance.

Abstract:

The presence of Daceton boltoni in Cotriguaçu municipality, state of Mato Grosso, southern Amazon is reported. Workers of D. boltoni were collected manually in nests on the branches of three Caxeta trees (Simarouba amara Aubl. - Simaroubaceae) from a reforestation area. In the same location where D. boltoni was recorded, Daceton armigerum (Latreille 1802) workers have also been collected, corroborating the hypothesis that these are sympatric species. This is the first record of the occurrence of this species in Mato Grosso state and the second in the Brazilian Amazon.

Abstract:

O trabalho apresenta a fenologia de Simarouba amara Aubl., espécie de Floresta Tropical Úmida de Terra-Firme, na Reserva Florestal Adolpho Ducke (RFAD), Manaus-Am., Brasil. Analisaram-se dados de floração, frutificação e mudança foliar e dados climatológicos obtidos no período de 1970 a 1980. Determinou-se a freqüência, regularidade e duração de três fenofases. Destas, verificou-se que a fase "plena floração" (F2) ocorreu na transição da estação seca para a chuvosa (nov. e dez.), com pico em dezembro; a fase "frutos maduros" (F5) ocorreu na estação chuvosa (fev. e mar.), com pico em fevereiro, enquanto a fase "folhas novas" (F8) ocorreu na estação seca (set. e out.), com pico em setembro. A espécie mostrou característica de ser perenifólia com freqüência de ocorrência das fenofases anual e padrão regular com duração intermediária. A análise não paramétrica de correlação linear de Spearman entre as fases F2, F5 e F8 e as variáveis climáticas mostrou que frutos maduros (F5) teve correlação linear positiva e significativa com a precipitação (r = 0,35; p<0,01); negativa e significativa com a insolação (r = - 0,36; p<0,01) e evaporação (r = - 0,34; p<0,01); folhas novas (F8) teve correlação linear positiva e significativa com a insolação (r = 0,28; p<0,01), evaporação (r = 0,33; p<0,01) e temperatura máxima (r = 0,32; p<0,01); negativa e significativa com a precipitação (r = - 0,26; p<0,01). Por outro lado, não apresentou correlação linerar com a fase plena floração (F2).

Abstract:

ABSTRACT Aim To determine the antimicrobial effect of water extracts of leaves of Annona muricata and Simarouba glauca on Enterococcus faecalis using agar diffusion method. Materials and methods Dried leaves of A. muricata and S. glauca were powdered and extracted in a soxhlet apparatus. Enterococcus faecalis was grown overnight in Trypticase soy agar plates. About 10 μL of each extract was placed on agar plates and incubated overnight. The zone of inhibition was measured after 24 hours. About 1% sodium hypochlorite and distilled water were used as positive and negative controls. Results The leaf extract of A. muricata showed similar effectiveness as that of sodium hypochlorite, whereas the leaf extract of S. glauca showed only a slight reduction in growth of E. faecalis. Conclusion Leaf extract of A. muricata can be developed as an alternative to sodium hypochlorite for root canal irrigants. Clinical significance Success of endodontic treatment depends on complete disinfection of the root canals. Root canal irrigants have a major role in complete disinfection of the root canals. Chemical root canal irrigants are more or less toxic to the oral environment. In this study, naturally derived leaf extracts of A. muricata and S. glauca are compared with sodium hypochlorite for its effectiveness against E. faecalis – the most common pathogen found in the root canals.
