RESUMO

IIn this study, we report the metabolic profiling of several previously uncharacterized Passiflora species native to Brazil, employing molecular networks to delve deeper into chemical constituents. Using the GNPS platform, in silico tools, and substructure annotation techniques, we expanded the chemical annotations. Principal Coordinate Analysis (PCoA) revealed significant metabolic similarities between several species, including P. incarnata, suggesting shared pharmacological potential. Our identification of metabolic compounds facilitated comparisons between understudied species with medicinal properties. Notably, we documented 25 previously uncharacterized species, paving the way for the development of novel products aimed at improving human well-being. This research focused on several native Passiflora species from Brazil, highlighting their unexplored therapeutic potential.

RESUMO

Passiflora cincinnata is a Passifloraceae typical of the Caatinga, a biome unique to Brazil. It has various pharmacological properties associated with its high flavonoid content. Vitexin, isovitexin, orientin, isoorientin and derivatives are the main chemical and pharmacological markers for this plant. Although flavonoids enriched-extracts have been widely applied in phytocosmetics, especially in sunscreen formulations, the use of P. cincinnata as a photoprotective ingredient remains unexplored. Different hydro-alcoholic extracts were prepared and their antioxidant and photoprotective activities were evaluated by in vitro assays. The most promising extract (Pc-1) was analyzed by HPLC-DAD-ESI-MS/MS. Nine flavonoids were identified as major compounds: isovitexin-7-O-glucoside, isoorientin-2"O-hexoside, orientin, isoorientin, isovitexin-2"-O-glucoside, isovitexin-6"-O-glucoside, isoscoparin and isoquercitrin. Finally, Pc-1 (5 and 10%, v/v) was incorporated into gel formulations, alone or combined to commercial chemical filters (benzophenone-3 and octyl methoxycinnamate). Formulations containing Pc-1 showed high SPFspectrophotometric values. When combined to commercial filters, Pc-1 (5%) potentiated their photoprotective efficacy (p<0.05). A physicochemical characterization indicated no incompatibility or signs of instability after extract incorporation. Altogether, these findings encourage the use of Pc-1 as a photoprotective ingredient or co-adjuvant in sunscreens formulations.

RESUMO

The genus Anastrepha contains some of the most important fruit pests in the Americas. It comprises more than 300 species, of which 129 occur in Brazil. The genus is divided into 26 species groups, including the pseudoparallela group with 31 species, whose known host plants are primarily fruits of the genus Passiflora (Passifloraceae). Fourteen species are recorded in Brazil. Here, a new species of Anastrepha reared from fruits of Passiflora actinia Hook. and Passiflora elegans Mast. from southern Brazil is described and illustrated. In addition, a synopsis of the Brazilian species of the pseudoparallela group is provided.

RESUMO

In this study, the oils of açaí, passion fruit, pequi, and guava were submitted to physicochemical analysis to investigate their potential application in the food industry. Gas chromatography associated with mass spectroscopy showed that oleic and linoleic acids are mainly responsible for the nutritional quality of açaí, passion fruit, pequi, and guava oils, which exhibited 46.71%, 38.11%, 43.78%, and 35.69% of the former fatty acid, and 18.93%, 47.64%, 20.90%, and 44.72% of the latter, respectively. The atherogenicity index of the oils varied from 0.11 to 0.65, while the thrombogenicity index was 0.93 for açaí, 0.35 for guava, and 0.3 for passion fruit oils, but 1.39 for pequi oil, suggesting that the use of the first three oils may lead to a low incidence of coronary heart disease. Thermogravimetry showed that all tested oils were thermally stable above 180 °C; therefore, they can be considered resistant to cooking and frying temperatures. In general, the results of this study highlight possible applications of these oils in the food industry, either in natura or in typical food production processes.

RESUMO

In recent years, people have become interested in consuming low-fat foods as this reduces the risk of obesity and cardiovascular disease. For this reason, this study optimized the incorporation of passion fruit epicarp (PFE) as a partial fat substitute in dairy ice cream. For this purpose, a central composite rotational design 22 was performed and 5 response variables were optimized, of which 4 variables were maximized (percentage overrun, hardness, adhesiveness, and color coordinates L*, a*, b*), while the melting rate was minimized as a function of two factors (% PFE and % fat). The stability of three types of ice cream was then evaluated: experimental ice cream (3% milk fat and 0.97% PFE), commercial ice cream (4% milk fat and 2% vegetable fat) and control ice cream (3% milk fat without PFE added), according to their physicochemical and sensory properties during 57 days of storage (-22 °C, 85% relative humidity). The results showed that it was possible to reduce the milk fat by up to 25% by adding PFE (0.97%), which significantly reduced the melting rate and resulted in higher hardness (N), adhesiveness and increased yellowness compared to the commercial samples. The optical microscopy analysis also showed that PFE keeps the air bubbles immobile due to the increased viscosity in the serum phase during the 57-day storage.

RESUMO

Research efforts have been made to develop novel tactics, such as those targeting behavioral control, for management of the Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Psyllidae), vector of the causal agent of citrus Huanglongbing. Here, we investigated whether association of "Ponkan" mandarin (Citrus reticulata) with volatiles from non-host crops: avocado, passion fruit or coffee, alters host location by the Asian citrus psyllid; and whether they can be temporary hosts for the Asian citrus psyllid. In wind tunnel assays, we found that the association of mandarin seedling with avocado plant volatiles reduced in 30% the number of psyllids sitting on host plants compared to the mandarin alone. In contrast, passion fruit plant volatiles facilitated host location by psyllids, which found mandarin seedlings faster than when exposed to mandarin alone. The association with coffee volatiles did not alter the attractiveness of mandarin to the Asian citrus psyllid. Survival and half-lethal time (LT50) of D. citri fed on non-host plants were longer than those insects with water only, but shorter than those fed on mandarin. Among the non-host plants, D. citri performed better in coffee, followed by avocado and passion fruit plants. Our results indicate that the association of mandarin with avocado plant can be beneficial for Asian citrus psyllid management.

RESUMO

The consumption of antioxidants can prevent chronic non-communicable diseases and the exotic Colombian fruits, goldenberry (Physalis peruviana L.) and purple passion fruit (Passiflora edulis f. Edulis Sims), are rich in bioactive compounds. The aim of this work was to characterize and optimize the antioxidant activity of these fruits blend. The fruits were classified according to their maturity stages, the freeze-dried extracts were physiochemically characterized, and polyphenols, carotenoids and antioxidant activity were quantified, and an experimental mixture design was applied to optimize the antioxidant activity of the bend. For the goldenberry the maturity stage 3 had higher iron-reducing capacity and higher content of polyphenols. Meanwhile, for the purple passion fruit, this maturity stage had higher antioxidant activity by all methodologies and a higher concentration of polyphenols; the ultrasound-assisted extraction showed statistical differences for polyphenols, ABTS and FRAP. Antioxidant activity showed significant differences (p < 0.05) between samples (TBARS (3.98 ± 0.14 and 7.03 ± 0.85 µM-MDA/g), ABTS (36.53 ± 2.66 and 29.4 ± 4.88 µMTrolox/g), DPPH (36.53 ± 2.66 and 23.90 ± 0.96µMTrolox/g), ORAC (23.02 ± 0.36 and 32.44 ± 0.94 µM Trolox/g) and total polyphenols (5, 29 ± 0.34 and 9.12 ± 0.37mgGA/g). Some of the carotenoids identified by HPLC-MS in both fruits were lutein, α and ß-carotene, phytoene and lycopene. The optimum bend was goldenberry 0.83 and purple passion fruit 0.17.

RESUMO

Resumen En esta investigación de corte psicométrico se analizó la validez y la confiabilidad de la Escala Triangular de Amor de Sternberg (ETAS) de 45 ítems, en una muestra de 296 personas de la ciudad de Arequipa (ubicada al sur del Perú). El 56.1% fueron mujeres y el 43.9% fueron varones con una edad promedio de 40.7 años. La ETAS tiene tres componentes: Intimidad, Compromiso y Pasión. Para el procesamiento estadístico se aplicó el análisis factorial confirmatorio para analizar la estructura interna y la prueba alfa ordinal para estimar la confiabilidad. Se encontró que la ETAS tiene una estructura de tres factores, luego de eliminar 11 ítems debido a que saturaban en dos o más factores. La escala quedó reducida a 34 ítems, con adecuados índices de bondad de ajuste y una confiabilidad con índices superiores a .93 en cada uno de sus tres factores.


Abstract In this psychometric research, the validity and reliability of the 45-item Sternberg Triangular Love Scale (STLS) was analyzed in a sample of 296 people from the city of Arequipa (located in southern Peru). 56.1% were women and 43.9% were men with an average age of 40.7 years. The STLS has three components: Intimacy, Commitment and Passion. For statistical processing, confirmatory factor analysis was applied to analyze the internal structure and the ordinal alpha test to estimate reliability. It was found that the STLS has a three-factor structure, after eliminating 11 items because they loaded on two or more factors. The scale was reduced to 34 items, with adequate goodness-of-fit indexes and reliability with indexes greater than .93 in each of its three factors.

RESUMO

Although studies aimed at understanding entrepreneurship have analyzed passion, creativity, and entrepreneurial self-efficacy, few studies include these antecedents in the same model. In this sense, this study aims to assess the relationship between passion, self-efficacy, and creativity with entrepreneurial intention. The data was collected through a survey and the questionnaires were applied to university students who formed a sample of 190 respondents, and such data was analyzed using structural equation modeling based on partial least square technique. Regarding our results, the relationship between creativity and entrepreneurial intention has not been confirmed. The multigroup analysis revealed that the level of education influences men's entrepreneurial intention and creativity only influence entrepreneurial intention when mediated by entrepreneurial passion. This study contributes by highlighting the roles of analyzed passion, creativity, and entrepreneurial self-efficacy in entrepreneurs from one of the largest emerging economies in the world. Moreover, it also contributes to academia as it confirms the explanatory power of the Theory of Planned Behavior as a tool to understand the cognitive foundations of entrepreneurship. It also offers a practical contribution by signaling to public policymakers which features should be incentivized to boost entrepreneurship in emerging economies.

RESUMO

Neste artigo analisou-se a relação entre paixão e motivação pela prática esportiva em escolares. Os 173 participantes responderam a um questionário sociodemográfico, à Escala da Paixão e à Escala de Motivação para o Esporte II. Utilizaram-se, na análise dos dados, testes de Kolmogorov-Smirnov, correlação de Pearson e análises de regressão múltipla. Os resultados evidenciaram que a paixão harmoniosa tem associação negativa sobre a regulação externa e positiva sobre a regulação introjetada, identificada e intrínseca. Já a paixão obsessiva apresentou associação positiva sobre a desmotivação e a regulação externa. Concluiu-se que a paixão harmoniosa está associada de maneira positiva com a motivação autônoma e controlada, enquanto a paixão obsessiva, com a motivação extrínseca e a desmotivação (AU).
