“…This behavior was similar in all gas concentrations, with no interaction effect between treatments and storage period. In minimally processed plants, injuries in the plant tissue caused by cutting the fruits and/or vegetables lead to an increase of respiratory rate and ethylene production, causing a stimulus to the formation of secondary metabolites, which are produced as a plant defense mechanism (ALARCÓN-FLORES et al, 2015;KLUGE et al, 2006), and may increase the functional food value. In addition, the biosynthesis of phenolic compounds may continue after harvest and increase during storage at low temperatures (CONCELLÓN et al, 2007;HOLCROFT et al, 1998) and modified atmosphere (SELCUK; ERKAN, 2015).…”

The study aimed to assess bioactive compounds and polyphenoloxidase activity of minimally processed eggplants stored in different atmospheres. Eggplants (Solanum melongena L.; cv. Ciça) were minimally processed (MP), sanitized and treated with a 2% citric acid solution. They were packed in plastic containers (vacuum) of nylon + transparent polyethylene and submitted to modified atmospheres with the following concentrations of gases: control (atmospheric air), vacuum, 4% O2 + 5% CO2,4% O2 + 6% CO2, 4% O2 + 7% CO2, and 4% O2 + 8% CO2, being stored in a cold chamber (5 ± 1 °C and 90 ± 1% relative humidity) for 10 days. The analyses consisted of the total phenolic compounds, total antioxidant activity, flavonoids, and polyphenoloxidase activity. The experimental design was a completely randomized design in a 6 × 6 factorial scheme (treatment vs. storage period). The data were submitted to analysis of variance and a regression analysis was performed for storage time. The active modified atmosphere with 8% CO2 is effective in reducing the polyphenoloxidase activity in minimally processed eggplant. The contents of phenolic compounds and flavonoids of minimally processed eggplant decrease with storage.

“…Their uses in indigenous medicine range from weight reduction to the treatment of many ailments including asthma, allergic rhinitis, nasal catarrh, skin infections, rheumatic diseases and swollen joint pains, gastroesophageal reflux, constipation, dyspepsia [3]. Several studies support the folkloric use of plants in local foods and medicinal preparations; For example, various investigators reported significant analgesic, antiinflammatory, anti-asthmatic, anti-glaucoma, hypoglycemic, hypolipidemic and weight loss effects of eggplants, particularly S. melongena, on test animals and animals human beings [4]. Pharmacological properties have been attributed to the presence of certain chemical substances in plants, such as fibers, ascorbic acid, phenols, anthocyanins, glycoalkaloids and α-chaconine [5,6].…”

Background: The use of plants for healing dates back to very remote times. Nowadays with the accession of new diseases plants are increasingly used for the formulation of new drugs able to overcome the many diseases (cancer, atherosclerosis) often caused by the disorder of the system prooxidant/antioxidant. Aim/Objective: On the strength of this observation, the research of an antioxidant plant is essential, hence the aim of this study, which is to determine the antioxidant activity of the stalk and the fruit of Solanum aethiopicum L. Methods: The fruits and stalk were washed, cut into fine slats, then dried in the incubator for three days and finally crushed into powder. An extraction by decoction with ethanol (stalks and fruits) and water (fruit) was subsequently carried out to obtain three extracts (ethanol and water). Antioxidant activity was evaluated through the FRAP method, and the trapping of radical DPPH. Results: For the FRAP method, at the highest concentration (1 mg/ml) the aqueous extract of the fruit (74.84±2.97%) has a higher reducing power compared to those of the ethanolic extracts of the fruit (70.15 ± 5.72%) and the stalk (49.85 ± 2.11%). These reducing powers, although significant, remain lower than those of tannic acid (89.95±0.007%). And finally, for the DPPH method, the aqueous extract of the fruit is more effective in reducing free radical DPPH with a IC50= 162±33 µg/ml, follow up by ethanol extract from the stalk (IC50= 360± 90 µg/ml) and finally ethanol extract from the fruit (IC50= 362.5± 23.5 µg/ml). These results confirm the in vitro antioxidant activity of the studied parts of Solanum aethiopicum. Conclusion: Prospective studies could focus on acute and subacute toxicities and the determination of the molecules responsible for the activity.

“…However, given the lack of comprehensive studies on the eggplant genome, only 775 pathogen recognition genes have been reported in the eggplant, compared to more than 1,000 genes in each of the three other Solanaceae crops (tomato, pepper, and potato) [22], which influences the progress of studies on the evolution of disease resistance in different Solanaceae plants [23]. Eggplants are the richest source of chlorogenic acid (CGA; 5- O -caffeoylquinic acid) [24, 25]. This dietary phenolic acid has been proven to exhibit anti-inflammatory, antimutagenic, and antiproliferative activities; however, the mechanism of CGA formation in the eggplant has not been well elucidated [26, 27].…”

SummaryThe eggplant (Solanum melongena L.) is one of the most important Solanaceae crops, ranking third in the total production and economic value in the genus Solanum. Here, we report a high-quality, chromosome-scale eggplant reference genome sequence of 1,155.8 Mb, with N50 of 93.9 Mb, which was assembled by combining PacBio long reads and Hi-C sequencing data. Repetitive sequences occupied 70.1% of the assembly length, and 35,018 high-confidence protein-coding genes were annotated based on multiple evidence. Comparative analysis revealed 646 species-specific families and 364 positive selection genes, conferring distinguishing traits to the eggplant. We performed genome-wide identification of disease resistance genes and discovered an expanded gene family of bacterial spot resistance in the eggplant and pepper but not in tomato and potato. The genes involved in chlorogenic acid synthesis were comprehensively characterized. Highly similar chromosomal distribution patterns of polyphenol oxidase genes were observed in the eggplant, tomato, and potato genomes. The eggplant reference genome sequence will not only facilitate evolutionary studies in the Solanaceae but also facilitate their breeding and improvement.
