There is little study on melatonin’s ability to prevent salt damage in eggplants, despite the fact that it is a strong antioxidant in plants that has been found to help mitigate a variety of adverse challenges. In this study, we used “Anhui Eggplant No.8” as the test material and simulated salt stress by irrigating the roots with 150 mmol·L NaCl solution. Subsequently, we treated the eggplants with different concentrations of exogenous melatonin (0, 50, 100, 150, 200, 250 μmol·L) and assessed the plant traits and an array of physiological and biochemical indices following melatonin application to observe the impact of salt stress. Our study results indicate that exogenous melatonin at a concentration of 200 μmol·L can significantly alleviate the inhibition of eggplant photosynthesis under salt stress by increasing the content of chlorophyll in leaves and the activity of antioxidant enzymes. This leads to a notable increase in the levels of non-enzyme antioxidants and osmotic regulatory substances. As a result, the antioxidant capacity of the eggplants is enhanced, the degree of membrane lipid peroxidation is reduced, and the growth of eggplant seedlings under salt stress is effectively promoted, thereby strengthening the salt tolerance of eggplant seedlings. Fluorescence quantitative data analysis indicates thatSmCAT4is indeed a gene that positively regulates salt stress. However, in theSmPPOfamily, we did not find any genes that respond to salt stress. This research provides a theoretical foundation for improving the yield productivity and quality of eggplants under protected farming by clarifying the physiological mechanism by which melatonin controls the salt tolerance of eggplant seedlings.

Two novel cholestane-type steroidal saponins , melongoside R-S ( 1 - 2 ) and three novel furostanol-type steroidal saponins , melongoside T-V ( 3 - 5 ), together with three known steroidal saponins ( 6 - 8 ) were isolated from the seeds of Solanum melongna L. The structures of these compounds were elucidated by extensive spectroscopic analysis such as HR-ESI-MS, ESI-MS and NMR.

A novel NaOH modified eggplant straw biochar supported green nanoscale zerovalent iron (P-nZVI/ESBC) composite was synthesized and its removal performance and reaction mechanism for tetracycline (TC) in water were investigated. Multiple characterizations showed that the prepared P-nZVI/ESBC composite contained oxygen-containing functional groups (hydroxyl, carbonyl, and carboxyl groups) and Fe species (nZVI and its oxides). The dosage of composite, temperature, and solution pH significantly affected the removal capacity of the P-nZVI/ESBC composite for TC. The Avrami fraction-order kinetic model and Sips adsorption isotherm model can fit well the removal process of TC by the P-nZVI/ESBC composite, indicating that the adsorption behavior of TC involved multiple adsorption mechanisms and chemical adsorption might occur. The maximum adsorption capacity of the P-nZVI/ESBC composite for TC was 304.62 mg g−1. The adsorption and reductive degradation were the dominant mechanisms of TC removal by the P-nZVI/ESBC composite. This work offers abundant information on the application of eggplant straw to manufacture biochar-based composites for the efficient removal of antibiotic contaminants from aquatic environments.

Amitraz (AMT) is a broad-spectrum formamidine insecticide and acaricide. In this study, we produced an anti-AMT monoclonal antibody (mAb) with high performance. The half-maximal inhibitory concentration of the anti-AMT mAb was 4.418 ng/mL, the cross reactivity with other insecticides was negligible, and an affinity constant was 2.06 × 10 9 mmol/L. Additionally, we developed an immunochromatographic assay for the rapid detection of AMT residues in oranges, tomatoes, and eggplants. The cut-off values were 2000 μg/kg in oranges and tomato samples and 1000 μg/kg in eggplant samples and the calculated limits of detection were 14.521 μg/kg, 6.281 μg/kg, and 3.518 μg/kg in oranges, tomatoes, and eggplants, respectively, meeting the detection requirements for AMT in fruits and vegetables. The recovery rates ranged between 95.8 % and 105.2 %, consistent with the recovery rates obtained via LC-MS/MS. Our developed immunochromatographic assay can effectively, accurately, and rapidly determine AMT residues in oranges, tomatoes, and eggplants.

Adsorption techniques have been successfully applied in water purification for their simplicity, efficiency, and negligible byproducts. Porous carbon materials are effective dye adsorbents but have relatively low adsorption efficiency, slow adsorption rate, and high production cost, all of which need to be addressed for conducive practical applications. Herein, natural eggplant-based porous carbon materials (EPCMs) have been studied and successfully constructed to perform with high efficiency and fast rate of removal of dyes from wastewater. The hierarchical pore structure and well-developed mesoporous had a total pore volume of 0.6379 cm 3 /g and a maximum specific surface area of 516.0060 m 2 /g, which contributed to the high efficiency of adsorption (100%). The complete adsorption of Rhodamine B (basic and cationic dyes) solution within 25 min demonstrated its fast and high adsorption performance. The EPCMs also showed its efficiency in the absorption of various dyes, including methyl orange (acidic and anionic dye), methylene blue (basic and cationic dyes), and Yuan’qing B (reactive dye). Furthermore, the EPCMs were tested with actual wastewater from a production-based factory and recorded excellent removal effects as well, suggesting its prospective expansion for industrial applications. Therefore, this eggplant biomass-based porous carbon provides a promising approach for fast and highly efficient wastewater purification from dye-based contaminations.

A model food system was designed to explore the effects of food status and thermal treatment ways on degradation of crude anthocyanins from eggplant peel, formation of brown/polymeric color and changes of antioxidant capacity . The pathway of anthocyanin degradation was identified. Degradation of anthocyanins followed first-order kinetics and the rate constant value of anthocyanins were 0.24 and 0.38 h −1 for steamed cookies (solid-state) and boiled cookies (paste), respectively, which was lower than that of 0.71 and 0.39 h −1 for steamed liquid and boiled liquid, respectively. And the half-lives were 2.86, 1.79, 0.98 and 1.78 h steamed cookies, boiled cookies, steamed liquid and boiled liquid, respectively. The anthocyanin content was negatively correlated with the production of brown/polymeric color. The increase of brown/polymeric color index follows zero-order kinetics. The k values of brown index were 0.06, 0.10, 0.10 and 0.10 h −1 and the rate constants of polymeric color index were 0.04, 0.06, 0.05 and 0.07 h −1 for steamed and cookies, steamed and boiled liquid, respectively. The antioxidant activities decreased gradually with treatment time. In conclusion, steaming was a better way to retain anthocyanin than boiling for solid state food, while, boiling was preferable for liquid food.

The aim of this study was to develop intelligent/active packaging by using chitosan/esterified chitin nanofibers (CN) film matrix and anthocyanins from eggplant peel extract (EE) to monitor the freshness of pork. Fourier transform infrared spectroscopy , X-ray diffraction and zeta potential results showed that the CN filled into the film network and precisely bonded to the chitosan via electrostatic interactions and hydrogen bonding. Moreover, the incorporation of EE formed hydrogen bonds with chitosan and CN. Thermogravimetric analysis and scanning electron microscopy showed that the films became more compact and that thermal stability was improved. Hydrogen bonding, electrostatic interaction and nanofilling effects synergistically improved the mechanical and barrier properties (water vapor, oxygen and optical barrier properties) of the films with the addition of CN. When the content of CN was 5 wt%, the tensile strength, elongation at break, the water vapor and oxygen barrier properties of chitosan film were significantly increased by about 1.44, 1.52, 1.23 and 5.21 times (p < 0.05), respectively. When EE was added to the films, the antibacterial and antioxidant capacities of the film were significantly (p < 0.05) improved. All the films containing eggplant anthocyanins were sensitive to pH 3–11 buffer solutions, and the films had good ammonia-sensitivity and acid-sensitivity. Chitosan-CN-EE films effectively indicated the freshness of pork during storage. Hence, these results suggested that the chitosan-CN-EE films are promising candidates for intelligent and active food packaging applications.
