Special Issue Information

Dear Colleagues,

The plant kingdom is a source of essential nutrients and also provides constituents with biological activity for human and animal bodies. A wide variety of compounds and complexes participate in processes that maintain the integrity of the vegetal organism, and can have functions in human and animal organisms in equal measure. The aim of the Special Issue "Bioactive Compounds in Horticultural Plants—2nd Edition" is to present a comprehensive analysis of plants as bioactive compounds sources, to identify the vegetal organs in which they are found at the highest level and the timing of their maximum availability. It will highlight the structural and functional diversity of biologically active compounds, the established synergistic or antagonistic relationships, and how the isolation of some components could affect their activity.

Another concern is the role that bioactive compounds play in the body as antioxidants, protectors of the structural, functional, and energetic components; adjuvants of physiological processes; their antiviral and antimicrobial properties, as well as the role of an activator/suppressor of enzymatic systems or genes.

Studies on non-beneficial actions (antinutrient activity or interaction with drugs), the pro-oxidant role they may play in certain circumstances, and alterations in the activity of the biomolecule as a result of treatments during extraction or processing protocols are also of interest.

Bioactive compounds remain among the most studied plant components, and understanding the relationships between them and those related to the reaction environment can clarify problems related to their activity, the success of isolation and quantification, and the study of biological activity both in vitro and in vivo.

This Special Issue aims to highlight the perspectives of an unlimited research field that offers solutions or models for the optimal achievement of the benefits possessed by the plant kingdom.

Crataegus monogyna (CM) fruits are highly regarded for their rich nutritional content, boasting elevated levels of various beneficial secondary metabolites like total polyphenols, including anthocyanins, and ample amounts of ascorbic acid and antioxidant activity. Despite the acknowledged benefits of CM fruits, researchers have directed more attention toward its leaves and flowers. Consequently, the current research attempts to optimize extraction techniques for CM fruit using a multifaceted approach involving varied durations, temperatures, and concentrations of ethanol solvent to isolate the diverse range of bioactive components present effectively. High-performance liquid chromatography coupled with a diode array detector (HPLC-DAD) is employed for the identification and quantification of polyphenolic compounds. According to the results, by following the optimum extraction parameters (50% ethanolic solvent, 50 °C extraction temperature, and 60 min extraction time), the total polyphenol content can be increased up to 410%, reaching 55.59 mg gallic acid equivalents/g. Using 50% ethanolic solvent, 80 °C extraction temperature, and extraction time of 90 min, the total anthocyanin content can be enhanced by more than 560%, reaching a quantity of 51.83 μg cyanidin equivalents/g. Moreover, the antioxidant activity of CM fruit extracts can reach 415.95 μmol ascorbic acid equivalents (AAE)/g dw (by FRAP method), using 50% ethanolic solvent, 50 °C extraction temperature, and 60 min extraction time, and 270.26 μmol AAE/g dw (by DPPH method) and 1053.28 mg/100 g dw ascorbic acid content, using 50% ethanolic solvent, 80 °C extraction temperature, and 90 min extraction time. This comprehensive study seeks to augment the already substantial content of bioactive compounds found in CM, resulting in an extract with promising applications across the pharmaceutical, food, and cosmetics industries.

Diplocarpon rosae Wolf is the most common and damaging fungal pathogen in roses. Nationwide, the attack of this pathogenic fungus is very serious in most rose gardens due to rapid disease development that typically leads to leaf yellowing and defoliation. This study aimed to assess the way in which the fungus’s attack affects the chemical composition of Rosa sp. leaves. The research was conducted in the summer of 2023 on ten cultivars of rose grown in the rosary in the ‘Alexandru Buia’ Botanical Garden in Craiova. The influence of the cultivar and harvest time was discussed. Leaf black spot on roses produced by the fungus Diplocarpon rosae Wolf affected plants in all cultivars and the differences between cultivars highlighted the sensitivity of the relationship between plants and pathogens when exposed to some microclimatic environment factors. The correlations of attack degree with tannins, chlorophyll, or alkaloids were significant, negative for tannins (r = −0.189 *) and chlorophyll (r = −0.517 ***) and positive for alkaloids (r = 0.510 ***). Between phenolic compounds, tannins, flavonoids, and chlorophyll, very significant positive correlations were found. Alkaloids established negative and also very significant correlations with phenolic compounds (r = −0.403 ***), tannins (r = −0.339 ***), flavonoids (r = −0.409 ***), and chlorophyll (r = −0.604 ***).
