“…Similar results were obtained by Shahat et al [ 144 ], who found that the B-type procyanidin trimer showed higher antioxidant activity compared to larger oligomers. Moreover, in studies carried out by Zhang et al [ 145 ] and Wojdyło et al [ 50 ] on Prunus padus and Prunus cerasus fruits, respectively, it was found that the antioxidant capacity was directly related to the proanthocyanidins present.…”

Prunus lusitanica L., also known as Portuguese laurel or locally known as ‘azereiro’, is a rare species with ornamental and ecological value. Only two studies regarding the bioactivity and chemical composition of its leaves were reported to date. Thus, the present study aims to qualitatively and quantitatively evaluate the phenolic profile, through HPLC-PAD-ESI-MS/MS (high-performance liquid chromatography–photodiode array detection–electrospray ionization tandem mass spectrometry), as well as the radical scavenging capacity, through ABTS (2,2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid) and DPPH (2,2-diphenyl-1 picrylhydrazyl), and the reducing power (FRAP, ferric reducing antioxidant power) assays, of P. lusitanica fruits during a 4-year study. In total, 28 compounds were identified and quantified in the fruits, including 21 hydroxycinnamic acids (60.3%); 2 flavan-3-ols (27.9%), 2 anthocyanins (10.5%), 2 flavonols (1.0%), and 1 secoiridoid (0.3%). High antioxidant capacity was observed, with ABTS values ranging from 7.88 to 10.69 mmol TE (Trolox equivalents)/100 g fw (fresh weight), DPPH values from 5.18 to 8.17 mmol TE/100 g fw, and FRAP values from 8.76 to 11.76 mmol TE/100 g fw. According to these results, it can be concluded that these are rich sources of phenolic compounds with very promising antioxidant capacity and, therefore, with potential applications in the food and/or phytopharmaceutical sectors.

“…The results of our correlation analysis confirmed the close connections between antioxidant capacity and metabolites. Numerous studies have indicated that TPC can enhance antioxidant capacity [1], thereby inhibiting the production of free radicals and activating the intracellular antioxidant defense system [6]. Additionally, coated treatments can create a microenvironment on the surface of blue honeysuckle, which can slow down the respiration rate and influence the physiological metabolism of postharvest blue honeysuckle.…”

“…Blue honeysuckle (Lonicera caerulea L.) fruit is hailed as a "homology of medicine and food" due to its rich reservoir of bioactive compounds and nutritional properties [1]. It has demonstrated a diverse range of biological activities, including anti-lung injury, anti-cancer, anti-obesity, anti-viral, anti-bacterial, anti-diabetic, and radiation resistance [2].…”

This study investigated the impact of chitosan (CH, 1%) and aloe vera gel (AL, 30%) edible coatings on the preservation of blue honeysuckle quality during a 28-day storage at −1 °C. Coating with CH, AL, and CH+AL led to notable enhancements in several key attributes. These included increased firmness, total soluble solids, acidity, pH, and antioxidant capacity (measured through DPPH, ABTS, and FRAP assays), as well as the preservation of primary (ascorbic acid) and secondary metabolites (TPC, TAC, and TFC). The TAC and TFC levels were approximately increased by 280% and 17%, respectively, in coated blue honeysuckle after 28 d compared to uncoated blue honeysuckle. These coatings also resulted in reduced weight loss, respiration rate, color, abscisic acid, ethylene production, and malondialdehyde content. Notably, the CH+AL treatment excelled in preserving secondary metabolites and elevating FRAP-reducing power, demonstrating a remarkable 1.43-fold increase compared to the control after 28 days. Overall, CH+AL exhibited superior effects compared to CH or AL treatment alone, offering a promising strategy for extending the shelf life and preserving the quality of blue honeysuckle during storage.

“…In order to find the structural features responsible for the activities, Alejo-Armijo A. et.al designed and synthesized six A-type procyanidins and evaluate their antimicrobial and antibiofilm properties against 12 resistant bacteria [ 15 ]. Zhang et al thoroughly investigate the structure, degree of polymerization, and starch hydrolase inhibition activities of bird cherry PAs, indicating that bird cherry oligomeric PAs are a promising starch hydrolase inhibitor for the application of potential functional food components [ 16 ]. Xu et al studied the effects of EGCG, EGC, and ECG on the chemical and cell-based antioxidant activity, sensory properties, and cytotoxicity of a catechin-free model beverage using response surface methodology [ 17 ].…”

To fully explore the influence mechanism of interactions between different monomer units of proanthocyanidins (PAs) on biological activity, a path analysis model of the PA structure-activity relationship was proposed. This model subdivides the total correlation between each monomer unit and activity into direct and indirect effects by taking into account not only each monomer unit but also the correlation with its related monomer units. In addition, this method can determine the action mode of each monomer unit affecting the activity by comparing the direct and total indirect effects. Finally, the advantage of this model is demonstrated through an influence mechanism analysis of Rhodiola crenulata PA monomer units on antioxidant and anti-diabetes activities.
