“…19,20 Ultrasound-assisted solid-liquid extraction (UA-SLE) of phenolic compounds combined with RSM has been reported as an effective tool for the extraction and analysis of plant bioactive compounds. 21 In the present study, RSM was used to optimize the UA-SLE of total phenolic compounds (TPC) from leaves of C. macrophyllum by employing BBD to determine solvent and concentration effects on extraction efficiency, sonication time, liquid-solid ratio (LS ratio), and ultrasound power. We also evaluated the combined effects of these operating variables.…”

This study determines the optimal conditions for the ultrasound-assisted solidliquid extraction (UA-SLE) of the total phenolic compounds (TPC) of Cenostigma macrophyllum leaves. The experiments were carried out according to three-level, four-variable Box-Behnken design combined with the response surface methodology (RSM). Extraction (sonication) time, liquid-solid ratio, methanol concentration, and ultrasonic power were investigated as independent variables to obtain the optimal extraction conditions for TPC. Data were fitted to a second-order polynomial model, and the model fitness was evaluated by the analysis of variance, which indicated the model (P < 0.0001), presenting precision and reliability with the experiments performed (R 2 = 0.9947, coefficient of variance [CV] = 4.29, SD = 1.67). Individual and interactive effects of the independent variables on TPC extraction were interpreted using the proposed mathematical model. The results showed that for the maximum TPC extraction, the optimal conditions included 32 min extraction time, 29.73 mLÁg −1 liquid-solid ratio, 47.72% methanol concentration, and 145.71 W ultrasonic power. Under these optimal conditions, the predicted values were in agreement with the experimental values, thus validating the RSM model. When the optimal conditions were compared with those of conventional extraction techniques, the results showed that UA-SLE presented significantly better results for TPC extraction (71.2% to 138.3% more efficient) and for antioxidant activity (115.0% to 179.2% more efficient). High-performance liquid chromatography analysis of the extracts revealed that UA-SLE did not interfere with the extract chemical composition, thus confirming that it was more effective than conventional techniques.

“…Several natural organic boron (NOB) species have been detected in bacteria (borate polyketides, borate-siderophore complexes, AI-2B), fungi (borate esters of carbohydrates), and plants (rhamnogalacturonan II-borate complex (BPP), borate esters of carbohydrates, borate esters of organic acids, bis-N-acetyl serine, and borate complexes of phenolic acids, such as DCB) [112,113,124,125]. From digestibility assays of NOBs, only the prebiotic properties of BPP [126,127] and DCB complexes extracted from green coffee beans (GCB) [112] were highlighted. These organic B species are distinct from inorganic BA/borates, which aren't prebiotic because they are digestible and could be toxic to the microbiota [124,128].…”

The microbiota–gut–brain axis has garnered increasing attention in recent years for its role in various health conditions, including neuroinflammatory disorders like complex regional pain syndrome (CRPS). CRPS is a debilitating condition characterized by chronic neuropathic pain, and its etiology and pathophysiology remain elusive. Emerging research suggests that alterations in the gut microbiota composition and function could play a significant role in CRPS development and progression. Our paper explores the implications of microbiota in CRPS and the potential therapeutic role of boron (B). Studies have demonstrated that individuals with CRPS often exhibit dysbiosis, with imbalances in beneficial and pathogenic gut bacteria. Dysbiosis can lead to increased gut permeability and systemic inflammation, contributing to the chronic pain experienced in CRPS. B, an essential trace element, has shown promise in modulating the gut microbiome positively and exerting anti-inflammatory effects. Recent preclinical and clinical studies suggest that B supplementation may alleviate neuropathic pain and improve CRPS symptoms by restoring microbiota balance and reducing inflammation. Our review highlights the complex interplay between microbiota, inflammation, and neuropathic pain in CRPS and underscores the potential of B as a novel therapeutic approach to target the microbiota–gut–brain axis, offering hope for improved management of this challenging condition.

“…The mass distribution of water-soluble vs. structural B retrieved from one sample was correlated with that of the mass of total B measured by the dry ash method. These two types of B-containing moieties yielded the following the following B concentrations: 14.1 ± 2.8 mg/kg to 90.9 ± 2.5 mg/kg, as water-soluble B, and 27.2 ± 3.2 mg/kg to 67.1 ± 1.7 mg/kg, as structural (water-insoluble) B, respectively [ 39 ]. B has been shown to be complexed to fructose borate esters (FBEs) and also to glucose borate esters (GBEs) in the extracellular nectar from peach [ 14 , 15 ].…”

Sugar–borates (SBs) are mono- or di-sugar–borate esters (SBEs) comprised of one or two monosaccharide molecules linked to a boron (B) atom. SBEs occur naturally in commonly consumed herbs, vegetables, fruits, seeds, and nuts and, other than greatly varying levels of B found in local drinking water, are the primary natural dietary sources of B-containing molecules in humans. To date, the most studied SBE is calcium fructoborate (CaFB). CaFB represents an important example of how organic B-containing molecules are significantly distinct from their inorganic counterparts. During these past two decades, CaFB has been researched for its physical and biochemical characteristics, safety, and clinical outcomes. Results of these researches are presented and discussed herein. CaFB has been characterized using Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), high-performance thin-layer chromatography (HPTLC), nuclear magnetic resonance (NMR), liquid chromatography–multistage accurate mass spectrometry (LC-MSn), X-ray diffraction (XRD), Raman spectroscopy, and inductively coupled plasma (ICP) in non-biological and biological specimens. Potential health benefits of CaFB have been clinically investigated in pilot and efficacy studies demonstrating (i) significant reductions in knee discomfort and improved flexibility within 7, 14, and 90 days and (ii) significant effect on blood levels of inflammatory, cardiovascular, and other biomarkers. These studies support the use of CaFB as a dietary supplement for the management of joint discomfort. CaFB is presented here in order to illustrate how physiological benefits are imparted by distinct organic boron-containing molecules rather than solely by the element B itself. Considering recent National Health and Nutrition Examination Survey (NHANES) data reporting increases in age-related joint pain and an increasing elderly demographic, SBEs offer potential for safe, natural, and effective management of joint discomfort and improved mobility in human and animal health applications. Several of these studies may also open new opportunities for use of SBEs for health benefits beyond joint health.
