Abstract
In this study, a practicably complementary size exclusion chromatography and reversed-phase liquid chromatography method was constructed and applied to efficiently separate and purify structural analogs or isomers from natural products. First, a ternary styrene-divinylbenzene matrix CHP20P medium-pressure elution system was applied for Ligustrum qianluoenenst leaf crude sample pretreatment, with a recovery of 91.2 %, and 13.0 g of the target fraction Fr4 was obtained. A complementary HW-40C SEC and ReproSil-Pur C18 AQ RPLC system was subsequently constructed by optimizing the HW-40C separation conditions and ReproSil-Pur C18 AQ analysis. Finally, the established complementary SEC and RPLC method was used for the separation and purification of compounds from Ligustrum qianluoenenst leaf target fraction Fr4, and 12 flavone-C-glycosides were successfully prepared with purities exceeding 95 %. The overall methodologies established for flavone-C-glycoside preparative isolation have the potential to maximize the possibility of discovering more structural analogs, including new structural analogs or isomers from natural products.

Abstract
Assessing the total antioxidant capacity (TAC) in biological samples, such as saliva, is essential for health monitoring and disease prevention. TAC plays a critical role in protecting cells from damage caused by free radicals and oxidative stress, which are associated with various conditions, including cancer, cardiovascular diseases, and aging. Key antioxidants, including ascorbic acid (AA), cysteine (CYS), glutathione (GSH), and uric acid (UA), significantly contribute to this protective effect, with salivary levels of these antioxidants reflecting their concentrations in the bloodstream. Therefore, there is a strong demand for a robust, non-toxic colorimetric sensor that can effectively monitor these antioxidants using an innovative approach. This study introduces a multi-colorimetric probe capable of generating high-resolution, naked-eye-detectable color readouts for evaluating salivary TAC. The probe utilizes the morphology-dependent properties of plasmonic nanostructures as recently developed colorimetric sensors, enabling precise and efficient analysis of salivary antioxidants. The assessment of antioxidants was conducted using the probe in combination with pattern recognition analysis for accurate identification and regression analysis for quantification. The probe exhibited linear responses to pure antioxidants and TAC over a broad concentration range: 3.1-60.0, 2.6-60.0, 1.2-20.0, 0.8-20.0, and 0.7-14.0 μmol L-1, with detection limits of 1.1, 0.9, 0.4, 0.3, and 0.2 μmol L-1 for AA, CYS, GSH, UA, and TAC-mixture, respectively. Moreover, performance metrics highlight the robustness and efficacy of the probe in detecting and quantifying antioxidant levels in saliva samples. The efficacy of the developed multi-colorimetric probe was rigorously validated through the analysis of real saliva samples for on-site TAC monitoring. This rapid, cost-effective, user-friendly, non-toxic, and non-invasive method allows for a comprehensive analysis of both individual and total antioxidants, making it highly applicable for health monitoring and disease prevention. Additionally, the probe generates unique response profiles based on varying ratios of endogenous antioxidants, enabling precise TAC quantification in saliva-an essential factor for clinical diagnostics.

Xi H, Weng Y, Zheng Y, Wu L, Han D. Diacetoxy-6-gingerdiol protects the extracellular matrix of nucleus pulposus cells and ameliorates intervertebral disc degeneration by inhibiting the IL-1β-mediated NLRP3 pathway. Heliyon 2024; 10:e37877. [PMID: 39568855 PMCID: PMC11577133 DOI: 10.1016/j.heliyon.2024.e37877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2024] [Accepted: 09/11/2024] [Indexed: 11/22/2024] Open
Abstract
Intervertebral disc degeneration (IDD) is a common cause of low back pain, causing a huge emotional and economic burden on patients and society. Reduction of nucleus pulposus cells (NPC) and extracellular matrix (ECM) is the main feature of IDD, and NPC is the main source of ECM. Thermal apoptosis is a newly discovered form of cell death in recent years that differs significantly from apoptosis in terms of molecular mechanisms and cellular morphological changes. Diacetoxy-6-gingerdiol(D-6-G), a type of gingerol, has anti-inflammatory and antioxidant effects, but whether it has an inhibitory effect on cellular pyroptosis is not clear. Therefore, in the present study, we investigated the effect of D-6-G on the ECM of the nucleus pulposus oblongata under IL-1β treatment, as well as the mechanism of its effect on NLRP3 inflammasome and cellular focal death. In vitro cellular experiments demonstrated that D-6-G could bind to and inhibit the activity of NLRP3 inflammasome, and interestingly, D-6-G could also inhibit cellular pyroptosis and protect the nucleus pulposusry cellular microenvironment by activating the Nrf2/HO-1 axis. In conclusion, we found that D-6-G could inhibit NLRP3 inflammatory vesicle activity as well as cellular pyroptosis in NPCs and protect the ECM, suggesting the potential of D-6-G to delay IDD.

Abstract
In this investigation, we successfully isolated and purified natural diarylheptanoids using an orthogonal offline two-dimensional RPLC × SFC approach, employing only the phenyl/tetrazole stationary phase. First, a styrene-divinylbenzene matrix medium pretreatment liquid chromatography system effectively processed chlorophyll-containing plant extract solution with a recovery rate of 33.8 %, obviating the need for concentration steps. Subsequently, an offline two-dimensional RPLC × SFC employing only the phenyl/tetrazole stationary phase achieved a remarkable 96.38 % orthogonality and was established and utilized in the preparative separation and purification of natural products. Finally, the constructed single stationary phase highly orthogonal RPLC × SFC system was successfully applied in the preparative separation and purification of natural diarylheptanoids from the Saxifraga tangutica target fraction and yielded four diarylheptanoids with purities exceeding 95 %.

Abstract
Natural glycosides widely distributed in medicinal plants are valuable sources of therapeutic agents, showing various pharmacological effects. The separation and purification of natural glycosides are meaningful for their pharmacological research, which face with great challenges due to the complex of medicinal plants samples. In this work, two kinds of functional monolithic separation mediums A and S were fabricated and fully applied in the online extraction, separation and purification of active glycoside components from medicinal plants with a simple-procedure closed-loop mode. Chrysophanol glucoside and physcion glucoside were detected and separated from Rhei Radix et Rhizoma using separation medium A as a solid-phase extraction adsorbent. Rhapontin was isolated and purified from Rheum hotaoense C. Y. Cheng et Kao using separation medium S as the stationary phase of high-performance liquid chromatography. Compared to the reported literatures, high yield of 5.68, 1.20 and 4.76 mg g-1 of these three products were obtained with high purity. These two online closed-loop mode methods were carried out using high-performance liquid chromatography system, in which the sample injection, isolation and purification procedures are all online mode, and reduced loss compared to offline extraction and purification procedures, thus achieving high recovery and high purity.

Abstract
In this review, we summarize the most used natural products as useful adjuvants in BC by clarifying how these products may play a critical role in the prevention, treatment and progression of this disease. BC is the leading cancer, in terms of incidence, that affects women. The epidemiology and pathophysiology of BC were widely reported. Inflammation and cancer are known to influence each other in several tumors. In the case of BC, the inflammatory component precedes the development of the neoplasm through a slowly increasing and prolonged inflammation that also favors its growth. BC therapy involves a multidisciplinary approach comprising surgery, radiotherapy and chemotherapy. There are numerous observations that showed that the effects of some natural substances, which, in integration with the classic protocols, can be used not only for prevention or integration in order to prevent recurrences and induce a state of chemoquiescence but also as chemo- and radiosensitizers during classic therapy.

Abstract
Natural products have been used extensively around the world for many years as therapeutic, prophylactic, and health-promotive agents. Ribes himalense Royle ex Decne, a plant used in traditional Tibetan medicine, has been demonstrated to have significant antioxidant and anti-inflammatory properties. However, the material basis of its medicinal effects has not been sufficiently explored. In this study, we established an integrated strategy by online HPLC-1,1-diphenyl-2-picrylhydrazyl, medium-pressure liquid chromatography, and HPLC to achieve online detection and separation of antioxidants in Ribes himalense extracts. Finally, four antioxidants with quercetin as the parent nucleus were obtained, namely, Quercetin-3-O-β-D-glucopyranoside-7-O-α-L-rhamnopyranoside, Quercetin-3-O-β-D-xylopyranosyl(1-2)-β-D-glucopyranoside, Quercetin-3-O-β-D-glucopyranoside, and Quercetin-3-O-β-D-galactoside. Until now, the four antioxidants in Ribes himalense have not been reported in other literatures. Meanwhile, the free-radical-scavenging ability of them was evaluated by DPPH assay, and potential antioxidant target proteins were explored using molecular docking. In conclusion, this research provides insights into the active compounds in Ribes himalense which will facilitate the advancement of deeper studies on it. Moreover, such an integrated chromatographic strategy could be a strong driver for more efficient and scientific use of other natural products in the food and pharmaceutical industries.

Abstract
Dracocephalum heterophyllum has been reported as a traditional Tibetan medicine with diverse therapeutic benefits for the effective treatment of various diseases. However, only a few reports on its free radical inhibitors are limited due to its complex chemical composition and difficult isolation and purification processes. In this study, five free radical inhibitors are isolated by an integrated chromatographic method from Dracocephalum heterophyllum, followed by an investigation of the in vitro antioxidant activity utilizing 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Medium-pressure liquid chromatography was used for the pretreatment of the crude extract of Dracocephalum heterophyllum and targeted separation and purification of the free radical inhibitors using high-pressure liquid chromatography; the antioxidant peaks are recognized by the separation and purification process in combination with an online HPLC-DPPH system. Five free radical inhibitors with purity higher than 95% were obtained, namely xanthotoxol, 5-hydroxy-8-methoxypsoralen, luteolin, methyl rosmarinate, and ethyl rosmarinate. Finally, DPPH assays are performed, and their IC50 values for isolated compounds are 250.39 ± 13.32 μM, 26.91 ± 1.93 μM, 66.87 ± 14.33 μM, 21.99 ± 3.17 μM, and 36.96 ± 1.72 μM, respectively. This method is effective in isolating free radical inhibitors from Dracocephalum heterophyllum, and it has the potential to be adopted for the isolation of antioxidants from other plants of medicinal value as well.
