Objective: To perform the phytochemical analysis of extracted walnut oil (EWO) and its subchronic toxicity profile in Sprague Dawley rats. Methods: In this experimental study, the collected Kurdish walnut was authenticated by an authorized taxonomist and the core was obtained. Then, the walnut oil was extracted using the cold press method and sent for phytochemical analysis using GC-MS. Accordingly, the male Sprague Dawley rats were treated with varying doses of the EWO for four consecutive weeks, and animals were checked daily for abnormality and toxicity behaviours while they were weighed each week. At the end of the study, animals were sacrificed under deep anaesthesia, blood samples and organs were collected, and various hematological and biochemical tests were performed together with histopathological analysis. Results: GC-MS analysis showed that EWO contained 49 compounds, some critical in biomedical fields. The body weight of all treated animals was increased significantly. No significant changes were seen for hematological tests except platelets, which decreased in all treated groups (p = 0.015) compared to the control group. At the same time, AST and chloride levels were decreased (p = 0.002 and p = 0.012, respectively), while total protein and calcium were increased (p = 0.004 and p = 0.033, respectively). Simultaneously, histopathological analysis showed no severe lesions in the brain, moderate lesions in the liver and mild, moderate and severe lesions in the kidneys. Conclusions: EWO is rich in various compounds that contain active medicinal components. The EWO can be used at low doses as it does not affect most hematological and biochemical tests and has no significant toxicity in the vital organs of experimental rats.","PeriodicalId":19019,"journal":{"name":"Natural Product Communications","volume":"11 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ST is commonly called Brazil pepper and aroeira. Several reports have been made on the biological activities of ST, but studies on leaf extracts, especially lectins, have mainly been reported. Objectives: Our study analyzed the active compounds, antioxidant activities, xanthine oxidase inhibitory, elastase inhibitory, and tyrosinase inhibitory activities of S. terebinthifolia (ST) bark extract. Results: Hot water extracts showed the strongest electron donating ability (84.46%) and tyrosinase inhibitory activity (67.1%). Eighty percent ethanol extract showed the highest reducing power, total phenolic, xanthine oxidase (91.7%) and elastase inhibitory ability (85.44%). Catechin, α–amyrin, β–amyrone and 11-Oxo-.α-amyrin were identified through HPLC and GCMS analysis, while eighty percent extract contained the highest amount of catechin. Catechin, α–amyrin, and β–amyrone are considered to be the main xanthine oxidase inhibitors, while β–amyrone is considered to be the main inhibitor of xanthine oxidase and elastase. Conclusion: Through this study, we reported the basic information that S. terebinthifolia bark extract was used in folk medicine as an anti-inflammatory, anti-gout, and skin disease improvement material. S. terebinthifolia bark extract could be used as an anti-gout natural drug or cosmetic material.","PeriodicalId":19019,"journal":{"name":"Natural Product Communications","volume":"49 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some years ago, we described, using theoretical calculations, that a 4-hydroxy-1,2-quinone is more than 11 kcal/mol less stable than a 3-hydroxy-1,4-quinone making coexistence in nature of this type of quinones. In the present study, we approach the situation by comparing of the experimental <jats:sup>13</jats:sup>C-NMR data for 1 and those described for 2 with the calculated using computational methods.

It is susceptible to oxidation and deterioration. The aim of this study was to improve the stability of ZSSO and protect its quality. Methods: gelatin-sodium alginate was used as the wall material for the preparation of ZSSO microcapsules by the complex coacervation. The particle size and zeta potential of the microcapsules were determined using a Malvern particle size meter. The microstructure and stability of the microcapsules were determined by SEM, FTIR, TGA and PV. The sleep-improving activity of the microcapsules was also determined by sleep induction assay, Elisa and HE staining. Results: The encapsulation efficiency of microcapsules was 56.08% ± 0.19%, average particle size was 166.17 nm, and zeta potential was 38.2. Morphology of microcapsules was observed by SEM. The FTIR results showed that the fatty oil was successfully embedded, and PV indicated that microcapsules had a slow oxidation rate. A preliminary study on the sleep-improving activity of ZSSO and microcapsules demonstrated that it could shorten sleep latency and prolong sleep time of insomniac mice, and increase the levels of 5-HT and GABA and decrease the level of Glu in the brain of mice. In addition, ZSSO and microcapsules can repair damaged neuronal cells in the hypothalamus of insomniac mice to improve sleep. Conclusion: The quality evaluation of the microcapsules indicates that the prepared ZSSO-MPs have a small particle size and good stability.

The targets of blood-entering components were predicted by SwissTargetPrediction. Targets related to CHD were collected using multiple databases. The GO and KEGG enrichment analyses were used to predict the mechanisms of HJT therapeutic CHD, and PPI and “Components-Targets-Pathways” network were used to identify and elucidate the core targets. The key blood-entering components aimed at the core target are screened by molecular docking and QSAR analysis.ResultsA total of 14 blood-entering components were detected in serum samples of rat after administration, and the 32 potential targets of HJT therapeutic CHD were screened out. The result of PPI network showed that the core targets of HJT for the treatment of CHD include MMP1, GSK3B, EGFR and PTGS2, and the 5 key components with high degree were screened out. The GO and KEGG enrichment analyses indicate that HJT therapy for CHD is associated with the IL-17 and cGMP-PKG signaling pathways. The result of molecular docking indicate that the binding energy of coroglaucigenin to PTGS2 is the largest and it may be the key pharmacological component of HJT, and the QSAR analysis showed that Boldine and Coroglaucigenin had excellent activity in inhibiting PTGS2.ConclusionsIn this study, the blood-entering components of HJT were preliminarily identified, Combined network pharmacology and molecular docking analyses revealed that the PTGS2 may be a core target, and the IL-17 and cGMP-PKG signaling pathways may be the key pathways.

However, no systematic study has been conducted to evaluate its efficacy. Therefore, the present study focused on evaluating the potential health benefits, including the chemical constituents of the distillate. This distillate was prepared and identified as Siddhalepa Asamodagam Spirit (Sid.AS).MethodsThe chemical constituents of Sid.AS were identified and quantified using Gas Chromatography-Mass Spectrometry (GC-MS) method. The antioxidant potential of Sid.AS samples was assessed in vitro using DPPH and ABTS assays. Various concentrations of Sid.AS were subjected to antimicrobial, anti-obesity, anti-diabetic, anti-inflammatory, and urease inhibition assays according to the standard methods specified by the Ayurvedic Department in Sri Lanka.ResultsThymol was identified as the major compound in Sid.AS through GC-MS analysis. Sid.AS demonstrated significant anti-urease, anti-inflammatory, anti-lipase, and antioxidant activities, as evidenced by low IC<jats:sub>50</jats:sub> values compared to the positive controls. This suggests its potential in controlling gastric-related disorders, scavenging free radicals, and managing obesity by inhibiting the breakdown and absorption of fats. Additionally, Sid.AS exhibited inhibitory effects against alpha-amylase and alpha-glucosidase enzymes, indicating potential anti-diabetic activity by regulating blood sugar levels. Sid.AS displayed strong antimicrobial activity against tested microorganisms, with higher zones of inhibition and lower MIC and MLC values, indicating its effectiveness in combating microbial infections. Findings from the anti-lipase assay demonstrated activity comparable to that of the positive control, Orlistat.ConclusionThe findings of Sid.AS suggest its potential as a multi-functional bioactive herbal distillate with various pharmacological activities. Our results highlight that Sid.AS is a promising natural herbal extract with diverse pharmacological properties, including anti-urease, antioxidant, anti-inflammatory, anti-diabetic, anti-obesity, and antimicrobial activities.
