Liao M, Wang X. Ameliorating effect of Chinese jujube polyphenol on blood glucose oxidative stress in type 2 diabetic rats. J Diabetes Complications 2024; 38:108804. [PMID: 39096769 DOI: 10.1016/j.jdiacomp.2024.108804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 06/20/2024] [Accepted: 07/06/2024] [Indexed: 08/05/2024]
Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is a common metabolic disease characterized by insulin resistance and insufficient relative insulin secretion, leading to elevated blood sugar and the development of diabetic complications. T2DM not only seriously affects people's health and quality of life, but also brings a heavy burden to society and economy. At present, the treatment of T2DM mainly relies on drug therapy, but these drugs often have problems such as side effects, resistance and high cost, and can not fully meet the needs and expectations of patients. Therefore, it is of great significance and value to find safe and effective natural medicines or functional foods to assist the treatment and prevention of T2DM. OBJECTIVE Chinese jujube are a common fruit that contain abundant polyphenolic compounds, which exhibit multiple physiological activities, such as antioxidation, anti-inflammation, and blood glucose lowering. The objective of this study was to explore the impact of red date polyphenols on glycemic control and oxidative stress status in patients with type 2 diabetes mellitus (T2DM).

Ancuceanu R, Hovaneț MV, Miron A, Anghel AI, Dinu M. Phytochemistry, Biological, and Pharmacological Properties of Abies alba Mill. PLANTS (BASEL, SWITZERLAND) 2023; 12:2860. [PMID: 37571016 PMCID: PMC10421038 DOI: 10.3390/plants12152860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 07/24/2023] [Accepted: 08/01/2023] [Indexed: 08/13/2023]
Abstract
Abies alba Mill. (Pinaceae), silver fir, is a widespread gymnosperm species in Europe, important for its ecological, economic, social, and cultural significance, as well as for its use for food and bioremediation purposes. The various parts of the plant (leaves, branches, cones, wood, bark) are also of pharmaceutical interest due to their composition of active compounds. In the last three decades, an impressive amount of research has been dedicated to this species. The variability of the chemical composition of essential oils (whether they come from leaves, oleoresin from branches, or other parts of the plant) is impressive, even in the case of specimens collected from the same geographical area. For essential oils prepared from needles or twigs and branches, limonene, β-pinene, α-pinene, camphene, β-phellandrene, and bornyl acetate are the leading compounds, although their wide variations seem to correspond to multiple chemotypes. Both bark and wood are rich in lignans and phenolic compounds. Matairesinol is apparently the dominant lignan in bark, and secoisolariciresinol and lariciresinol are the dominant ones in wood samples. Pharmacological studies with promising results have evaluated the antioxidant effect (mainly due to essential oils), but also the antimicrobial, antitumor, probiotic, antidiabetic, anti-steatosis, and anti-psoriatic activities.

LC-DAD-ESI-MS/MS and NMR Analysis of Conifer Wood Specialized Metabolites. Cells 2022; 11:cells11203332. [PMID: 36291197 PMCID: PMC9600761 DOI: 10.3390/cells11203332] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 10/13/2022] [Accepted: 10/20/2022] [Indexed: 11/16/2022] Open
Abstract
Many species from the Pinaceae family have been recognized as a rich source of lignans, flavonoids, and other polyphenolics. The great common occurrence of conifers in Europe, as well as their use in the wood industry, makes both plant material and industrial waste material easily accessible and inexpensive. This is a promising prognosis for both discovery of new active compounds as well as for finding new applications for wood and its industry waste products. This study aimed to analyze and phytochemically profile 13 wood extracts of the Pinaceae family species, endemic or introduced in Polish flora, using the LC-DAD–ESI-MS/MS method and compare their respective metabolite profiles. Branch wood methanolic extracts were phytochemically profiled. Lignans, stilbenes, flavonoids, diterpenes, procyanidins, and other compounds were detected, with a considerable variety of chemical content among distinct species. Norway spruce (Picea abies (L.) H.Karst.) branch wood was the most abundant source of stilbenes, European larch (Larix decidua Mill.) mostly contained flavonoids, while silver fir (Abies alba Mill.) was rich in lignans. Furthermore, 10 lignans were isolated from the studied material. Our findings confirm that wood industry waste materials, such as conifer branches, can be a potent source of different phytochemicals, with the plant matrix being relatively simple, facilitating future isolation of target compounds.

Abstract
Silver fir (Abies alba Mill.) is one of the most common and valuable conifer tree species in Central Europe, with well-established usage in the construction and furniture industries, as well as the food, health products, pharmaceuticals and cosmetics industries. Silver fir branch extract, a mixture of antioxidative phenols, is produced industrially as a food supplement with a wide range of therapeutic properties. This study investigates optimization of the production of silver fir branch extract by researching its antioxidant activity (ABTS and DPPH assay), phenol content (Folin-Ciocalteu assay), lignan content (HPLC) and extractable content at various distances from the trunk (0–80 cm). The antioxidative activity, phenol content and extractable content decreased from the proximal to the distal part of the branch. The decrease in ABTS assay activity was 51%, and that of the DPPH assay was 52%; the decrease in total phenol content was 35–40%; and the decrease in lignan content was 91%. The extractable matter content was reduced by 40%. Data gained in the study herein justifies the importance of researching existing and industrially produced plant extracts for further optimization of the final product. Results shows that industry can also produce extracts with elevated content of lignans with the use of short proximal parts of the branches.

Abstract
The study of medicinal plants for cancer treatment has gained attention due to an increasing incidence of cancer worldwide and antineoplastics-related undesirable secondary effects. Most of the natural products of medicinal plants that have been evaluated for cytotoxic activity, are derived from leaves, bark, roots and flowers. However, natural products derived from wood have demonstrated a cytotoxic effect with promising results. Moreover, some fractions and compounds have been isolated of wood in order to increase the effect. This review presents in vitro experimental evidence of cytotoxic effect of natural products from wood against cancer cell lines. It also provides considerations and recommendations to obtain herbal medicines over time.

Abstract
Background: Oxidative stress is a key factor in the pathophysiology of many diseases. This study aimed to verify the antioxidant activity of selected plant phenolics in cell-based assays and determine their direct or indirect effects. Methods: The cellular antioxidant assay (CAA) assay was employed for direct scavenging assays. In the indirect approach, the influence of each test substance on the gene and protein expression and activity of selected antioxidant enzymes was observed. One assay also dealt with activation of the Nrf2-ARE pathway. The overall effect of each compound was measured using a glucose oxidative stress protection assay. Results: Among the test compounds, acteoside showed the highest direct scavenging activity and no effect on the expression of antioxidant enzymes. It increased only the activity of catalase. Diplacone was less active in direct antioxidant assays but positively affected enzyme expression and catalase activity. Morusin showed no antioxidant activity in the CAA assay. Similarly, pomiferin had only mild antioxidant activity and proved rather cytotoxic. Conclusions: Of the four selected phenolics, only acteoside and diplacone demonstrated antioxidant effects in cell-based assays.

Revealing the mechanisms and the material basis of Rubia cordifolia L. on abnormal uterine bleeding with uniting simultaneous determination of four components and systematic pharmacology approach-experimental validation. J Pharm Biomed Anal 2020; 189:113475.

Abstract
The roots of Rubia cordifolia L. (RCL) have become an important medicine for abnormal uterine bleeding (AUB) and hemorrhage syndrome in Traditional Asian medicine. However, the underlying mechanism and the material basis of RCL for treating AUB has not been fully elucidated. In this study, quantitative evaluation of quinones, systematic pharmacology and experimental verification were adopted. Firstly, the Disease-Ingredient-Target network was established by Cytoscape, which was consistent with 23 compounds and 47 target genes. The hub targets were discovered by Maximal Clique Centrality (MCC) method with Cytohubba plugins of Cytoscape, and top 20 nodes were ranked by MCC. It was assumed that mollugin is the main ingredient of RCL for treating AUB. Pathways on which RCL acted were obtained from observation of its biological functions, KEGG pathways and Reactome pathway enrichment analysis. The possible mechanism of RCL for treating AUB was revealed for improvment of the blood clotting system, blood circulation, arachidonic acid metabolism and inflammation. Then, a novel method for evaluating the quality of RCL was established, and the content of mollugin in RCL was the higher than others. Finally, pharmacologic experiments confirmed that RCL could improve the inflammation by inhibiting the activity of COX-2 and cPLA2 enzyme, ameliorate blood hypercoagulability by affecting coagulation cascade and fibrinolytic system. It was found that RCL inhibited the expression COX-2 and PAI-1 by reducing HIF-1α expression. The trend of each index of mollugin was consistent with that of RCL, indicating that it played an important role in RCL for treating AUB. The above results could provide a novel method for the quality evaluation of RCL and was expected to give us more important information regarding the use of RCL as a promising drug candidate for AUB, offering a fertility preserving medical, non-hormonal treatment choose for women with AUB.

Abstract
Polyphenols are the general designation of various kinds of phytochemicals, mainly classified as flavonoids and nonflavonoids. Polyphenolic compounds have been confirmed to exhibit numerous bioactivities and potential health benefits both in vivo and in vitro. Dietary polyphenols have been shown to significantly alleviate several manifestations of metabolic syndrome, namely, central obesity, hypertension, dyslipidemia, and high blood sugar. This review is aimed at discussing the bioprotective effects and related molecular mechanisms of polyphenols, mainly by increasing antioxidant capacity or oxygen scavenging capacity. Polyphenols can exert their antioxidative activity by balancing the organic oxidoreductase enzyme system, regulating antioxidant responsive signaling pathways, and restoring mitochondrial function. These data are helpful for providing new insights into the potential biological effects of polyphenolic compounds and the development of future antioxidant therapeutics.

Abstract
Extracts from parts of coniferous trees have received increased interest due to their valuable bioactive compounds and properties, useful for plenty of experimental and consolidated applications, in fields comprising nutraceutics, cosmetics, pharmacology, food preservation, and stimulation of plant growth. However, the variability of the bioactive properties, the complexity of the extraction methods, and the use of potentially harmful synthetic chemicals, still represent an obstacle to the spreading of such valuable natural compounds. Hydrodynamic cavitation is emerging as a promising innovative technique for the extraction of precious food components and by-products from waste raw material of the agro-food production chain, which can improve processing efficiency, reduce resource consumption, and produce healthy, high-quality products. In this study, a process based on controlled hydrodynamic cavitation was applied for the first time to the production of aqueous solutions of silver fir (Abies alba Mill.) needles with enhanced antioxidant activity. The observed levels of the in vitro antioxidant activity, comparable or higher than those found for reference substances, pure extracts, and other water extracts and beverages, highlight the very good potential of the hydrodynamic cavitation (HC) process for the creation of solvent-free, aqueous solutions endowed with bioactive compounds extracted from silver fir needles.
