Metabolite profiling and biochemical investigation of the antidiabetic potential of Loranthus pulverulentus Wall n-butanol fraction in diabetic animal models. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116963. [PMID: 37495027 DOI: 10.1016/j.jep.2023.116963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/15/2023] [Accepted: 07/23/2023] [Indexed: 07/28/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Globally, 537 million individuals are estimated to have diabetes. The traditional use of herbs for ameliorating diabetes symptoms is a common practice in Pakistan and use of Loranthus pulverulentus Wall (L. pulverulentus) by local people in Azad Jammu and Kashmir has been reported. AIM OF THE STUDY In the present study, the antidiabetic potential of standardized n-butanol fraction of leaves of L. pulverulentus Wall, which is a parasite of Dalbergia sisso Roxb was assessed in both alloxan (ALX) and streptozotocin (STZ) diabetic animal models. MATERIALS AND METHODS Chemical characterization of BF was performed using HPLC, GCMS and UHPLC-MS. The effect of the fraction (250 mg/kg) on insulin, plasma free fatty acids, L-lactate, pyruvate, MDA, HbA1c and glycogen levels in ALX and STZ animal models was determined. Liver and renal profiles were analyzed in the STZ model. Toxicological studies were performed by hemolytic, Ames mutagenicity, DNA protection, and thrombolytic assays. Histopathological analysis of the pancreas, liver, and kidney was performed. RESULTS BF demonstrated highly significant (p < 0.001) antidiabetic potential in both diabetic models. BF significantly (p < 0.05) improved OGTT results in alloxanized diabetic mice and blocked the absorption of glucose from the gut. A significant (p < 0.001) increase in insulin levels and glycogen content in liver tissue and a decrease in plasma FFA, MDA, HbA1c, L-lactate, and pyruvate levels in STZ-diabetic mice were recorded. GC-MS and chromatographic analysis showed the presence of catechin, eugenol, longifolene, caryophyllene, Ar-tumerone and Geranyl-alpha-terpinene. Various metabolites with antidiabetic potential, including 4-hydroxycinnamyl alcohol 4-D-glucoside, zingerone glucoside, trans-trismethoxy resveratrol-d4, epigallocatechin 3-O-cinnamate, and β-glucogallin, were identified using UHPLC-MS. Animals treated with BF showed marked improvements in cellular structures of the pancreas, liver and kidneys. This fraction is non-mutagenic and protects the DNA. CONCLUSION The experimental fraction contained potential antidiabetic bioactive compounds responsible for alleviating diabetes-associated biochemical dysregulation. The fraction increased insulin levels and enhanced glycogen storage in muscles and the liver. It blocked glucose absorption from the intestine and substantially decreased HbA1c, lactate, pyruvate, free fatty acids, lipid, liver and kidney damage. Therefore, the use of BF for the treatment of type-2 diabetes may be beneficial.

Abstract
Over the past several decades, type 2 diabetes mellitus (T2DM) has been considered a global public health concern. Currently, various therapeutic modalities are available for T2DM management, including dietary modifications, moderate exercise, and use of hypoglycemic agents and lipid-lowering medications. Although the curative effect of most drugs on T2DM is significant, they also exert some adverse side effects. Biologically active substances found in natural medicines are important for T2DM treatment. Several recent studies have reported that active ingredients derived from traditional medicines or foods exert a therapeutic effect on T2DM. This review compiled important articles regarding the therapeutic effects of natural products and their active ingredients on islet β cell function, adipose tissue inflammation, and insulin resistance. Additionally, this review provided an in-depth understanding of the multiple regulatory effects on different targets and signaling pathways of natural medicines in the treatment of T2DM as well as a theoretical basis for clinical effective application.

Abstract
The diabetes-associated mortality rate is increasing annually, along with the severity of its accompanying disorders that impair human health. Worldwide, several medicinal plants are frequently urged for the management of diabetes. Reports are available on the use of medicinal plants by traditional healers for their blood-sugar-lowering effects, along with scientific evidence to support such claims. The Asteraceae family is one of the most diverse flowering plants, with about 1,690 genera and 32,000 species. Since ancient times, people have consumed various herbs of the Asteraceae family as food and employed them as medicine. Despite the wide variety of members within the family, most of them are rich in naturally occurring polysaccharides that possess potent prebiotic effects, which trigger their use as potential nutraceuticals. This review provides detailed information on the reported Asteraceae plants traditionally used as antidiabetic agents, with a major focus on the plants of this family that are known to exert antioxidant, hepatoprotective, vasodilation, and wound healing effects, which further action for the prevention of major diseases like cardiovascular disease (CVD), liver cirrhosis, and diabetes mellitus (DM). Moreover, this review highlights the potential of Asteraceae plants to counteract diabetic conditions when used as food and nutraceuticals. The information documented in this review article can serve as a pioneer for developing research initiatives directed at the exploration of Asteraceae and, at the forefront, the development of a botanical drug for the treatment of DM.

Pluchea indica Leaf Extract Alleviates Dyslipidemia and Hepatic Steatosis by Modifying the Expression of Lipid Metabolism-Related Genes in Rats Fed a High Fat-High Fructose Diet. Prev Nutr Food Sci 2022; 27:384-398. [PMID: 36721751 PMCID: PMC9843721 DOI: 10.3746/pnf.2022.27.4.384] [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: 05/26/2022] [Revised: 08/23/2022] [Accepted: 09/26/2022] [Indexed: 01/03/2023] Open
Abstract
This study evaluated the effect of Pluchea indica leaf extract (PIE) on dyslipidemia and lipid accumulation in the liver, emphasizing its molecular mechanisms in regulating lipid metabolism in rats fed a high fat-high fructose diet (HFFD). Male rats were fed HFFD (40% lard and 20% fructose) for ten weeks. They were then divided into four groups receiving distilled water, PIE (100 or 300 mg/kg/d), and pioglitazone (10 mg/kg/d) for a further six weeks, during which the HFFD was continued. After the experiment, fasting blood glucose (FBG), oral glucose tolerance (OGT), serum insulin and leptin levels, lipid profiles, and hepatic triglyceride content were measured. Histological examination and expression levels of lipid metabolism-related genes in the liver were measured. HFFD-fed rats indicated a significantly increased FBG, serum leptin, and homeostasis model assessment of insulin resistance (HOMA-IR) scores with impaired OGT and dyslipidemia compared to rats fed a normal diet. PIE significantly reduced FBG, serum leptin, and HOMA-IR scores and improved OGT. Additionally, PIE significantly improved dyslipidemia and decreased serum-free fatty acids and liver triglyceride content. Hepatic histological examination showed a marked reduction lipid accumulation in relation to HFFD controls. Interestingly, PIE significantly downregulated the expression of lipid synthesis-related genes and upregulated the expression of fatty-acid oxidation-related genes. In conclusion, PIE alleviates dyslipidemia and hepatic steatosis in HFFD rats plausibly by increasing insulin resistance and modifying the gene expression associated with lipid metabolism. PIE may be used as preventive nutrition for dyslipidemia and hepatic steatosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diabetes mellitus remains the most lethal metabolic disease of contemporaneous times and despite the therapeutic arsenal currently available, research on new antidiabetic agents remains a priority. In recent years, the revitalization of Thai Traditional Medicine (TTM) became a clear priority for the Thai government, and many efforts have been undertaken to accelerate research on herbal medicines and their use in medical services in various hospitals. Additionally, and particularly in rural areas, treatment of diabetes and associated symptomatology frequently relies on herbal preparations recommended by practitioners of TTM. In the current work, medicinal plants used in Thailand for treating diabetes, as well as their hypoglycaemic pharmacological evidences and potential therapeutic use for diabetes-related complications were reviewed. MATERIALS AND METHODS Ethnopharmacological information on the plant materials used in TTM for diabetes treatment was collected through literature search in a range of scientific databases using the search terms: diabetes, folk medicine, Thailand medicinal plants, traditional medicine. Information regarding scientific evidence on the antidiabetic effects of surveyed species was obtained considering not only the most common taxonomic designation, but also taxonomic synonyms, and including the keywords 'diabetes' and 'hypoglycaemic effect'. RESULTS A total of 183 species known to be used for diabetes management in TTM were reviewed, with 30% of them still lacking experimental evidences to support claims regarding the mechanisms and phytochemicals underlying their antidiabetic properties. Moreover, a total of 46 bioactives displaying effective antidiabetic effects have been isolated from 24 species, their underlying mechanism(s) of action being fully or partially disclosed. CONCLUSIONS We deliver the most extensive survey dealing with the ethnomedicinal knowledge of Thai medicinal plants utilized on diabetes management. We are certain that the current review will spark further research on Thai plants for the development of new standardized phytomedicines through drug discovery programmes.

Exp Ther Med 2020; 20:1385-1396. [PMID: 32742373 PMCID: PMC7388285 DOI: 10.3892/etm.2020.8877] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Accepted: 04/06/2020] [Indexed: 01/03/2023] Open
Abstract
Hyperglycemia-induced oxidative stress and inflammation are hallmarks of liver damage in diabetes mellitus. Accumulating evidence has demonstrated that Pluchea indica leaf ethanol extract (PILE) possesses strong antioxidant and anti-inflammatory properties. However, studies of its effects on liver damage in streptozotocin (STZ)-induced diabetic animals remain insufficient. To the best of our knowledge, the present study was the first to illustrate that PILE mitigated liver injury in STZ animals. Mice were first pretreated with PILE at either 50 mg/kg (PILE 50) or 100 mg/kg (PILE 100) 2 weeks prior to the induction of hyperglycemia by multiple low doses of STZ. The mice were then fed with PILE 50 or PILE 100 for 4 or 8 weeks, following which liver weight, pathological changes, oxidative stress parameters, inflammation-related markers and caspase-mediated apoptosis were measured at each time point. Untreated STZ mice exhibited abnormal increases in liver weight and severe pathological changes. However, PILE 100 reduced the severity of the STZ-induced diabetic phenotype at both time points. A significant decrease in the levels of superoxide dismutase and catalase, in addition to an increase in malondialdehyde, were observed in the livers of untreated STZ mice, all of which were significantly reversed by treatment with PILE 100 for 8 weeks. Western blot analysis revealed reduced levels of liver inflammatory markers, including interleukin-6, tumor necrosis factor-α, NF-κB p65, transforming growth factor-β1 and protein kinase C following PILE 100 treatment. Additionally, changes in the levels of apoptotic markers indicated that PILE 100 significantly attenuated caspase-9 and -3 expression, whilst preserving that of the Bcl-2 protein. In conclusion, the present study revealed that PILE alleviates hyperglycemia-induced liver injury by normalizing the various mediators of oxidative stress, inflammation and apoptosis.
