Evaluation of fenugreek (Trigonella foenum-graecum L.) powder supplementation on metabolic syndrome, oxidative stress and inflammation in high fat diet fed rats

As an anti-diabetic medicinal plant, fenugreek seed (FG) (Trigonella foenum-graecum L.) has long been utilized and has many therapeutic uses. The current investigation sought to ascertain the effects of FG powder supplementation on insulin resistance, dyslipidemia, and oxidative stress in rats given a high-fat (HF) diet. Measurements of biochemical and antioxidant indicators were made in animal blood and tissue samples, including malondialdehyde (MDA), nitric oxide (NO), advanced oxidation protein product (AOPP), reduced glutathione (GSH), superoxide dismutase (SOD), triglycerides (TG), and catalase (CAT). Furthermore, the tissues of the kidney, heart, and liver were stained histologically. HF diet feeding in rats declined in antioxidant enzyme activities, along with a rise in MDA and other indicators of oxidative stress, which were mitigated by the supplementation of FG. Additionally, FG supplementation enhanced the expression of genes corresponding to antioxidants in the liver of rats given HF diet. FG supplements in HF diet-fed rats displayed altered gene expression in the livers that metabolized fat. Histological staining of the liver demonstrated that FG supplementation reduced necrosis and the accumulation of fat droplets in the liver of rats given HF diets. In conclusion, this finding showed that FG supplementation in HF diet fed rats reduced the plasma lipids, decreased oxidative stress and raised antioxidant enzyme activities. FG may therefore aid in reducing the chronic complications linked to the HF diet in experimental rats.

An appraisal of the Zulu antidiabetic medicinal plants

Diabetes mellitus is a chronic metabolic disorder that affects millions of people worldwide. Its conventional management involves diet modification, exercise, and majorly the use of synthetic drugs, which may be ineffective, have adverse effects, and of relatively expensive costs. To mitigate the downsides of the available treatments, alternative therapies from medicinal plants are commonly sought by different ethnic groups including the Zulus. This paper appraised the antidiabetic plants used by the Zulus, their local and botanical names, the parts commonly used, isolated bioactive principles and their reported mechanisms of action. 38 plants covering 20 families were identified with Asteraceae accounting for 31.57 % and the leaves was the most used plant part (50 %). Out of the 38 plants identified, 28 have been scientifically validated using in vitro/in vivo models but identifying the plant with the most potent hypoglycemic activity remains challenging due to variations in biological activities. Important antidiabetic agents such as quercetin, squalene, kaempferol, isomukaadial acetate, phytol, sitosterol, apigenin, catechin and their derivates have been isolated and characterized from the verified plants though, more scientific exploration is required to develop these principles into valuable antidiabetic medications with establish mechanism of action. Scientists therefore needs to beam their searchlight and dedicate resources to the rich botanicals of the Zulu land with the view to providing indigenous solutions that can be incorporated into modern medicine for diabetes management.

The use of medicinal plants is integral to addressing liver, heart, lung, and other metabolic issues. These plants are rich in vitamins, minerals, flavonoids, and alkaloids, which collectively help in lowering intestinal glucose absorption and increasing insulin secretion by pancreatic tissues. Elemental analysis, encompassing major, minor, and trace elements, was performed on various parts (leaves, roots, and seeds) of 16 anti-diabetic medicinal plants collected from different regions of Swat and Peshawar in Khyber Pakhtunkhwa (KPK), Pakistan. This analysis utilized proton-induced X-ray emission (PIXE) and inductively coupled plasma optical emission spectroscopy (ICP-OES) techniques. Our PIXE and ICP-OES analysis revealed the presence of major (Ca, K, S, P), minor (Si, Cl), and trace (Al, Mn, Fe, Ni, Cu, Zn, Se, Cr, and Sc) elements in various parts (leaves, roots, and seeds) of the 16 anti-diabetic medicinal plants studied. Specifically, elements such as Ca, K, Cr, Cu, Mn, Zn, and Se were detected, all of which are known to contribute in maintaining normal glucose metabolism. Notably, Zn and Se are crucial trace elements for the synthesis, secretion, and action of insulin. Significant Zn concentrations were observed in ten anti-diabetic medicinal plants: Albizia lebbeck (AL), Atropa acuminata (AA), Avena fatua (AF), Citrus medica (CM), Commiphora wightii (CW), Cymbopogon citratus (CC), Daucus carota (DC), Ziziphus mauritiana (FM), Hyoscyamus niger (HN), and Martynia annua (MA), and significant Se concentrations were observed in twelve medicinal plants, i.e., Albizia lebbeck (AL), Allium sativum (AS), Atropa acuminata (AA), Avena fatua (AF), Cannabis sativa (CS), Capparis spinosa (CaS), Commiphora wightii (CW), Cymbopogon citratus (CC), Datura alba (DA), Daucus carota (DC), Ziziphus mauritiana (FM), and Hyoscyamus niger (HN). Our study's elemental analysis using PIXE and ICP-OES on various parts of 16 medicinal plants identified a significant number of useful elements. Elements such as Ca, K, S, P, Al, Si, Cl, Mn, Fe, Ni, Cu, Zn, Se, and Cr were identified and quantified. These findings support the potential use of these plants in managing diabetes and highlight the importance of elemental profiling in understanding their therapeutic properties.

A Review of Antidiabetic Medicinal Plants as a Novel Source of Phosphodiesterase Inhibitors: Future Perspective of New Challenges Against Diabetes Mellitus.

Intracellular glucose concentration plays a crucial role in initiating the molecular secretory process of pancreatic β-cells through multiple messengers and signaling pathways. Cyclic nucleotides are key physiological regulators that modulate pathway interactions in β -cells. An increase of cyclic nucleotides is controled by hydrolysed phosphodiesterases (PDEs), which degrades cyclic nucleotides into inactive metabolites. Despite the undeniable therapeutic potential of PDE inhibitors, they are associated with several side effects. The treatment strategy for diabetes based on PDE inhibitors has been proposed for a long time. Hence, the world of natural antidiabetic medicinal plants represents an ideal source of phosphodiesterase inhibitors as a new strategy for developing novel agents to treat diabetes mellitus. This review highlights medicinal plants traditionally used in the treatment of diabetes mellitus that have been proven to have inhibitory effects on PDE activity. The contents of this review were sourced from electronic databases, including Science Direct, PubMed, Springer Link, Web of Science, Scopus, Wiley Online, Scifinder and Google Scholar. These databases were consulted to collect information without any limitation date. After comprehensive literature screening, this paper identified 27 medicinal plants that have been reported to exhibit anti-phosphodiesterase activities. The selection of these plants was based on their traditional uses in the treatment of diabetes mellitus. The review emphasizes the antiphosphodiesterase properties of 31 bioactive components derived from these plant extracts. Many phenolic compounds have been identified as PDE inhibitors: Brazilin, mesozygin, artonin I, chalcomaracin, norartocarpetin, moracin L, moracin M, moracin C, curcumin, gallic acid, caffeic acid, rutin, quercitrin, quercetin, catechin, kaempferol, chlorogenic acid, and ellagic acid. Moreover, smome lignans have reported as PDE inhibitors: (+)-Medioresinol di-O-β-d-glucopyranoside, (+)- Pinoresinol di-O-β-d-glucopyranoside, (+)-Pinoresinol-4-O-β-d-glucopyranosyl (1→6)-β-dglucopyranoside, Liriodendrin, (+)-Pinoresinol 4'-O-β-d-glucopyranoside, and forsythin. This review provides a promising starting point of medicinal plants, which could be further studied for the development of natural phosphodiesterase inhibitors to treat diabetes mellitus. Therefore, it is important to consider clinical studies for the identification of new targets for the treatment of diabetes.

Phytochemicals profiling, in vitro and in vivo antidiabetic activity, and in silico studies on Ajuga iva (L.) Schreb.: A comprehensive approach

Abstract Ajuga iva (L.) Schreb. is a well-known antidiabetic medicinal plant used for several traditional medicine aspects in different areas of the world, including Libya. This study includes phytochemical analysis, antidiabetic evaluation, and in silico studies of the plant, A. iva, growing in Libya. The constituents of the plant were profiled using LC-MS/MS-QTOF analysis, and a total of 28 compounds were tentatively identified, including engeletin, pyrocatechol, eriodyctiol-7-hexoside, and 3,4-dihydroxybenzaldehyde, as major constituents. In addition, the steroidal compounds, i.e., 20-hydroxyecdysone, 24-dehydroprecyasterone, makisterone A, and ajugasterone D, which are considered chemomarkers for the plant, were also annotated by LC-MS analysis. The plant extract induced inhibition of α-amylase and α-glucosidase enzymes at IC50 values of 0.18 and 0.12 mg/mL, compared to the IC50 of the standard acarbose at 0.11 and 0.09 mg/mL, respectively. Fasting blood glucose (FBG, 360.7 mg/dL) levels were significantly reduced by the treatment of streptozotocin (STZ)-diabetic animals with 400 mg/kg (140.5 mg/dl) and 500 mg/kg (112.3 mg/dL) doses of the plant extract. The plant extract also induced a significant (p < 0.01) increase in insulin serum level compared to the untreated diabetic rats; however, the higher dose of the plant induced similar insulin induction compared to glibenclamide. Histopathological examination of the pancreatic and liver tissues indicated that A. iva extract induced regeneration in the islets of Langerhans and liver cells compared to the untreated diabetic rats. Docking analysis demonstrated that eriodyctiol-7-hexoside, echinacoside, and 2″-galloylhyperin showed the lowest binding energies to the target sites of α-amylase and α-glucosidase enzymes, indicating their potential role in A. iva antidiabetic bioactivities. The results support the recorded traditional bioactivity of A. iva as an antidiabetic herb, whereas its contents of polyphenols play a major role in the plant’s antidiabetic effect.

Insulin-sensitizing and antioxidant effects of <i>Ethulia</i> <i>conyzoïdes</i> aqueous extract in dexamethasone-induced insulin resistant rats

Rising the prevalence of type 2 diabetes mellitus in sub-saharian Africa has necessitated surveys of antidiabetic medicinal plants. Ethulia conyzoïdes is a plant widely used in traditional medicine to treat diabetes. However, the different mechanisms by which it exerts its antidiabetic effects remain unknown. Thus, this study aimed to investigate the effect of Ethulia conyzoïdes aqueoux extract on dexamethasone-induced insulin resistance in Wistar rats. Insulin resistance was induced by intraperitoneal injection of dexamethasone (1mg/kg) for 8 days and the animals received simultaneously, orally, distilled water (insulin resistant control group) and, metformin (100 mg/kg) or Ethulia conyzoïdes aqueoux extract at doses of 133 and 266 mg/kg. Normal control rats received NaCl 0.9% (intraperitoneal by injection) and distilled water orally. Insulin sensitivity, total cholesterol, triglycerides, transaminases activity and redox status were evaluated. Results showed a significant reduction of insulin tolerance (p<0.001), a drastic increased of transaminase activity (p<0.05), hyperlipidemia, and a great potentiation of liver antioxidant enzymes (GSH, SOD and catalase) in insulin resistant control group. Ethulia conyzoïdes aqueoux extract markedly improved insulin sensitivity and reversed all the modified parameters. This study demonstrated the efficacy of Ethulia conyzoïdes aqueoux extract to improve insulin sensitivity and manage biochemical disorders induced by insulin resistance. Short term administration of dexamethasone appears to stimulate the first line antioxidant defense in order to counteract oxidative stress, meaning that Ethulia conyzoïdes aqueoux extract inhibited free radicals production.

Anti-protein glycation and free-radical scavenging properties of Sri Lankan antidiabetic medicinal plant Salacia reticulata l. (Kothala Himbutu)

BackgroundDecoctions of the root and stem of the medicinal plant Salacia reticulata is an indigenous remedy for diabetics and its complications in Sri Lanka. In diabetics, the formation of advanced glycation end products (AGEs) leads to many pathologies. Nevertheless, the anti-protein-glycation property of this plant is poorly documented. This study reports the anti-protein-glycation and radical scavenging potential of various plant parts of S. reticulata.MethodsHot water extracts (2g dried powder/50 ml) of root, stem, leaf, twigs, and fruits at various concentrations (15.6 to 500.0 µg/ml) were subjected to anti-glycation and glycation reversing assays in vitro. 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was used for free radical scavenging property.ResultsVarious plant parts of S. reticulata showed anti-protein-glycation and free-radical scavenging activities. IC50 for the anti-glycation activity of root, stem, leaf, twigs, and fruit extracts were 11.92 ± 1.14, 35.18 ± 2.79, 113.3 ± 1.91, 149.59 ± 1.06, and 1120.37 ± 229.48 µg/ml respectively. IC50 of Rutin was 21.88 ± 2.82 µg/ml. EC50 of the root, stem, twigs, and leaf extracts for glycation reversing was 102.09 ± 6.23, 116.99 ± 5.82, 154.45 ± 5.79, and 278.78 ± 14.19 µg/ml respectively. The EC50 values for the radical scavenging activity of leaf, stem, and roots were 26.4±4.7, 9.0±1.2, and 9.1±1.3 respectively. Root had significantly (p<0.05) high activity for all the parameters tested.ConclusionSalacia reticulata possess anti-glycation, glycation-reversing, and free radical scavenging activities. Other than root and stem, the leaves and twigs too may be a useful source for anti-diabetic bioactive molecules.

Phytochemical Content and Antidiabetic Properties of Most Commonly Used Antidiabetic Medicinal Plants of Kenya.

Traditional medicinal plants have been used for decades in folk medicines in the treatment and management of several ailments and diseases including diabetes, pain, ulcers, cancers, and wounds, among others. This study focused on the phytochemical and antidiabetic activity of the commonly used antidiabetic medicinal species in Kenya. Phytochemical profiling of these species revealed flavonoids and terpenoids as the major chemical classes reported which have been linked with strong biological activities against the aforementioned diseases, among others. However, out of the selected twenty-two species, many of the natural product isolation studies have focused on only a few species, as highlighted in the study. All of the examined crude extracts from thirteen antidiabetic species demonstrated strong antidiabetic activities by inhibiting α-glucosidase and α-amylase among other mechanisms, while nine are yet to be evaluated for their antidiabetic activities. Isolated compounds S-Methylcysteine sulfoxide, quercetin, alliuocide G, 2-(3,4-Dihydroxybenzoyl)-2,4,6-trihydroxy-3 (2H)-benzofuranone, Luteolin-7-O-D-glucopyranoside, quercetin, 1,3,11α-Trihydroxy-9-(3,5,7-trihydroxy-4H-1-benzopyran-7-on-2-yl)-5α-(3,4-dihydroxy-phenyl)-5,6,11-hexahydro-5,6,11-trioxanaphthacene-12-one and [1,3,11α-Trihydroxy-9-(3,5,7-trihydroxy-4H-1-benzopyran-7-on-2-yl)-5α-(3,4-dihydroxy-phenyl)-5,6,11-hexahydro-5,6,11-trioxanaphthacene-12-one]-4'-O-D-gluco-pyranoside from Allium cepa have been found to exhibit significant antidiabetic activities. With the huge number of adults living with diabetes in Kenya and the available treatment methods being expensive yet not so effective, this study highlights alternative remedies by documenting the commonly used antidiabetic medicinal plants. Further, the study supports the antidiabetic use of these plants with the existing pharmacological profiles and highlights research study gaps. Therefore, it is urgent to conduct natural products isolation work on the selected antidiabetic species commonly used in Kenya and evaluate their antidiabetic activities, both in vitro and in vivo, to validate their antidiabetic use and come up with new antidiabetic drugs.

Gynura procumbens leaves are used as an anti-diabetic medicinal plant in Southeast Asia. A 28-day feeding trial was conducted to evaluate the effects of Gynura procumbens (GP) leaf meal on growth performance, glucose level, lipid profile and mineral content in alloxan-induced diabetic mice. A total of thirty-six mice at 14 days old were assigned to four treatment groups: NC (Normal Control), T0 = Control (Basal diet), T1 = (Basal diet + 0.5% Dry leaf on DM basis), T2 = (Basal diet + 1.0% Dry leaf on DM basis) having three replications consisting of nine mice in each in a completely randomized design. The results showed that glucose level was significantly (P&lt;0.01) reduced during the last 3 weeks compared to control of alloxan-induced mice. Three weeks of dietary supplementation of GP leaf at 0.5% and 1.0% levels significantly (P&lt;0.05) increased body weight during the second and the third week whereas decreased, feed intake and water intake of alloxan-induced diabetic mice. A significant reduction of cholesterol, triglycerides (TG), low density lipoproteins (LDL) while increased high density lipoproteins (HDL) of induced mice compared to control (P&lt;0.001). There were no significant variations in blood phosphorus, Ca and total protein. Moreover, in the proximate CHO, crude protein, crude fat increased while ash, moisture, crude fibre decreased in treatment groups compared to the basal diet. Overall, GP leaf showed trustworthy results on anti-diabetic effects included lipid profile.

Modulatory Effect of Medicinal Plants and Their Active Constituents on ATP-Sensitive Potassium Channels (KATP) in Diabetes.

Hyperglycemia, which is a chronic metabolic condition caused by either a defect in insulin secretion or insulin resistance, is a hallmark of diabetes mellitus (DM). Sustained hyperglycemia leads to the onset and development of many health complications. Despite the number of available antidiabetic medications on the market, there is still a need for novel treatment agents with increased efficacy and fewer adverse effects. Many medicinal plants offer a rich supply of bioactive compounds that have remarkable pharmacological effects with less toxicity and side effects. According to published evidence, natural antidiabetic substances influence pancreatic β-cell development and proliferation, inhibit pancreatic β-cell death, and directly increase insulin output. Pancreatic ATP-sensitive potassium channels play an essential role in coupling glucose metabolism to the secretion of insulin. Although much of the literature is available on the antidiabetic effects of medicinal plants, very limited studies discuss their direct action on pancreatic KATP. The aim of this review is to focus on the modulatory effects of antidiabetic medicinal plants and their active constituents on pancreatic KATP. The KATP channel should be regarded as a key therapeutic milestone in the treatment of diabetes. Therefore, continuous research into the interaction of medicinal plants with the KATP channel is crucial.

Beneficial Synergistic Effect of Supplementation with Combined M. oleifera and L. speciosa Leaf Capsules in Patients with Type 2 Diabetes

Diabetes mellitus is a metabolic non-communicable chronic disease in which the body's ability to process glucose is impaired, resulting in higher blood glucose levels. If not controlled, this disease can lead to severe complications. Various plants with medicinal properties can treat chronic diseases, such as diabetes, due to therapeutically important phytochemicals and bioactive compounds. This study investigated the effect of antidiabetic medicinal plant leaves in controlling blood glucose levels among Wakhi diabetic patients in the Hunza district of Pakistan. The "Wakhis" are an ethnic group living in the remote region of Pakistan. The method used in this study was a placebo-controlled study. Leaf powders of Moringa oleifera and Lagerstroemia speciosa were filled in capsules of 1000 mg each. The antidiabetic potential of the medicinal plants was estimated by performing the biochemical blood profiles of diabetic patients before and after the trial. After the intervention, the level of glycated hemoglobin (HbA1c) reduced from 8.3±1.8 to 7.5±1.2% significantly (P = 0.0401). The fasting blood sugar (FBS) in the intervention group reduced significantly from 191±49 mg/dL to 169±41 mg/dL (P = 0.0041) after the trial. According to the findings of this study, the combined herbal capsules effectively controlled the blood sugar of type 2 diabetic patients. Conclusively, the combination of M. oleifera and L. speciosa have the potential to lower blood sugar levels supplementary to existing regimens. Further investigation is warranted to explore the mechanism resulting in the observed reduction in sugar levels in type 2 diabetic patients.

Ethnobotanical Study of Medicinal Plants used by Traditional Health Practitioners to Manage Diabetes Mellitus in Safi and Essaouira Provinces (Central-Western Morocco)

The Moroccan population heavily rely on herbal remedies to control diabetes mellitus. The population of the central-western region of Morocco uses a&nbsp; number of anti-diabetic medicinal plants, but there is a lack of good&nbsp; ethnobotanical information on these plants. Thus, the present survey was&nbsp; conducted in the Safi and Essaouira provinces to inventory the main medicinal&nbsp; plants used in folk medicine to treat diabetes mellitus. Seventy-seven traditional&nbsp; health practitioners were interviewed face-to-face throughout&nbsp; different sites in the study area. The data were analyzed using relative&nbsp; frequency of citation (RFC), Jaccard index (JI), Jaccard distance, and Sorensen's&nbsp; similarity index (QS). In total, 84 plants species belonging to 41 families were&nbsp; reported. Lamiaceae, Fabaceae, Apiaceae, and Asteraceae were reported as the&nbsp; most represented families. Eight taxa were described for the first time for&nbsp; treating diabetes mellitus. The most frequently cited plants species were&nbsp; Trigonella foenum-graecum L., Artemisia herba-alba Asso, Olea europaea&nbsp; subsp. europaea L., Allium sativum L., and Origanum compactum Benth. Leaves&nbsp; and fruits were the most cited plant parts used, and decoction and infusion&nbsp; were the preferred modes of preparation. As for the level of similarity to other&nbsp; regions of Morocco, the province of Tarafaya in the south seems to be the most&nbsp; like the study area (JI=36.94). The current survey represents a valuable&nbsp; contribution that can help preserve ethnobotanical knowledge in this area as&nbsp; well as explore medicinal plant, phytochemical, and pharmacological potential.&nbsp

Phytochemical Screening, GC-MS and FTIR analysis of Bioactive Compounds in Methanolic Leaf Extracts of Costus igneus (CIMLE) as a Natural Source of Drug Lead Molecules for Next-generation Drug-design, Development and Therapeutics

Diabetes mellitus (DM) is a metabolic disorder that affects people of all ages. Increased prevalence of diabetes worldwide has led to the development of synthetic drugs to provide an interim solution to the ill effects of the issue. However, such drugs, although effective as antihyperglycemic agents, are accompanied by significant side effects, costly, and inaccessible to majority of people in remote in underdeveloped countries. Local medicinal plants have been used by such indigenous people through ages to treat such complicate ailments due to their ease of availability and GRAS nature. As diabetes continues to become prevalent, health care practitioners are considering PBNPs as a potential source of antidiabetic drugs due to their high potency and fewer side effects. To better understand the mechanism of action of medicinal plants, their active phytoconstituents are being isolated and investigated thoroughly. Phytochemical screening followed by GCMS analysis of methanolic leaf extracts of Costus igneus depicted the presence of 19 bioactive compounds viz., Bicyclo [3.1.1]heptane, 2,6,6- trimethyl-; 2-Pentadecanone, 6,10,14-trimethyl-; phthalic acid; 3,7,11,15-Tetramethyl-2-hexadecen- 1-ol; 5,9,13-Pentadecatrien-2-one, 6,10,14- trimethyl; 2(3H)-Furanone,dihydro-5-methyl-5- pentyl; Hexamethyl-2,6,10,14,18,22- tetracosahexaen-1-yl]-6-methox.; Oxalic acid, cyclohexyl isohexyl ester; 6-Octadecenoic acid; Phytol; 4,8,12,16-Tetramethylheptadecan-4- olide; 5-methyl-2,3-dihydro-1H-indole; Bis(2-ethylhexyl) phthalate; Adamantane-1-carboxylic acid methyl ester; Benzopyran-6-ol,3,4-dihydro-; Benzoquinoline; gamma-Tocopherol; dimethyl-5,5'-diphenyl-1H,; 1H-benzo[b]furo[2,3-f]indole that may be ADMET predicted for potential biomedical application in the treatment of diabetics and long term complications associated with the disease. &#x0D; Keywords: Costus igneus; CIMLE; GCMS; Phytochemical Screening; Antidiabetic Leads; NDDT; Antidiabetic Medicinal Plant
