Antidiabetic effects of Brugmansia aurea leaf extract by modulating the glucose levels, insulin resistance, and oxidative stress mechanism. Front Nutr 2022; 9:1005341. [PMID: 36304231 PMCID: PMC9592987 DOI: 10.3389/fnut.2022.1005341] [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: 07/29/2022] [Accepted: 09/09/2022] [Indexed: 11/17/2022] Open
Abstract
Background Ethnopharmacological relevance: Brugmansia, a genus of the Solanaceae family, has historically been utilized in many different parts of the world as an anti-inflammatory for treating skin infections, wounds, and bodily aches and pains. The current study aimed to investigate the potential benefits of a methanolic extract of Brugmansia aurea in the management of diabetes and underlying complications in alloxanized-induced diabetic rats. Materials and methods Animals were divided into nine groups (n = 6). Four groups received different standard oral hypoglycemic agents; three groups received 100, 200, and 400 mg/kg of B. aurea leaf extract for six consecutive weeks, and the remaining two were normal and disease control groups. All groups received alloxan (150 mg/kg) except for the normal control. Only those animals whose glucose levels were raised to 200 mg/dl were selected for the study. After a 6-week dosage period, various biochemical parameters, as well as HbA1c, antioxidant profile, oral glucose tolerance test (OGTT), insulin sensitivity, histopathology, and insulin resistance, were measured and compared with the untreated diabetic group. Results Brugmansia aurea leaf extract at a dose of 400 mg/kg showed potent antidiabetic activity by reducing blood glucose levels (p < 0.001) after 6 weeks of treatment. OGTT data showed that B. aurea exhibited significant (p < 0.001) glucose tolerance by significantly reducing blood glucose levels in just 2 h post-treatment. Other tests showed that plant extract significantly increased (p < 0.001) insulin sensitivity and decreased (p < 0.001) insulin resistance. The biochemical profile showed reduced triglyceride and cholesterol, while the antioxidant profile showed restoration of antioxidant enzymes in the pancreas, kidney, and liver tissues of treated rats. Conclusion The present study indicated that crude extracts of B. aurea increase insulin sensitivity and reduce hyperlipidemia in diabetic rats, which rationalizes the traditional medicinal use of this plant as an antidiabetic agent.

Abstract
COVID-19 has become the focal point since 2019 after the outbreak of coronavirus disease. Many drugs are being tested and used to treat coronavirus infections; different kinds of vaccines are also introduced as preventive measure. Alternative therapeutics are as well incorporated into the health guidelines of some countries. This research aimed to look into the underlying mechanisms of functional foods and how they may improve the long-term post COVID-19 cardiovascular, diabetic, and respiratory complications through their bioactive compounds. The potentiality of nine functional foods for post COVID-19 complications was investigated through computational approaches. A total of 266 bioactive compounds of these foods were searched via extensive literature reviewing. Three highly associated targets namely troponin I interacting kinase (TNNI3K), dipeptidyl peptidase 4 (DPP-4), and transforming growth factor beta 1 (TGF-β1) were selected for cardiovascular, diabetes, and respiratory disorders, respectively, after COVID-19 infections. Best docked compounds were further analyzed by network pharmacological tools to explore their interactions with complication-related genes (MAPK1 and HSP90AA1 for cardiovascular, PPARG and TNF-alpha for diabetes, and AKT-1 for respiratory disorders). Seventy-one suggested compounds out of one-hundred and thirty-nine (139) docked compounds in network pharmacology recommended 169 Gene Ontology (GO) items and 99 Kyoto Encyclopedia of Genes and Genomes signaling pathways preferably AKT signaling pathway, MAPK signaling pathway, ACE2 receptor signaling pathway, insulin signaling pathway, and PPAR signaling pathway. Among the chosen functional foods, black cumin, fenugreek, garlic, ginger, turmeric, bitter melon, and Indian pennywort were found to modulate the actions. Results demonstrate that aforesaid functional foods have attenuating roles to manage post COVID-19 complications. PRACTICAL APPLICATIONS: Functional foods have been approaching a greater interest due to their medicinal uses other than gastronomic pleasure. Nine functional food resources have been used in this research for their traditional and ethnopharmacological uses, but their directive-role in modulating the genes involved in the management of post COVID-19 complications is inadequately studied and reported. Therefore, the foods types used in this research may be prioritized to be used as functional foods for ameliorating the major post COVID-19 complications through appropriate science.

Abstract
Abstract
Fenugreek has a long tradition of use as a medicine and also has been commonly used as food in many countries. This plant is well known, especially in Asia. In Europe, fenugreek seeds are regarded as a traditional herbal medicine consumed in case of loss of appetite and in confirmed skin inflammations. Trigonella foenum-graecum seeds contain wide spectrum of different biologically active constituents which affect the properties of preparations produced from this plant. Numerous preclinical studies confirm the use of fenu-greek as a hypolipidemic and lowering blood glucose level drug. Unfortunately, there are not many clinical studies on fenugreek seeds in this area. Published studies often significantly differ in the amount and type of fenugreek seed preparation used. However, results of available scientific research are promising and suggest the possibility of using fenugreek seeds in metabolic syndrome therapy. Undoubtedly, further research is required to confirm such properties of Trigonella foenum-graecum.

Abstract
Prevention and delay in the onset of memory disorders will have a great impact on society by reducing the disease burden and finances. Drugs available for the treatment of learning and memory disorders are few. There is need to develop a better drug, several studies have shown the therapeutic effectiveness of herbal extracts for the learning and memory disorders because of their neuroprotective effects, hence herbs should be evaluated scientifically to form a basis for the future discovery of newer drugs. In this study, effect of Trigonella-foenum graecum L. seeds methanol extract (TFGS-ME) was evaluated in mice on learning and memory process by both exteroceptive and interoceptive behavioral models at three different doses. Elevated plus maze test was employed to assess the effect on learning and memory as an exteroceptive behavioral test. Scopolamine-induced amnesia was performed to assess effect on learning and memory as interoceptive behavior test. In both tests, it was found that animals received extract at 200 mg/kg exhibited a highly noteworthy decline in transfer latency on both acquisition and retention days in contrast to control animals, suggestive of improved learning and memory process. Results were equivalent to the standard drug piracetam at similar dose indicating that TFGS-ME improves learning and memory process and has significant potential as an antiamnesic agent. Hence there is need to separate the dietary components which may play a vibrant role in the future invention of novel drugs.

Abstract
The antidiabetic activity of various subfractions of the alcohol extract of the bark of Pterocarpus marsupium Roxb. was evaluated in alloxan-induced diabetic rats. The effect of these extracts on lipid profile and liver function tests were also assessed to evaluate their activity in controlling diabetes related metabolic alterations. The parameters measured were plasma glucose, total protein, cholesterol, triglycerides, alkaline phosphatase, SGOT and SGPT. The results indicate the effective role of Pterocarpus marsupium on the above mentioned parameters indicating that Pterocarpus marsupium can also control the diabetes related metabolic alterations apart from controlling the glucose levels. Among the fractions tested the butanol subfraction was found to be more active in comparison with other subfractions. It can be concluded that the butanol subfraction of the alcohol extract of Pterocarpus marsupium exhibits significant antidiabetic activity and corrects the metabolic alterations in diabetic rats and this activity may resemble insulin-like properties.

Abstract
OBJECTIVE The objective of this study was to evaluate the potential antifertility activity of feeding diets containing 30% fenugreek seeds to male and female white New Zealand rabbits. RESULTS The data presented in this study clearly demonstrate an antifertility effect of fenugreek seeds in the female rabbits and more of a toxicity effect in the male rabbits. In males, testis weight was reduced, with evident damage to the seminiferous tubules and interstitial tissues as shown by the histopathology of testis tissue sections. In addition, the plasma concentration of the androgen hormone and sperm concentrations were halved in the treated animals. In the case of the females, there was evidence of a significant reduction of developing fetuses as observed by reductions of both fetal and placental weights at 20 days of gestation and of the litter size. This was further supported histopathologically by the observed proliferative changes of the endometrial glands. The circulating plasma progesterone concentrations at 10 and 20 days of gestation significantly increased with no significant effect on the prebreeding estrogen concentrations in the treated animals.

Abstract
Increased human use of fenugreek seeds (Trigonella foenum graecum) entails the generation of toxicity data in experimental animals. In this investigation, toxic effects of debitterized fenugreek (DFG) powder have been assessed following acute and subchronic regimens in mice and rats. In the acute study, DFG powder intragastrically administered to albino mice (CFT-Swiss, Mus musculus) and albino rats (CFT-Wistar, Rattus norvegicus) of both sexes failed to induce any signs of toxicity or mortality up to a maximum practical dosage of 2 and 5 g/kg body weight, respectively. Further, no significant alterations either in relative organ weights or their histology were discernible at terminal autopsy. In the 90-day subchronic study, DFG fed to weanling rats of both sexes at dietary doses of 0, 1, 5 and 10% in a pure diet had no effect either on the daily food intake or growth. Terminal autopsy revealed no alterations in relative organ weights of various vital organs, or their histoarchitecture. Haematological constants in DFG-fed rats were on par with those of controls. Further, biochemical measurements in serum and liver of DFG-fed rats revealed no appreciable changes in various parameters such as enzyme levels of GPT , GOT and ALP, as well as many serum constituents such as proteins, cholesterol, urea and creatinine at any of the dietary levels. From these results, it may be concluded that DFG does not produce any significant acute and cumulative toxicity at the doses administered, as reflected by the various parameters investigated.

Abstract
The seeds of fenugreek (Trigonella foenum graecum L.) are traditionally assumed to have restorative properties. We have recently shown that a fenugreek seed extract containing steroid saponins increased food consumption and induced hypocholesterolemia in rats. This study aims to investigate the specific role of purified steroid saponins in these properties. For this purpose, an original technique for extraction and purification of steroid saponins was carried out. Thereafter, the effects of these steroid saponins were investigated on feeding behavior and metabolic endocrine changes in normal and diabetic rats. All the steroid saponins (furostanol type) were extracted from the seeds and separated from all other constituents of the entire extract by using several purification procedures to give an extract containing at least 90% of steroid saponins. Pharmcological experiments were performed in vivo in normal and streptozotocin diabetic rats: steroid saponins were administered chronically mixed with food (12.5 mg/day per 300 g body weight). Our data show that the treatment with steroid saponins significantly increased food intake and the motivation to eat in normal rats, while modifying the circadian rhythm of feeding behavior; it also stabilized the food consumption in diabetic rats, which resulted in a progressive weight gain in these animals, in contrast to untreated diabetic controls. Both in normal and diabetic rats, steroid saponins decreased total plasma cholesterol without any change in triglycerides. In conclusion, the present work reports a clear methodology to obtain all the steroid saponins and demonstrates that these saponins enhance food consumption and motivation to eat, and reduce plasma cholesterol levels in rats.

Abstract
Fenugreek seeds (Trigonella foenum graecum L.) are assumed to have restorative and nutritive properties. The present work was designed to investigate the effects of a fenugreek seed extract on feeding behaviour. Experiments were performed to determine food consumption and motivation to eat as well as metabolic-endocrine changes in chronically treated animals. Male Wistar rats were given the seed extract orally (10 and 100 mg/day per 300 g body weight), mixed together with food, and control animals were monitored in parallel. The results show that chronic oral administration of the fenugreek extract significantly increases food intake and the motivation to eat. The treatment, however, does not prevent the anorexia nor the decreased motivation to eat induced by d-fenfluramine (2 mg/kg, IP). An increase in plasma insulin and a decrease in total cholesterol and very low-density lipoprotein (VLDL)-low-density lipoprotein (LDL) total cholesterol were also observed. In conclusion, chronic administration of a fenugreek seed extract enhances food consumption and motivation to eat in rats and also induces hyperinsulinemia as well as hypocholesterolemia.

Abstract
The transformation of fenugreek subfractions, rich in steroid saponins, was studied upon their passage through the digestive tract to determine the contribution of saponins and/or diosgenin and other steroid sapogenins to the hypocholesterolemic effect of fenugreek seeds. Feces of alloxan diabetic dogs fed fenugreek subfractions were analyzed, and diosgenin, smilagenin and gitogenin were identified and measured using capillary gas chromatography/mass spectrometry. Our results show that saponins are, in part (about 57%), hydrolyzed into sapogenins in the digestive tract. It appears that saponins may be implicated, alone or together with diosgenin, in the observed hypocholesterolemic effect of fenugreek seeds in diabetic dogs.
