Heliyon 2023; 9:e15488. [PMID: 37180914 PMCID: PMC10173408 DOI: 10.1016/j.heliyon.2023.e15488] [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: 11/03/2022] [Revised: 04/02/2023] [Accepted: 04/12/2023] [Indexed: 05/16/2023] Open
Abstract
Objective This study aimed to develop an effective alternative medicine with multi potential herbs against polycystic ovarian syndrome (PCOS) in rats induced by letrozole treatment. Materials and method Polyherbal syrup was prepared with a combination of S. asoca bark, G. sylvestre leaves, P. daemia aerial parts, C. zeylanium stem bark, C. bonduc seeds, and W. somnifera roots ethanolic extract. In vitro cell viability study, adenosine monophosphate-activated protein kinase (AMPK), and glucose transporter 4 (GLUT4) gene expression assay were carried out on the Chinese Hamster Ovarian (CHO) cell line. For the PCOS induction letrozole (1 mg/kg p. o.) was given for 21 consecutive days. The PCOS induction was confirmed by measuring estrus irregularity, insulin resistance by oral glucose tolerance test (OGTT), and hyperandrogenism by measuring serum total testosterone level 21 days after completion of letrozole treatment. After induction of PCOS, metformin (155 mg/kg p. o.), and polyherbal syrup (100 mg/kg, 200 mg/kg, and 400 mg/kg p. o.) were administered for further 28 days. The treatment efficacy was measured by measuring serum lipid profile, fasting insulin level, sex hormones level, ovarian steroidogenic enzymes, ovarian tissue insulin receptor, AMPK, and GLUT4 protein expression levels, and histomorphological studies. The post-treatment effect was confirmed by reproductive performance studies. Results Letrozole-induced PCOS rats showed significant estrus irregularity, abnormal sex hormones levels, and hyperandrogenism indicated by showing increased free androgenic index and decreased sex hormones binding globulin (SHBG) level. The insulin resistance in PCOS rats was indicated by increased fasting glucose levels with impaired glucose clearance in the OGT test. Homeostasis Model Assessment Index of Insulin Resistance (HOMA-IR) increased level, also decreases INSR, GLUT4, and AMPK mRNA expression in ovarian cells confirming the insulin resistance in PCOS rats. Ovarian histology in PCOS rats also showed many follicular cysts, atretic follicles, and the absence of corpus luteum. The administration of polyherbal syrup, in a dose-dependent manner, effectively restored these alterations. The treatment of polyherbal formulation 400 mg/kg possesses highly significant efficacy over the treatment of metformin in PCOS rats. It mainly acts by reducing peripheral and ovarian hyperandrogenism and improves insulin sensitivity via activating the insulin receptor and AMP-activated kinase-mediated transcription and translation of GLUT4 from the cytoplasm to the ovarian membrane improves glucose uptake and promotes the follicular development and ovulation. The higher fertility rate, delivery index, and survival of delivered pups confirm the broader and superior efficacy of PCOS. These beneficial actions are mainly attributable to the formulation's inclusion of the key secondary metabolites flavonoids and phytosterols. In conclusion, the prepared polyherbal syrup was found to be the safest and most effective alternative medicine for both endocrinal and metabolic complications of PCOS women.

Pergularia daemia hydro-ethanolic extract protects against pentylenetetrazole kindling-induced seizures, oxidative stress, and neuroinflammation in mice. JOURNAL OF ETHNOPHARMACOLOGY 2021; 279:114338. [PMID: 34144196 DOI: 10.1016/j.jep.2021.114338] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 04/12/2021] [Accepted: 06/12/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Current antiepileptic drugs fail to control approximately 30% of epilepsies. Therefore, there is a need to develop more effective antiepileptic drugs, and medicinal plants provide an attractive source for new compounds. Pergularia daemia (Asclepiadaceae) is used in Cameroon traditional medicine to treat stroke, anemia, inflammation, and epilepsy. Recently, traditional healers claim that an hydro-ethanolic extract of the roots of P. daemia is more effective than an aqueous extract on refractory seizures. AIM OF THE STUDY The antiepileptic effect of P. daemia hydro-ethanolic extract was investigated on the pentylenetetrazole kindling model of temporal lobe epilepsy in mice and possible mechanisms of action. MATERIALS AND METHODS Mice were divided into 8 groups treated as follows: normal group received distilled water (10 ml/kg, p.o.), control group received distilled water (10 ml/kg, p.o.), ethanol group received ethanol (5%, p.o.), positive control received sodium valproate (300 mg/kg, p.o.), and test groups received P. daemia hydro-ethanolic (HE) extract (1.6, 4, 8 and 16 mg/kg, p.o.). All groups were kindled by 11 injections of pentylenetetrazole (PTZ) (35 mg/kg, i.p.), once every alternate day (48 ± 2 h), until the development of kindling, i.e., the occurrence of stage 5 seizures for two consecutive trials. One week later, i.e., 29th day, mice were challenged with a single and lower dose of PTZ (25 mg/kg, i.p.) that does not induce seizures in normal mice but causes seizures in mice prone to seizures and behavioral alterations. After completion of the kindling procedure, Morris water maze, passive avoidance, and open field tests were performed. Afterward, animals were euthanized, and hippocampi were removed for the estimation of the levels of GABA-transaminase (GABA-T), L-glutamate decarboxylase (L-GAD), and γ-aminobutyric acid (GABA). Oxidative stress and neuroinflammation markers also were quantified. Finally, histological analysis of the hippocampus was carried out. RESULTS PTZ-kindling induced myoclonic jerks and generalized tonic-clonic seizures in control mice. However, the HE extract of P. daemia (4-16 mg/kg), compared to sodium valproate, significantly protected mice against myoclonic jerks and generalized tonic-clonic seizures. Also, the HE extract (1.6-16 mg/kg) significantly increased the seizure score. Furthermore, the HE extract of P. daemia significantly reduced seizure-induced cognitive impairments. PTZ-kindling induced significant alterations in GABA, GABA-T, and L-GAD contents as well as oxidative stress, and neuroinflammation, and the HE extract significantly reversed these effects, suggesting possible mechanisms. All these activities of the HE extract were confirmed by its protective effect against neuronal loss in the hippocampus. CONCLUSIONS The HE extract of P. daemia protected mice against kindled seizures and cognitive impairments, and these effects were greater than those of sodium valproate, a widely used antiepileptic drug. These effects may be mediated by neuromodulatory, anti-oxidant, and anti-inflammatory activities, thus suggesting a neuroprotective effect. These findings help to explain the beneficial use of these HE extracts of P.daemia in traditional medicine to treat epilepsy in Cameroon.

Abstract
Background
Medicinal plants play a significant role in the progress of persuasive therapeutic agents. Earlier to the innovation of synthetic drugs, human beings completely relied on the plants for the treatment of various ailments. Natural product extracts, particularly those derived from different plant species, provided the main source of Siddha, Ayurveda and Folk medicines. P. daemia is a perennial climber, traditionally reported for the treatment in a variety of diseases. In present review, we focused on the present status of phytochemical and pharmacological activities P. daemia.
Methodology
With the support of electronic databases such as Science Direct, Google Scholar, Mendeley, Scirus and PubMed central. Traditional knowledge information collected by Indian taxonomical books, survey from local rural and tribal peoples. Pharmacological data’s obtained from scientific journals published from 2000 to 2020.
Results
P. daemia extract, contains several phytochemicals, especially rich in flavonoids. These secondary metabolites synthesized from P. daemia have been reported for the treatment of various chronic diseases. In recent years, P. daemia phytoconstituents set as a key role in natural drug development as it harbours many in vitro and in vivo pharmacological activities such as anti-inflammatory, anti-cancer, anti-fertility, anti-arthritic and antimicrobial etc.,
Conclusion
P. daemia was the less studied plant compared to other medicinal plants. In this context more emphasis has to be laid on studies that discuss on the secondary metabolite activities and molecular mechanisms that work against various chronic diseases.

Abstract
Diabetes mellitus is one of the major health problems in the world, the incidence and associated mortality are increasing. Inadequate regulation of the blood sugar imposes serious consequences for health. Conventional antidiabetic drugs are effective, however, also with unavoidable side effects. On the other hand, medicinal plants may act as an alternative source of antidiabetic agents. Examples of medicinal plants with antidiabetic potential are described, with focuses on preclinical and clinical studies. The beneficial potential of each plant matrix is given by the combined and concerted action of their profile of biologically active compounds.

Wound healing and anti-inflammatory activities induced by a Plantago australis hydroethanolic extract standardized in verbascoside. JOURNAL OF ETHNOPHARMACOLOGY 2018; 225:178-188. [PMID: 30009976 DOI: 10.1016/j.jep.2018.07.012] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Revised: 07/09/2018] [Accepted: 07/10/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plantago australis is a popular plant found to be widely spread in Latin America. In folk medicine, the seeds and leaves are used mainly for anti-inflammatory, wound healing, among others. The verbascoside, a phenolic glycoside, is an active chemical component described in this species of plant, which has antioxidant, anti-inflammatory and healing effects. PURPOSE The aim of the present study was to evaluate whether P. australis hydroethanolic extract (PAHE) standardized in verbascoside could promote wound healing associated with anti-inflammatory action within both in vitro and in vivo models. METHODS For the wound healing activity, we used a Scratch Test, an assay capable of evaluating the migratory ability of keratinocyte cells (HaCat) in vitro and thereby confirming the activity in rats. For the anti-inflammatory activity, the inflammation was induced with LPS in microglial murine cells (N9). Inflammatory mediators (IL-6, IL-10, IL-12p70, INFγ, MCP-1 and TNFα) were measured and the activity of superoxide dismutase (SOD), catalase (CAT), and mitochondrial membrane potential were evaluated. In addition, using paw edema induced by carrageenan in rats, the anti-inflammatory activity in vivo was analyzed. RESULTS The PAHE and verbascoside, induced a significant increase in migration of keratinocytes, at all concentrations tested when compared to the negative control. The wound healing activity in vivo showed that the PAHE accelerated the process. The treatments with PAHE and verbascoside induce increases in the antioxidants enzymes, suggesting a possible activation of these enzymes. However, this did not result in an increase in the expression of inflammatory mediators in microglial cells. In LPS activated cells the verbascoside displayed a significant reduction of TNFα, IL-6, IL-12p70, MCP-1 and INFγ, while the PAHE only displayed statistically significant reduction in TNFα. Interestingly, both the compounds could reduce the oxidative parameters in N9 cells activated by LPS. Additionally, pretreatment with PAHE inhibited the paw edema in rats. CONCLUSION The results suggest that PAHE has wound healing activity, improving cells migration and, as well as was able to reverse the oxidation effect in LPS-activated N9 cells. The wound-healing and anti-inflammatory activities of PAHE were confirmed in vivo. In addition, the presence of verbascoside can be related to PAHE effects, since this compound was capable of increase keratinocytes migration and inhibiting inflammation mediators.

Abstract
In this study, we investigated antiepileptogenic and neuroprotective effects of the aqueous extract of Pergularia daemia roots (PDR) using in vivo and in vitro experimental models. In in vivo studies, status epilepticus caused by pilocarpine injection triggers epileptogenesis which evolves during about 1–2 weeks. After 2 h of status epilepticus, mice were treated during the epileptogenesis period for 7 days with sodium valproate and vitamin C (standards which demonstrated to alter epileptogenesis), or Pergularia daemia. The animals were then, 1 week after status epilepticus, challenged with acute pentylenetetrazole (PTZ) administration to test behaviorally the susceptibility to a convulsant agent of animals treated or not with the plan extract. Memory was assessed after PTZ administration in the elevated plus maze and T-maze paradigms at 24 and 48 h. Antioxidant and acetylcholinesterase activities were determined in the hippocampus after sacrifice, in vitro studies were conducted using embryonic rat primary cortical cultures exposed to L-glutamate. Cell survival rate was measured and apoptotic and necrotic cell death determined. The results showed that chronic oral administration of PDR significantly and dose-dependently increased the latency to myoclonic jerks, clonic seizures and generalized tonic–clonic seizures, and the seizure score. In addition, PDR at all doses (from 4.9 to 49 mg/kg) significantly decreased the initial and retention transfer latencies in the elevated plus maze. Interestingly PDR at the same doses significantly increased the time spent and the number of entries in T-maze novel arm. PDR significantly increased the activities of acetylcholinesterase and antioxidant enzymes superoxide dismutase, catalase, and total glutathione and proteins, and decreased malondialdehyde level. Furthermore, PDR increased viability rate of primary cortical neurons after L-glutamate-induced excitotoxicity, in a dose dependent manner. Altogether these results suggest that PDR has antiepileptogenic and neuroprotective effects, which could be mediated by antioxidant and antiapoptotic activities.

Abstract
BACKGROUND The leaves of Pergularia daemia Forsk (family Asclepidaceae) provide alternative plant-based treatments for the management of diabetes mellitus and diarrhoea in both humans and indigenous poultry species like the Guinea fowls (Numida meleagris). However, no scientific investigations to validate its usefulness in Ghana have been established. This study therefore sought to investigate the anti-hyperglycaemic activity of the 70 % ethanolic extract of P. daemia using streptozotocin (STZ)-induced diabetic male Sprague-Dawley rats. Additionally, the antioxidant and antimicrobial properties of the extract were investigated. METHODS The total phenolic content, total flavonoids content, radical scavenging activity and reducing power assays were estimated using Folin-Ciocalteu method, aluminium chloride colorimetric assay, Fe3+ reduction assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays, respectively. RESULTS The results showed that P. daemia extract caused anti-hyperglycaemic activity in the STZ-induced rats at doses of 30, 60 and 90 mg/kg body weight with significant reduction in blood glucose levels. The phytosterols, saponins, phenols, alkaloids, tannins and triterpenes found in the extract may be responsible for the observed anti-hyperglycaemia and antioxidant activities. The extract also showed antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. CONCLUSIONS These findings justify the folkloric use of P. daemia as an anti-diabetic and antibacterial agents for susceptible species.

Abstract
PURPOSE Pergularia daemia Forsk. (Asclepiadaceae) is a traditionally reported medicinal herb used to treat joint pain and arthritis. However, there are no scientific reports about anti-arthritic activity of P. daemia methanolic extract on rats as animal model. This study identifies bioactive compounds present in the P. daemia methanolic extract and evaluates its anti-arthritic potential in CFA induced arthritic rats. METHODS AND RESULTS Phytoconstituents of P. daemia extract were examined using LC-ESI/MS method. Anti-arthritic activity of P. daemia extract was determined by various biochemical experiments (RF, ESR and CRP), ultrasonography and histological analysis. LC-ESI/MS analysis resulted in the identification of major flavonoids compounds such as formononetin, qurecetin, chrysoeriol, taxifolin and naringenin. Serum biomarker analysis, after the treatment with PDME (500mg/kg b.w.) revealed that the hemoglobin (11.84±0.42g/dL) and RBC (8.38±0.67million/mm(3)) levels were significantly increased whereas WBC (8.91±0.38thousands/mm(3)), RF (17.94±0.45IU/mL), ESR (7.91±0.12mm/h) and CRP (22.56±0.26mg/L) levels were decreased when compared with the CFA induced arthritic control group. Histology results revealed that treatment with PDME has resulted in significant prevention against bony destruction by decreasing soft tissue swelling and narrowing of joint spaces (250 and 500mg/kg b.w.). CONCLUSION Anti-arthritic effect of P. daemia might be due to the presence of these bioactive flavonoids. These findings lend pharmacological support to the reported folkloric use of P. daemia in the treatment and management of painful, arthritic inflammatory conditions.
