Abstract
Purslane (P), chard (CHA), and chicory (CHI) leaf extracts are individually and traditionally used in the treatment of diabetes mellitus. Polyphenols, flavonoids, the polyphenolic profile of the extracts, and their antioxidant activity were determined. This study evaluated the antidiabetic activity of combinations of these extracts in streptozotocin-induced diabetic rats. Diabetic groups were administered orally and daily for 40 days with the investigated extracts at 250 mg/kg body weight (b.w.) or metformin (100 mg/kg b.w.) as a drug. Fasting blood glucose, oral glucose tolerance, insulin, and fructosamine were assessed. The combined extracts with high levels of P or CHI exerted potent hypoglycemic activity compared with metformin in addition to the restoration of the histopathological changes in the liver and pancreas of diabetic rats to a near-normal state. Therefore, these combined extracts could be developed as natural drugs for diabetes.

Abstract
Rubus species holds promise as a valuable source of polyphenols and bioactive compounds, offering significant potential as functional food ingredients with both nutraceutical and pharmaceutical benefits. However, many edible species within this genus remain under-explored and their importance is largely unrecognized. This review aims to provide an overview of the nutritional and bioactive components of both explored and under-explored Rubus species, highlighting their potential health advantages, value addition, and recent advancements. The economic exploitation of Rubus is currently limited to a few cultivated species, while numerous non-conventional and wild edible species are overlooked. Recognizing the economic and nutritional significance of exploited Rubus species, it is imperative to explore the untapped potential of these underutilized plants. By doing so, these species can be preserved from endangerment and contribute to nutritional and livelihood security for communities having access to them. This review emphasizes the importance of understanding the exceptional characteristics of Rubus species as "superfoods" and encourages the promotion and cultivation of these unexplored species. By expanding the cultivation and utilization of under-explored Rubus species, we can unlock their full potential and support sustainable nutritional and economic benefits.

(Lamiaceae) Leaves in Mice. J Exp Pharmacol 2023; 15:255-266. [PMID: 37304205 PMCID: PMC10257431 DOI: 10.2147/jep.s409997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Accepted: 06/01/2023] [Indexed: 06/13/2023] Open
Abstract
Background Globally, the prevalence of diabetes mellitus is rising. Due to the scarcity, high cost, and many adverse effects of modern treatments, traditional medicine is commonly used in rural areas to treat a variety of illnesses, including diabetes mellitus. The aim of this study was to assess the antihyperglycemic and hypoglycemic effects of Ocimum lamiifolium Hochst ex Benth leaves. Methods A crude methanol 80% extract's and its solvent fractions' effects on healthy, oral glucose-given, and STZ-induced diabetic mice were examined. Swiss albino mice of either sex were assigned into sixteen groups, each containing six mice, for the OGTT and hypoglycemia tests. Male mice were used in the study, and they were divided into groups for the negative control (citrate buffer for diabetic mice), the normal control (Tween 2%), the test groups, and a positive control (glibenclamide) for the antihyperglycemic test in STZ (200 mg/kg body weight)-induced diabetic mice. Results A crude 80% methanol extract of 200 mg/kg effectively lowered blood glucose levels (p <0.05) and none of the fractions extracts caused hypoglycemia shock in norma mice. The aqueous residue at 100, 200, and 400 mg/kg, the n-butanol fraction at 100 and 200 mg/kg, and the chloroform fraction at 200 mg/kg demonstrated higher glucose tolerance in orally glucose-loaded mice (p <0.05). The crude 400 mg/kg of an 80% methanol extract, 100 and 200 mg/kg of the n-butanol fraction, 200 and 400 mg/kg of the chloroform fraction, and 5 mg/kg of glibenclamide significantly reduced blood glucose levels in STZ-induced diabetic mice (p <0.05). Conclusion The current research demonstrates that a crude 80% methanol extract of Ocimum lamiifolium Hochst ex Benth leaves, as well as its solvent fractions, significantly reduce blood sugar levels in mice that are healthy, loaded with glucose, and streptozotocin induced diabetic mice.

J Exp Pharmacol 2022; 14:59-72. [PMID: 35177940 PMCID: PMC8845113 DOI: 10.2147/jep.s343735] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Accepted: 01/14/2022] [Indexed: 12/25/2022] Open
Abstract
Background Despite modern therapeutic armamentaria, DM remains a 21st-century public health menace. Novel phytomedicines are a rapidly expanding focus of research. The juice of Dorstenia barnimiana roots has long been used for the treatment of diabetes mellitus in traditional Ethiopian medicine, but its efficacy has not been supported by in vitro or in vivo scientific study. To investigate this, the present work was performed. Methods In this experimental study, simple random sampling was applied. Healthy male mice were used in normoglycemic and oral glucose-tolerance test (OGTT) models. Streptozotocin (IP, 150 mg/kg)–administered diabetic male mice were utilized. Animals were randomly divided into five groups of six each. Group I received 10 mL/kg distilled water, groups II–IV received 100 (DB100), 200 (DB200), and 400 (DB400) mg/kg crude extract, respectively, and group V received glibenclamide 5 mg/kg. A sham group (group VI) was added that received 10 mL/kg distilled water. All treatments were given orally. FBG, serum-lipid profiles, and body-weight changes were then measured. In vitro α-amylase inhibitory activity was also evaluated. Results The doses were atoxic up to 2,000 mg/kg. There was α-amylase inhibition activity of 67.52% at 500 μg/mL with an IC50 of 4.595 μg/mL. The OGTT revealed an antihyperglycemic effect of the crude extract. This was not attributed to a hypoglycemic side effect. In the diabetic mouse model, it shrank FBG levels remarkably. There were also significant reductions in serum TC, TGs, VLDL-C, and LDL-C. Nevertheless, HDL-C and body-weight levels returned. Conclusion The present study confirmed the safety and promising in vivo antidiabetic and antidyslipidemic activity of D. barnimiana, thus corroborating the traditional claim.

The Glycemic Control Potential of Some Amaranthaceae Plants, with Particular Reference to In Vivo Antidiabetic Potential of Agathophora alopecuroides. Molecules 2022; 27:molecules27030973. [PMID: 35164238 PMCID: PMC8839903 DOI: 10.3390/molecules27030973] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 01/18/2022] [Accepted: 01/20/2022] [Indexed: 11/16/2022] Open
Abstract
Natural products continue to provide inspiring moieties for the treatment of various diseases. In this regard, investigation of wild plants, which have not been previously explored, is a promising strategy for reaching medicinally useful drugs. The present study aims to investigate the antidiabetic potential of nine Amaranthaceae plants: Agathophora alopecuroides, Anabasis lachnantha, Atriplex leucoclada, Cornulaca aucheri, Halothamnus bottae, Halothamnus iraqensis, Salicornia persia, Salsola arabica, and Salsola villosa, growing in the Qassim area, the Kingdom of Saudi Arabia. The antidiabetic activity of the hydroalcoholic extracts was assessed using in vitro testing of α-glucosidase and α-amylase inhibitory effects. Among the nine tested extracts, A. alopecuroides extract (AAE) displayed potent inhibitory activity against α-glucosidase enzyme with IC50 117.9 µg/mL noting better activity than Acarbose (IC50 191.4 µg/mL). Furthermore, AAE displayed the highest α- amylase inhibitory activity among the nine tested extracts, with IC50 90.9 µg/mL. Based upon in vitro testing results, the antidiabetic activity of the two doses (100 and 200 mg/kg) of AAE was studied in normoglycemic and streptozotocin (STZ)-induced diabetic mice. The effects of the extract on body weight, food and water intakes, random blood glucose level (RBGL), fasting blood glucose level (FBGL), insulin, total cholesterol, and triglycerides levels were investigated. Results indicated that oral administration of the two doses of AAE showed a significant dose-dependent increase (p < 0.05) in the body weight and serum insulin level, as well as a significant decrease in food and water intake, RBGL, FBGL, total cholesterol, and triglyceride levels, in STZ-induced diabetic mice, compared with the diabetic control group. Meanwhile, no significant differences of both extract doses were observed in normoglycemic mice when compared with normal control animals. This study revealed a promising antidiabetic activity of the wild plant A. alopecuroides.
