The present study was undertaken to scientifically validate the antidiabetic activity of aqueous fruit extract of Trichosanthes dioica Roxb. (Family: Cucurbitaceae) which has been traditionally used for managing diabetes mellitus. This plant commonly known as "Sespadula" in English has not been explored scientifically so far for its glycemic potential except by our research group. The study was conducted with variable doses on normal, mild, and severe diabetics models, and several biochemical parameters including blood glucose level (BGL) were assessed. Maximum fall in BGL of 23.8% in normal rats and of 31.3% in mild diabetic rats was observed during their fasting blood glucose (FBG) and glucose tolerance test (GTT) with the dose of 1000 mg kg(-1). In severely diabetic animals after 4 weeks treatment with FBG, postprandial glucose, total cholesterol, and triglyceride levels were reduced by 28.7, 30.7, 57.2, and 18.5%, whereas high density lipoprotein, total protein, hemoglobin, and body weight were increased by 33.0, 36.7, 15.7 and 16.7%, respectively. Moreover, urine sugar was reduced from +4 to +1. Thus, the study scientifically validates the traditional use of T. diocia in diabetes management and could be developed as an effective oral agent for treating diabetes mellitus and complications associated with it.
本研究旨在科学验证栝楼(Trichosanthes dioica Roxb.,葫芦科)果实水提取物的抗糖尿病活性,该提取物在传统医学中一直用于治疗糖尿病。这种植物在英文中通常被称为“Sespadula”,到目前为止,除了我们的研究小组外,尚未对其血糖调节潜力进行科学探索。本研究对正常、轻度和重度糖尿病模型使用不同剂量进行,评估了包括血糖水平(BGL)在内的多个生化参数。在空腹血糖(FBG)和葡萄糖耐量试验(GTT)中,1000 mg kg(-1)剂量组使正常大鼠的BGL最大降幅达23.8%,轻度糖尿病大鼠的BGL最大降幅达31.3%。在重度糖尿病动物中,经过4周治疗后,FBG、餐后血糖、总胆固醇和甘油三酯水平分别降低了28.7%、30.7%、57.2%和18.5%,而高密度脂蛋白、总蛋白、血红蛋白和体重分别增加了33.0%、36.7%、15.7%和16.7%。此外,尿糖从+4降至+1。因此,本研究科学验证了栝楼在糖尿病治疗中的传统用途,有望开发成为一种治疗糖尿病及其相关并发症的有效口服药物。
