Argyrolobium roseum is described in texts for its botanical aspects with no mention of its therapeutic uses. Recently, a solvent fraction of this plant has been reported to possess insulin secretagogue activity.
Primary objective of the study was to evaluate the hypoglycemic activity of different fractions of Argyrolobium roseum plant. Secondary objective was to devise a model for detecting its beta-cell neogenesis activity.
Alcoholic fraction (AR) was studied in fasting, glucose-loaded and streptozotocin (STZ)-treated hyperglycemic rats. For deducing beta-cell neogenesis activity, a sub-lethal dose of STZ, causing delayed death in the animals, was administered.
AR in a dose of 200 mg/kg showed hypoglycemic activity in fasting and STZ-treated rats. With sub-lethal dose of STZ, recovery from hyperglycemia was seen.
AR of Argyrolobium roseum possesses hypoglycemic and a possible beta-cell neogenesis activity. Further studies are required to confirm its beta-cell neogenesis potential by cytological methods and to establish its role in the treatment of type 2 diabetes.
玫瑰银叶豆在植物学文献中有记载,但未提及其治疗用途。最近,据报道该植物的一种溶剂提取物具有胰岛素促分泌活性。
本研究的主要目的是评估玫瑰银叶豆不同提取物的降血糖活性。次要目的是设计一种检测其β细胞新生活性的模型。
在禁食、葡萄糖负荷及链脲佐菌素(STZ)处理的高血糖大鼠中研究乙醇提取物(AR)。为推断β细胞新生活性,给予亚致死剂量STZ,导致动物延迟死亡。
剂量为200mg/kg的AR在禁食和STZ处理的大鼠中显示出降血糖活性。给予亚致死剂量STZ后,可见高血糖得到恢复。
玫瑰银叶豆的AR具有降血糖及可能的β细胞新生活性。需要进一步研究通过细胞学方法确认其β细胞新生潜能,并确定其在2型糖尿病治疗中的作用。
