Ficus glumosa, commonly known as the fig tree or "African rock fig" is a plant with immense medicinal value used for the management of diabetes for over 2000 years. The aim of the present study is to determine the hypoglycemic and anti-lipidemic properties of the ethanolic leaves extract of Ficus glumosa in alloxan-induced diabetic Wistar rats. Thirty (30) adult male Wister rats weighing (120 - 220) grams of about 18 to 22 weeks of age were used in the study. The animals were assigned into six groups (1-6) of five rats (n=5) each. Group VI served as the positive control group receiving 0.9% normal saline (5ml/kg) alone via intra-peritoneal route (i.p.), Groups I (negative control), II, III, IV and V were treated with alloxan and after the induction of hyperglycaemia, received in addition via i.p. for 7 days: 0.9% normal saline (5ml/kg) alone, 100mg/kg, 200mg/kg and 400mg/kg of ethanolic leaves extract of Ficus glumosa respectively while Group V received 6lU/kg of short-acting insulin. The determinations of blood glucose levels were carried out at intervals of one day for 7 days. Serum lipid profile, were done on the 7th day.Premininary phytochemical screening revealed the presence of flavonoids,saponin,tannins,cardiac glycosides,triterpenes,ceramides and reducing sugars.The LD50 of the extract of Ficus glumosa was found to be 2,154mg/kg.The results of the study showed that,100mg/kg and 400mg/kg of ethanolic leaves extract of Ficus glumosa significantly lowered blood glucose levels and 200mg/kg significantly lowered serum lipid profile compared with negative control group.In conclusion, the results of the study showed that Ficus glumosa possesses anti-hyperglycaemic and anti-lipidemic effect.
聚果榕,通常被称为无花果或“非洲岩榕”,是一种具有巨大药用价值的植物,在治疗糖尿病方面已有2000多年的历史。本研究的目的是确定聚果榕乙醇叶提取物对四氧嘧啶诱导的糖尿病Wistar大鼠的降血糖和抗血脂特性。本研究使用了30只18至22周龄、体重(120 - 220)克的成年雄性Wistar大鼠。将动物分为六组(1 - 6组),每组五只大鼠(n = 5)。第六组作为阳性对照组,仅通过腹腔注射途径(i.p.)接受0.9%生理盐水(5ml/kg);第一组(阴性对照组)、第二组、第三组、第四组和第五组用四氧嘧啶处理,在诱导高血糖后,也通过腹腔注射途径连续7天接受以下处理:第一组仅接受0.9%生理盐水(5ml/kg),第二组、第三组、第四组分别接受100mg/kg、200mg/kg和400mg/kg的聚果榕乙醇叶提取物,而第五组接受6lU/kg的短效胰岛素。连续7天每天间隔测定血糖水平。在第7天测定血清脂质谱。初步植物化学筛选显示存在黄酮类化合物、皂苷、单宁、强心苷、三萜、神经酰胺和还原糖。聚果榕提取物的半数致死量(LD50)为2154mg/kg。研究结果表明,与阴性对照组相比,100mg/kg和400mg/kg的聚果榕乙醇叶提取物显著降低血糖水平,200mg/kg显著降低血清脂质谱。总之,研究结果表明聚果榕具有抗高血糖和抗血脂作用。
