Different parts of the Parkia biglobosa plant are employed in traditional medicine in different African communities. However, information ratifying its use and biochemical influence on health is still scanty in literature. Thus, the present study assessed the influence of the ethyl acetate fraction of Parkia biglobosa leaves (EAFPB) on some biochemical parameters of sub-chronic fructose-loaded rats. Twenty-five Wistar rats were randomized into five groups (n = 5). The normal control group was maintained on normal diet only while the high fructose solution (HFS) control (placebo), reference and treatment groups received high fructose solution (3 g/kg/d b.w of fructose) for 30 days before treatment. Based on pilot study, two doses (100 and 200 mg/kg/d b.w) of EAFPB were selected and were administered to two groups of test animals while the reference group received 300 mg/kg/d b.w. of metformin for 14 days. Thereafter, blood was collected from fasted animals for biochemical analyses for the examination of level of glycated hemoglobin (HbA1c), liver status (alanine and aspartate aminotransferases (ALT and AST) and alkaline phosphatase (ALP) activities, and bilirubin level), lipid profile (total cholesterol, triglyceride, and low- and high-density lipoproteins levels) and lipid peroxidation (malondialdehyde – MDA level). EAFPB was shown to have a good DPPH radical scavenging activity (EC50 = 0.395 mg/ml). Chromatographic analysis of EAFPB revealed 28 known flavonoids (mainly kaempferol (21.31 mg/100 g), quercetin (12.84 mg/100 g), and luteolin (6.75 mg/100 g)), four hydrocinnamic acids derivatives (mainly P-coumaric acid (6.73 mg/100 g)), and 11 phenolic acids derivatives (mainly chlorogenic acid (48.18 mg/100 g) and protocatechuic acid (21.58 mg/100 g)). Relative to normal control, it was observed that fructose overload significantly increased serum activities of ALP, ALT, and AST, and levels of MDA, total cholesterol, low density lipoprotein and triglyceride in placebo. However, EAFPB significantly tapered the elevated serum activities of ALP, ALT, and AST. In addition, relative to placebo, the increased levels of HbA1c, MDA, and lipid health markers were also rebated by EAFPB. Ethyl acetate fraction of Parkia biglobosa leaves attenuates biochemical aberrations in fructose-loaded rats, an effect attributable to the rich store of polyphenolic compounds in the fraction.

Parkia biglobosa植物的不同部分在不同的非洲社区被用于传统医学。但是,在文献中仍缺乏批准其使用和生化影响健康的信息。因此,本研究评估了Parkia biglobosa叶片(EAFPB)的乙酸乙酯组分对亚慢性果糖负荷大鼠某些生化参数的影响。将25只Wistar大鼠随机分为5组(n = 5)。正常对照组仅维持正常饮食,而高果糖溶液(HFS)对照(安慰剂),参考组和治疗组在治疗前30天接受高果糖溶液(3 g / kg / d bw的果糖)。根据先导研究,两种剂量(100和200 mg / kg / d b。w)选择EAPFB并给予两组试验动物,而参考组接受300mg / kg / d bw的二甲双胍治疗14天。之后,从禁食的动物中收集血液进行生化分析,以检查糖化血红蛋白(HbA1c)的水平,肝脏状况(丙氨酸和天冬氨酸转氨酶(ALT和AST)和碱性磷酸酶(ALP)的活性以及胆红素的水平),脂质状况(总胆固醇,甘油三酸酯和低密度脂蛋白和高密度脂蛋白的含量)和脂质过氧化(丙二醛– MDA含量)。EAFPB被证明具有良好的DPPH自由基清除活性(EC50 = 0.395 mg / ml)。EAFPB的色谱分析显示了28种已知的类黄酮(主要是山ka酚(21.31 mg / 100 g),槲皮素(12.84 mg / 100 g)和木犀草素(6.75 mg / 100 g)),4种氢肉桂酸衍生物(主要是对香豆酸(6.73 mg / 100 g))和11种酚酸衍生物(主要是绿原酸(48.18 mg / 100 g)和原儿茶酸(21.58 mg / 100 g))。相对于正常对照,观察到果糖超负荷显着增加了安慰剂中ALP,ALT和AST的血清活性以及MDA,总胆固醇,低密度脂蛋白和甘油三酸酯的水平。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。73 mg / 100 g))和11种酚酸衍生物(主要是绿原酸(48.18 mg / 100 g)和原儿茶酸(21.58 mg / 100 g))。相对于正常对照,观察到果糖超负荷显着增加了安慰剂中ALP,ALT和AST的血清活性以及MDA,总胆固醇,低密度脂蛋白和甘油三酸酯的水平。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。73 mg / 100 g))和11种酚酸衍生物(主要是绿原酸(48.18 mg / 100 g)和原儿茶酸(21.58 mg / 100 g))。相对于正常对照,观察到果糖超负荷显着增加了安慰剂中ALP,ALT和AST的血清活性以及MDA,总胆固醇,低密度脂蛋白和甘油三酸酯的水平。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。18 mg / 100 g)和原儿茶酸(21.58 mg / 100 g)。相对于正常对照,观察到果糖超负荷显着增加了安慰剂中ALP,ALT和AST的血清活性,以及​​MDA,总胆固醇,低密度脂蛋白和甘油三酸酯的水平。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。18 mg / 100 g)和原儿茶酸(21.58 mg / 100 g)。相对于正常对照,观察到果糖超负荷显着增加了安慰剂中ALP,ALT和AST的血清活性,以及​​MDA,总胆固醇,低密度脂蛋白和甘油三酸酯的水平。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。安慰剂中的总胆固醇,低密度脂蛋白和甘油三酸酯。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。安慰剂中的总胆固醇,低密度脂蛋白和甘油三酸酯。但是,EAPFB明显降低了ALP,ALT和AST升高的血清活性。此外,相对于安慰剂,EAFPB还抑制了HbA1c,MDA和脂质健康标志物水平的升高。Parkia biglobosa叶片的乙酸乙酯级分减弱了果糖加载大鼠的生化畸变,这归因于级分中多酚化合物的丰富储存。
