The present study was undertaken to evaluate the anti-ulcer and antioxidant activities of the ethanol extract of Lagenaria breviflora (EELB) whole fruit in laboratory rats.
The anti-ulcer property of the ethanolic extract of the whole fruit of Lagenaria breviflora (LB) was assessed using the cold-restraint stress-induced (CRU) gastric ulcer, pyloric ligation-induced (PL) gastric ulcer, aspirin-induced (ASP) gastric ulcer and alcohol-induced (AL) gastric ulcer models. The scavenging activity of the LB extract was examined with 1, 1-diphenyl-2-picryl-hydrazyl (DPPH), Nitric oxide, Hydroxyl radical and Superoxide anion scavenging models.
EELB (50, 100, 150 and 200 mg/kg, b.w.) protected against the CRU gastric ulcer dose dependently. Similarly, 150 mg/kg b.w. of the LB extract protected against the PL gastric ulcer, ASP gastric ulcer and AL gastric ulcer and was comparable to omeprazole (10 mg/kg b.w.) or Suscralfate (500 mg/kg b.w.), respectively. The in vitro antioxidant activity of LB was demonstrated by its ability to quench free radicals generated by nitric oxide and superoxide anion with a concomitant scavenging potential against DPPH-induced radical formation.
Taken together, the study showed that the whole fruit extract possess potent anti-ulcer and antioxidant activities.
本研究旨在评估短花葫芦(Lagenaria breviflora)全果乙醇提取物(EELB)在实验大鼠中的抗溃疡和抗氧化活性。
采用冷束缚应激诱导(CRU)胃溃疡、幽门结扎诱导(PL)胃溃疡、阿司匹林诱导(ASP)胃溃疡和酒精诱导(AL)胃溃疡模型,评估短花葫芦全果乙醇提取物(LB)的抗溃疡特性。用1,1-二苯基-2-苦基肼(DPPH)、一氧化氮、羟自由基和超氧阴离子清除模型检测LB提取物的清除活性。
EELB(50、100、150和200mg/kg,体重)对CRU胃溃疡具有剂量依赖性保护作用。同样,150mg/kg体重的LB提取物对PL胃溃疡、ASP胃溃疡和AL胃溃疡具有保护作用,分别与奥美拉唑(10mg/kg体重)或硫糖铝(500mg/kg体重)相当。LB的体外抗氧化活性表现为能够淬灭一氧化氮和超氧阴离子产生的自由基,并同时清除DPPH诱导的自由基形成。
综上所述,该研究表明短花葫芦全果提取物具有强大的抗溃疡和抗氧化活性。
