摘  要:
本研究通过四步反相高压液相色谱从Lactobacillushelveticus和Lactobacilluscaseisubsp.casei制作的酸乳中分离到对ACE活性具有较强抑制作用并具有较强降高血压效果的活性肽VPP和IPP。它们抑制ACE活性的IC50分别为8.89和5.17mol/L;给高血压老鼠灌胃试验结果显示,VPP在0.90、1.80、3.60mg/kg体重/天剂量下,其最大降血压值分别为12.3±3.7、17.9±4.2和25.3±4.3mmHg,呈极显著性差异(p<0.01),IPP在0.60、1.20、1.80mg/kg体重/天剂量下,其最大降血压值分别为16.8±3.4、25.5±4.6和29.1±3.5mmHg,呈极显著性差异(p<0.01)。

摘  要:
Peptides of VPP and IPP with potent inhibitory activity on angiotensin I-converting enzyme (ACE) and hypertensive function were purified from the sour milk fermented with Lactobacillus helveticus JCM 1004 and Lactobacillus casei subsp. Casei ATCC393 by using four-step reverse-phase HPLC.The concentrations of VPP and IPP providing 50% inhibition of ACE (IC50) were 8.89 and 5.17 M,respectively.The most effective values of 12.3±3.7、17.9±4.2、25.3±4.3 and 16.8±3.4、25. 5±4.6、29.1±3.5 mmHg of decreasing systolic blood pressure (SBP) of spontaneously hypertensive rats after gastric intubation of VPP at the dosages of 0.90、1.80、3.60 mg/kg of body weight/day or IPP at the dosages of 0.60、1.20、1.80 mg/kg of body weight/day were obtained, respectively. Outstanding significance in the differences was showed in above results.
