摘要[目的]研究大豆皂苷与异黄酮对小鼠血脂的影响,为从食疗方面调节血脂的研究提供依据。[方法]将72只(7周大小)健康昆明小鼠随机分成6组,分别为基础组、高脂饲料组、高脂饲料+大豆皂苷低剂量组(25 mg/(kg·d))、高脂饲料+大豆皂苷高劑量组(50 mg/(kg·d))、高脂饲料+大豆异黄酮低剂量组(50 mg/(kg·d))、高脂饲料+大豆异黄酮高剂量组(100 mg/(kg·d))。连续灌胃4周后,眼球取血,测定血清的甘油三酯、总胆固醇、低密度脂蛋白和高密度脂蛋白水平。[结果]与基础组比较,高脂组小鼠的血清甘油三酯、总胆固醇水平和低密度脂蛋白水平都显著升高(P<0.05),高密度脂蛋白水平显著下降(P<0.05)。与高脂组比较,大豆异黄酮高、低剂量组的总胆固醇和低密度脂蛋白的水平都显著降低(P<0.05),高密度脂蛋白的水平都显著上升(P<0.05)。大豆皂苷低剂量组的总胆固醇和甘油三酯水平显著低于高脂组(P<0.05),高密度脂蛋白的水平显著升高(P<0.05),高剂量组的大豆皂苷的甘油三酯水平显著下降。[结论]大豆皂苷和大豆异黄酮对调节小鼠血脂都有一定的效果,对高脂血症都有一定的预防作用。

Abstract [Objective] The effects of soybean saponin and soybean isoflavone on blood lipids in mice were studied to provide the experimental basis for adjusting the blood lipid from the aspect of diet. [Method] 72 Kunming mice(seven weeks old) were divided into six groups randomly, which was base group, highfat group, high fat+ low soybean saponin group (25 mg/(kg·d)), high fat + high soybean saponin group (50 mg/(kg·d)), high fat + low soybean isoflavone group 50 mg/(kg·d)), and high fat +high soybean isoflavone group ( 100 mg/(kg·d)). They were gavaged for 4 weeks, then the eyes were removed to obtain the blood. The total cholesterol, triglyceride and low density lipoprotein and high density lipoprotein of mouse serum were determined. [Result] The level of total cholesterol, triglyceride, and low density lipoprotein in highfat group was higher than that of the base group(P<0.05), but the level of high density lipoprotein in highfat group was lower than that of the base group(P<0.05). Compared with the highfat group, the level of the total cholesterol, and low density lipoprotein was decreased in soybean isoflavone of low and high dose group(P<0.05), but the level of high density lipoprotein was increased(P<0.05). The level of total cholesterol and triglyceride in low soybean saponin group was reduced(P<0.05), but the level of high density lipoprotein was increased(P<0.05).The level of triglyceride in high soybean saponin group was reduced.[Conclusion] Soybean isoflavone and soybean saponin had effects on reducing blood fat and preventing hyperlipidemia.

近年来,高血脂的发生率逐年升高。通过对陕西省5 320例体检者的血脂情况分析,发现有1 138例患有高血脂,发病率为21.4%[1]。高血脂是冠心病、动脉粥样硬化等心血管疾病的危险因素。据统计,欧洲每年因心血管疾病造成180万人过早死亡;我国心血管疾病患者约2.3亿,每天因心血管疾病死亡9 590人,占总死亡原因的41%,居死亡原因第一位[2]。目前,高血脂的治疗主要以患病后药物为主,但长期食用化学药物会对肝脏等造成一定的损伤,因此开发具有调节血脂功效的天然食品显得越来越重要。……
