马齿苋、车前草复合保健饮料的研制及其抗氧化作用研究

以马齿苋、车前草为主要原料，添加柠檬酸、蔗糖、蜂蜜等辅料，经过筛选配方和优化工艺，研制了马齿苋、车前草复合保健饮料；并采用化学模拟体系测定了该饮料抑制脂质体过氧化及清除·OH、O2·和DPPH·的能力。结果表明：主辅料用量均对该饮品的质量有较大影响，最佳配方为1000ml 饮料中含干马齿苋6.67g、干车前草 8.33g、白砂糖60g、蜂蜜12g、柠檬酸1.4g。马齿苋、车前草复合保健饮料对自由基的清除能力较强，其清除·OH、O2·、DPPH·和抑制脂质体过氧化的IC50 分别为96.2、201、4.76 和15.34mg/L(以总黄酮计) 。

Study on Development and Antioxidant Effects of Compound Health Beverage Made from Portulaca oleracea L. and Plantago depressa Willd.

Using the extracts of Portulaca oleracea L. and Plantago depressa Willd. as raw materials and adding some complements such as citric acid, sucrose and honey, a kind of compound health beverage was developed. The results showed that he concentrations of Portulaca oleracea L., Plantago depressa Willd. and citric acid have great effects on the quality of the beverage, and the optimum formula is as follows: 6.67 g of dry Portulaca oleracea L., 8.33 g of dry Plantago depressa Willd., 60 g of sucrose, 1.4 g of citric acid and 12 g of honey per 1000 ml beverage. Furthermore, the chemical simulation indicated that the compound healthy beverage has effective activity on scavenging·OH, O2· and DPPH·and its IC50 of inhibiting lipid peroxidation is 96.2, 201, 4.76 and 15.34 mg/L (total flavonoids), respectively.
