中文摘要: 通过单因素试验和正交试验,确定黑枸杞中抗氧化物质的最佳提取工艺条件。结果表明影响提取效果的主 次因素为:提取时间<提取温度<提取剂<料液比;最佳提取工艺条件为:超声提取、料液比 1:25(g/mL)、温度 50 ℃、溶 剂 60 %乙醇、时间 25 min。以维生素 C 作为标准物质,对黑枸杞的总抗氧化性进行评价。采用 pH 示差法测定黑枸杞 中花青素含量。
Abstract:The optimum extract conditions of the main antioxidant in black wolfberry were studied through sin gle factor test and orthogonal test. The results showed that the primary and secondary factors of extraction effect were as follows: extraction time < extraction temperature < concentration of solvent < the ratio for material and liquid. The best extract conditions with ultrasonic extraction were identified that the ratio of solvent to black wolfberry, temperature, extract solvent, and time were 1:25 (g/mL), 50 ℃, 60 % ethanol and 25 min respectively. The antioxidant activity in black wolfberry was evaluated using vitamin C as the standard substance. In addition, the content of anthocyanin in black wolfberry was determined by pH differential method.
