摘要: 通过提取方法优选,表明超声法对黑莓果渣中花色苷的提取效果最佳。以60%乙醇为超声法提取溶剂,通过单因素实验分别考察了料液比、超声时间、温度、功率、提取次数对提取黑莓果渣中花色苷的影响。综合单因素实验结果,通过响应面法筛选出最佳的工艺条件为:液料比14:1(mL: g),时间40 min,温度58 ℃,功率300 W,提取2次。通过提取物中花色苷含量与其清除DPPH•活性的相关性分析发现,黑莓果渣提取物清除DPPH•活性与其花色苷含量之间存在相关性,由此推断花色苷为黑莓果渣中主要的自由基清除物质。

Abstract: The anthocyanin in the blackberry pomaces was extracted with the different metheods, and the results showed that the anthocyanin content of rasound-assisted extraction was the highest. The 60% ethanol was used to extract anthocyanin with ultrasonic assisted extraction and ratio of liquid to materia, ultrasoni time, extraction temperature, ultrasonic power, and extraction times were assessed in single-factors experiment. On the basis of single-factor test, the optimum conditions for the ultrasound assisted extraction of anthocyanin from blackberry pomaces were determined as follows using response surface method (RSM): the liquid-olid atio (mL:g) 14:1, extraction time 40 min, extraction temperature 58 ℃, ultrasonic wave power 300 W, and two step extraction. The correlation analysis results showed that the anthocyanin content and DPPH• scavenging activity had significant correlation, and inferenced that anthocyanin was the main free radical scavenging substances.
