摘要
目的系统研究以松树皮为原料提取原花青素的方法及工艺条件。方法采用超声波法,用水作为提取剂,从料液比、提取温度、提取时间、提取次数四个方面进行比较。在这些单因素试验的基础上,对超声处理条件进行正交试验。同时进行回流与索氏提取,与超声提取进行比较。结果影响原花青素得率的因素是:料液比>提取时间>提取温度>提取次数;超声提取>索氏提取>回流提取。结论超声波提取法的适宜提取条件为:料液比为1∶14,温度为50℃,提取时间为40 min,提取次数为2次,原花青素的得率最高。
Objective To investigate the method and technological conditions for extraction of procyanidin from Pine Bark. Methods Using ultrasonic extraction method, with water as extraction agent, we compared the solid-liquid ratio, extraction temperature, extraction time and extraction times. Based on the single factor test, or- thogonal test was used for ultrasonic processing conditions. At the same time, reflux extraction and Soxhlet extrac- tion were compared with ultrasonic extraction. Results The influence factors of yield rate of procyanidin were as follows： solid-liquid ratio 〉 extraction time 〉 extraction temperature 〉 extraction times; ultrasonic extraction 〉 Soxhlet extraction 〉 reflux extraction. Conclusion The optimum conditions were as follows ： the solid-liquid ratio was 1： 14, extraction temperature was at 50℃, extracted for 40min and each for 2 times.
