- 摘要:
- 为提取西瓜皮中的有效成分,更好的利用西瓜资源,采用HD-8型阳离子交换树脂从西瓜皮中分离L瓜氨酸,用HZ-820型树脂对洗脱液进行脱色,探索了L-瓜氨酸的有效提取方法和提取工艺参数以及工艺条件的控制。结果表明:HD-8型阳离子交换树脂对L-瓜氨酸有良好的吸附效果,最大交换容量为23.125 mg?g-1树脂;以0.25 mol?L-1?NH4OH作为洗脱液,洗脱载荷L-瓜氨酸的HD-8树脂20 min,洗脱率达到了89.6%,洗脱效果约为同浓度下NaOH的3.5倍;HZ-803、HZ-820、D303三种吸附树脂脱色效果中,HZ-820为最优。
- Abstract:
- In order to better use of watermelon resource and extracte the effective components in watermelon rind,the extraction method of L-citrulline was explored by controlling the process parameters and conditions.The type HD-8 cation exchange resin was used to isolate L-citrulline from watermelon rind and then the eluent was decolorized by the type HZ-820 resin.The results showed that the typeHD-8 cation exchange resin was highefficiency with the largest exchange capacity of 23.125 mg L-citrulline per gram resin.The elution rate reached 89.6% when the typeHD-8 resin loading L-citrulline was eluted by 0.25 mol?L-1 NH4OH for 20 min which was 3.5 times higher than using NaOH at the same concentration as eluent.Type HZ-820 adsorbent resin had optimal decolorizing efficiency compared with type HZ-803 and type D303.
