摘要
用薄层扫描方法确定了山药中尿囊素的提取条件;用高效液相色谱方法测定了山药中尿囊素的含量,考察了不同产地山药样品中尿囊素含量的差异.该法平均回收率为96.8%,相对标准偏差为4.0%.生长环境、气候等外界条件对山药中尿囊素含量有明显的影响,不同产地山药中尿囊素含量有明显差异.此高效液相色谱法用于山药中尿囊素的含量测定,灵敏度高,重现性好,可供山药质量标准研究参考使用.
The extraction conditions for allantoin in yam were selected by TLC. The amount of allantoin in yam was determined by HPLC with the average recovery of 96.8%, RSD 4.1%. The contents of allantoin in variety of species were remarkably different. The method was found to be suitable and highly sensitive for the determination of allantoin in yam; The environmental conditions, such as growth condition and the climate, affect obviously the allantoin contents in yam.
