摘要
杏仁中所含的苦杏仁苷具有一定的生物毒性,从林产品安全的角度,采用HPLC定量分析方法对3个仁用杏品种杏仁中的苦杏仁苷质量分数进行了检测,旨在为仁用杏杏仁的食用安全性评价提供科学依据。结果表明,以纯甲醇作为提取溶剂,按照1∶20的料(脱脂粉末)液比,80℃水浴回流提取1.5h,为仁用杏杏仁中苦杏仁苷提取的最优化方法;采用HPLC法测得3个仁用杏品种木瓜杏、龙王帽、薄壳1号杏仁中苦杏仁苷质量分数分别为0.138%,0.154%和0.123%;测得的对照(中药材苦杏仁)中苦杏仁苷质量分数为2.269%。
Amygdalin in kernel-using apricot cuhivars has bio-toxicity to some extent. For the security of forest products and standard indices of security to eat of the 3 kernel-using apricot cultivars, the contents of amygdalin in the kernels were tested by the method of HPLC （High Performance Liquid Chromatographic）. It was proved that the optimal condition for extracting amygdalin from apricot kernels was using methanol as flux, fine powder （apricot kernel without fat） and liquid in a proportion of 1 to 20 and extracted for 1.5 h with hot water of 80 ℃. Results showed that amygdalin content in Muguaxing cultivar was about 0.138%,in Longwangmao cuhivar about 0.154%, and in Boke 1 cultivar about 0.123%, while the content in the bitter apricot kernel （traditional Chinese medicine） was 2.269%.
