贮存条件对苦杏仁质量的影响

Effects of Storage Condition on Quality of Semen Armeniacae Amarum

目的考察贮存条件对苦杏仁质量的影响。方法采用正交设计法,选取温度、湿度、贮存时间3个因素,每个因素选择3水平,以苦杏仁苷含量、脂肪油含量、酸值、过氧化值为检测指标,优选苦杏仁的最佳贮存条件。脂肪油含量、酸值和过氧化值采用2005版《中国药典》提供的方法测定;苦杏仁苷含量采用HPLC法测定。结果温度是影响苦杏仁苷含量的主要因素,其次是相对湿度和贮存时间。温度也是影响脂肪油含量、酸值的主要因素,其次是相对湿度;对于过氧化值来说,湿度是主要影响因素,其次是温度和贮存时间。结论苦杏仁最佳贮存条件为干燥后2～8℃冷藏,贮存时间越短越好。

Objective To observe the effects of storage condition on the quality of Semen Armeniacae Amarum. Methods Orthogonal design was adopted. The storage condition was optimized with temperature, humidity and storage time as the observation factors, with the content of amygdalin, and the content, acid value and peroxide value of fatty oil as the indexes. The content of fatty oil, acid value and peroxide value were measured according to the methods provided by 2005 edition of Chinese Pharmacopoeia. The content of amygdalin was measured by HPLC. Results Temperature was the main influencing factor of amygdalin eontent, then came humidity and storage time. Temperature was also the main influencing factor of the concent and the acid value of fatty oil, and the humidity was the second. For peroxide value, humidity was the main factor, then came temperature and storage time. Conclusion The optimal conditions of storing Semen Armeniacae Amarum as follows ： storage in dry place with the temperature of 2 - 8℃, and in short storage time.
