Effects of Storage Condition on Quality of Semen Armeniacae Amarum / 中药新药与临床药理

ABSTRACT

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 content,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.
