Biological activity and hydroxy safflor yellow A content of intermediates in preparation of Safflower Injection
(2.Modern Research Center for Traditional Chinese Medicine, Taiyuan, China 030006)
【Abstract】In order to investigate the effect of various production processes on the quality of Safflower Injection, the biological activities of the intermediates were evaluated by measuring activated partial thromboplastin time (APTT) and adenosine diphosphate (ADP) induced platelet aggregation in vitro. Intermediates were produced by key processes, such as extraction, concentration, twice alcohol precipitation, water sedimentation and two sterilizations during the production of Safflower Injection. The content of main chemical components in intermediates was determined by HPLC. The results showed that with the advance of the preparation process of Safflower Injection, the inhibition of ADP-induced platelet aggregation rate of each intermediate decreased gradually, and the trend of extending APTT activity decreased first and then increased. Meanwhile, the content of hydroxy safflor yellow A (HSYA) was gradually lowered, the content of p-hydroxy-cinnamic acid was increased, and new chemical component p-hydroxybenzaldehyde was produced. In conclusion, sterilization played a key role in the biological activity and HSYA content of Safflower injection.
