Determination of Substances with High Molecular Weight in Porcine Anterior Pituitary and Adrenal Cortex Extracts Injection / 中国药师

ABSTRACT

Objective:To determinate the substances with high molecular weight in porcine anterior pituitary and adrenal cortex extracts injection. Methods:The HPLC analysis was performed on a TSK-GEL G2000SWXL(7. 8 mm × 300 mm,5 μm) column with the mobile phase of trifluoroacetic acid-acetonitrile-water(0. 05:35:65). The flow rate was 0. 5 ml·min-1, and the detection wave-length was 214 nm. Results:The substances with high molecular weight in porcine anterior pituitary and adrenal cortex extracts injec-tion was below 1%. Conclusion:The method is simple and repeatable, which can be used for the control of the substances with high molecular weight in porcine anterior pituitary and adrenal cortex extracts injection.
