Study on the Characteristic Graph and Quality Correlation of Banlangen Injection
Objective:To establish a method for detecting the content of uridine,guanosine,(R,S)-goitrin,and adenosine in Banlangen injection and to study their fingerprints.High performance liquid chromatography was used,with Eclipse Plus C18 column(4.6 mm×250 mm,5 μm)Detection wavelength:250 nm,using methanol(A)-water(B)as the mobile phase,gradient elution(0～3 min,95% B;3～20 min,95% B～90% B;20～40 min,90% B-30% B;40-42 min,30% B～95% B;42～50 min,95% B),flow rate:1.0 mL/min,column temperature chamber:30℃,injection volume:10 μL.The experimental operation is simple,fast,and the results are accurate.It is suitable for the determination of uridine,guanosine,(R,S)-goitrin e,and adenosine content in Banlangen injection,and the establishment of a fingerprint for the quality evaluation of Banlangen injection.
