ABSTRACT
Objective: To establish the fingerprint of Danshen Glucose Injection by HPLC. Methods: Separation was performed on an Alltima C18(4.6mm?250mm,5?m) analytical column, with mobile phase consisting of 1 %acetic-water and 1 %acetic acid-methanol and with gradient elute at the flow rate of 1mL/min-1. The UV detection was set at 281nm. Results: Six peaks of Danshen Glucose Injection wre indicated, and the chief ingredients were determined by HPLC. Conclusion: This method is accurate and with good reproducibility and can be used for the quality control of Danshen Glucose Injection.
ABSTRACT
AIM: Two models of experimental myocardial ischemia were set up to observe the protection of Danshen glucose injection against ischemia in rats. METHODS: Models of experimental acute myocardial ischemia were made by ligature or medication (pituitrin) to check the indices of ECG, hemodynamics, and morphology. RESULTS: A dosage of Danshen glucose injection 4.0 g/kg, 8.0 g/kg was given to rats by intravenous injection; the rats had undergone a thirty-minute ligatute of coronary left anterior descending branch, and used as a model of ischemic reperfusion. The observations showed that Danshen glucose injection exerted a recovery effect on heart rate, blood pressure, internal pressure of left ventricule and its peak/trough rate (?dp/dt max ), and ST segment (electrocardiogram). The injection markedly reduced the myocardial infarct size of the coronary-ligatured rats. The injection benefited the rats with pituitrin (iv) induced acute myocardial ischemia to reverse and T-wave fall. CONCLUSION: Danshen glucose injection has a protective and therapeutic action on the experimental myocardial ischemia of rats.
ABSTRACT
Objective: To establish the determination for 5 HMF in Glucose Injection containing the extract of Radix Salviae Miltiorrhizae. Methods: Using HPLC with Hypersil ODS [4.6mm(i.d)?250mm] column, methanol 0.5% acetic acid as a mobile phase and detection wavelength at 284nm. Results: The peak of 5 hydroxymethylfurfural was separated from the peak of Danshensu. Conclusion: The method is simple, sensitive and accurate with a good reproducibility and can be used as the quality control for Glucose Injection containing the extract of Radix Salviae Miltiorrhizae.
