Study on Stability of Salvianolate Lyophilized Injection and Establishment of Stability-Indicating Analysis Method
To study the degradation of salvianolate lyophilized injection (SLI) and establish a stability-indicating analysis method.
Method:
2
UPLC-Q-TOF-MS/MS was used to conduct a qualitative study on the main components of SLI
and a stability-indicating analysis method was established for simultaneous determination of the original components of SLI and its degradation products. The stability of SLI were systematically assessed under physicochemical conditions of high temperature
oxidation
metal ions.
Result:
2
Totally 13 main active ingredients in SLI were identified
and a semi-quantitative analysis was performed. Under the conditions of high temperature
oxidation
light
trivalent ion and divalent ion
6
4
3
4 and 1 new degradation products were added respectively. The established stability-indicating analysis method can simultaneously determine the degradation products of the main components and their active components in SLI
with a good separation effect.
Conclusion:
2
According to the degradation mechanism of the main ingredients in SLI
macromolecular polyphenol acid compounds are degraded into small molecular compounds
such as tanshinol and protocatechu aldehyde by a series of reactions
like benzofuran open-loop
hydrolysis of ester bond and removal of DSS. The stability-indicating analysis method can be used for the stability quality control of traditional Chinese medicine Salvianolate Lyophilized Injection (SLI).
