Analysis of Medicinal Excipients for Herbal Medicines

Medicinal excipients are the basic materials and essential components of herbal preparations. It gives the drug a certain dosage form and has a great relationship with improving the efficacy and reducing the adverse effects of herbal medicines. The quality of medicinal excipients has an important impact on the safety and efficacy of the preparations. As an important component of herbal medicines, the safety of medicinal excipients cannot be ignored. To ensure that you are the first to know about the safety of medicinal excipients, Lifeasible offers analytical services for the separation and testing of solvents, co-solvents, emulsifiers, defoamers, diluents, protein protectors, and other herbal medicinal excipients.

Separation assays

The detection of pharmaceutical excipients often requires the separation of complex samples, and isocratic elution is not sufficient for the separation of most pharmaceutical excipients. The refractive index detector (RI) can detect compounds with weak or no UV absorption. We also offer an evaporative light scattering detector (ELSD) to compensate for the lack of RI, and can be used for gradient elution with significantly improved sensitivity. The ELSD performs particularly well in the detection of difficult, volatile compounds. In addition to the ELSD, the UV-Vis detector is highly sensitive. It has a wide linear range, which can be used to some extent for the quantitative analysis of pharmaceutical excipients.

Technical advantages

• Can be used in conjunction with other detection techniques for more comprehensive analysis, ensuring that all components in the sample are detected.
• Precise temperature control of the atomization, evaporation, and detection phases improves separation while maintaining low diffusivity and providing reproducible results.
• Transmission of a signal to the LC system to stop the flow rate when low air pressure is detected.

In addition to their role as excipients, carriers, and stability enhancers, pharmaceutical excipients have essential functions such as solubilization, solubilization aid, and slow and controlled release. They are important ingredients that may affect the quality, safety, and efficacy of herbal preparations. Lifeasible is committed to developing more and better methods for the testing of pharmaceutical excipients to make your work and research easier; please feel free to contact us for information.
