Using Natural Products Application Solution with UNIFI for the Comparison of the Chemical Ingredients of Shuanghuanglian Oral Drink from Two Different Manufacturers

Significance of the Topic

Traditional Chinese Medicine products vary depending on raw material origin, cultivation, harvest time and processing methods. Establishing a systematic, scientific approach to compare chemical profiles is essential for ensuring authenticity, consistent quality control and development of robust product standards.

Objectives and Study Overview

This study demonstrates the application of the Natural Products Application Solution with UNIFI for binary comparison of Shuanghuanglian oral drinks produced by two manufacturers. The goal is to rapidly identify common, differing and unique chemical ingredients to support product quality assessment and guide further research and development.

Methodology

Samples were diluted tenfold and analyzed by UPLC coupled to Xevo G2-S QTof MS using MSE acquisition in both positive and negative ion modes. Data processing in the UNIFI platform employed five preset binary comparison workflows to perform peak picking, library matching against a Traditional Medicine Library, structural elucidation of fragment ions and automated report generation.

Instrumentation Used

• ACQUITY UPLC I-Class System with FTN Sample Manager and HSS T3 column (2.1 x 100 mm, 1.8 µm)
• Xevo G2-S QTof MS operated in ESI+ and ESI– modes with low/high collision energy MSE acquisition
• UNIFI Scientific Information System with integrated Traditional Medicine Library and structural elucidation tools

Main Results and Discussion

Binary comparison revealed that forsythiaside A, forsythiaside B, dextrorotary hydroxyl forsythiaside A, arctin and rutin were more abundant in manufacturer 1, whereas baicalin levels were higher in manufacturer 2. Mirror plots and component summary charts provided clear visualization of shared, differing and unique features. Unmatched signals suggest opportunities for further identification using UNIFI’s MassFragment and external libraries.

Benefits and Practical Applications

• Automated workflows streamline data acquisition, processing and reporting, reducing analysis time and operator expertise requirements
• High-resolution UPLC separation combined with accurate-mass QTof MS enables comprehensive profiling of complex herbal formulations
• Predefined binary comparison and report templates support consistent evaluation of raw materials, batches, manufacturers and processing variables

Future Trends and Applications

Advances in high-throughput separation, enhanced informatics and machine learning–driven pattern recognition will expand the scope of binary comparison to larger natural product libraries. Real-time monitoring and regulatory compliance workflows will further integrate these methods into industrial quality control and research applications.

Conclusion

The Natural Products Application Solution with UNIFI delivers an effective, automated platform for comparing detailed chemical profiles of traditional medicine products. This approach enhances reliability in quality control and supports the development of standardized benchmarks for herbal formulations.
