In China, traditional Chinese medicines (TCMs) have been used in clinical applications for thousands of years. The successful hyphenation of high-Performance liquid chromatography (HPLC) and mass spectrometry (MS) has been applied widely in TCMs and biological samples analysis. Undoubtedly, HPLC/MS technique has facilitated the understanding of the treatment mechanism of TCMs. We reviewed more ...

Manual fingerprint classification algorithms are very time consuming, and usually not accurate. Fast and accurate fingerprint classification is essential to each AFIS (Automatic Fingerprint Identification System). This paper investigates a fingerprint classification algorithm that reduces the complexity and costs associated with the fingerprint identification procedure. A new structural algorit...

This Application Note describes the development of conventional HPLC and Rapid Resolution LC (RRLC) methods for the analysis of Buplerui (Chaihu). A comparison of fingerprint chromatograms of different Buplerui samples showed different peak profiles of different TCMs collected from different places. The method for the Agilent 1200 Series Evaporative Light Scattering Detector (ELSD) was optimize...

High-performance liquid chromatography (HPLC) fingerprinting is a reliable quality control method for traditional Chinese medicine (TCM). As research combining fingerprint and pharmacodynamics of TCM, the TCM spectral effect relationship widely used in its preparations, which can better reflect intrinsic great significance on material basis efficacy. In this study, an HPLC extracts from aerial ...
