Abstract:

The quality of polysaccharides from different regions was studied by using multiple fingerprint analysis and chemometric analysis. Polysaccharides from 10 batches of Glehnia littoralis were compared based on Fourier-transform infrared spectroscopy (FT-IR), high-performance liquid chromatography (HPLC), gel permeation chromatography (GPC), and proton nuclear magnetic resonance (1H-NMR). According to the results, the 10 batches of polysaccharides from G littoralis had high similarity by analyzing HPLC, FT-IR, 1H-NMR, and GPC fingerprints.
