High performance gel permeation chromatography (HPGPC), ultraviolet-visible spectra (UV), infrared absorption spectra (IR) and ion chromatography (IC) techniques were used in fingerprint analysis of tea polysaccharides (TPS). Multi-fingerprint was applied to assess TPS consistency and to discriminate other polysaccharides in order to achieve the quality control of TPS. The experimental data for spectrogram and chromatogram were used for similarity calculation, included angle cosine method and… CONTINUE READING
