Abstract
A method for extracting and identifying a polysaccharide from a complex sample. The method includes: subjecting a complex sample to be treated to sterilization and enzyme deactivation to obtain a system, and subjecting the system to solid-liquid separation to obtain a sterilization and enzyme deactivation-treated solution; deproteinizing the sterilization and enzyme deactivation-treated solution to obtain a deproteinized solution; purifying the deproteinized solution by using a hydrophilic lipophilic balance-solid phase extraction (HLB-SPE) cartridge to obtain a purified solution; subjecting the purified solution to alcohol precipitation to obtain the polysaccharide; and subjecting the polysaccharide to methylation, glycoside residue derivatization and liquid chromatography-mass spectrometry (LC-MS) analysis in sequence.
