Scope
The main technical content: Using the liquid-liquid extraction method to extract DP from water, with dichloromethane as the extraction solvent. After the extraction solution is concentrated, it is purified using a multi-layer silica gel column. The target compounds are detected by gas chromatography-mass spectrometry. They are qualitatively identified based on the retention time, fragment ions, mass-to-charge ratio, and abundance ratio of the target compounds in the sample. They are quantitatively determined using the internal standard method.
