Determination method of total 2-(2-phenethyl) chromone compound content

The invention relates to a determination method of a total 2-(2-phenethyl) chromone compound content, comprising the following steps of: extracting and filtering an agilawood sample to obtain a solution to be determined; by taking 6, 7-dimethoxy-2(2-phenethyl) chromone as a reference substance, dissolving the solution to be determined with a same solvent, preparing standard solutions with different concentrations, determining a light absorption value under 230nm, and establishing a standard curve; and determining the light absorption value under 230nm after the solution to be determined is diluted, the total 2-(2-phenethyl) chromone compound content in the solution to be determined is calculated by the standard curve and a dilution multiple, and finally calculating the total 2-(2-phenethyl) chromone compound content in the agilawood sample. According to the determination method disclosed by the invention, operation is convenient; and by utilizing the characteristics that a 2-(2-phenethyl) chromone compound has a 2-(2-phenethyl) chromone mother nucleus and determining the total 2-(2-phenethyl) chromone compound content in an agilawood substance by adopting an ultraviolet spectrophotometric method, pertinence is strong, stability is good, accuracy is high, and repeatability is good.
