Scope

The main technical content is as follows: The extraction is carried out by shaking with a mixed solvent of acetonitrile and water. The samples are derivatized by two derivatizing reagents, namely methoxamine hydrochloride and N,O-bis(trimethylsilyl)trifluoroacetamide. Then, the samples are directly detected by a gas chromatograph with a hydrogen flame detector. Phenyl-β-D-pyranoside glucoside is used as the internal standard, and quantitative analysis is carried out using the internal standard standard curve method.
