3 Principle

The crushed or shredded sample is subjected to Soxhlet extraction or ultrasonic-assisted extraction with acetone-n-hexane. The volumetric solution was diluted with methanol-water solution, and determined by high performance liquid chromatography-tandem mass spectrometry, and quantified by external standard method.
