Sample pre-treatment method for detecting sesaminol triglucoside in sesame and detection method

The invention discloses a sample pre-treatment method for detecting sesaminol triglucoside in sesame. The method includes the detailed steps that an ethanol solution of 60-80% is added into crushed sesame samples according to the material-liquid ratio of 1 g:40-60 ml, then the weight of the mixture is m through weighing, then subjected to ultrasonic treatment for 10-20 minutes at 30-50 DEG C, cooled to indoor temperature and weighed again, an ethanol solution of 60-80% is used for supplementing the mixture to m, even shaking and standing are performed, and supernate is filtered and loaded into a sample injection bottle to be detected. The invention further provides a detection method using the pre-treatment method. According to the method, the step of degreasing is omitted, the solution is directly adopted for extraction, in this way, operation is easy and convenient, the cost is low, and stability is good. The detection method utilizing a high-performance liquid chromatograph is accurate and reliable and suitable for determining the content of sesaminol triglucoside in the sesame.
