Summary: | The invention discloses a pseudo-ginseng exogenous pollutant detection method, which comprises: taking three-year-old pseudo-ginseng dry main roots, crushing, screening with a 40 mesh sieve to obtain a sample, weighing 0.5 g of the sample, adding a certain amount of a quintozene standard liquid, placing in a centrifuge tube, adding 40 mL of petroleum ether, sequentially carrying out vibration extraction and centrifugation, and carrying out gradient elution to obtain the pseudo-ginseng exogenous pollutant. Adding the centrifuged supernate into a concentration bottle through anhydrous sodium sulfate to obtain an extracting solution I, repeatedly oscillating and extracting, centrifuging once, combining the two extracting solutions II, carrying out rotary evaporation on the extracting solution II in a water bath to obtain a concentrated solution, washing the concentrated solution for at least three times by using petroleum ether to obtain a washing solution, and drying to obtain a finished product. And carrying o |
