Method for performing supercritical extraction on chemical components of ephedra and honey ephedra

The invention relates to a method for performing supercritical extraction on chemical components of ephedra and honey ephedra. The extraction temperature is 45 DEG C; the temperature of an analysis kettle I is 40 DEG C and the pressure is 12 Mpa; the temperature of an analysis kettle II is 40 DEG C and the pressure is 8 Mpa; the time is 2 hours; and the sample is 200 g. The GC condition is a 300m*250um*025um elastic quartz capillary tube column; the initial column temperature is 50 DEG C and then the temperature is increased to 250 DEG C at 4 DEG C/min; the operation time is 50 minutes; He isloaded; the flow is 05 mL/min; and the split ratio is 20:1. The MS condition is that the electronic energy is 70 eV; the scanning range is 40 to 400; the temperature of an ion source is 230 DEG C; andthe interface temperature is 250 DEG C. Volatile oil is extracted from the ephedra and the honey ephedra by a supercritical CO2 extraction technology (SFECO2), separation and authentication are conducted by a gaschromatograph
