Embodiment 1
[0046] 1. Instruments and reagents
[0047] Instrument: Agilent7890A gas phase-Agilent7000B triple quadrupole mass spectrometer (Agilent Technologies, Inc., USA)
[0048] Test medicine: Longhu Rendan botanical medicine
[0049] Other reagents: ethyl acetate, butyl acetate, isopropanol, chloroform.
[0050] 2. Method
[0051] (1) Prepare the test solution: take Longhu Rendan herbal medicinal solvent to prepare a 0.5-5mg / ml test solution;
[0052] Preparation of the reference substance solution: Accurately weigh an appropriate amount of the reference substance, place it in a 10mL volumetric flask, dissolve it with a solvent and dilute to the mark. Shake well to obtain the stock solution of each reference substance, and store in a refrigerator at 4°C.
[0053] Precisely measure the appropriate amount of each stock solution and dilute with ethyl acetate to obtain a mixed standard solution of each reference substance. Add 10-20 μL of internal standard naphthalene to the mixed ...
