Example Embodiment

[0040] Example 1

[0041] Take the antiviral oral liquid produced by Guangzhou Xiangxue Pharmaceutical Co., Ltd. with the batch number 20051201 and the production date on December 7, 2005, and test it on December 8, 2005 according to the following conditions:

[0042] A. Chromatographic conditions: the chromatographic column is an elastic quartz capillary column, the temperature of the injection port is 230°C, the temperature of the detector is 250°C, split injection, the temperature is programmed to rise from 70°C to 230°C, the temperature is kept at 230°C for 10 to 15 minutes, and the flow rate is 1ml / min.

[0043] B. The preparation steps of the reference substance solution are as follows:

[0044] Accurately weigh the patchouli alcohol reference substance, add n-hexane to dissolve and make a 0.5 mg / ml solution.

[0045] C. Preparation of the test solution:

[0046] Take 50ml of antiviral oral solution, add 50ml of chloroform, and extract under reflux for 2 hours, take ...
