Embodiment 1
[0008] Determination according to high performance liquid chromatography (Appendix VID of Chinese Pharmacopoeia 2005 edition).
[0009] Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel was used as filler; methanol-water (70:30) was used as mobile phase; detection wavelength was 250nm. The number of theoretical plates should not be less than 2000 based on the peak of schisandrin A.
[0010] Take about 10 mg of Schizandrin A reference substance, accurately weigh it, put it in a 50ml measuring bottle, add an appropriate amount of methanol, dissolve it by ultrasonic (40KHZ power 120W), and dilute to the mark with methanol. Precisely draw 3.0, 4.0, 5.0, 6.0, 7.0ml of the above solutions into 10ml measuring bottles respectively, dilute to the mark with methanol, shake well, and make standard solutions of serial concentrations. Inject 20 μl of samples respectively and record the chromatograms. The results are shown in Table 1.

Embodiment 2
[0017] Determination according to high performance liquid chromatography (Appendix VID of Chinese Pharmacopoeia 2005 edition).
[0018] Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel was used as filler; methanol-water (70:30) was used as mobile phase; detection wavelength was 250nm. The number of theoretical plates should not be less than 2000 based on the peak of schisandrin A.
[0019] Take the Schizandrin A reference substance solution with a concentration of 100 μg / ml, and measure it at 0, 2, 4, 6, and 8 hours under the above-mentioned chromatographic conditions, and the results are shown in Table 2.

[0021] Placement time (h)
[0022] The results showed that the test solution was stable within 8 hours.
Embodiment 3
[0024] Determination according to high performance liquid chromatography (Appendix VID of Chinese Pharmacopoeia 2005 edition).
[0025] Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel was used as filler; methanol-water (70:30) was used as mobile phase; detection wavelength was 250nm. The number of theoretical plates should not be less than 2000 based on the peak of schisandrin A.
[0026] Preparation of reference substance solution: Take an appropriate amount of Schisandrin A reference substance, accurately weigh it, add methanol to make a solution containing 100 μg per 1 ml, and obtain it.
[0027] The preparation of need testing solution: get the Schisandrin A reference substance that takes by prescription ratio and accurately weigh a certain amount and mix with adjuvant, take appropriate amount, accurately weigh, put in 10ml measuring bottle, add methanol appropriate amount, ultrasonic treatment (frequency 40KHZ, power 120W) for 20...
