Example Embodiment
[0027] Example 1 Gas Chromatographic Detection of Danshu Capsule
[0028] Sample preparation method: Take 0.72g of the contents of Danshu Capsule, place it in a test tube with stopper, add 10ml of absolute ethanol, fully shake or ultrasound and then stand for 20min, filter, and take the filtrate to get it;
[0029] Contrast chromatographic conditions: initial temperature 60℃, keep for 4min, 2℃·min -1 Increase the temperature to 100℃ at a rate of 100℃·min -1 The rate of heating is 230℃, the temperature of the injection port is 250℃, the FID detector, the detector temperature is 250℃, the injection volume is 1.0μl, the split ratio is 10:1, carrier gas: N2, flow rate 20ml*min -1 .
[0030] Prepare the sample solution according to the above method and perform gas chromatography test. The test results are as follows figure 1 As shown, there are 13 chromatographic peaks detected, and the retention times are 0.60min, 0.76min, 1.10min, 3.44min, 4.40min, 5.08min, 5.59min, 7.63min, 8.05min, 9.3...
