Embodiment 1
[0085] This embodiment provides a method for constructing the fingerprint of Notopterygium Shengshi Decoction, including:
[0086] The preparation of the reference solution: take isoimperatorin, dihydro-apebeinol angelate, 5-O-methyl visamidol glycoside, ammonium glycyrrhizinate, liquiritin, ferulic acid, osthole, An appropriate amount of reference substances such as Chuanxiong lactone I, etc., accurately weighed, dissolved in methanol and diluted to make each 1mL containing 4.0 μg of isoimperatorin, 3.5 μg of dihydro-epiperidinol angelate, 5-O-methylvesia A mixed solution of 3.8 μg mitanol glycoside, 3.7 μg ammonium glycyrrhizinate, 3.5 μg liquiritin, 4.0 μg ferulic acid, 4.0 μg osthole, and 0.03 μg ligustilide, shake well to obtain the product.
[0087] Preparation of the test solution: Take about 0.2 g of Qianghuo Shengshi Decoction granules (self-made), weigh it accurately, put it in a stoppered Erlenmeyer flask, accurately add 10 mL of methanol with a volume fraction of 6...
Embodiment 2
[0112] Adopt the method identical with embodiment 1 to prepare need testing solution, then use same chromatographic column, other test conditions are constant, only change flow rate and be 0.7mL / min, 0.9mL / min.
[0113] Such as Figure 10 Shown, the spectrogram of need testing solution in embodiment 1 and the spectrogram of embodiment 2 ( Figure 10 From top to bottom on the right side are the spectra corresponding to flow rates of 0.9mL / min, 0.8mL / min, and 0.7mL / min) for comparison, it can be seen that adjusting the flow rate up and down by 0.1 has no significant impact on the results. It shows that adjusting the flow rate has no obvious effect on the method.
Embodiment 3
[0115] Adopt the same method as in Example 1 to prepare the test solution, then use the same chromatographic column, and keep the other test conditions unchanged, only changing the column temperature to 35°C and 40°C.
[0116] Such as Figure 11 Shown, the spectrogram of need testing solution in embodiment 1 and the spectrogram of embodiment 3 ( Figure 11 From top to bottom on the right side are the spectra corresponding to the column temperature of 40°C, 30°C, and 35°C) for comparison, it can be seen that the adjustment of the column temperature has no obvious influence on the results. It shows that adjusting the column temperature has no obvious effect on the method.
