Embodiment 1

[0033] A kind of quality control method of platycodon grandiflorum fluid extract comprises the following steps:

[0034] Step 101: Pretreating the platycodon grandiflora liquid extract;

[0035] Step 102: Measure the content W of Platycodon saponin D in the pretreated Platycodon grandiflorum liquid extract by high performance liquid chromatography;

[0036] Step 103: According to the content W of Platycodon grandiflora saponin D, evaluate whether the quality of Platycodon grandiflorum fluid extract is qualified.

[0037] The quality control method of the platycodon root liquid extract of the above-mentioned embodiment realizes the purpose of quantitatively evaluating the quality of the platycodon grandiflorum liquid extract by quantitatively detecting the content of platycodon grandiflorum saponin D. Because the main active ingredient in the platycodon root extract is platycodon saponin D, and its content is relatively large, therefore, the quality of platycodon platycodon ro...

Abstract

The invention relates to the field of medicine quality control and in particular relates to a quality control method of a platycodon grandiflorum fluid extract. The quality control method of the platycodon grandiflorum fluid extract comprises the following steps: step A, pretreating the platycodon grandiflorum fluid extract; step B, measuring the content W of platycodin D in the platycodon grandiflorum fluid extract by adopting a high performance liquid chromatography; step C, evaluating whether the quality of the platycodon grandiflorum fluid extract is qualified according to the content W of the platycodin D. By utilizing the quality control method of the platycodon grandiflorum fluid extract, the purpose of quantitatively evaluating the quality of the platycodon grandiflorum fluid extract is realized by quantitatively detecting the content of the platycodin D. Because the main effective constituent of the platycodon grandiflorum fluid extract is the platycodin D and the content is high, the quality of the platycodon grandiflorum fluid extract can be quantitatively and accurately reflected by quantitatively detecting the content of the platycodin D so as to avoid the problem of uncertainty of quality control.

Description

technical field [0001] The invention relates to the field of medicine quality control, in particular to a quality control method of platycodon grandiflorum liquid extract. Background technique [0002] At present, Platycodon grandiflorum fluid extract is the main component of children's cough syrup, and there is no quantitative quality control point in the quality standard of children's cough syrup, which makes the quality control of children's cough syrup have certain uncertainties. Contents of the invention [0003] The object of the present invention is to provide the quality control method of platycodon grandiflorum fluid extract, to solve above-mentioned problem. [0004] A kind of quality control method of Platycodon grandiflorum liquid extract is provided in the embodiment of the present invention, it comprises the following steps: [0005] Step A: pretreating the Platycodon grandiflora liquid extract; [0006] Step B: Measure the content W of platycodon saponin D...
