The invention discloses a method for establishing
andrographis paniculata
quality control by using a QAMS (quantitative analysis of multi-components by single marker) method. Comprising the following steps: preparing a
test sample solution, preparing a reference solution, determining chromatographic conditions and
mass spectrum conditions, determining main components of a
test sample, establishing a
standard curve, performing methodological investigation by using an external standard method, determining an internal reference and a
relative correction factor of the quantitative analysis of multi-components by single marker, and investigating the durability of the
relative correction factor and positioning of a chromatographic peak. And comparing and verifying the content of the measured sample. The invention further discloses an
andrographis paniculata
quality control method. According to the method,
relative correction factors of an internal reference substance and other to-be-detected components are established on the basis of an ultra-
high performance liquid chromatography-
tandem mass spectrometry-based quantitative analysis of multi-components by single marker, and the contents of four components including desoxidized
andrographolide,
andrographolide, dehydroandrographolide and
andrographolide in
andrographis paniculata are determined as a
quality control method of the
andrographis paniculata medicinal material, so that the quality of the
andrographis paniculata medicinal material is improved. The calculated value and the measured value meet the requirements of
quantitative methodology, the requirements of reference substances are reduced, and the quality
control level of
andrographis paniculata is improved.
