Method for detecting content of flavonoid compounds in herba desmodii styracifolii extract

The invention provides a method for detecting the content of flavonoid compounds in a desmodium styracifolium extract, the flavonoid compounds are selected from vicenin-2, vicenin-1, schaftoside, neoschaftoside, isovitexin and vicenin-3, and the method comprises the following steps: carrying out liquid chromatography detection on the desmodium styracifolium extract, the content of vicenin-2, the content of vicenin-1, the content of schaftoside, the content of neoschaftoside, the content of isovitexin and the content of vicenin-3 are determined on the basis of the detection result; wherein a mobile phase adopted in the liquid chromatography detection comprises a mobile phase A and a mobile phase B, and the mobile phase A is selected from a trifluoroacetic acid aqueous solution and methanol; the mobile phase B is selected from methanol. By utilizing the method disclosed by the invention, the contents of vicenin-2, vicenin-1, schaftoside, neoschaftoside, isovitexin and vicenin-3 in the desmodium styracifolium ex
