Method for judging color of panax notoginseng saponins solution

The invention provides a method for judging the color of a panax notoginseng saponins solution. The method comprises the following steps: s1, acquiring the spectral transmittance of a liquid to be detected and a standard colorimetric solution under each wavelength in a visible light wave band; s2, converting the spectral transmittance obtained in the step s1 into a color space parameter; s3, establishing a parameter threshold value of each standard color number and a color space parameter range of the standard color number based on the color space parameters of the standard colorimetric solution obtained in the step s2; s4, comparing the color space parameter, obtained in the step s2, of the to-be-detected liquid with the color space parameter range, established in the step s3, of the standard color number, and determining the color system and the color number of the to-be-detected liquid; the color judgment result of the panax notoginseng saponins solution obtained by the method disclosed by the invention is
