Salvia miltiorrhiza stem leaf quality control method

The invention discloses a salvia miltiorrhiza stem leaf quality control method. The salvia miltiorrhiza stem leaf quality control method includes the steps: A, appearance identification of fresh stem leaves; B, identification: drying the fresh salvia miltiorrhiza stem leaves, smashing the dried salvia miltiorrhiza stem leaves to obtain a powder salvia miltiorrhiza stem leaves sample, concentrating after ethanol extraction, inspecting under an ultraviolet lamp after thin-layer chromatography development, and comparing with a standard product to identify the sample; C, measurement of moisture content and ash content: measuring moisture content and ash content of the dried salvia miltiorrhiza stem leaves; D, extract determination: soaking the salvia miltiorrhiza stem leaves according to a cold soaking method to obtain water-soluble extracts, and measuring content of the water-soluble extracts; E, active ingredient determination: extracting the dried salvia miltiorrhiza stem leaves, and measuring content of active ingredients in extracts; F, comparison: comparing measurement results with quality standards to analytically judge whether the sample meets quality requirements or not. By the salvia miltiorrhiza stem leaf quality control method, the problem of lack of systematic product quality control standards of salvia miltiorrhiza stem leaves at the present is solved, and stability and uniformity of medicinal material quality can be guaranteed.
