Method for detecting quality of tendon-relaxing and blood-activating bills

The invention relates to a method for detecting the quality of tendon-relaxing and blood-activating bills. The method comprises the thin layer chromatography identification for radix notoginseng and rhizoma drynariae in the tendon-relaxing and blood-activating bills as well as the content measurement for heavy metals contained by the tendon-relaxing and blood-activating bills. The method comprises the following detection steps: 1, taking ginsenoside Rg1 and ginsenoside Rb1 as reference substances, and adopting the thin layer chromatography identification to determine whether the tendon-relaxing and blood-activating bills contain the radix notoginseng component or not; 2, taking naringin as a reference substance, and adopting the thin layer chromatography identification to determine whether the tendon-relaxing and blood-activating bills contain the rhizoma drynariae component or not; 3, taking standard solutions of five heavy metal elements, i.e., lead, cadmium, arsenic, mercury and copper as reference substan
