Quality control method of tablet capable of clearing lung and inhibiting fire

The invention relates to a quality control method of a tablet capable of clearing lung and inhibiting fire, which comprises the following steps of: adopting thin-layer chromatography to identify whether components such as gardenia, golden cypress, radix sophorae flavescentis and rheum officinale are contained in the formula of the tablet capable of clearing lung and inhibiting fire; taking baicalin as a contrast product; and adopting high efficiency liquid chromatography to measure the content of scutellaria baicalensis in the tablet capable of clearing lung and inhibiting fire. As an original quality standard does not have corresponding control standards, in the invention, thin-layer identification experiments are performed on the gardenia, golden cypress, radix sophorae flavescentis and rheum officinale, methods of screening materials characterized in good reproducibility, strong specificity, clear color development of spots, and easy judgment of results are contained in the standard; and based on the revis
