Huangqin (Scutellaria Radix) is a traditional Chinese medicine. Scutellaria extract and main active ingredient baicalin have become an indispensable and important raw material in modern Chinese medicine preparations. The preparation technology, quality standards, regulatory policies and application status of Scutellaria extract and baicalin in Chinese patent medicine were reviewed. Scutellaria extract is managed as a traditional Chinese medicine extract and can only be used for oral Chinese patent medicine; Baicalin is used as a chemical raw material for association review. Its application scope is wider. In addition to oral Chinese patent medicine, it can also be used in injection, eye drops and other dosage forms. Scutellaria extract and baicalin are mixtures with baicalin as the main component, but the quality standard is a single baicalin as the quality control index. Many Chinese patent medicines containing Scutellaria extract and baicalin have been included in the medical insurance catalog and the list of over-the-counter drugs, indicating the importance of baicalin as a raw material of Chinese patent medicines. In order to ensure the safety and effectiveness of drug use, especially for baicalin for injection, we should further strengthen the control of exogenous pollutants and establish a multi-component total quality control system in the future.
