[Review of chemical constituents, pharmacological effects and clinical applications of Suanzaoren Decoction and prediction and analysis of its Q-markers].

Suanzaoren Decoction is a classic prescription for nourishing the heart and liver, nourishing blood and tranquilizing the mind. It has the functions of sedation and hypnosis, anti-anxiety, anti-depression, anti-convulsion and so on. Modern clinic is mostly used to treat different types of insomnia, depression, neurasthenia, tension headache and vertigo. In this paper, the chemical consti-tuents, pharmacological effects and clinical application of Suanzaoren Decoction are reviewed. Based on this, the quality marker(Q-marker) of Suanzaoren Decoction was predicted and analyzed according to the "five principles" of Q-marker of traditional Chinese medicine--transmission and traceability, specificity, effectiveness, measurability and compatibility environment of compound prescriptions. The results indicated that jujuboside, spinosin, ferulic acid, senkyunolide Ⅰ, sarsasapogenin, mangiferin, liquiritoside and glycyrrhizic acid were predicted and analyzed, and those can be used as Q-markers of Suanzaoren Decoction. Subsequently, the above components can be selected as indicators to control and evaluate the quality of Suanzaoren Decoction and its preparations, and establish a quality traceability system.
