OBJECTIVE： To compare the quality control index between Jinzhen Suanzao teabag and decoction， and explore the alternative supplement of teabag to decoction. METHODS： The test sample solutions of Jinzhen Suanzao teabag and decoction were prepared by hot-maceration method and water-decoction method. The contents of water soluble extract and total flavonoids were determined and compared between 2 kinds of preparation. The leaching rates of teabag were investigated at different soak time （0， 5， 10， 15， 20， 25， 30 min） to optimize soaking time. RESULTS： The average content of water soluble extract were 50.56％ and 44.45％ （P＜0.05） respectively for the teabag and decoction. The total flavonoids content were 0.64 mg/g and 0.69 mg/g （P＜0.05）. The dissolution amount of teabag were increasing and leaching rate increased within first 20 min， and reached balance gradually 25 min later. CONCLUSIONS： According to the convenience of use and results of each index， the difference in quality control index is not great between 2 kinds of preparation. Teabag can be as the supplement of decoction.
