RESUMEN
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 de-termined 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 gradu-ally 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.
