Optimization of the Extraction Technology of Qingjie Atomized Liquid by Orthogonal Test / 中国药房

OBJECTIVE:To optimize the extraction technology of Qingjie atomized liquid. METHODS:The extraction technol-ogy of Qingjie atomized liquid was optimized by orthogonal test with hyperoside content as index,using the amount of added wa-ter,extraction time and extraction times as factors,and the verification test was conducted. RESULTS:The optimal extraction tech-nology was as follows as 12-folds water,extracting for 2 times and 1 hour each time. The content of hyperoside was 4.129 μg/g in 3 validation tests(RSD=1.81%,n=3). CONCLUSIONS:The optimal extraction technology is stable and practical,and can pro-vide reference for the formulation of technology and quality standard for Qingjie atomized liquid.
