OBJECTIVE： To optimize water extraction technology of Feng-Moutan Cortex. METHODS： L9（34） orthogonal design was used to optimize soaking time， solid-liquid ratio， extraction time and extraction times in water extraction technology of Feng-Moutan Cortex using comprehensive scores for the peak area percentage and extract yield of 8 ingredients in Feng-Moutan Cortex as gallic acid， paeoniflorin， catechin， paeoniflorin， benzoic acid， benzoyloxypaeoniflorin， benzoylpaeoniflorin and paeonol after normalization as indexes. Verification test was conducted. RESULTS： The optimal water extraction technology was that 20-fold water， soaking for 1 h， extracting twice， 2 h each time. Results of verification test showed that comprehensive scores of 3 times of tests were 65.98， 68.85 and 69.25， respectively. RSDs of each index were lower than 5％ （n＝3）. CONCLUSIONS： Established comprehensive scoring method can reflect the relative contents of effective components in Feng-Moutan Cortex comprehen- sively， so that optimized extraction technology is reasonable and feasible.
