ABSTRACT
OBJECTIVE:
To optimize the extraction technology of Duoxuekang.METHODS:
Using comprehensive score of salidroside,gallic acid content and extraction yield as indexes,U6(63)uniform design was designed to optimize the liquid-solid ra-tio,ethanol volume fraction and extraction time of Duoxuekang,then optimize extraction times,and verification test was conduct-ed.RESULTS:
The optimal extraction technology was as follows as 50% ethanol,liquid-solid ratio of 114,soaking time of 1.5 h,reflux extraction for 1 h and repeated twice;the average extraction yield in 3 tests was 50.18%,contents of salidroside and gal-lic acid were 1.82 mg/g,16.54 mg/g (RSD≤0.84%,n=3).CONCLUSIONS:
The optimized extraction technology for Duox-uekang is reasonable,simple and feasible.
