ABSTRACT
OBJECTIVE:
To optimize the extraction technology of total saponins from Coreopsis tinctoria.METHODS:
Etha-nol leaching technology was adopted. Based on single factor test,the extraction technology was optimized by orthogonal test using extraction temperature,ethanol volume fraction,extraction time,solid-liquid ratio as factors,extraction rate of total saponins as in-dex. The optimized technology was validated.RESULTS:
The optimal technology was that ratio of solid to liquid was 130 (C. tinctoria-60% ethanol),extracting for 2 h at 50 ℃. Validation test showed that average extraction rate of total saponins was 6.8%(RSD=0.85%,n=3).CONCLUSIONS:
The optimized technology can be used for the extraction of total saponins from C. tinc-toria and keep stable.
