Objective: To determine optimum extraction technology of Inula helenium. Method: Orthogonal test was used to optimize extraction technology of I. helenium with the content of alantolactone and isoalantolactone as indexes. Effect of the concentration of ethanol
the amount of solvent
extraction time and extraction times were investigated
the content of index components were determined by HPLC. Result: Optimum extraction technology was as follows:refluxing extracted 3 times with 15 times the amount of 85% ethanol
1 h each time. Conclusion: This optimized extraction technology was stable and feasible with high extraction ratio
it could provide scientific basis for extraction of I. helenium.
