Study on Extraction Technology of the Flos Carthami with Orthogonal Test

Objective：To optimize the extraction technology of the Flos Cartharni. Method：Use the orthogonal experiment method, to inspect the effect to withdraw efficiency by the leaking speed, the alcoholic degree, the gathering quantity, with the carthmidin and the saffloryyellow being the target. To optimize the best withdraw condition of the Flos Carthami. Result： The best withdraw condition for the Flos Carthami： 50 % alcohol as the solvent, the leaking speed with （1- 3） ml·min^-1·kg^-1, gathering 5 times of solution. Conclusion： Optimization of extraction technology of the Flos Carthami with orthogonal test was scientific and feasible.
