Objective: To make full use of cornsilk plant resources ,and to explore the process,the best extraction methods and influencing factors of the cornsilk vitamin E. Method: To apply Soxhlet extraction method and the methyl ester to extract vitamin E of cornsilk , and use UV spectrophotometric to measure the content. Result: By the single factor experiments and orthogonal experimental , the optimum extraction condition follows as: extraction time 2h, Liquid to material' s ratio 1 :10, methylester temperature 70℃ , Methylester time 1 h,the extraction rate 0.056%. Effective factors follows as: methylester time > Methylester temperature > liquid to material' s ratio > extraction time. Conclusion: The test method , a simple easy - to - use, and the high efficiency extraction, less pollution, was an effective way for the extraction of cornsilk vitamin E. The content of cornsilk vitamin E was approximately 0.056% by the experiment, adding the gaps about the area and providing a reference value.
