摘　　要：采用阴干、50℃~90℃烘干及晒干三种常用干燥方式干燥西兰花的花、茎、叶,采用HPLC测定萝卜硫素含量。西兰花不同部位中萝卜硫素含量是种子〉花〉茎〉叶;而不同干燥方法中烘干最好,阴干最差,5种烘干温度中以90℃烘干时萝卜硫素含量最高。西兰花不同部位中种子萝卜硫素含量最高,有10.48 mg/g;而干燥方式采用90℃烘干最佳。Drying Broccoli＇s flower, stalk and leaf with three usual drying methods which were drying in the shade, 50 ℃-90 ℃ drying and drying in the sun,indentifying sulforaphane content with HPLC. Sulforaphane content in broccoli＇s different parts was seed〉flower〉 stalk 〉leaf,with different drying methods ,drying was the best and drying in the shade was the worst,with the five drying temperature it was 90 ℃ that there were the highest sulforaphane content of broccoli, with the different parts the sulforaphane content of broccoli＇s seed was the highest, it had 10.48 mg/g;the best drying methods was 90 ℃ drying.
