08mol/L) sulfur-barbitone was put in the colorimetric tube, then the solution was diluted to scale, shake up , after it was placed for a period of time, measure its absorbency with the blank sample in 1 cm colorimetric ware.
2紫外分光光度法检测茴香醛含量的最佳的反应条件：将稀释到一定比例的样品1mL于10mL具塞比色管中，加入6mol／L盐酸2mL，然后加入0.08mol／L硫代巴比妥酸溶液2mL，用蒸馏水稀释至刻度，摇匀，放置一段时间后，用1cm比色皿，以空白样为参照，测量其吸光度值。
