Using the assay systems of spectrophotometric method,we determined the variation of the total phenolics content and antioxidant activity in different organs of Capparis spinosa in different months which collected from the south part of Xinjiang.The results showed that:(1)Thephenolics distribute in every organs of C.spinosa in every months,in which the flowers ranged of the highest one in all organs,while the lowest was stem.In addition,dynamic changing of total phenolics content display that the highest level in flowers in May,as the time goes by the total phenolics content in flowers was reducing.It is similar tendencies of the total phenolics concentration changed in other organs except stem.(2)The different extracts all have antioxidant activity,the flowers extract shows the strongest and the stem extract shows the weakest.The antioxidant activity of the flowers extract is weaker with the time changing.
