%X By using ultrasonic extraction and spectrophotometry methods, changes of flavonoids content in <em>Catharanthus roseus</em> during different developmental periods were studied. The results showed that, The sequence of the flavonoids content in different parts of <em>C. roseus</em> during every periods from highest to lowest is following: fruit, leaf, flower, stem, root. The sequence of flavonoids content of leaves on three different positions from the highest to the lowest is following: flower leaves, fruit leaves, nutrition leaves,the sequence of flavonoids content of branches on three different positions from the highest to the lowest is following: fruit branch, leaf branch, stem, which form a top-to-down degressivn trend. The total flavonoids content of all side branches was higher than that of main branch. In contrast with tap root, the flavonoids content of fibrous roots were higher. Which form a outer-to-inner descending trend.
