Plants are a rich source of therapeutically active compounds such as antioxidants, antibiotics, pigments, vitamins, organic acids, glycosides, and other substances of particular importance to human life.  The present study was to analyze and compare the content of bioactive compounds (anthocyanin, flavonoid, polyphenol and tannin); pigments (chlorophyll a, chlorophyll b, total chlorophyll and carotenoids); and antioxidant activity in different parts of Pouzolzia zeylanica plant. The antioxidant activities were evaluated using three methods such as antioxidant ability index, ferrous reducing ability power, and scavenging capacity 2,2-diphenyl-1-picrylhydrazyl radical. The results showed that the content of anthocyanin, flavonoid, polyphenol and tannin of young shoots was significantly (P<0.01) higher than that of other parts. In constrast, the content of pigments such as chlorophyll a, chlorophyll b, total chlorophyll and carotenoids of leaves was higher than that of young shoots, whole plants and stems. Besides, the antioxidant capacity of young shoots was also higher than that of leaves, whole plants and stems when performed with three assay methods. It was a correlation between the content of bioactive compounds and antioxidant activities of different parts of Pouzolzia zeylanica plant.
