Comparative analysis of the bioactive compound, pigment content and antioxidant activity in different parts of Pouzolzia zeylanica plant

Abstract

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 (AAI), ferrous reducing ability power (FRAP) and scavenging capacity 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. The results showed that the content of anthocyanin, flavonoid, polyphenol and tannin of young shoots was significantly (PPouzolzia zeylanica plant.
