Studies On Phytochemical Screening And Antioxidant Activity Of Chromolaena Odorata And Annona squamosa
The aim of this study was to investigate the phytochemical composition and antioxidant activity of Chromolaena odorata and Annona squamosa collected from Ooty hills and Ealagiri hills respectively. The leaf extract of Chromolaena odorata and seed extract of Annona squamosa with different solvents were investigated. The phytochemical composition was carried on the leaf extracts of Chromolaena odorata and seed extract of Annona squamosa, revealed the presence of active ingredients such as glycosides, steroids, Saponins, Phenols, Flavonoids, Terpenoids and Tanins. The leaf extracts and seed extracts were evaluated for antioxidant activities by DPPH radical scavenging assay. Among three accessions with different solvents used, maximum antioxidant activity found ethanolic leaf extract from Chromolaena odorata and seed extract of Annona squamosa followed by others. The present study reveals that these plants are of therapeutic potential due to their high free radical scavenging activity.
