Ethnobotany Olanipekun, Mary [1], Obembe, Olusola Michael [2]. Phytochemical contents and antioxidant potential of leaves extracts of Aspidistra elatior, Chromolaena odorata, Pennisetum pedicellatum and Stigma maydis in Ekiti State Nigeria. ABSTRACT
Background: Aspidistra elatior, Chromolaena odorata, Pennisetum pedicellatum and Stigma maydis are used in traditional medicine for the treatment of various diseases conditions. However, there are paucity of information on the phytochemical and antioxidant potential of their bioactive contents in the study area.
Methods: This study was designed to investigate the phytochemical and the antioxidant activities of the extracts of Aspidistra elatior, Chromolaena odorata, Pennisetum pedicellatum and Stigma maydis leaves using distilled water as extraction solvents. The total alkaloids, saponins, phenolic acid and flavonoids were determined spectrophotometrically while antioxidant potentials were evaluated with 2,2-diphenyl-1-picrylhydrazyl (DPPH), Ferric-reducing antioxidant power (FRAP) and nitric oxide (NO) protocols.
Results The phytochemical evaluation of the leaves of Aspidistra elatior, reveals high contents of phenol (196.10 ± 1.49) mg/GAE/g, and saponins (16.64 ± 0.39) mg/GAE/g respectively while Stigma maydis contains high glycosides contents of (22.44 ± 0.05) mg/GAE/g. In addition, Flavonoids content was the highest in Aspidistra elatior (8.08 ± 0.05) QE/g while tannins, saponins, terpenoids were present at varying levels in all the samples. However, alkaloids, saponins and steroids were not detected in Chromolaena odorata, Stigma maydis, Pennisetum pedicellatum respectively. All the extracts of the plant samples showed significant antioxidant activities with FRAP, DPPH and NO along a concentration gradient.
Conclusion: These results showed that the plants samples contain bioactive secondary metabolites with potent-free radical scavenging activities, which could be extracted and standardized for use as food, medicine, and in industries. Thus, supports and justifies their use in folk medicine Keywords: Phytochemicals, antioxidants, bioactive, extracts, steroids
