COMPARISON OF ANTIOXIDANT POTENTIAL OF FRESH AND MARKETED SAMPLES OF MEDICINAL PLANT- ECLIPTA ALBA
AbstractThe present study aimed at comparing the antioxidant potential of three different samples of Eclipta alba-fresh plant, marketed leaf powder (packaged in sealed containers), and marketed whole plant (sold in open bags). The presence of alkaloids, saponins, triterpenes, terpenoids, tannins, steroids, flavonoids, glycosides was confirmed in all three samples. Fresh plant samples showed a higher antioxidant activity determined using standard ferric reducing antioxidant power (FRAP) assay (3105.16 ± 202.07 AAE/gm. dry weight) and 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) assay (32.37 ± 5.94%). Fresh plant samples also had a higher content of secondary metabolites such as total phenolics and alkaloids as compared to the other two samples. A high correlation was observed between antioxidant capacity and total phenolic content (R2 = 0.997). Loss of antioxidant potential in marketed samples indicates that proper processing and storage are important in ensuring the viability of the raw material of medicinal plants.
