COMPARATIVE STUDY OF ANTIOXIDANT ACTIVITIES OF CASSIA AURICULATA AND CASSIA SIAMEA FLOWERS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 12
Abstract
Medicinal plants are source of important therapeutic aids for alleviating human ailments. The history of drug is intricately interowen with natural products for centuties. In tune with this effort, the objective set for the present investigation is to estimate the phenolic and flavonoid contents in flower extracts of Cassia auriculata and Cassia siamea. The preliminary qualitative screening revealed the presence of important secondary metabolites in both the species responsible for the antioxidant potential. Invitro assays to assess the antioxidant activities: DPPH- radical scavenging activity, reducing power, inhibition of lipid peroxidation gave fruitful results. Methanol extract of Cassia auriculata showed its superfluous scale comparatively higher with extracts of Cassia siamea. SC50/ EC50/ IC50 values calculated were also found to be significant for methanolic extract of Cassia auriculata, thus being in agreement with contents. Thus, the results of this study would certainly help to ascertain the potency of those extracts as potential source of natural antioxidants.
