Abstract:
Recently, medicinal plants have grabbed attention worldwide in the field of neurosciences for therapeutic intervention. The aim of the study was to identify and measure the total phenolic content (TPC), total flavonoids content (TFC), tannin content (TPC) and total antioxidant capacity (TAC) of the 3 ethanolic extracts. Three ethanolic extracts from two mangrove plants were subjected to the investigation for identifying different antioxidant compounds. For the tests, we used the leaves and aerial root extract from Pandanus foetidus and leaves from Avicennia officinalis. These two are mangroves plants with the evidence of presence of prominent antioxidant properties. The highest phenolic and tannin content were measured about 269mg GAE/gm dry extract and about 212mg AAE/gm dry extract of P. foetidus leaves extract. Total flavonoid content was high in A. officinalis leaves extract which was about 176mg QE/gm dry extract. Aerial root extract of P. foetidus showed lower TPC, TFC and TTC in compare with other extracts. The highest TAC were identified about 212mg AAE/gm dry extract which actually support the highest TAC and TTC in P. foetidus leaves extract. The findings of this study indicate that the different antioxidant compounds in this study may be considered interesting candidates for future research.
