Journal Title: International Journal of Pharmaceutical Sciences and Research (IJPSR) - Year 2019, Vol 10, Issue 6
Abstract
The Phlogacanthus thyrsiflorus roots have been used by the tribal population of western Assam to treat the hepatic disorder. The present study focuses on phytochemical screening, GC-MS analysis and in-vitro antioxidant activities using different extracts. Plant total phenolics, flavonoids, reducing power assay and antioxidant activity was evaluated. DPPH, FRAP, ABTS, Metal chelating activity, and H2O2 free radical scavenging activity were studied. The screening from extracts showed the presence of phenols, flavonoids, tannins, resins, terpenoids, alkaloids, glycosides, cardiac glycosides, steroids. The highest concentration of total phenolics, flavonoids, reducing power and total antioxidant activity was found in the hydro-alcoholic extract of RoPt. The results of the radical scavenging activity in 70% ethanolic extract showed better IC50 value in DPPH (265.87 ± 17.58), ABTS (17.89 ± 1.18) and H2O2 (17.89 ± 1.05) µg/ml respectively. EC50 value of 535.16 ± 34.82 was found in 70% ethanolic against 1471.32 ± 19.77 µg/ml of acetone extract whereas the FRAP showed high FeSO4.7H2O concentration in acetone extract with 820 ± 9.1 µM/ml. The major chemical constituents that were identified in GC-MS analysis were 2R-Acetoxymethyl-1,3,3-Trimethyl-4T-(3-Methyl-2-Buten-1-YL)-1T- Cyclohexanol (71.243%) and 2,4,4-Trimethyl-3-Hydroxymethyl -5A-(3-Methyl-But-2-Enyl)- Cyclohexene (88.107%) in hydro-alcoholic and acetone extracts respectively. The study showed an enhanced phenolic and flavonoid concentration and radical scavenging activity in the 70% ethanol extracts of RoPt which are the good source of antioxidants showing potential in preventing much free radical-mediated disorder.
