The remaining water in the plant material was removed using paper towel by pressing on them gently. The reducing power of a compound is related to its electron transfering ability and may serve as a significant indicator of its antioxidant activity [ 20 ].
The total flavonoids contents TFC arujna determined following the previously established spectrometric method [ 13 ].
The degree of oxidation was measured following ammonium thiocyanate method [ 15 ]. The oxidation reactions can produce free radicals, which start chain reactions and subsequently can cause a large number of cardiovascular diseases in humans [ 1 ]. Antioxidant capacities of extracts of were also determined in terms of measurements of inhibition of oxidation in linoleic acid system [ 6 acfivity. Agri and Aquaculture Journals Dr. The plant is very rich source of natural antioxidants due to which it has been extensively investigated for its uses in both Ayurvedic and Yunani systems of medicine [ 78 ].
The sample containing butylated hydroxytoulene BHT was used as a positive control. The plant Terminalia arjuna L. The mixture was diluted up to 25 mL with distilled water. The present results suggested that the methanolic extracts of arjuna are more active regarding the phenolic antioxidant compounds that could be exploited as potent source of natural antioxidants for functional food and pharmaceutics. Reducing power of extract was determined according to the procedure described previously [ 15 ].
Extraction yield was dependant on the chemical composition of the bark of tree, as the phenolic and flavonoids contents investigated in the bark extracts Terminalia arjuna from different areas [ 18 ].
terminalix Guidelines Upcoming Special Issues. The stem barks and leaves samples were dried by keeping them in open air under shade for three weeks till constant weight was achieved.
Bioactive Components and Antioxidant Properties of Terminalia arjuna L.Extracts
The maximum amount of TPC All the samples were analyzed in activty. The reducing power was found to be increasing arjuba increasing the concentration of extracts.
The arjuna extracts being a good source of natural antioxidants should be further investigated to explore the chemistry of these extract. Sample containing synthetic antioxidant, BHT was used as positive control. Our finding regarding flavonoids in the present study were comparable with the findings of other researchers [ 16 ] atcivity on antioxidant activity of different plants including Acacia nilotica, Terminalia arjuna, Eugenia jambolana and Azadirachta indica using different solvent blends of ethanol, methanol and water.
In Ayurvedic terjinalia, it is styptic, anthelmintic, alexiteric, tonic, and useful in fractures, heart diseases, urinary discharges, biliousness, ulcers, asthma, tumors, anemia and excessive perspiration etc.
This suggests that extracts of Terminalia arjuna may be explored as a potential source of antioxidants for their use in food and pharmaceutical industries. After 5 minutes, 0.
The samples from 6. Our results are comparable with those ranged from The actuvity extracts from arjuna exhibited a close dependent reducing power and it was observed that reducing power of extracts from different extracts varied to some extent and found in the range of 0. Our findings regarding IC 50 values of arjuna extracts can be correlated with IC 50 values In the present study, it was observed that methanol was an efficient solvent and stem bark extracts of arjuna were more rich in antioxidant compounds.
For extraction of flavonoids compounds, ethanol has been proved very appropriate solvents due to their low toxicity [ 13 ]. The percentage yield of the different arjuna extracts was found in the range of 6. The concentrated extract was allowed to dry at room temperature. BHT provided significantly higher percent inhibition Moreover, there is a growing awareness among consumers regarding food additive safety [ 5 ]. The data regarding the total phenolic contents obtained from different extracts ranged from 6.
Dry matter extracts mg was mixed with 5. The data regarding the percentage inhibition of peroxidation in linoleic acid system from arjuna extracts prepared in different solvent systems is presented in Figure 5.
The antioxidants are molecules capable of decreasing or preventing the oxidation of substrate molecules. Our results in close agreement to the findings of some previous researcher regarding the yield of extract prepared in different blends of methanol solvent [ 16 ].
There is an ongoing quest in progress to search natural antioxidants from plant extracts as a safe alternate of synthetic antioxidants [ 3 ].
The estimation of total phenolic contents TPC was carried out using Folin-Ciocalteu reagent method [ 12 ].
Bioactive Components and Antioxidant Properties of Terminalia arjuna L. Extracts
Free radical scavenging activity was evaluated using stable DPPH free radical ? The earlier investigations in the relevant field had clearly demonstrated that methanol was a promising solvent for extraction of antioxidants from natural products [ 16 ]. Research Article Open Access. Arjuna is used both externally and internally in gleets and urinary discharges as well as expectorant, aphrodisiac, tonic and diuretic [ 10 ]. All the experiments were conducted in three replicates and analyzed in triplicate.

Reducing terminali of ethanolic and methanolic extracts of leaves and stem bark of arjuna at different concentrations. J Food Process Technol 5: The maximum amount of flavonoids 5. K at ambient temperature following the previously established method [ 4 ]. It was observed that the stem bark extract prepared in methanol, exhibited the highest yield Briefly, 50mg of dry mass of extracts was mixed with 0.
