A raising trend in the yield of antioxidant extracts has been observed with increasing polarity of activitt suggesting the polar natural of antioxidants compounds. Sample containing BHT served as positive control. There is an ongoing quest teerminalia progress to search natural antioxidants from plant extracts as a safe alternate of synthetic antioxidants [ 3 ].
For extraction of flavonoids compounds, ethanol has been proved very appropriate solvents due to their low toxicity [ 13 ]. All the chemicals and reagents antioixdant in this research were of analytical grade and used were obtained from Sigma Chemical Co.
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 ].
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
Antioxidant compounds terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves [ 2 ]. The total flavonoids contents TFC were determined following the previously established spectrometric method [ 13 ]. Agri and Aquaculture Journals Dr. Many plant based compounds such as ascorbic acid, polyphenols, vitamin E, carotenes, xynthophylls and tannins had been investigated for their antioxidant potential to be used in different food products to improve their shelf life and functional properties [ 6 ].
Teminalia of extract increases terinalia the increase in concentration of phenolic compounds. A number of studies are available on the antioxidant activity and medicinal importance of this plant worldwide, whereas, in Pakistan no remarkable research work has been conducted while the plant is easily available due to favorable agro-climatic conditions for its growth. 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.
Terminalia arjuna based phytochemicals are considered as one of the best heart tonic [ 7 ] therefore, it can be used on daily bases as tonic for healthy cardiovascular system. The concentrated extract was allowed to dry at room temperature.
Guidelines Upcoming Special Issues. The mixture was diluted up to 25 mL with distilled water. Moreover, there is a growing awareness among consumers regarding food additive safety [ 5 ].
The degree of oxidation was measured following ammonium thiocyanate method [ 15 ]. The data regarding the total phenolic contents obtained from different extracts ranged from 6. Authenticated samples of leaves and bark were separately packed in polythene bags and transferred to the Natural Products Research Laboratory, Government College University Faisalabad. The maximum amount of flavonoids 5.
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 ]. The amounts of total phenolic were calculated using a calibration curve Gallic acid ppm.
This suggests that extracts of Terminaliz arjuna may be explored as a potential source of antioxidants for their use in food and pharmaceutical industries. The extraction yields of extracts were ranged from 6. K at ambient temperature following the previously established method [ 4 ].

Two different solvent systems aqueous ethanol water: The maximum amount of TPC Ann Jose ankara escort. Antioxidant capacities of extracts of were also determined in terms of measurements of inhibition of oxidation in linoleic acid system [ 6 ]. Our results of present study are in close agreement with the findings 0. Percent inhibition of linoleic acid peroxidation by synthetic antioxidant BHT was taken as control and compared with arjuna extracts.
