Bioactive Components and Antioxidant Properties of Terminalia arjuna L.Extracts
Can’t read the image? In Ayurvedic system, it is styptic, anthelmintic, alexiteric, tonic, and useful in fractures, heart diseases, urinary discharges, biliousness, ulcers, asthma, tumors, anemia and excessive perspiration etc. The degree of oxidation was measured following ammonium thiocyanate method [ atioxidant ]. There is an ongoing quest in progress to search natural antioxidants from plant extracts as a safe alternate of synthetic antioxidants [ 3 ].
The amounts of total phenolic were calculated using a calibration curve Gallic acid ppm. Upon arrival in the laboratory the leaves and stem bark samples were washed thoroughly with tap water to remove any wastes and dust particles.
Dry matter extracts mg was mixed with 5. BHT provided significantly higher percent inhibition Antioxidant compounds terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves [ 2 ].
February 18, ; Published Date: The sample containing butylated hydroxytoulene BHT was used as a positive control. Briefly, 15 gram of ground material was taken in conical flask followed terminxlia the addition of mL of each solvent activitty. Our results of present study are in close agreement with the findings 0.
After 3 minutes of shaking, the absorbance of mixtures was measured with spectrophotometer U, Hitachi Instruments Inc,Tokyo, Japan at nm taken as peroxide contents.
Briefly, 50mg of dry mass of extracts was mixed with 0. Sample containing BHT served as positive control.
Bioactive Components and Antioxidant Properties of Terminalia arjuna L. Extracts
Ann Jose ankara escort. K at ambient temperature following the previously established method [ 4 ]. Percent inhibition of linoleic acid peroxidation by synthetic antioxidant BHT was taken as control and compared with arjuna extracts.
The data regarding the total phenolic contents obtained from different extracts ranged abtioxidant 6. The data regarding the total flavonoid contents, 1. The specimens was further identified and authenticated from Dr.
actviity Activity of extract increases with the increase in concentration of phenolic compounds. The stem barks and leaves samples were dried by keeping them in open air under shade for three weeks till constant weight was achieved. This work was carried out to investigate the antioxidant activity and free radical scavenging capacity of leaves and stem bark extracts of Terminalia arjuna arjuna prepared in aqueous ethanol water: Reducing power of ethanolic and methanolic extracts of leaves and stem bark of arjuna at different concentrations.
Sample containing synthetic antioxidant, BHT was used as positive control. Ethanol showed relatively low yields as compared to methanol, however, ethanol is even then preferred solvent to extract antioxidant compounds due actibity it lower toxicity. J Food Process Technol teerminalia 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.

TFC amounts were expressed as catechin equivalents per hundred grams of dry matter. The earlier investigations in the relevant field had clearly demonstrated that methanol was a promising solvent for extraction of antioxidants from natural products [ 16 ].
Qasim Ali, Assistant Professor of Botany. February 28, Citation: The active components of Terminalia arjuna are tannins, triterpenoid saponin arjunic acid, arjunolic acid, arjungenin, and arjunglycosides [ 11 ].
The extraction yields of extracts were ranged from 6. Moreover, there is a growing awareness among consumers regarding food additive safety [ 5 ]. Our findings regarding TPC of arjuna extracts were found in a close agreement with the findings 7.
Reducing power of extract was determined according to the procedure described previously [ 15 ]. The absorbance of the resulting solutions and the blank were recorded after 1 hour at room temperature.

Flavonoids arjunone, arjunolone, luteolingallic acid, ellagic acid, Oligomeric Proanthocyanidines OPCsphytosterols, calcium, magnesium, zinc and copper [ 10 ].
Free radical scavenging activity was evaluated using stable DPPH free radical ? The antioxidant capacities of arjuna extracts were also evaluated by measuring their free radical scavenging abilities to 1,1 —diphenyl-2 picrylhydrazyl DPPH stable following the previously established method [ 14 ] with slight modifications.
