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. The remaining water in the plant material was removed using paper towel by pressing on them gently.
The upper layer of solution 5. All the chemicals and reagents used in this research were of analytical grade and used were obtained from Sigma Chemical Co.

The active components of Terminalia arjuna are tannins, triterpenoid saponin arjunic acid, arjunolic acid, arjungenin, and arjunglycosides [ 11 ]. Ann Jose ankara escort. The amounts of total phenolic were calculated using a calibration curve Gallic acid ppm.
It can be concluded from the results that arjuna extracts were good source of natural antioxidants. February 18, ; Published Date: All the samples were analyzed in triplicates.
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 ]. Please leave a message, we will get back you shortly.

Our finding regarding flavonoids in the present study were comparable with the findings of other researchers [ 16 ] worked 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. The degree of oxidation was measured following ammonium thiocyanate method [ 15 ].
The solution was mixed and the absorbance was measured at nm using a spectrophotometer U, Hitachi Instruments Inc,Tokyoa, Japan. Therefore, this project was designed to investigate bioactive components phenolics and flavonoidsfree radical scavenging property and antioxidant activity of extracts from barks and leaves of arjuna plant indigenous to Pakistan.
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 ]. Our results are comparable with those ranged from The antioxidants are molecules capable of decreasing or preventing the oxidation of substrate molecules. The percentage yield of the extracts was calculated by using the following formula. The maximum percent inhibition of linoleic acid peroxidation The different 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.
For extraction of flavonoids compounds, ethanol has been proved very appropriate solvents due to their low toxicity [ 13 ]. The concentrated extract was allowed to dry at room temperature. The results suggested that extracts of Terminalia arjuna L.
February 28, Citation: The percentage yield of the different arjuna extracts was found in the range of 6. All the experiments were conducted in three replicates and analyzed in triplicate. The plant Terminalia arjuna L.
J Food Process Technol 5: Methanol is generally employed for the extraction of antioxidant components due to their polarity and good solubility with many antioxidant components [ 17 ].
Antioxidant capacities of extracts of were also determined in terms of measurements of inhibition of oxidation in linoleic acid system [ 6 ].
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 data regarding the total phenolic contents obtained from different extracts ranged from 6. 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.
Moreover, there is a growing awareness among consumers regarding food additive actifity [ 5 ]. 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.
K at ambient temperature following the previously established method [ 4 ]. The mixture was kept at room temperature for 10 minutes, and then 1. Activity of extract increases with the increase in concentration of phenolic compounds. The sample containing butylated hydroxytoulene BHT was used as a positive control.
