Free radical scavenging activity was evaluated using stable DPPH free radical ? The total flavonoids contents TFC were determined following the previously established spectrometric method [ 13 ].
Bioactive Components and Antioxidant Properties of Terminalia arjuna L. Extracts
February 18, ; Published Date: Qasim Ali, Assistant Professor of Botany. February 04, ; Accepted Date: After 5 minutes, 0. Reducing power of extract was determined according to the procedure described previously [ 15 ]. February 28, Citation: The plant Terminalia arjuna L. 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. Ethanol showed relatively low yields as compared to methanol, however, ethanol is even then preferred solvent to extract antioxidant compounds due to it termianlia toxicity.
Bioactive Components and Antioxidant Properties of Terminalia arjuna L.Extracts
It was observed that arjuna extracts contained appreciable amount of TPC 6. 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. Select your language of interest to view the total content in your interested language.
It can be concluded from the results that arjuna extracts were good source of natural antioxidants.

The percentage yield of the extracts was calculated by using the following formula. The plant is very rich source of natural antioxidants due to which it has been activiry investigated for its uses in both Ayurvedic and Yunani systems of medicine [ 78 ]. 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.
Activity of extract increases with the increase in concentration of phenolic compounds. The extraction was executed for 24 hours in an orbital shaker Gallenkamp, U.
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.
All the chemicals and reagents used in this research were of od grade and used were obtained from Sigma Chemical Co. The stem barks and leaves samples were dried by keeping them in open air under shade for three weeks till constant weight was achieved.
A linoleic acid control was performed without the extracts. A raising trend in the yield of antioxidant extracts has been observed with increasing polarity of solvent suggesting the polar natural of antioxidants compounds.
The bark and leave samples of Terminalia arjuna L. The percentage yield of the different arjuna extracts was found in the range of 6.
J Food Process Technol 5: The sample containing butylated hydroxytoulene BHT was used as a positive control. Dry matter extracts mg was mixed with 5. Antioxidant capacities of extracts of were also determined in terms of measurements of inhibition of oxidation in linoleic acid system [ 6 ].
The results suggested that extracts of Terminalia arjuna L. The extraction yields of extracts were ranged from 6.
The mixture was diluted up to 25 mL with distilled water. It was observed that the stem bark extract prepared in methanol, exhibited the highest yield
