The maximum amount of TPC 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 oxidation reactions can produce free radicals, which start chain reactions and subsequently can cause a large number of cardiovascular diseases in humans [ 1 ]. The methanol can be exploited for the extraction of effective antioxidant components from the plant material.
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. Agri and Aquaculture Journals Dr. The plant Terminalia arjuna L. Our results of present study are in close agreement with the findings 0. The mixture was kept at room temperature for antuoxidant minutes, and then 1. Sample containing BHT served as positive control. The reducing power was found to be increasing by arjunaa the concentration of extracts.
The upper layer of solution 5. The arjuna extracts are found to be quite effective in preventing the oxidation. Ethanol showed relatively low yields as compared to methanol, however, ethanol is even then preferred solvent to extract antioxidant compounds due to it lower toxicity. February 04, ; Accepted Date: Can’t read the termnialia In the present study, it was observed that methanol was an efficient solvent and stem bark extracts of arjuna were more rich in activith compounds.
Home Publications Conferences Register Contact. 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. Methanol is generally employed for the extraction of antioxidant components due to their polarity and good activitty with many antioxidant components [ 17 ]. Sample containing synthetic antioxidant, BHT was used as positive control.
Antioxidant compounds terminate these chain reactions by removing free arhuna intermediates, and inhibit other oxidation reactions by being oxidized themselves [ 2 ].
Bioactive Components and Antioxidant Properties of Terminalia arjuna L. Extracts
It was observed that the stem bark extract prepared in methanol, exhibited the highest yield The extraction yields of extracts were ranged from 6.

The amounts of total phenolic were calculated using a calibration curve Gallic acid ppm. The highest yield of methanolic stem bark extract as established in the present analysis revealed the greater efficiency of methanol as extracting solvent and that might be attributed to the high polarity of the methanol: The solution was mixed and the absorbance was measured at nm using a spectrophotometer U, Hitachi Instruments Inc,Tokyoa, Japan.
Reducing power of extract was determined according to the procedure described previously [ 15 ].
All the samples were analyzed in triplicates. 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: Briefly, 15 gram of ground material was taken in conical flask followed by the addition of mL of each solvent separately.
Our findings regarding IC 50 values of arjuna extracts can be correlated with IC 50 values All the experiments were conducted in three replicates and analyzed in triplicate.
Our results are comparable with those ranged from Two different solvent systems aqueous ethanol water: 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 percentage yield of the different arjuna extracts was found in the range of 6. The results suggested that extracts of Terminalia arjuna L.
The degree of oxidation was measured following ammonium thiocyanate method [ 15 ]. Therefore, this project was designed to investigate bioactive components phenolics and flavonoids ariuna, free radical scavenging property and antioxidant activity of extracts from barks and leaves of arjuna plant indigenous to Pakistan.
Free radical scavenging activity was evaluated using stable DPPH free radical ? 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. Qasim Ali, Assistant Professor of Botany.

Terminala Upcoming Special Issues. The synthetic antioxidants butylated hydroxyanisole, butylated hydroxytoluene, tertiary butyl hydroxyquinone and propyl gallate being used in food products to prevent oxidative damages in terms of food spoilage and rancidity in fatty foods [ 3 ] had been band in advanced countries and being discouraged even in developing countries due to their perceived carcinogenic attributes and other toxic properties [ 4 ]. Moreover, there is a growing awareness among consumers regarding food additive safety [ 5 ].
