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 antiioxidant in aqueous ethanol water: Can’t read the image?
Our results are comparable with those ranged from The amounts of total phenolic were calculated using a calibration curve Gallic acid ppm. The absorbance of the resulting solutions and the blank were recorded after 1 hour at room temperature. It was observed that the stem bark extract prepared in methanol, exhibited the highest yield Agri and Aquaculture Journals Dr. The maximum amount of flavonoids 5.
The maximum percent inhibition of linoleic acid peroxidation Percent inhibition of linoleic acid was rajuna as. The results suggested that extracts of Terminalia arjuna L.
The mixture was kept at room temperature for 10 minutes, and then 1. Reducing power of extract was determined according to the procedure described previously [ 15 ]. The extraction was executed for 24 hours in an orbital shaker Gallenkamp, U. Guidelines Upcoming Special Issues. A raising activitu in the yield of antioxidant extracts has been observed with increasing polarity of solvent suggesting the polar natural of antioxidants compounds.

Our findings regarding IC 50 values of arjuna extracts can be correlated with IC 50 values Where, A blank is the absorbance of the control reaction mixture, and A sample is the absorbance of the sample. Methanol is generally employed for the extraction of antioxidant components due to their polarity and good solubility with many antioxidant components [ 17 ]. Percent inhibition of linoleic acid peroxidation by synthetic antioxidant BHT was taken as control and compared with arjuna extracts.
Please leave a message, we will get back you shortly. It can be concluded from the results that arjuna extracts were good source of natural antioxidants.
Bioactive Components and Antioxidant Properties of Terminalia arjuna L. Extracts
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. Our results of present study are in close agreement with the findings 0. 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 total flavonoid contents, 1. It was observed that arjuna extracts contained appreciable amount of TPC 6. The methanol aarjuna be exploited for the extraction of effective antioxidant components from the plant material. The stem barks and leaves samples were dried by keeping them in open air under shade for three weeks till constant weight was achieved. Activity of extract increases with the increase in concentration of phenolic compounds.
The specimens was further identified and authenticated from Dr.
Sample containing synthetic antioxidant, BHT was used as positive control. Arjuna is used both externally and internally in gleets and urinary discharges as well as expectorant, aphrodisiac, tonic and diuretic [ 10 ]. TFC amounts were expressed as catechin equivalents per hundred grams of dry matter. Ann Jose ankara escort. After 5 minutes, 0.
This suggests that extracts of Terminalia arjuna may be explored as a potential source of antioxidants for their use in food and pharmaceutical industries. February 28, Citation: 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.
Authenticated samples of leaves and bark were separately packed in polythene bags and transferred to the Natural Products Research Laboratory, Government College University Faisalabad.
Flavonoids arjunone, arjunolone, luteolingallic acid, ellagic acid, Oligomeric Proanthocyanidines OPCsphytosterols, calcium, magnesium, zinc and copper [ 10 ].
