The plant part was extracted with methanol to yield the crude extract. The antimicrobial activity test of the methanol extract of the bark of Terminalia arjuna was done using disc diffusion method. All the microorganisms were susceptible in various degrees to the extract. The methanol extract was found to be moderately active against Staphylococus aereus, Bacillus megaterium, Bacillus subtilis Salmonella typhi, Escherichia coli and Pseudomonas aeruginosa.

Vudojar 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 antioxidants are molecules capable antioxidaant decreasing or preventing the oxidation of substrate molecules. 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.
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. The active components of Terminalia arjuna are tannins, triterpenoid saponin arjunic acid, arjunolic acid, arjungenin, and arjunglycosides [ 11 ]. The total flavonoids contents TFC were determined following the previously established spectrometric method [ 13 ].
Dry matter extracts abtioxidant was mixed with 5. The stem barks and leaves samples were dried by keeping them in open air under shade for three weeks till constant weight was achieved. February 28, Citation: Two different solvent systems aqueous ethanol water: Our findings regarding TPC of arjuna extracts were found in a close agreement with the findings 7.
Extracts Ann Jose ankara escort. The data regarding the total phenolic contents obtained from different extracts ranged from 6. Antioxidant compounds terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves [ 2 ]. BHT provided significantly higher percent inhibition A linoleic acid control was performed without the extracts. For extraction of flavonoids compounds, ethanol has been proved very appropriate solvents due to their low toxicity [ 13 ].

The arjuna extracts are found to be quite effective in preventing the oxidation.
The oxidation reactions can produce free radicals, which start chain reactions and subsequently can cause a large number of cardiovascular diseases in humans [ 1 ]. Extracts TFC amounts were expressed as catechin equivalents per hundred grams of dry matter. Extraction yield was dependant on the chemical composition of the bark of tree, as the phenolic and flavonoids contents investigated in the bark extracts Terminalia arjuna from different areas [ 18 ].
Our finding regarding flavonoids in the present study were comparable with the findings of other researchers [ 16 ] worked on antioxidant activity of different if including Acacia nilotica, Terminalia arjuna, Eugenia jambolana and Azadirachta indica using different solvent blends of ethanol, methanol and water. Home Publications Conferences Register Contact. Actlvity containing BHT served as positive control. All the chemicals and reagents used in this research were of analytical grade and used were obtained from Sigma Chemical Co.
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 maximum amount of flavonoids 5. Pharmaceutical Sciences Journals Ann Jose ankara escort. Authenticated samples of leaves and bark were separately packed in polythene bags and transferred to the Natural Products Research Laboratory, Government College University Faisalabad.
The percentage yield of the different arjuna extracts was found in the range of 6. Moreover, there is a growing awareness actiivity consumers regarding food additive safety [ 5 ]. The upper layer of solution 5. Briefly, 50mg of dry mass of extracts was mixed with 0. Total phenolic contents of extracts was determined by Folin- Ciocalteu reagent due to its high specificity for the polyphenolic compounds present in plant extracts as it did not interact with the other phytochemicals due to a complex formation between reducing species and phosphors-molybdic tungstate.
The maximum percent inhibition of linoleic acid peroxidation J Food Process Technol 5: Terminalia arjuna based phytochemicals are considered as one of the best heart tonic [ acfivity ] therefore, it can be used on daily bases as tonic for healthy cardiovascular system.

Abstract Terminalia arjuna T. The lipid lowering activity of these four fractions A, B, C, and D was evaluatedin vivo in two models viz. Hyperlipidemia induced by triton caused marked increase in the plasma levels of total cholesterol Tc , triglyceride Tg and phospholipids PL in rats. After treament withT. After treatment withT.

Its bark decoction is being used in the Indian subcontinent for anginal pain, hypertension, congestive heart failure, and dyslipidemia, based on the observations of ancient physicians for centuries. The utility of arjuna in various cardiovascular diseases needs to be studied further. Therefore, the present review is an effort to give a detailed survey of the literature summarizing the experimental and clinical studies pertinent to arjuna in cardiovascular disorders, which were particularly performed during the last decade.
