The survey proposed on the works Terninalia arjuna belongs to the household Combretaceae.

T. arjuna traditionally known to be used to bring around many wellness related issues such as bosom complaints, diabetics and besides has wound mending belongings. Earlier studies on this tree show that it can be used as Anti-HIV, Anti-Tumor, Hepatotoxicity drug etc. The tree is widely distributed throughout India and largely seen in Western Ghats. In this survey the T. Arjuna bark and nucleus wood were collected from Tirunelveli District.

, Tamil Nadu. After aggregation, the tree parts were subjected to consecutive extraction utilizing methyl alcohols and H2O in turn. Following, different concentrations of both infusions will be used to research the Hemolytic, larvicidal, consequence of pH, presence of toxic heavy metals and antimicrobic check on selected microbic species. ( Include the Results – in short )Keywords: T. Arjuna, Hemolytic Assay, Larvicidal Activity, Antimicrobial check, Core Wood and BarkGuide: Dr. Padma ThiagarajanProfessor, SBSTVIT University, Vellore 632014Tamil Nadu, India.


In developing states, mortality due to malarial infection among kids is going a major issue.

In India the etiology is due to un-hygiene pattern which leads to high genteelness of Anopheles, ensuing in terrible illness [ 1, 2 ] . The antibiotic immune form of these mosquito larvae have been altering often. There is a demand for set uping a peculiar type of drug which is harmful to larvae without set uping human system. Hemolytic check is besides performed to look into the consequence of infusion on human. As Red Blood Cells resemble the mechanism of other cells, the survey was designed to look into the consequence of infusions for haemolysis.Many workss in India are used in common people traditional knowledge medical specialty for intervention of larval infections [ 3 ] .

The possible benefits of herbal medical specialties would lie in their efficaciousness, safety, small or no side effects and comparatively low cost. In India, there are several hundred workss belong to the household Combretaceae such as T.arjuna have been reported to incorporate a broad scope of secondary metabolites that have a cytotoxic effects [ 4 ] . These cytotoxic effects have been demonstrated in experiments performed. However non much work has been done on the antibacterial activity of roots, foliages and fruits of the present work we describe antibacterial activity of aqueous and methanol infusions of bark and corewood.

The medicative value of workss prevarications in some chemical substances that produce a definite physiological action on the human organic structure. Screening of medicative workss for elementological activities are of import for happening possible new compounds for curative usage. Screening of medicative workss for elementological activities are of import for happening possible new compounds for curative usage. ( 16 ) Total three elements ( Zn, Cd and lead ) are analysed in these works infusions.


Natural stuffs: The bark and nucleus wood of T. Arjuna was powdered and extracted utilizing soxhlet setup with methyl alcohol and H2O as dissolvers harmonizing to the criterion protocols.

[ 5 ]Blood sample: Blood sample collected from the healthy giverLarva: Mosquito Larvae collected from H2O beginningChemicals: Phosphate buffer saline and 1 % saline, concentrated sulfuric acid, Muller Hinton Agar, lead nitrate, Cd chloride, Zn sulfate.Instrumentality: extractor micro pipette, spectrophotometer, pH metre, atomic soaking up spectrophotometer.Clinical samples: Staphylococcu sp, E.coli, Pseudomonas, Candida sp, Bacillus sp.

2.1 Hemolytic check:Hemolytic check was performed harmonizing to the method described by Bulmus et Al. [ 6 ] 5ml of blood is collected from healthy giver and centrifuged at 2000 revolutions per minute for 15 proceedingss. To the volume of plasma aspirated equal volume of PBS is added. The full plasma is washed utilizing PBS. The excess PBS is removed and after the cells settle they are diluted by a factor of 10 % .

This mixture ( RBC +PBS ) is made up to a volume of 20ml. Different concentrations ( 50,250,500 ) of the aqueous and methanolic infusion is prepared utilizing PBS. To 1.5ml of each of these concentrations incorporating RBC and PBS, 1.

5ml of sample is added. This is incubated in a H2O bath at 370 C for 60 proceedingss. The mixture is so centrifuged and supernatant is used to look into for the optical density at 541 nanometer with methyl alcohol as space and Triton ten as a negative control.2.2 Larvicidal checkThe check was carried out harmonizing to the method described by WHO, 2005 [ 7 ] .

Ten larvae are dispersed into separate beakers marked for assorted concentrations. 500?g and 1000?g of sample is prepared utilizing methyl alcohol and 1 milliliter of each concentration is added to the corresponding beaker incorporating larvae and left for incubation at room temperature for 24 to 48 hours. 1 % methyl alcohol was used as control.2.3. Appraisal of Ph:Different concentration of methyl alcohol bark and nucleus wood infusion was prepared and pH was checked utilizing a pH metre.2.

4. Atomic soaking up spectrometry:Standards of lead, Zn and Cd were prepare at different concentration. The infusion was dissolved in concentrated sulfuric acid and filtered. The filterate was subjected to AAS along with criterions.2.5 Antimicrobial activity:Bacterial and fungous species were screened for different concentrations of bark and corewood methyl alcohol and aqueous infusions.


Plants are known to hold good curative effects documented in Traditional Indian System of Medicine [ 8, 9 ] . Though bioactivity of T.arjuna has been used in intervention of assorted nutriments since clip immemorial, their larvicidal and haemolytic activities were yet to be explored [ 10 ] . The present survey revealed that at 500mg concentration of methonolic infusion was able to demo important larvicidal belongings. This was more evident when the concentrations of infusion were increased and the same is tabulated ( Table 1 ) . The consequences obtained showed a clip and concentration/dose dependant in larvicidal activity which reveals aqueous infusion of both bark and nucleus wood were found to be 100 % lethal at 1000 milligram concentration.

A similar observation was reported in the earlier survey carried out on the same household [ 11, 12 ] .For haemolytic activity, even at the concentration of 1000mg both the works infusion methyl alcohol and aqueous were non able to lyse the RBCs. This consequence is besides in conformity with the old studies. [ 13, 14 ] .

( WHERE are th Discussion for the below consequences ) ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? Send me back with treatment. Name me as good! …

In instance of atomic soaking up spectroscopy the works showed absence of cadmium.lead was present merely in corewood aqueous infusion. Zinc was present in mild concentration.

Preferably corewood infusion showed maximal sum of Zn.The consequences of pH appraisal showed no drastic alterations in methyl alcohol and aqueous infusions of corewood and bark. ( Table the pH values )The antimicrobic activity of both, infusion at assorted concentrated did non demo any antimicrobic belongings. and consequences are tabulated ( Table 2 ) .

The survey concludes, methonolic infusions of T. Arjuna at minimal concentration of 500mg, was lethal for larvae and in-case of haemolytic belongings both the infusions were non-hemolytic doing them therapeutically safe for worlds. These checks have been carried out for other workss but non touched upon the nucleus wood and hence these were reperformed utilizing corewood.
