Abstract ___________________________________________________________________________________________________________________ Hyperglycemia is indeed a dyslipidemia across a Globe. An International Diabetes Federation (IDF) has Predicted a certain 366 million more people have diabetes in 2011 and it has been raised up to 552 million by 2050. It approximated a certain 40 million people of hyperglycemia through India in 2007 and yet this may predicted to grow almost to 70 million affected by 2025. LD50 study of the ethanolic extract of S. emarginatus seed kernel (EESESK) has been done throughout Albino rats up to a daily dosage constrain of 2000 mg/kg orally (according to OECD guidelines No.425 of CPCSEA) 1/5th, 1/10th dosage as from maximum dose examined for LD50 study results were again for experimental test research to examine a impact of S. emarginatus for a anti diabetes action. Insulin inefficiency was found in two selected model for my study. Alloxan hydrate at such a mg dosage of 150 mg/kg i.p after 48 hrs, the EESESK seed kernel it at a dosage of 200 mg/kg but also 400 mg/kg p.o have been administered. Dexamethasone 10 mg/kg, i.p, once daily. And at the inter of 30 mins EESESK 200 mg/kg and 400 mg/kg p.o had been conducted in rats for a period of 11 and 21 days respectively. At the end of the experimental, serum biomarkers such as glycogen, high cholesterol, triglycerides, LDL, HDL, and VLDL were analyzed by using semi-auto analyzer. In both models EESESK at a dose of 400 mg/kg exhibited substantial impact. Alloxan hydrate increased serum biochemical markers like glucose, high cholesterol, triglyceides, LDL, VLDL levels but decreased HDL levels. Dexamethasone caused an increase in serum glucose, High cholesterol and reduces High density lipopretein-cholesterol levels. The present study indicates that S.emarginatus seed kernel useful for the management of diabetes mellitus. S.emarginatus pollen seed found important reducing of glycogen TC, TG, LDL, VLDL levels and increased level of High Density Lipoprotein through diabetic concept mice. A enhanced high density lipoprotein is also Cardioprotective activity. Therefore S.emarginatus seed kernel must have future role to forestall forming of atherosclerosis but also cardiovascular disease.

INTRODUCTION
Indian national Diabetes Federation (IDF) pronounced Hyperglycemia must have popped up as one of the severe medical concern and this is estimated 40 million persons were affected of hyperglycemia through India in 2007 and yet this total count may rise to 70 million besides 2025. Regions with huge population of diabetics could be India, China, USA, through 2030. That is predicted that every 5th person would be of diabetic patient will be an India. The genuine hardship of such illness is indeed because of the associated complications where it leads to higher mortality and morbidity 1. WHO estimated that mortality through the hyperglycemia. Cardiovascular diseases expenses most of $210 billion through india in year 2005. Most of the cardiovascular diseases within those researchers estimate were associated a globe like hyperglycemia between adult people (aged 20-79 years) would be 6.4% impacting 285 million adult people through 2010 which will enhance to 7.7%, among 439 million adult people through 2030. Among 2010 as well as 2030, there would be a 69% enhance percentages like older adults through developing nations as well as 20% raise through developed nations. To Study the protective influence like ethanolic extract of seed kernel of S.emarginatus against morphological changes (Body Weight) Induced by Alloxan monohydrate and Dexamethasone 2.

Plant Material
Soap nut seed kernel: 500 gms soap nut seed kernel was used in this study, 21 gms of soap nut seed kernel extract were obtained. The soap nuts were collected from the local market of jagannadhapuram in Andhrapradesh (India).
Test drug: Sapindus emarginatus seed kernel (200 mg/kg+400 mg/kg/p.o)
Inducers: Dexamethasone10 mg/kg i.p, Alloxan hydrate150 mg/kg i.p
Animals: wistar albino rats weighing 120-250 gm.
Biochemical Kits:
Glucose kit (GOD/POD method)
Source: Crest Biosystems, A Division of Coral Clinical Systems, Goa.
Principle
Glucose is oxidized to gluconic acid and hydrogen peroxide in the presence of glucose oxidase. Hydrogen peroxide further reacts with phenol and 4-aminoantipyrine by the catalytic action of peroxidase to form a red colored quinoneimine dye complex. Intensity of the color formed is directly proportional to the amount of glucose present in the sample 5.
Triglycerides kit (GPO/PAP method)
Source: Crest Biosystems, A Division of Coral Clinical Systems, Goa.
Principle
Lipoprotein lipase hydrolyses triglycerides to glycerol and free fatty acids. The glycerol formed with ATP in the presence of glycerol kinase forms glycerol 3 phosphates which are oxidized by the enzyme glycerol phosphate oxidase to form hydrogen peroxide. The hydrogen peroxide further reacts with phenolic compounds and 4 aminoantipyrine by the catalytic action of peroxidase to form quinoneimine dye complex. Intensity of the color formed is directly proportional to the amount of triglycerides present in the sample 6.
Cholesterol kit (CHOD/PAP method)
Source: Crest Biosystems, A Division of Coral Clinical Systems, Goa.
Principle
Cholesterol esterase hydrolyses esterified cholesterol to free cholesterol. The free cholesterol is oxidized to form hydrogen peroxide which further reacts with phenol and aminoantipyrine by the catalytic action of peroxidase to form quinoneimine dye complex. Intensity of the color formed is directly proportional to the amount of Cholesterol present in the sample 7.
Extraction procedure
Drying and size reduction
Soap nut seed kernel was subjected to drying in normal environmental condition under shade. The dried seed kernel was powdered by the help of a hand mill and was stored in air tight container. The powdered material was passed through sieve of 16 mesh size to obtain uniform particle size for extraction 8.
Extraction process
Harvesting has been the common process for detachment of active components with the use of ethanol solvents. A solidified dry powder plants is usually use it for harvesting. Harvesting alone might remain executed through reproduced maceration of agitation percolation or through ongoing harvesting through soxhlet extraction.
The soap nut seed kernels were powdered by the help of a hand mill. The powder was sieved by No.16 mesh. 500 g of powder was defatted with petroleum ether at 50-60°C for 24 hr. After 24 hr the dry defatted powder was poured into the soxhlet apparatus. Sufficient solvent (90% ethanol) was added into the flask and the soxhlet apparatus was placed on the mantle along with 3-4 ceramic chips. The flask was fitted with a water-cooled condenser. The mantle was switched on and the temperature was set at 45°C.The extraction was continued for 36 h, 1-2 cycles per hour. After 36 h the mantle was switched off and water flow was stopped. After cooling the plant material was removed by filtration through a cotton plug. The solvent of the extract was evaporated by using normal distillation. The concentrated mass was taken in a porcelain disc and evaporated in a water bath at 55°C. Then it was left at room temperature to get a dried mass of the extract. The extract mass was weighed in a digital balance. The extract was labeled and kept in freeze for further use 9.

Preliminary Phytochemical investigation
The methanolic extract obtained from the above extraction processes was analyzed for different phytoconstituents present in this by the method of qualitative phytochemical analysis 10.
Tests for Alkaloids
Mayer’s Test
This is other method for identifying alkaloids. To organize a titrant, 1.36gm of mercuric chloride has been disintegrated through deionised water. In that other portion disintegrate 5gm of potassium iodide through 60 ml of deionised water. However both its portions have been combined and also the quantity has been modified to 200ml. With alkaloids this has shown white to buff crystalline 11.
Dragendroff’s Test
With alkaloids all these titrant provides orange-brown colored precipitate. To organize the above titrant, 14gm like sodium iodide has been steamed as for 5.2gm like bismuth carbonate through 50ml glacial acetic acid only for a few mins. Then that was allowed to exist for up to overnight and indeed the crystalline like sodium acetate has been filtrated beyond. To 40 ml of filtration 160 ml of acetate and 1 ml of water will be added. A stock solution has been saved through amber-colored bottle. Throughout research; to 10 ml of stock solution 20 ml of acetic acid was added as well as the final volume has been made up to 100 ml with water 12.
Hager’s Test: All these titrant has shown characteristic crystallization precipitate with several precipitates. Inside this instance a saturated aqueous picric acid would be used for recognition of alkaloids 13.
Tests for Carbohydrates
Benedict’s Test: Inside this approach to assess for monosaccharide, 5 ml of Benedict’s reagent and 3 ml of test solution while steamed on even a steam bath as well as brick red crystalline has seemed there at lower half of a test tube affirms a existence of such substances 14.
Fehling’s Test: Inside this method 2 ml of Fehling ‘A’, 2 ml like Fehling ‘B’ and 2 ml of extricate seem to be heated. The presence of reducing fructose has been affirmed. Whether the yellow or brick red crystalline does seem just at lower half of a test tube affirms that whole existence of a monosaccharide 15.
Molisch’s Test: When the aqueous or alcoholic solution of the extract and 10% alcoholic solution of α-napthol had been shaken but also concentrated Sulphuric acid has been added all along side of the test tube, a violet ring now at junction of the two fluids affirms existence like dietary carbohydrate 16.
Test for Anthraquinone Glycosides
Borntrager’s test: The 0.1gm of a powder form substance has been heated as for 5 ml of 10% sulphuric acid for two minute. This was filtrated while warm, Then allowed to cool and also the filtration has been shaken with average volume like benzene. The benzene sheet has been permitted to totally separate fully as from lower layer, Which has been pipette out again and transmitted over to a clean test tube. Whereupon half to separate. The lower ammonia layer will show red pink color 17.
Tests for Gums And Mucilages
Molisch’s Test: Among its quantity of aqueous solution of a extricate but also 10% alcoholic solution of α-napthol seem to be shaken and concentrated Sulphuric acid was added all along side of the test tube, a violet ring at the junction of the two fluids affirms existence of carbohydrates, gums as well as mucilage 18.
Tests for Proteins and Amino Acids
Biuret Test: When 2ml ofa extricate, 2 ml of 10% NaOH solution and 2-3 drops of 1% CuSO4 solution had been combined, the looks of violet or purple color affirms a existence of proteins 19.
Ninhydrin Test
When 0.5 ml of ninhydrin solution is added to 2 ml of the extract and boiled for 2 minute and then cooled. The appearance of blue color confirms the presence of proteins 20.
Tests for Tannins and Phenolic Compounds
Lead Acetate: Tannins get precipitate with lead acetate.
Ferric Chloride: Generally phenols were precipitated with 5% w/v solution of ferric chloride in 90% alcohol and thus phenols are detected 21.
Tests for Triterpenoids
Tin and Thionyl Chloride: For detection of triterpenoids the extract was dissolved in chloroform. A piece of metallic tin and 1 drop of thionyl chloride was added to it. Pink color confirms the result 22.
Tests for Saponins
Foam Test: About 1 ml of alcoholic and aqueous extract has been diluted individually with deionised water to create the quantity up to 10 ml, and shaken inside a graduated cylinder for 15 minutes but also retained aside. 1 cm layer of foam after hanging for 30 minutes suggests the existence of saponins 22.
Tests for Flavonoids
Test with NaOH: Again for identification of flavonoids, the extricate has been first dispersed to liquid. This has been filtrated and also the filtrate has been allowed to treat with sodium hydroxide. A yellow color affirms the existence of flavonoids 23.
Shinoda test: The limited amount of sample has been taken inside a test tube as wll as dispersed through methanol (1 ml). A pinch of magnesium powder has been added followed besides concentrated. Hydrochloride. Appearances of pink color identify the existence of flavonoids, bioflavonoid 20.

Effect of EESKSE on Dexamethasone induced diabetes in rats
Biochemical parameters in normal control rats
The normal group of rats the blood glucose levels, TC and HDL are found to be 76.65±1.05 mg/dL, 76.92 ±0.55 mg/dL and 68.95 ±1.40 mg/dL respectively.
Effect of Dexamethasone (150 mg/kg) on biochemical parameters in rats
When compared to normal control group of animals, the biochemical parameters such as Glucose (207.58±1.01 mg/dL), TC (169.22±1.01 mg/dL) are significantly increased, whereas HDL (30.69±1.30 mg/dL) levels are significantly decreased [Table 8].
Effect of Glibenclamide (5mg/kg) on biochemical parameters of Dexamethasone induced diabetes in rats
When compared to normal control animals the biochemical parameters such as Glucose (107.15±0.75 mg/dL), TC (100.62±1.29 mg/dL) are significantly decreased, whereas HDL (56.92±1.55 mg/dL) levels are significantly increased when compared to toxicant group [Table 9].
Effect of EESKSE 200 mg/kg on biochemical parameters of Dexamethasone induced diabetes in rats
When compared to normal control animals the biochemical parameters such as Glucose (147.12±1.09 mg/dL), TC (108.40±0.81 mg/dL), are significantly decreased, whereas HDL (61.45±1.01 mg/dL) levels are significantly increased when compared toxicant group [Table 10].
Effect of EESKSE (400 mg/kg) on biochemical parameters of Dexamethasone induced diabetes in rats
When compared to normal control animals the biochemical parameters such as Glucose (68.70±0.76 mg/dL), TC (67.81±0.71 mg/dL) are significantly decreased, whereas HDL (66.98±1.28 mg/dL) levels are significantly increased [Table 11, 12 & 13].
Physical Parameters
Body Weight
The body weight of the normal and treated groups significantly difference from the diabetic control on 11th day. The treated groups animal body weight maintained throught the experiment compare to diabetic control.

EESESK: Ethanolic extract of seed kernel of S.emarginatus
CONCLUSION
The present study indicates that S. emarginatus seed kernel is used for the management of diabetes mellitus. S. emarginatus seed kernel showed significant reduction of Glucose, TC, TG, LDL, VLDL levels and increased level of HDL in diabetic model rats. The increased HDL is also cardio protective activity. Therefore S. emarginatus seed kernel has potential role to prevent formation of atherosclerosis and coronary heart disease.
