INTROdUCTION
The thyroid is a small butterfly-shaped gland is positioned in front of neck, just below the voice box (larynx). This gland plays a completely important role in controlling our frame metabolism i.e The rate at which our frame uses electricity and it does this through producing thyroid hormones like thyroxin or T4 and Triode thyronine or T3, chemical compounds that travel through our blood to every components of our body. It produces chemical compounds that help the frame to control metabolism. Thyroid hormone is commonly produced in response to every other hormone launched via the pituitary gland. 1 Generally, thyroid troubles are grouped in two most important classes i.e Hyperthyroidism (too much thyroid hormone) and hypothyroidism, (too little thyroid hormone) right here we discuss approximately hypothyroidism, the most not unusual signs of hypothyroidism includes fatigue, depression, constipation, weight advantage, gradual coronary heart rate and so forth. Medicinal plants are the richest bio-resources of medication for classic device of medicine. Flax seeds (Linum usitastassimum L) is a multipurpose crop and its intake is beneficial for fitness. 2 Flax seeds is a wealthy supply of healthy fats, antioxidant and fibre.
The nutrient in flax seeds may additionally assist decrease danger of diabetes, most cancers, heart ailment and thyroid 3 . Flax seeds is one of the oldest vegetation, having been cultivated due to the fact the beginning of civilization. The Latin name of the flax seed is Linum usitatissimum, which means very beneficial. Flax seed is one of the high content of omega-three fatty acids ie. Alpha linolinic acid (ALA) 4 and liganans (phytoestrogens).
The crucial flax seeds developing international locations are Canada, China, U.S, India and Ethiopia.
Flax seeds has potential health benefits besides the nutrition, due to mainly three reason; Firstly due to rich source of omega-3-linolenic acid. Secondly being rich in dietary soluble and insoluble fibres and third, due to its high contents of liganins, acting as antioxidants, phytoestrogens 5 . The healthy use of all the three omega-3 fatty acids have been mostly indicated in several conditions like cardiac diseases, hypertension, diabetic condition osteoporosis and in many autoimmune conditions and neurological disorders 6 . The medicinal importance of a plant is due to the presence of some specific material like alkaloids, glycosides, resins, volatile oil, gum and tannins etc. Considering all these valuable points the present study is designed to investigate the presence of various phytochemicals in the flax seeds 7 . In todays condition AgNO 3 can be prepared by different methods like biologically or chemically. These nanoparticle are of prominent use in many fields like industrial, pharmaceutical, and medicinal field.
In the present work, the silver nanoparticles were prepared from the flax seeds extract and it is characterized by UV-Vis spectroscopy, Sem analysis with EDX and FTIR analysis.

Collection of seeds
The seeds of flax were accumulated from local market of Bilaspur (C.G) India.

Extraction of seeds oil
The seeds were nicely wiped clean and air dried. The dried sample had been then powdered with the assist of house keep grinder. The powdered pattern became stored in an air tight box. Extraction of seeds oil is accomplished by using using sohxlet apparatus the use of petroleum ether as solvent. The extract obtained become gathered and filter via Wattmann No.1 clear out paper to take away alldebris and unextracted count number. Filtered extract become concentrated the usage of rotatary evaporator at 40 diploma centigrade to acquire focused extract 8 .

Phytochemical screening of Flax seeds
Qualitative and quantitative evaluation of flax seeds were finished by way of using general strategies.

In case of flax seeds unique cellular solvent gadget have been taken for Preparing take a look at :-According to Harborne 10 by means of the usage of to separation solvent and the lignan was appeared as dark spot on TLC plate as shown in Fig. 1. Various separation solutions like (ethyl acetate: Water) in ratio (1:19) and (Benzene: Methanol) in ratio (1:9). The dark spot has Rf: 0.45 and this Rf value is equal to Rf value of lignin, according to Harborn [7], when used the liquid-liquid system to separate the lignan from flaxseed. The ethyl acetate: water system has weak polarity and the lignan is soluble in water and when we evaporate water yellowish powder is obtained 13

Nanosynthesis
In present world, nanotechnology a moderately new field, Nano, a logical word is utilized for deciding the size of the molecule 14 Nanosynthesis, an idea in the field of research and innovation, lately, has likewise been probably going to become dependent on their interest, as different advances.
Nanoparticles are normally a bunch of atoms running between 1-100 nm in and they display new properties dependent on their size, conveyance & morphology 15 . Numerous materials are combined in nano size for different uses including medical field, scientist in the field of nanotechnology are finding that metals nanoparticles have a wide range of surprising advantages. They are normally set up by honorable metals, that is, Ag, Au, pt and pd while silver nanoparticles (AgNPs) are mostly exploited 16 due to its more extensive scope of use in medication, hardware, energy saving, climate, material, beautifiers, biomedical, and so forth.

Preparation of aq.AgNO 3
AgNO 3 solution (1 mM) is prepared and saved in dark coloured bottles.

Synthesis of AgNPs
Seeds extract of 1 to 5 mL have been taken separately and in this extract 10 mL of 1 mM AgNO 3 solution become delivered with steady stirring and exposed to one of a kind situations like sunlight irradiation, UV-irradiation.The colour change of the solution was periodically checked. The colour exchange of the seed extract from light yellow to dark brown indicates that the AgNPs have been prepared from seeds extract. This nanoparticle extract are subjected to centrifugation at 10,000 rpm for 15 minute. The pellet prepared were treated with 0.1 mL of toluene H 2 O and dried in air.

Characterisation of silver nano particles Uv-spectrophotometer

CONCLUSION
The conducted studies concluded that the presence of various secondary metabolites in flaxseeds extract having medicinal properties and because of their natural properties and enhance qualities by nanosynthesis. It will be beneficial to supplement other medical treatment with natural herbs for underactive thyroids. The conducted studies confirms the presence of functional group that form the part of active compounds of flax seeds which have medicinal properties and can be used as antithyroid agents. Flax seeds extract consist of oil in abundance. The active compound in flax seeds is called Omega -3-fatty acids i.e. Alpha linolinic acid has the power to influence thyroid function and improve the condition of hypothyroidism. It has been reported that the consumption of Omega -3dietery supplements leads to significant reduction of non steroidal anti inflammatory drugs. 19 Studies have shown that the high intake of dietery fibers is beneficial of obesity in both men and women. 20 An advantage of this herb is decrease the level of harmful cholesterol which is due to high weight gain and which is one of the feature of hypothyroidism.
