Nanotechnology refers to the technique of making ultra-small particles; it is expected to gain a lot of popularity in the medical field. Ultra-small particles should find less resistance getting through biological barriers like surface epithelium of the skin, intra luminal epithelium of the guts and special compartment like the brain which is protected by a special "bloodbrain barrier". Indeed nanotechnology is offering services in many areas of innovation in drug delivery. Medicinal plants in common use are those that possess long historical records of pragmatic clinical applications, hence they are assumed to be effective and safe. Medicinal plants have shown that nanotechnology could offer new solutions in the quality control and delivery aspects of herbal compounds. Pharmaceutical drugs are in possession of clear chemical identities which ensure straightforward quality controls. Nanotechnology is partly built on the principles of solubility of chemicals which can be manipulated to yield a product from a variety of solvents, containing the desirable concentration or quantity of bioactive ingredients. Such chemical engineering technique is going to overcome difficulties in obtaining uniform bioactive extractions from medicinal plant. Some species like Pseudomonas, klebsialla, Acenatobactor, E.coli, Proteus, Candida, Staphylococcus show antimicrobial activities against Petroleum ether extract. These species are treated with silver and gold nanoparticles in Vitex Trifolia medicinal plant extract. Different solvent Extraction procedure prepares extract of phytochemicals. These phytochemicals are use to detect carbohydrate, protein flavonoids terpenoids tannins. These are present in plant extract in markable amount. Bioactive compound of medicinal plant extract shows high antimicrobial activity against different disease causing microbes.
