In fact natural product once served as the source of all drugs. OcimumSanctumL. is an aromatic plant in the family Lamiaceae. The main chemical constituents of Tulsi are: Oleanolic acid, Ursolic acid, Rosmarinic acid, Eugenol, Carvacrol, Linalool, and β-caryophyllene, have been used extensively for many years in food products, perfumery, and dental and oral products. Recent studies suggest that Tulsi may be a COX-2 inhibitor, like many modern painkillers, due to its high concentration of eugenol. The present study was to evaluate the qualitative estimation of phytochemicals and antimicrobial activity ofaqueousand methanol extracts of root and leaves of Ocimum sanctumagainst pathogenic bacteria i.e. Escherichia coli, Proteus mirabilis, Staphylococcus aures.Study has been shownthe presence of steroids, alkaloids and tannins. Significant antimicrobial activity of plant extract has been observed.

Our future well-being depends on increased access to family planning and reproductive health services and decreased consumption by people. Family planning has been promoted through several methods of contraception. But due to series adverse effects produced by synthetic steroidal contraceptives, attention has now been given to indigenous plants for possible contraceptive effects. Thus there is a need of replace these agents by plants. The investigation of plant constituents with development of an effective, reversible and safe male contraceptive represents a potential alternative approach to birth control from the existing available methods. This review concentrates on those recent advances in science and technology that offer possible inroads for shifting the paradigm for male-based contraception. This review presents updated information gathered on scientifically proved medicinal plant (Withania Somnifera) and their more than 50 secondary metabolites might be can use as male contraceptive agents and other biological activity. The aim of this review is to highlight the work on various plant drugs and their bioactive extracts involved in male antifertility mechanism.

The size of nanoparticles is comparable to that of most of biological molecules (e.g., proteins, DNA) and structures (e.g., viruses and bacteria) therefore; nanoparticles can be developed for diagnostic devices, contrast agents, analytical tools, physical therapy applications, and drug delivery vehicles. This review illustrates possibilities of development of reliable experimental protocols for the bio synthesis of nanomaterial's using different plant extracts by performing analytical comparisons of characterization techniques like Ultra Violet visible spectroscopy, Scanning Electron Microscope, Transmission Electron Microscope and X methods of synthesis have paved way for the "greener synthesis" of nanoparticles and these have proven to be better methods due to slower kinetics, being environmentally friendly, less expensive. Also they offer better manipulation and control over stabilization of nanoparticles.
