Background: AIDS in humans, which is caused by the HIV remains among the leading causes of death worldwide. Objective: The study was undertaken to investigate the HIV-RT inhibitory activity of Phytotesrols extracted from roots of Aerva lanata. Methodology: Sequential maceration method was performed for preparation of extracts using hexane, chloroform, ethyl acetate, acetone and methanol solvents. RetroSys HIV-1 RT (Innovagen, Sweden) kit was used to determine the HIV-RT inhibitory activity of all solvents extracts. Results \& Discussion:\ All extracts showed significant inhibitory activity. Chloroform extracts shows highest inhibition of recombinant HIV-RT (89.0\%) at 2 and mg/ml concentration. Phytosterols isolated from chloroform extracts. These results were remarkable and can be used to develop a new drug for HIV treatment or other infectious diseases caused by the pathogenic micro-organisms, for which plant sterols may play a distinctive role. Conclusion: Further work is in progress to evaluate the advanced spectroscopic studies are required for the structural elucidation, identification and characterization of the active compound from this plant.

Background:Aerva lanata is an interesting plant used in traditional medicine for many years and used for the treatment of bladder and kidney stones. Objective: The aim was to study detailed pharmacognostic profi le of an important medicinal plant in the Indian system of medicine, A. lanata (amaranthaceae). Materials and Methods: Flower samples of A. lanata were studied by macroscopical, microscopical characters. Physicochemical, phytochemical, and fl uorescence analysis of powder of the plant was performed according to the methods of standardization recommended by World Health Organization. Results: Macroscopically flowers are small, actinomorphic, and solitary or aggregated in cymes. Microscopically ovary was found to be bicarpellary, syncarpous, unilocular, superior; ovules one to many and campylotropous type. Powder microscopy of fl ower revealed the presence of epidermis with stomata and covering trichomes, calcium oxalate crystals, starch grains, and oil globules. The investigations also included fl uorescence analysis. Physiochemical parameters such as total ash, acid insoluble ash sulfated ash and water soluble ash; moisture content values were found to be 12.66\%, 1.64\%, 9.12\%, 4.52\%, 12\%, respectively. Preliminary phytochemical screening showed the presence of carbohydrates, triterpenoids, fl avonoids, glycosides, and phenolic compounds. Conclusion: The results of the present study can serve as a valuable source of information and provide suitable standards for identifi cation of this plant material in future investigations and applications.
