Abstract
All plants, during their metabolic activity, produce chemical compounds having medical utility. Itâs estimated that a minimum of 35,000 wild species possesses phytochemicals having therapeutic actions in humans and can be refined to produce drugs. Traditional Medicinal plants have been over-exploited for their antimicrobial activity for a long time, so we need to discover other alternative sources. Another widely and easily available but least important member/ category of the plant kingdom is weed. Weeds are considered a significant threat to major crops. Despite economic losses, many of these noxious weeds are naturally strong competitors and may provide a wide array of phytochemicals such as saponins, flavonoids, glycosides, tannins, alkaloids, and terpenoids. As weeds are inexpensive sources of material, developing cost-effective products from weeds could also be a way of choosing to manage the weeds. It could also help reduce the disturbance of weeds to other economic crops. A brief review of phytochemicals from weeds grow in Rajasthan, India is given below.
