Description :
The present study reports about the presence of phytochemical constituents of aqueous extracts prepared from eight common and noxious allelopathic weeds belonging to seven families collected from13 different Tahasils in Pune district of Maharashtra, India. Histochemical studies and qualitative phytochemical analysis were performed by using fresh healthy plant parts and extracts of the weeds for the presence of starch, proteins, tannins, saponins, fat, sugars, alkaloids, and glycosides. For the histochemical studies free hand cut sections about 20-25 of the root, stem and leaves of selected weeds were taken and tested with respective reagents for the detection and localization of chemical constituents. Each phytochemical analysis was carried out in duplicate, which resulted in a total of species of 4, 6, 4, 8, 7, 1, 8, 2 and 8 plant species were found positive results for Starch (50%), Proteins (75%), Tannins (50%), Saponins (100%), Fat (87%), Anthraquinones (12%), Alkaloids (100%), Flavonoids (25%) and Glycosides (100%) respectively. Most of the plants studied were reported to treat a variety of diseases in traditional system of medicine.
