Abstract Bioactive alkaloids, glycosides and saponins are phytoconstituents and belong to the secondary metabolites of plants kingdom. These constituents possesses many pharmacological properties such as antioxidant activity, antimicrobial effect, modulation of detoxification of enzymes and hormone metabolism, stimulation of the immune system, decrease of platelet aggregation procedure, possess antidiabetic, antihypertensive, antidepressants, analgesics and anticancer etc. properties. Now a days these compounds have received great attention worldwide as the sources of novel agents, important pharmaceutical intermediates and significant starting materials for a lot of synthetics or semi synthetics drugs due to potent pharmacological activities, higher safety profile, low toxicity and cost effectiveness. So the current study is designed to focus on the accumulation of sufficient information’s about the above mentioned phytoconstituents regarding their pharmacological effects and mechanisms of action along with other significant properties.
