Abstract
A large number of medicinal plants are explored from the natural flora for the production of commercial drugs. The past few decades have seen increasing scientific interest in both growth of plant tissue culture and the commercial development of this technology as means of producing valuable phytochemicals. The most important of these bioactive constituents of plants are alkaloids, tannins, terpenoids, saponins, quinones, flavonoids, steroids, cardiac glycosides, oils and phenolic compounds. This review also covers the different methods of qualitative phytochemical analysis and revealed the phytochemicals used with different phytohormone combinations of tissue culture medium in some medicinal plants calli. Phyto pharmacological screening of medicinal plants and their extracts will reveal their presence of valuable compounds and provide insight into new ways of treatment with new drugs. Phytochemical constituents are the basic source for the establishment of several pharmaceutical industries.
