Recent Advancements on Callus and Cell Suspension Cultures: An Effectual Reserve for the Production of Pharmaceutically Significant Metabolites

Secondary metabolites of pharmaceutically importance or phytopharmaceuticals comprise alkaloids, glycosides, flavonoids, volatile oils, tannins, resins etc. At present, most of these secondary metabolites are extracted from wild or cultivated plants since their chemical synthesis is either tremendously tough or economically impracticable. Production through callus and cell suspension cultures is a gorgeous substitute, nevertheless till yet this has had only restricted marketable accomplishment owing to less-existence of empathetic of how these metabolites are synthesized. The current book chapter has summarized some of the current progresses and investigations conducted by authors for the production of some of the useful bioactive secondary metabolites viz., withanolides, bacosides, glychyrhizin, reserpine, ajmalicine, amarogentin, plumbagin and terpenoids from callus and cell suspension cultures of corresponding plant species. The similar have been deliberated vastly.
