**4. Conclusions and future prospects**

In spite of bottlenecks in the large scale production of phytopharmaceuticals many technological advancements and refinements have been made in the recent years right from the selection of high yielding cell lines to manipulation of basic chemical, physical and biological parameters. The identification of right explant of proper developmental stage, standardization of optimum nutrient medium resulting in maximum accumulation of pharmaceuticals, optimization of low-cost production technology are some of the areas which warrant immediate attention. Knowledge of the biosynthetic pathways of desired compounds in plants as well as *Production of Medicinal Compounds from Endangered and Commercially Important Medicinal… DOI: http://dx.doi.org/10.5772/intechopen.90742*

in cell cultures is still rudimentary, therefore emphasis need to be made generate information based on a cellular and molecular level. Major breakthrough in the metabolomics and its integration with genomics and transcriptomics technologies will help in discovering potential genes of biosynthetic pathways so that closer understanding of the links between different levels in biological systems can lead to better understanding of the molecular biology of secondary metabolite production in plants.
