Terpenoids are important for normal growth and development. [28] A number of in vitro and limited in vivo studies shown that flavonoids such as quercetin have synergistic activity with antibiotics and are able to suppress bacterial loads.[29]. Biotransformation involving microorganisms and animal cells are described elsewhere. Elicitors are found to activate genes and increase the synthesis of mRNAs encoding enzymes responsible for the ultimate biosynthesis secondary metabolites. Plant cells can be cultivated in an aqueous two phase system for the production of secondary metabolites. Plants are capable of defending themselves when attacked by microorganisms, by producing antimicrobial compounds collectively referred to as phytoalexins. Elicitors produced within the plant cells are endogenous elicitors e.g., pectin, pectic acid, cellulose, other polysaccharides. These induce the production of secondary metabolites as a response to the stress. Eg., carbohydrates, vitamins, ethanol, lactic acid. It is a fact that many chemicals with complex structures that cannot be chemically synthesized can be conveniently produced in plants. Hence, terpenes are also termed as isoprenoid compounds. Secondary products are synthesized from primary metabolites. Inorganic phosphate is essential for photosynthesis and respiration (glycolysis). Some secondary metabolites, especially alkaloids, are toxic to prokaryotic and eukaryotic cells. Primary metabolites are compounds that are directly involved in the growth and development of a plant whereas secondary metabolites are compounds produced in other metabolic pathways that, although important, are not essential to the functioning of the plant. In addition, many secondary metabolites are produced through phosphorylated intermediates, which subsequently release the phosphate e.g., phenylpropanoids, terpenes, terpenoids.
