Biotechnological and chemo diversity approaches of Plant secondary metabolites

Plant secondary metabolites are evaluated as strong potential for biotechnologicalapplications. Plants are well known of arsenal chemical defense against pathogens, herbivoresand pests. Theses active compounds are chemically diverse and categorized according to theirstructures reflecting wide spectrum of phyto-chemicals. Among the most active compoundsproduced by plants are: alkaloids, essential oils, flavonoids, glucosinolates and phenols.Although these compounds are used by plants in their ecological interactions, however;secondary compounds are used as major sources of alternative medicines, bio-pesticides, foodadditives or in cosmetic industry. These benefits can be achieved through biotechnologicalapproaches for example plant tissue culture and genetic engineering.
