In biotechnology has been concentrated to review alternative routes for the production of natural compounds. Plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. However, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

background & aim: turmeric, scientifically named (curcuma longa l.), a member of ginger (zingiberaceae) family, is a perennial plant, with pharmaceutical properties and with a rhizome. this plant has many medicinal characteristics including anti-cancer, anti-bacteria and anti-hepatitis properties. experimental: to study the effects of gibberellic acid and salicylic acid on leaf, the rhizome...

Plants are important source for the discovery of new products of medicinal value for drug development and plants secondary metabolites are unique sources for pharmaceuticals food additives, flavors and others industrial values. Commercial importance of these secondary metabolites has resulted in a great interest in its production and in exploring possibilities of enhancing its production by mea...

For millennia, secondary plant metabolites have antagonized microorganisms, insects and humans alike, ultimately generating a complex and dynamic mixture of facultative and obligate interactions from symbioses to pathogenicity. Secondary plant metabolites have an important role in developing the myriad of organic pollutant-degrading enzymes found in nature. The link between secondary plant meta...

This review outlines the antimicrobial activity of secondary metabolites and lectins, compounds usually associated to defense mechanisms of plants. Secondary metabolites are separated into nitrogen compounds (alkaloids, non-protein amino acids, amines, alcamides, cyanogenic glycosides and glucosinolates) and nonnitrogen compounds (monoterpenes, diterpenes, triterpenes, tetraterpenes, sesquiterp...

Plant secondary metabolites play significant roles in plant-environment interactions. Plant derived secondary metabolites are compounds that can be widely used in industry, medicine, food sciences etc. In this review, we summarize the research methods applied to analyse biosynthetic pathways of plant secondary metabolites. Moreover we present an up to date overview of the studies that were perf...

The high structural diversity of plant metabolites suggests that interactions among them should be common. We investigated the effects of single metabolites and combinations of plant metabolites on insect herbivores. In particular we studied the interacting effects of pyrrolizidine alkaloid (PAs), and chlorogenic acid (CGA), on a generalist herbivore, Frankliniella occidentalis. We studied both...
