My present research is focusing on the evolution of plant secondary metabolites within a particular group of plants of medicinal importance. I have gone through a review of Wink which I am enclosing. As we all know, this phenomenon occurs because of convergent evolution. But to establish it in a scientific manner how should I proceed. Any constructive opinion is most welcome.
Dear Christian thanks for your input, but I want to relate the phylogenetic evolution with the chemical entity also using chromatographic methodologies like HPLC/RHPLC/LC-MS/GC-MS. In that review it is mentioned but how will i proceed. Thats my main query.
Do you want to know how to gather data on secondary metabolites, or to understand the evolution of secondary metabolites once you have the data? If the latter, then you would use programmes like Mesquite to reconstruct ancestral states, from which you would infer evolutionary patterns, as pointed out by Cristian.
Dear Geeta mam, actually I want to study the evolution of a particular molecule or two suppose Ginseng is an active compound present in the genus panax. Now mam panax has got 5 species. I want to study how this ginex is evolving (qualitatively and quantitatively) with phylogeny. I went through a review article of wink which already I have enclosed but still about the procedure to do so I am confused actually mam.
Get in touch with Vicki Funk at the Smithsonian - she was the first phylogeneticist to approach this problem - begin your literature review with
Seaman, F. C. and V. A. Funk. 1983. Cladistic analysis of complex natural products: developing transformation series from sesquiterpene lactone data. Taxon 32: 1-27.
