Regularities of saponins and ecdysteroids distribution in plants: chemotaxonomical and molecular phylogenic approaches

With the use of chemotaxomomical and molecular-phylogenetic approaches distribution of steroid and triterpenic glycosides in family Fabaceae Lindl. and ecdysteroids in family Asteraceae is studied. It is established, that the majority of representatives family Fabaceae contain triterpenic glycosides, steroid glycosites are found out only in the some phylogenetic isolated taxons in tribes Loteae, Thermopsideae and Trifolieae. Existing phylogenetic communications between kinds of family Asteraceae are revealed, at which ecdysteroids, probably, carry out an ecological role. Scientifically proved forecast of search the resource kinds of plants - producers of secondary metabolites of mevalonant ways of saponines and ecdysteroids biosynthesis are developed.
