Chemosystematic significance of triterpenes from dichloromethane extracts of 28 Hieracium L. species from the Balkan Peninsula
Апстракт
The genus Hieracium L. s. str. (Cichorieae, Asteraceae) is one of the most taxonomically complex genera of flowering plants. Chemosystematic significance of triterpenes especially for Asteraceae genera is scarcely assessed. The subject of this research are 28 Hieracium species from Balkan Peninsula (mostly collected at Mt Durmitor, Montenegro): 12 principal belonging to sections Pannosa, Naegeliana, Drepanoidea and Villosa, and 16 hybridogenous originated from the species from those four sections and Glauciformia, Hieracium, Prenanthoidea and/or Italica. Previously, in dried dichloromethane extracts of flowering aerial plant parts, α-amyrin and α-amyrin acetate, as well as β-amyrin, β-amyrin acetate and/or lupeol acetate were identified and quantified using GC-FID-MS. The aim was to evaluate chemosystematic significance of these five triterpenes using multivariate statistical methods (principal components analysis-PCA and non-metric multidimensional scaling-nMDS). Statistical analysis ...supported the current taxonomical classification of the investigated species, despite overlapping of certain groups. In PCA, all five triterpenes significantly contributed to the differences between the species. Moreover, lupeol acetate could be a significant chemosystematic marker for the most of principal species belonging to the section Pannosa, as well as for some hybridogenous species between H. gymnocephalum Gris. ex Pant. and the members from the other sections.
