[Components of Serratula species; screening for ecdysteroid and inorganic constituents of some Serratula plants].
Ecdysteroid and inorganic components were analyzed from several plant species belonging to Caryophyllaceae family, such as in the cases of Serratula tinctoria, Serratula wolffii, Serratula coronata (20-hydroxyecdysone and inorganic components) and Jurinea mollis, Serratula gmellinii and Leuzea carthamoides (inorganic components, only). The 20-hydroxyecdysone content was determined using thin-layer chromatography after a simple clean up that had been performed by solid-phase extraction. Inorganic constitutents were determined using either ICP or flame photometry. Vegetation dependence of both 20-hydroxyecdysone and inorganic elements was studied. Serratula coronata shows remarkable high 20-hydroxyecdysone (2.3%, in April) and the studied Serratula plants gave a minimum of 20-hydroxyecdysone in June. Favorable period for harvesting is suggested as July and August, through the blossoming of these plants. Potassium and 20-hydroxyecdysone content gave a similar tendency considering their vegetation dependence, while the magnesium content moved toward opposite direction. The calcium contents of Serratula tinctoria, Serratula wolffii and Serratula coronata were found between 2.2% and 3.8%, which values are high relative to the other medicinal plants. At the same time, the Cu content of the ecdysteroid producing (and screened) Caryophyllaceae plants is low. The Fe, Mn and Mg contents of Serratula coronata are high, even higher than that of the Leuzea carthamoides. Our results have suggested the importance of analysis and control of inorganic constituents of crude plant extracts used for medicinal and recreational purposes.
