“…Doronicum türlerinin topraküstü kısımları ve kök ekstrelerinin pirolizidin alkaloidleri, flavonoitler, terpenler (timol türevleri) ve benzofuranlar (tremeton türevleri) gibi bileşikler içerdiği birçok çalışma ile gösterilmiştir. Tiyofen türevleri ve kumarinler de bazı türlerde bulunmuştur [133,145,146,[149][150][151][152][153][154][155][156][157][158][159][160][161][162][163][164][165][166][167]. Uçucu yağı ise seskiterpenler ve monoterpenler bakımından zengindir [142,[168][169][170][171].…”

“…It is quite interesting to evidence the presence of tremetone derivatives ( 32 – 42 ) in D. austriacum , [11–12] D. hungaricum , [19] D. macrophyllum [21] and D. pardalianches [20] and of pyrrolyzidine alkaloids ( 70 – 73 ) in D. columnae [14] and D. macrophyllum ( Figure 3). [22] …”

“…Some of the most common PAs are floridanine ( 70 ) otosenine ( 72 ), senkirkine ( 73 ) and doronine ( 71 ) ( Figure 3), that have been identified in some Doronicum taxa ( Table 2). The last one, with chemical structure of 6′‐chlorodeoxyfloridanine, identified in 1976, took its name from Doronicum macrophyllum , the species from which it was isolated for the first time [22] …”

“…(+)-Doronine,* a Cl-containing secopyrrolizidine alkaloid first isolated by Russian workers from Doronicum macrophyllum (Alieva, Abdullaev, Telezhenetskaya & Yunosov, 1976) was isolated from the methanol extract of Senecio clevelandii E. L. Greene. The physiological properties of seco-pyrrolizidine alkaloids have not been extensively in-*Systematic name (Chemical Abstracts) : (15~t,20R)-12-acetoxy-20-chloro-15,20-dihydro-15-hydroxy-4-methyl-4,8"secosenecionan-8,11,16-trione. 0108-2701/84/010163-04501.50 vestigated (Culvenor, 1976).…”

“…Furthermore, it has been proposed that the intramolecular N...C=O interaction in the structure may be relevant to the physiological activity of pyrrolizidine alkaloids (Bfirgi, Dunitz & Shefter, 1973). The structure (I) (empirical formula C21H30CINO 8) based on spectral and chemical data (Alieva et al, 1976) was ascribed to (+)-doronine. The present X-ray analysis was undertaken to determine the configuration at all the chiral centers.…”
