AB  - The genus Senecio (family Asteraceae) is one of the largest in the world. It comprises about 1100 species which are the rich source of pyrrolizidine alkaloids. Plants containing pyrrolizidine alkaloids are among the most important sources of human and animal exposure to plant toxins and carcinogens. The pyrrolizidine alkaloids of seven Senecio species (S. erucifolius, S. othonnae, S. wagneri, S. subalpinus, S. carpathicus, S. paludosus and S. rupestris) were studied. Fourteen alkaloids were isolated and their structures determined from spectroscopic data (1H- and 13C-NMR, IR and MS). Five of them were identified in S. erucifolius, four in S. othonnae, two in S. wagneri, four in S. subalpinus, two in S. carpathicus, three in S. paludosus and three in S. rupestris. Seven pyrrolizidine alkaloids were found for the first time in particular species. The results have chemotaxonomic importance. The cytotoxic activity and antimicrobial activity of some alkaloids were also studied.
AB  - Jedan od najbrojnijih rodova na svetu je rod Senecio (familija Asteraceae). Obuhvata oko 1100 vrsta koje predstavljaju bogat izvor pirolizidinskih alkaloida. Najznačajnija izloženost ljudi i životinja biljnim toksinima i karcinogenima potiče od biljaka koje sadrže pirolizidinske alkaloide. U ovom radu izolovani su pirolizidinski alkaloidi iz sedam vrsta roda Senecio (S. erucifolius, S. othonnae, S. wagneri, S. subalpinus, S. carpathicus, S. paludosus i S. rupestris), a njihove strukture određene na bazi spektroskopskih podataka (1H- i 13C-NMR, IR i MS). Izolovano je ukupno 14 alkaloida, pet iz S. erucifolius, četiri iz S. othonnae, dva iz S. wagneri, četiri iz S. subalpinus, dva iz S. carpathicus, tri iz S. paludosus i tri iz S. rupestris. Sedam pirolizidinskih alkaloida je po prvi put izolovano iz nekih pojedinačnih vrsta. Dobijeni rezultati imaju hemotaksonomski značaj. Ispitana je citotoksičnost i antimikrobna aktivnost izolovanih alkaloida.

AB  - The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. Content of total phenolics, tannins, non-tannin phenolics and flavonoids was determined spectrophotometrically and content of gallic acid with HPLC. Antioxidant activity of the samples was assayed through FRAP (Ferric Reducing Antioxidant Power), DPPH scavenging test and inhibition of Fe2+/ascorbate induced lipid peroxidation. Extracts of native and thermally treated kernels showed high antioxidant activity, with extracts of thermally treated kernels being more active than extracts of native ones. Hydrolysable tannins and gallic acid were identified in all samples. Non-tannin phenolics, including gallic acid, were present in significantly higher quantities in thermally treated samples, whilst tannin content decreased. This indicates that during thermal treatment hydrolysable tannins were degraded. As the result of this degradation and consequent increase of non-tannin phenolics content, and amongst them especially gallic acid, thermally treated samples possess higher antioxidant activity than do the native ones. The obtained results have provided further grounds for establishing Q. robur and Q. cerris acorn kernels as a source for functional food preparation,
