TL;DR: The structures of the new pyrrolizidine alkaloids were determined by carbon and proton nuclear magnetic resonance and electron imoact and chemical ionization mass spectrometry as discussed by the authors.
Abstract: Methanolic extracts of Senecio triangularis Hook. (Compositae) gave a substantial amount of senecionine* (1) and small amounts of six other pyrrolizidine alkaloids, integerrimine* (2), platy-phylline* (3), rosmarinine* (12), retrorsine* (ll), and two new alkaloids, triangularine* (5) and neotriangularine* (6). The structures of the new alkaloids were determined by carbon and proton nuclear magnetic resonance and electron imoact and chemical ionization mass spectrometry. Triangularine is 7-[(Z)-2-methylbut-2-enoyl]-9-[(Z)-2-hydroxymethylbut-2-enoyl]retronecine aid neotriangularine is 7-[(Z)-2-methylbut-2-enoyl]-9-[(E)-2-hydroxymethylbut-2-enoyl]retronecine.

TL;DR: Ruder et al. as discussed by the authors identified 7-angelyl-retronecine, 7-senecioyl-9-sarracinyl-9 rCtronCcine and 7-sedecilel-7 sarracyl-7 rctroncine as new natural products.
Abstract: Deportment of Chemisty. The Utliversih, Calgny, Alta., Cntlndn T2N IN4 Received May 2, 1983 H. RUEGER and M. H. BENN. Can. J. Chem. 61, 2526 (1983). Pyrrolizidine alkaloids were isolafed from Setlecio trirrtlg~rlaris Hook, growing in Alberta, and identified as 7-angelylretronecine, 7-senecioylretronecine, 7-angelyl-9-sarracinylretronecine, and 7-senecioyl-9-sarracinylretronecine, the last three of which appear to be new natural products. H. RUEGER et M. H. BENN. Can. J. Chern. 61, 2526 (1983). On a isolC les alcaloides du type pyrrolizidine du Setlecio trinng~tlnris de Hook croissant en Alberta et que I'on a identifies comme 6tant I'angClyl-7 rCtronCcine, la sCnCcioyl-7 rCtronCcine, I'angClyl-7 sarracinyl-9 rCtronCcine et la sCnCcioyl-7 sarracinyl-9 r~tronicine; les trois derniers composCs sernblent Ctre des nouveaux produits naturels.
