New Sesquiterpenes from Euonymus europaeus (Celastraceae)

A new sesquiterpene evoninate alkaloid (1), and two sesquiterpenes (2, 3) with a dihydro-β-agarofuran skeleton, along with three known sesquiterpenes (4—6), were isolated from the seeds of Euonymus europaeus. Their structures were elucidated by high resolution mass analysis, and one- and two-dimensi...

Zusammenfassung:	A new sesquiterpene evoninate alkaloid (1), and two sesquiterpenes (2, 3) with a dihydro-β-agarofuran skeleton, along with three known sesquiterpenes (4—6), were isolated from the seeds of Euonymus europaeus. Their structures were elucidated by high resolution mass analysis, and one- and two-dimensional (1D and 2D) NMR spectroscopy, including homonuclear and heteronuclear correlation [correlation spectroscopy (COSY), rotating frame Overhauser enhancement spectroscopy (ROESY), heteronuclear single quantum coherence (HSQC), and heteronuclear multiple bond correlation (HMBC)] experiments.
