Abstract: | Ten new highly oxygenated triterpenoids, kadcoccilactones A-J (1-10), and two known triterpenoids, kadsuphilactone A and micrandilactone B, were isolated from the stems of the evergreen climbing plant Kadsura coccinea. The structures of the new compounds were elucidated by spectroscopic evidence, with that of 1 confirmed by single-crystal X-ray diffraction analysis. This is the first report on nortriterpenoids (2, 4-6, 8-10) from the genus Kadsura. |
