Five New Triterpenoids from the Roots of Kadsura coccinea

A phytochemical investigation of an EtOH extract of the roots of Kadsura coccinea (LEM.) A. C. SM. furnished five new lanostane-type triterpenoids, coccinone A (1), coccinone B (2), coccinone C (3) coccinone D (4), and coccinilactone B (5). Their structures were determined based on spectroscopic analyses, including 2D-NMR experiments and HR-MS techniques.
