Abstract
Two new tocopherol polymers, chroman-type dimer named ferotocodimer A (1) and spiro-type trimer named ferotocotrimer E (2), were isolated from the seeds of Euryale ferox. Their structures were elucidated on the basis of spectroscopic methods including HR-ESI-MS and 1D and 2D NMR. The absolute configurations of 1 and 2 were determined by CD and ROESY experiments.
