Myricananone and myricananadiol: Two new cyclic 'Diarylheptanoids' from the roots of Myrica nana

Two new cyclic 'diarylheptanoids', myricananone (1) and myricananadiol (2), were isolated from the roots of Myrica nana, together with the known compounds myricanol (3), myricanone (4), and porson (5). Their structures were determined by spectroscopic methods, including 1D- and 2D-NMR as well as HR-ESI-MS analyses.
