Deskripsi

Two new lindenane sesquiterpenes were obtained from the roots of <i>Lindera myrrha</i>. These compounds were structurally elucidated by HRMS data, extensive NMR analyses, and comparison between experimental and theoretical <sup>13</sup>C-NMR data. Myrrhalindenane A is the first monomeric seco-<span style="font-variant: small-caps;">d</span> lindenane displaying a non-rearranged, cyclohexanic C-ring. Myrrhalindenane B is the second occurrence of an angular lindenane-sesquiterpene related to a C<sub>6</sub>-C<sub>7</sub> lactonization.
