| Popis: | The hexane extract of the aerial part of Artemisia annua yielded two bisnor-cadinanes, norannuic acid and qinghaosu I. The structures were elucidated by 400 MHz 1 H NMR, 2D NMR and mass spectrometry. The corrective 13 C NMR assignments of β-arteether, the potent artemisinin derivative, were performed on a 400 MHz instrument using HETCOR. |
