Klodorone A and klodorol A: new triterpenes from <i>Kleinia odora</i>

<div><p>Re-investigation of the EtOH extract of the aerial parts of <i>Kleinia odora</i> led to the isolation of two new triterpenes; klodorone A (<b>3</b>) and klodorol A (<b>4</b>), together with two known compounds: β-amyrin (<b>1</b>) and germanicol (<b>2</b>), which were reported from this plant for the first time. Their structures were determined by using extensive 1D (<sup>1</sup>H, <sup>13</sup>C and DEPT) and 2D (<sup>1</sup>H–<sup>1</sup>H COSY, HMQC and HMBC) NMR and mass spectral measurements in addition to comparison of their data with the literature.</p></div>
