%X The hopane triterpenoid in the extractives from P. mougeotiana, reported in Part VII1 of this series as hopane-6&#945;,7&#945;,22-triol, is now shown to be hopane-6&#945;,7&#946;,22-triol (1j). There is a consequential revision of the two triol diacetate structures to hopane-6&#945;,7&#946;,22-triol 7-acetate (1i) and hopane-6&#945;,7&#946;,22-trio1 7-acetate (1h). In addition the diol reported as hopane-11&#946;,22-diol has now been shown to be a mixture of hopane-7&#946;,22-diol (1b) and hopane-15&#945;,22-diol (1e). Hopane- 7&#946;,22-diol 7-acetate (1f) and hopane-15&#945;,22-diol 15-acetate (1g) have also been identified in the extractives.
