Abstract
The leaves of Quercus championi yield hop-17(21)-en-3β-ol (Ia), hop-17(21)- en-3β-yl acetate (Ib), β-amyrenyl acetate, friedelin, and friedelan-3α-ol. Neither the hopenol nor its acetate have been obtained from plants before; nor has this acetate ever been obtained in a pure state before.https://doi.org/10.1071/CH9640697
