Some low‐volatile constituents of the absolute of Boronia megastigma (Rutaceae) from Tasmania were isolated and characterized. Besides β‐ionone ( 1 ) and many of its derivatives, e.g. 2–7 , we isolated the isomeric 3‐hydroxymegastigm‐7‐en‐9‐ones 8–10 and the megastigm‐7‐ene‐3,9‐dione ( 11 ). Furthermore, the p ‐coumaric acid derivatives ( E , Z )‐ 12 and ‐ 13 , alkyl esters of 8‐hydroxylinalool ( 16a–g ) and the N ‐[2‐(4‐prenyloxyphenyl)ethyl]tiglamide ( 17 ) were identified.
