Volatiles emitted into the headspace above flowering Mahonia japonica (Bealei group) (Fort.) Carr. plants were trapped using two methods: PDMS/carbotrap with thermal desorption and Porapak Q with solvent desorption, followed by GC/MS analysis. The complete GC/MS analysis of floral volatiles of M. japonica is presented for the first time, showing the predominance of benzaldehyde (4.1%), benzyl alcohol (14.0%), (E)-Î²-ocimene (57.0%) and citronellol (6.7%).
