| Abstract: | The volatile component in mulberry(Morus albs Linn.) leaves was obtained by microwave assisted extraction(MAE) associated with solid-phase microextraction(SPME), then separated and identified by gas chromatography-mass spectrometer(GC-MS).Forty-five compounds were identified. The main constituents of the extract from mulberry leaves were found to be ketones (6.56 %),alcohols (33.32 %),acids (13.71 %), alkanes and alkenes(23.44 %), sterols,aldehydes,esters and heterocyclic compounds. The main compounds were: 3,7,11,15-tetramethyl-2-hexadecanol (24.05 %), 1-acetyl-4-isopropyl-bicyclo3.1.0]hexane(16.27 %),5-(2-isobutylenyl)-4,6,6-trimethyl-3-cyclohexenyl acid (8.35%),3,7,11,15-tetramethyl-2-hexadecen-1-o1(5.67 %). MAE-SPME-GC-MS is convenient, rapid and reliable for analysis of volatile constituents in mulberry leaves. |
