摘要

The volatile oil of tender leaves from brasenia schreberi was extracted through water vapour distillation method and the chemical composition was analyzed with GC-MS method. 55 separated and identified components took up 96.89 % of the peak area, which consisted of compounds of phenol,alkane, aldehyde, acid and alcohol, including methy-leugenol (25%), heptacosane (8.8%), 5-methyl furfural (8.0%), eucazulen (6.01%), carbamult (5.98%), cedrol (5.31%), π terpieol (3.77%), 4-terpineol (3.61%), cis-farnesol (3.36%), n-decanoic acid (3.35%), palmitic acid (3.01%), cis-6-dodecen-4-oli- de (2.8%), ethyl acetate (2.21%), eucalyptol (1.94%), f
