摘　　要：采用超声波辅助石油醚提取法提取杨树芽中的脂溶性成分,得率为4.23%,利用气相色谱-质谱联用技术对其化学成分进行分析,分离、鉴定出51个化合物,已鉴定的化合物占总离子流色谱中出峰面积的88.45%,主要含有萜类36.46%、黄酮类14.72%、甾类13.78%、脂肪族类10.19%、芳香族类9.33%等化合物,这些化合物大多具有生物活性。The lipophilic constituents in poplar bud were extracted by uhrasonic wave assisted petroleum ether extraction method. The yield was 4.23 %. The chemical constituents of petroleum ether extract were analyzed by GC-MS. Fifty one compounds in extract were separated and identified, the identified constituents accounted for 88.45 % of the TIC peak area, mainly including terpenes 36.46 % , flavonoids 14.72 %, steriods 13.78 %, aliphatics 10.19 % , aromatics 9.33 % compounds, etc. and most of these compounds have biological activity.
