    目的：分析红木香药材根和果实中的挥发油成分。方法：采用气相色谱-质谱联用法。色谱条件：色谱柱为HP-5MS石英弹性毛细管柱，载气为高纯氮气，流速为0.9 mL/min，进样口温度为250℃，色谱柱初始温度为50℃(程序升温)，柱压为80 kPa，分流进样，分流比为40∶1，进样量为1.0 μL。质谱条件：离子源为电子轰击离子源，电子能量为70 eV，接口温度为230℃，质量扫描范围m/z 40～400，扫描间歇时间为1.0 s。结果：从红木香根的挥发油中总共检出43个色谱峰，鉴定出其中24个，占总量的91.5%；主要成分为倍半萜和单萜类化合物，其中(+)-δ-杜松烯、γ-毕澄茄烯和异朱栾倍半萜相对含量较高。从红木香果实的挥发油中总共检出52个色谱峰，鉴定出其中36个，占总量的82.2%；主要成分为倍半萜和单萜类化合物，其中石竹烯、γ-毕澄茄烯和紫穗槐烯相对含量较高。结论：该研究基本明确了红木香药材根和果实挥发油中的主要成分，并且二者存在明显差异。
