【摘要】采用水蒸气蒸馏法从桂枝、白术及其药对中提取挥发油成分,通过气相色谱-质谱(GC-MS)联用技术对其进行分离检测,结合直观推导式演进特征投影法(HELP)对重叠色谱峰进行分辨解析;同时,利用程序升温保留指数辅助定性.研究结果表明:从单味药桂枝、白术及其药对中鉴定出66,29和55个组分,分别占挥发油成分总量的94.43%,95.93%和96.35%;单味药与药对共有4种组分,占药对挥发油总含量的13.14%;组成药对后,新增4种组分,单味药桂枝消失33种组分,白术消失7种组分;药对中挥发油主要成分是2-(2-甲氧基)苯甲氧基苯酚、γ-芹子烯和桂皮醛等,它们主要来自于白术;药对种类与含量变化并不是单味药的简单相加,其作用机理有待进一步研究.%The volatile constituents were extracted from Ramulus Cinnamomi(RC), Atractylodes macrocephala(AM) and herbal pair(HP) RC-AM by steam distillation. Using gas chromatography-mass spectrometry (GC-MS) combined with heuristic evolving latent projections(HELP), a useful chemometric resolution method which can be used to resolve overlapping peaks in chromatogram, was employed to identify and comparatively analyze the volatile constituents,together with the temperature-programmed retention index for assistant identification. The results show that there are 66,29 and 55 kinds of constituents of the essential oils being identified respectively from single herb RC, AM and
HP-RC-AM, and the relative amount accounts for 94.43％, 95.93％ and 96.35 ％ of the total relative contents in order.There are 4 common volatile constitutions in single herb and HP, and accounting for 13.14％ total contents in HP. There are 4 components increasing in HP, while there are 33 and 7 components losing in the single herb CR and AM respectively. The volatile principally components in HP are 2-(2-Methoxyphenoxy)phenol, γ-Selinene and Cinnamaldehyde, et al., and they are mainly from single herb AM. Their relative kinds and amount in HP are not equal to the two single herbs, whose reaction mechanism in HP should be studied further.
