OBJECTIVE
To examine the chemical variability in inflorescences of wild populations of Stachys lavandulifolia Vahl (S. lavandulifolia) collected throughout two provinces (Isfahan and Chaharmahal va Bakhtiary), Southwest Iran.
METHODS
The essential oils of S. lavandulifolia Vahl from seven locations were obtained by hydro-distillation and analysed by gas chromatography and gas chromatography-mass spectrometry.
RESULTS
The results revealed that distinct differences in the content of compounds depending on region of sample collection. The main constituents of the essential oils were α-thujone (0.3%-32.3%), α-pinene (trace to 37.3%), myrcene (0.5%-15.9%), β-phellandrene (1.1%-37.9%), germacrene D (0.4%-11.3%), Δ-cadinene (trace to 11.6%) and 1, 4-methano-1 H-indene (trace to 10.1%).
CONCLUSIONS
The results of the present study indicated that essential oil components of S. lavandulifolia Vahl can be varied with genetic (ecotype), environmental conditions and geographic origin. In general, the essential oils of various populations of S. lavandulifolia Vahl were rich in monoterpenoids and sesquiterpenoids.
目的
研究伊朗西南部两个省份（伊斯法罕省和恰哈马哈勒-巴赫蒂亚里省）采集的野生薰衣草叶水苏（Stachys lavandulifolia Vahl，S. lavandulifolia）种群花序中的化学变异性。
方法
采用水蒸馏法从七个地点获取薰衣草叶水苏的挥发油，并通过气相色谱和气相色谱-质谱联用仪进行分析。
结果
结果显示，根据样品采集区域的不同，化合物含量存在明显差异。挥发油的主要成分包括α-侧柏酮（0.3%-32.3%）、α-蒎烯（痕量至37.3%）、月桂烯（0.5%-15.9%）、β-水芹烯（1.1%-37.9%）、吉马烯D（0.4%-11.3%）、Δ-杜松烯（痕量至11.6%）和1,4-亚甲基-1H-茚（痕量至10.1%）。
结论
本研究结果表明，薰衣草叶水苏的挥发油成分会因遗传（生态型）、环境条件和地理来源而有所不同。总体而言，不同种群的薰衣草叶水苏挥发油富含单萜类和倍半萜类化合物。
