Phytochemical composition of the essential oil of different populations of Stachys lavandulifolia Vahl

Objective:To examine the chemical variability in inflorescences of wild populations of Stachys lavandulifolia Vahl(S.lavandulifolia)collected throughout two provinces(lsfahan 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 wereα-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%),△-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.

野艾蒿化学成分和药理作用研究进展

野艾蒿(Artemisia lavandulifolia)为我国传统中药,属于菊科(Compositae)植物,广泛分布于我国东北、华北等地区,具有巨大的开发潜力和丰富的资源。近年来,从野艾蒿中成功分离出许多具有新颖结构和显著药理活性的化合物,相关研究取得了显著进展。该文对野艾蒿的主要化学成分、提取分离方法、结构鉴定技术以及药理作用等方面进行了综合归纳总结。野艾蒿主要化学成分包括79个萜类化合物和挥发油、17个黄酮类化合物、6个木脂素类化合物和2个咖啡酸类化合物,还富含微量元素、维生素和氨基酸。野艾蒿化学成分具有显著的抗肿瘤、抗炎、抗氧化、降血脂、抑菌和杀虫等药理作用,但相关机制仍需进一步阐明。在此基础上,该文侧重关注野艾蒿的化学成分和药理作用,以挖掘更多具有临床价值的成分和作用机制。此外,该文也指出了野艾蒿在药用价值和现有研究方面存在的不足之处,并提出了未来的研究方向和建议,以促进野艾蒿的合理药用开发和综合利用,为今后相关研究提供参考和指导。
