逆境胁迫下植物挥发油成分的研究进展摘要：植物挥发油在樟科、木兰科、腊梅科、姜科、菊科等科属的药用植物中均有分布，是中药重要的有效成分之一。
逆境胁迫指环境对植物的负面作用，包括高温胁迫、干旱胁迫、酸雨胁迫、盐胁迫等。
逆境胁迫会对植物的生长发育产生影响，进而影响挥发油等有效成分的堆积。
挥发油组分的分析方法很多，如气相色谱法、超临界流体萃取技术等，这些技术与红外光谱、质谱联用，可有效分析挥发油成分。
本文综述了各种胁迫下植物挥发油的成分变化的研究，以期寻找植物挥发油组分和含量的变化与逆境胁迫的内在联系。

Stress stress refers to the negative effects of environment on plants, including high temperature stress, drought stress, etc. Acid rain stress, salt stress and so on. Stress stress will affect the growth and development of plants, and then affect the accumulation of volatile oil and other active components. There are many methods for the analysis of volatile oil components, such as gas chromatography, supercritical fluid extraction technology, etc. These techniques, combined with infrared spectroscopy and mass spectrometry, can be used to analyze the constituents of volatile oils effectively. This paper reviews the changes of plant essential oils under various stresses. The purpose of this study was to find out the internal relationship between the changes of plant volatile oil composition and content and stress .Key Words: Adversity stress; naphthas; analytic procedure1.逆境胁迫概念胁迫指对植物产生伤害的环境，又称逆境。
胁迫作用指环境对植物的负面作用。
胁迫因素包括非生物因素和生物因素，其中非生物胁迫因素包括干旱、高温、酸雨、盐离子、重金属离子、养分胁迫等[1]。
不少学者发现植物的次生代谢物随逆境强度增加而增加[2]，如干旱胁迫对银杏中懈皮素含量的提高有促进作用[3]。
