中文摘要： 目的 探究北沙参茎叶和根中挥发油的提取工艺，解析北沙参茎叶和根中挥发油所含化学成分，并初步评价其体外抗真菌活性。方法以水蒸气蒸馏法为基础，通过单因素与正交实验优化北沙参茎叶和根中挥发油提取方法，利用气相色谱-质谱联用（GC-MS）技术鉴定北沙参茎叶和根中挥发油所含化学成分并计算其相对百分含量。采用纸片扩散法测定北沙参茎叶和根中挥发油对茄病镰刀菌、半裸镰刀菌、尖孢镰刀菌、寄生曲霉和黄曲霉的抗真菌活性。结果北沙参最佳提取工艺为料液比1∶15，蒸馏时间5h，KCl浓度15%。从北沙参茎叶挥发油中鉴定出11种成分，根挥发油中共鉴定出8种成分。人参炔醇为北沙参茎叶挥发油和根挥发油的共有成分，其在茎叶中的含量为38.21%，根中的含量为74.02%。北沙参茎叶挥发油和根挥发油对茄病镰刀菌、半裸镰刀菌、尖孢镰刀菌、寄生曲霉和黄曲霉均有一定的抑制作用，以茎叶挥发油较强。结论北沙参茎叶挥发油和根挥发油的化学成分差异明显，但二者均具有一定的体外抗真菌活性。
英文摘要： OBJECTIVE To explore the extraction process of volatile oil from the stems， leaves and roots of Glehnia littoralis， analyze the chemical components of the volatile oil from the stems， leaves and roots of G. littoralis， and preliminarily evaluate its in vitro antifungal activity. METHODS Based on the steam distillation method， single factor test and orthogonal experiment were conducted to optimize the extraction method of volatile oil from the stems， leaves and roots of G. littoralis. The chemical components of the volatile oil from the stems， leaves and roots of G. littoralis were identified by using gas chromatography-mass spectrometry （GC-MS) technology and their relative contents were calculated. The antifungal activity of volatile oils from the stems， leaves and roots of G. littoralis against Fusarium solani， Fusarium incarnatum， Fusarium oxysporum， Aspergillus parasiticus and Aspergillus flavus was determined by paper diffusion method. RESULTS The optimal extraction process of G. littoralis was solid-liquid ratio of 1∶15， distillation time of 5 hours， and KCl concentration of 15%. Eleven components were identified from the volatile oil of the stems and leaves of G. littoralis， and a total of eight components were identified from the volatile oil of the roots. Ginsenethinol was a common component in the volatile oil from the stems， leaves and roots of G. littoralis， its contents in the stems and leaves， roots were 38.21% and 74.02%， respectively. The volatile oil from the stems， leaves and roots of G. littoralis had a certain E-mail：zwhjzs@126.com inhibitory effect on F. solani， F. incarnatum， F. oxysporum， A. parasiticus and A. flavus， especially volatile oil from the stems and leaves. CONCLUSIONS There is a significant difference in chemical components of the volatile oil between the roots， stems and leaves of G. littoralis， both of which have certain in vitro antifungal activity.
