摘 要：目的研究北五味子种子挥发油的化学成分，并与其果实挥发油的化学成分作比较。

Research was conducted on the inhibitory effect of the volatile oil on several plant pathogenic fungi. Fungal colony diameter was measured in the inhibition experiments which indicated the presence of substances with antifungal activity in the roots of Tagetes patula. These results provide a valuable reference for development of fungicides.

方法］采用水蒸汽蒸馏法提取柱果铁线莲挥发油，通过气相色谱-质谱联用技术对挥发油的化学成分进行分析、鉴定。

GC-MS is used for comparative analysis on volatile oil extracted from wild and cultivated Valeriana.

应用GC-MS分析对比研究了野生与人工栽培缬草的挥发油，分别鉴定出52个和45个化合物。2种缬草挥发油的主成分基本相同，含量稍有差异，其差异对其在医药工业上的应用没有影响

The transplant of seedling should be processed after the upgrowth of leaves and root.By using the GC-MS, the chemical composition in root of Valeriana amurensis was analyzed. The avilid components in root of different provenance were similar, and the contents of effective composition in roots were depended on the provenance. Meanwhile, P-Panasinsene was founded in root of Valeriana amurensis for the first time.

用水蒸气蒸馏法提取黑水缬草根部挥发油，并用GC-MS联用仪对其化学成分进行了分析鉴定，结果表明：不同生境、不同产地、不同年份、不同生长方式的黑水缬草根部挥发油的主要化学成分大致相同，人工栽培的黑水缬草有效成分的含量高于野生黑水缬草有效成分的含量，并从中分离出一种在相关文献中未见报道的化学成分—β-人参烯。

Third, volatilizable parts from Hainan Rauvolfia were obtained through water vapor distillation. They were analyzed by GC/MS. The resuts showed that about 10 compounds in the root essential oil were extracted and 9 of them were identified. Fatty acids and phenol ramification are the main types of the compounds.

用水蒸气蒸馏法获得了萝芙木中的易挥发组分，对其进行了GC/MS分析，分析结果表明，萝芙木根挥发油分离出10个峰，鉴定出9种化合物，其主要成分为9-十八烷酸、十六酸，棕榈酸、9，12-十八烷二酸、1H－酚[2，1-b] 喃-1-酮，分别占挥发油总量的25.66%、19.34%、18.12%、17.23%，四者占其总量的80.35%。
