为探明黔产流苏石斛茎与束花石斛茎中的挥发油组成及差异，采用固相微萃取技术分别提取贵州兴义野生流苏石斛茎与束花石斛茎中的挥发油，GC-MS法对其化学成分进行分析鉴定和计算相对百分含量。结果表明：从黔产流苏石斛茎与束花石斛茎中分离鉴定出化学成分62个和54个，其相对含量占挥发油总量的97．66％和96．65％；两者具有相同的挥发性化学成分40个，其主要成分均含有β-波旁烯、δ-杜松烯、反-2-辛烯醛等；其中，流苏石斛茎挥发油中相对含量最高的为β-波旁烯（47．53％），而束花石斛中相对含量最高的为依兰油烯（19．397％）。

The chemical components and relative percentage composition of volatile oil of wild D. fimbriatum and D.chrysanthum collected from Xingyi,Guizhou were analyzed and calculated by solid phase microextraction (SPME)and GC-MS to study composition and difference of volatile oil between D. fimbriatum and D.chrysanthum.The results showed that 62 and 54 chemical components are isolated and identified from D.fimbriatum and D.chrysanthum respectively,and the relative content accounts for 97.66% and 96.65% of total volatile oil amount separately.D.fimbriatum and D.chrysanthum both have the same 40 volatility chemical components,and main components areβ-bourbonene,δ-cadinene and (E)-2-octenal,etc.Theβ-bourbonene content of D.fimbriatum is the highest (47.53%)while muurdene content of D.chrysanthum is the highest (1 9 .3 9 7%).
