摘　　要：目的:分析蚌兰花Rhoen discolor(L′Her.) Hance的挥发油化学成分。方法:采用水蒸汽蒸馏法提取蚌兰花的挥发油,并用气相色谱-质谱联用仪(GC/MS)对挥发油化学成分进行分析。结果:从蚌兰花挥发油中鉴定出了所有相对含量大于0.3%的20种化学成分,占总油量的92.96%。结论:挥发油主要成分为天竺葵醛,占总油量的25.72%,其余主要成分分别为棕榈酸(22.79%)、壬酸(18.94%)、月桂酸(7.72%)、异香兰醛(2.84%)、葡萄花酸(2.20%)、羊脂酸(1.89%)、亚油酸(1.71%)。Objective ： To analyze the chemical constituents of the volatile oil from the flowers of Oyster Rhoeo. Methods ： The volatile oil from the flower of Oyster Rhoeo was extracted by steam distillation and its chemical constituents were analyzed by GC/MS technique. Results ： All 20 compounds which relative content was greater than 0. 3% were identified, accounting for 90. 24% of the volatile oil. Conclusion： The major constituent of the volatile oil is nonaldehyde（25.72% ）, the other main constituents are hexadecanoid acid （22. 79% ） ,nonanoie acid （ 18.94% ）, dodecanoic acid （ 7. 72% ）, isovanillin （ 2. 84% ）, heptanoie acid （ 2. 20% ）, octanoic acid （ 1.89% ）and linoleic acid（ 1.71% ）, respectively.
