西南风铃草挥发油的化学成分分析

Analysis on chemical constituents in essential oil from Campanula colorata

西南风铃草（Campanula colorata Wall.）,又名岩兰花、土桔梗、土沙参,为桔梗科（Campanulaceae）风铃草属（Campanula Linn.）多年生草本植物,产于中国云南、贵州、四川和西藏,阿富汗和老挝等也有分布[1]。民间常以该种的根入药,主要用于治疗风湿、瘫痪、破伤风和虚痨咳血等[2]。有关风铃草属种类的研究多集中于生物学特性方面[3-4],对该属种类化学成分的研究报道尚不多见。

Chemical constituents in essential oil from Campanula colorata Wall. were analyzed by GC-MS technique. The results show that 76 peaks are detected in essential oil from the whole plant of C. colorata and 57 peaks are identified with accounting for 79. 48% of total peak area. Fatty acid（ 19. 38%） and ester（ 21. 78%） components are the main components,and there are some sesquiterpenol and monoterpenol components. The constituents with relative content over2% are 1,2-benzenedicarboxylic acid,butyloctyl ester,cedar camphor,hexadecanoic acid,dibutyl phthalate,tetradecanoic acid,caryophyllene oxide,6,10,14-trimethyl-2-pentadecanone and spathulenol.
