目的采用气质联用技术(GC-MS)分析钩藤带钩茎、叶中挥发性成分,并比较所含挥发性成分的种类和含量。方法运用固相微萃取技术提取钩藤带钩茎、叶中挥发性成分,并用气质联用技术鉴定其成分。结果带钩茎中鉴定出50个挥发性成分,叶中鉴定出26个挥发性成分,其共有挥发性成分19个;带钩茎的主要挥发性成分有己醇(31.552%)、顺-3-己烯-1-醇(10.174%)、反-2-己烯醛(8.91%)、1-辛烯-3-醇(8.298%)、水杨酸甲酯(7.95%)、β-芳樟醇(6.528%),叶的主要挥发性成分有己醇(45.986%)、顺-3-己烯-1-醇(22.827%)、甲酸己酯(9.514%)。结论论钩藤带钩茎、叶中所含挥发性成分存在差异。
Objective To analyze the volatile components in the stems and leaves of Uncaria macrophylla with GC-MS and to compare the types and contents of volatile components. Methods Solid phase microextraction (SPME) was used to extract the volatile components from the stems and leaves of Uncaria macrophylla, and its components were identified by GC-MS. Results Fifty volatile components were identified from the stems with hooks, and 26 volatile components were identified in the leaves. A total of 19 volatile components were identified in the leaves. The major volatile components of the stems with hook stems were hexanol (31.552%), cis-3- (10.174%), trans-2-hexenal (8.91%), 1-octen-3-ol (8.298%), methyl salicylate Alcohol (6.528%), the major volatile components of the leaves were hexanol (45.986%), cis-3-hexen-1-ol (22.827%) and hexyl formate (9.514%). Conclusion There are differences in the volatile components in the hooked stems and leaves of Uncaria macrophylla.
