Abstract
A total of 38 volatile components were identified in Rhodobryum giganteum (Schwaegr.) Par. collected from two different geographic regions by headspace solid-phase microextraction (HS-SPME), combined with gas chromatography/mass spectrometry (GC/MS). The volatile components included some aliphatic and aromatic aldehydes, monoterpene hydrocarbons and a sesquiterpene (alpha-farnesene), with 1-methoxy-2-propyl acetate and n-hexanal being found to be the most abundant volatile components. Analysis of the chemical constituents in the volatile oil of the two samples showed that ten compounds were shared.
摘要
采用顶空固相微萃取（HS-SPME）结合气相色谱/质谱联用（GC/MS）技术，对采自两个不同地理区域的大灰藓（Rhodobryum giganteum (Schwaegr.) Par.）进行分析，共鉴定出38种挥发性成分。这些挥发性成分包括一些脂肪族和芳香族醛类、单萜烃类和一种倍半萜（α-法尼烯），其中乙酸1-甲氧基-2-丙酯和正己醛被发现是含量最丰富的挥发性成分。对两个样品挥发油化学成分的分析表明，共有10种化合物。
