To study the chemical constituents of the volatile oil from the rhizome of Anemarrhena asphodeloides.
The volatile oil was steam distillation. Chemical constituents were separated and analyzed by GC-MS. The relative content of each component was determined by area nomalization.
24 volatile compounds were isolated and identified for the first time, representing 70.83% of the total oil.
The main constituents of this oil were aldehydes (31.15%), terpene and their oxide (20.66%), alkyls (8.35%), Furan heterocyclic compounds (6.41%), non terpene alcohol (4.26%). There are 12 compounds with contents over 3%. Among them, borneol has the highest content (9.35%).
研究知母根茎挥发油的化学成分。
采用水蒸气蒸馏法提取挥发油，运用气相色谱-质谱联用（GC-MS）技术对化学成分进行分离和分析，通过面积归一化法测定各成分的相对含量。
首次分离鉴定出24种挥发性化合物，占挥发油总量的70.83%。
该挥发油的主要成分有醛类（31.15%）、萜类及其氧化物（20.66%）、烷基类（8.35%）、呋喃杂环化合物（6.41%）、非萜醇类（4.26%）。含量超过3%的化合物有12种。其中，冰片含量最高（9.35%）。
