【摘要】 [目的]研究黄芩地上部分的挥发油的化学成分。[方法]用水蒸气蒸馏得到挥发油,运用GC-MS技术,结合计算机检索对具体化学成分进行了分析和鉴定。用峰面积归一法计算了各个组分的相对含量。[结果]分离鉴定了其中37个化合物,占挥发油总量的85.03%。[结论]黄芩挥发油中含量在3%以上的组分有:烯丙醇(5.53%)、苯乙酮(4.62%)、石竹烯(18.90%)、α-律草烯(3.99%)、香叶烯D(19.44%)、γ-榄香烯(6.23%)、1-乙烯基-1-甲基-2-(1-甲基乙烯基)-4-(1-甲基亚乙基)-环己烷(3.98%)。更多还原

【Abstract】 [Objective] The paper aimed to study the chemical constituents of the essential oil from Scutellaria baicalensis Georgi.[Method]The essential oil was obtained from steam distillation.Chemical components were separated and identified by GC-MS.The relative content of each component was determined by peak area normalization.[Result] Thirty-seven volatile compounds were isolated and identified,accounting for 85.03 % of the total oil.[Conclusion] The main compounds essential oil with contents over 3%(V/V) were as follows:Amyl vinyl carbinol( 5.53 %);Acetophenone(4.62%);Caryophyllene(18.9%);α-Caryophyllene (3.99%);Germacrene D(19.44%);γ-Elemene( 6.23 %);7a-dimethyl-4-(1-methylethenyl)-1,4-Methano-1H-indene,octahydro-1(3.98%).更多还原
