野荆芥花挥发油化学成分分析

Study on the Constituents of Essential Oils of Flower from Elsholtzia stauntonii Benth

摘要: 目的研究采自河北承德地区的野荆芥(Elsholtzia stauntonii Benth)花挥发油化学成分。方法采用GC-MS技术和NIST质谱库对野荆芥花挥发油的化学成分进行分析和鉴定，用色谱峰面积归一化法计算各成分的相对含量。结果从该植物挥发油中分离出40个成分，鉴定了以4-异丙基-苯甲醇(48.32%)，2-甲基-5-戊酮(3)基-呋喃(22.87%)，2-甲基-5-异戊酮基-呋喃(6.40%)，β-石竹烯(3.00%)，2-乙基-5-异丁酮基-呋喃(3.56%)，氧化-β-石竹烯(3.46%)等为主的36个成分。结论这些成分为首次从该植物花挥发油中所发现。

Abstract: OBJECTIVE To study the chemical constituents of essential oils of flower from Elsholtzia stauntonii Benth．METHODS The chemical constituents of essential oils were identified and analyzed by GC/MS and area normalization method. RESULTS Thirty-six compounds were isolated and identified. These compounds concluded 4-(1-methyl ethyl)- benzenemethanol(48.32%), 2-methyl-5-pentanone(3)-furane (22.87%), 2-methyl-5-iso-pentanone-furane (6.40%), β-caryophyllene (3.00%), 2-ethyl-5-iso-butanone-furane(3.56%), caryophyllene oxide (3.46%) and so on. CONCLUSION These compounds were found from the flower of the plant for the first time.
