摘要:

目的 研究浙产连钱草挥发油的化学成分。方法 水蒸气蒸馏法提取挥发油，应用气相色谱-质谱联用法(GC-MS)进行定性分析，按峰面积归一化法，求出挥发油中化学成分的百分含量。结果 挥发油鉴定出33个化合物，主要成分为石竹烯及其氧化物(25.14%)、早熟素Ⅰ和Ⅱ(12.58%)、喇叭烯(10.6%)、异松蒎酮(10.5%)、β-荜澄茄油烯(6.34%)，且油中含有一定量的反式斯巴醇(4.53%)、γ-榄香烯(4.68%)、β-榄香烯(1.45%)和D-柠檬烯(0.39%)。结论 浙产连钱草挥发油含有丰富的药用活性成分。

Abstract:

OBJECTIVE To study the chemical constituents of volatile oils from Glechome longituba (Nakai) Kupr. in Zhejiang province. METHODS The volatile oils were extracted by steam-stilling and were identified by GC-MS. Calculated the percentage composition of the volatile oils according to peak area normalization method. RESULTS Thirty-three compounds were identified. The major constituents of volatile oils were caryophyllene and caryophyllene oxide(25.14%), prococeneⅠ and Ⅱ(12.58%), viridiflorene(10.6%), isopinocamphone(10.5%), β-cubebene(6.34%), and (?)spathulenol(4.53%), γ-elemene(4.68%), β-elemene(1.45%) and D-limonene(0.39%) could also be found in volatile oils. CONCLUSION The volatile oils of Glechome longituba (Nakai) Kugr. groun in Zhejiang province contained abundant active medicinal ingredients.
